The technical FIELD

This invention relates to dental prostheses, dental arches and methods for their manufacture. In particular, this invention concerns improvements in upper and lower dentures, clinical and laboratory methods for their manufacture, materials and equipment.

The LEVEL of TECHNOLOGY

When lost or for one reason or another, removed all the teeth, for example because of the drugs atrophy, due to disease or old age, are required artificial teeth. The most common form of artificial teeth with complete edentulism are removable dentures. Usually they include a full set of upper and/or lower teeth, usually without wisdom teeth. The size and shape of the prosthesis to provide their location on the soft tissues of the jaw, called oral comb. Are used around the world hundreds of millions of dentures.

Thanks to advances in materials the dentures are more durable, have acquired a more natural look. The development of design solutions improved convenience and efficiency of mastication of food. However, the process of prostheses in clinical and laboratory conditions for decades has changed little, and because the prostheses must be tailored individually to each patient, they may not be the subject of mass is proizvodstva. Therefore, the manufacturing process remains simultaneously and costly, and time consuming. In addition, the patient experiences discomfort due to delays associated with the manufacture of the prosthesis, and the prosthesis is already made, the patient again may experience discomfort due to poor fit of the prosthesis caused by the mismatch of occlusion of the jaws, clinical and laboratory errors, including related failures that occur in the manufacturing process.

The traditional process of manufacturing the prosthesis typically includes repeated consultation with a practicing physician, and for each visit to a practitioner should work, performed by a dental technician. Very often the room or laboratory dental technician removed from the doctor's office. Therefore, the impressions, casts, and especially articulatory apparatus used for the manufacture of prostheses, it has to be transported back and forth between the doctor's office and dental laboratory technology. This increases the delay in the manufacture of prostheses and leads to additional transport and laboratory expenses, ultimately, a doctor and, therefore, of the patient.

After an initial assessment of the condition of the patient, the process of manufacturing the prosthesis begins with performing the initial impressions of the top and bottom of the mouth using a standard impression spoon. The primary who's prints are sent to the dental technician. He makes plaster casts of which makes an individual impression tray for the patient. Individual tray guide the dentist, he is using this spoon makes a second casts. Then the technician makes the secondary casts from plaster and makes them a wax occlusion rollers to determine the occlusal arrangement of the jaws. Using these rollers is set up and fixed jaw relationships (occlusion). Then wax occlusal rollers temporarily connected together in accordance with the position of the temporomandibular joint and taking into account the Central and vertical dimensions, provided that, as a point of reference adopted occlusal plane and the location of the fangs. Sometimes doctors use orthodontic face-bow and even more complex systems of articulation, showing a scrupulous regard to the design of the prosthesis to the patient. Wax occlusal rollers then back to technique. The technician places the rollers on the articulator (apparatus for reproducing movements of the lower jaw) and tracks labels and dimensions drawn on the rollers for accurate setting of the teeth (dentition). There are many different articulators accuracy, complexity, and cost. Unfortunately, don't always use those articulators, which would provide the best financial p is tat. Selected for the patient artificial teeth must be installed by a dental technician, one after the other exactly in accordance with the dimensions prescribed in wax occlusal rollers. Then meticulously sculpted and purified wax base with the established number of teeth is returned to the doctor for trying on her patient.

At this stage, the teeth can have the desired appearance and to meet the physiological dimensions. Often, however, the doctor has to face the fact that the bite made not accurately or teeth set askew, i.e. there are aesthetic or functional difficulties. Such problems can be caused by incorrect interpretation of one or more of the factors necessary to determine the exact relative position of the jaws of the patient. This can happen because of the wrong done by the doctor's actions and/or inaccurate and/or unstable position of the jaws of the patient during his previous visit. Other problematic factors can occur in the laboratory equipment due to incorrect preparation for the execution of works or the Protocol execution. In addition, the possible physical effects on the teeth. There are likely manifestations and other factors leading to change one or more materials or snap, for example, during transportation or due to temperature sensitive feature : the reality of wax foundations of the dentition or damage another kind. If such problems arise, a tooth system with the established number of teeth must be returned equipment to remove all artificial teeth and re-installation of artificial teeth. This means that lost the results of all large-scale works that are related with the definition of the occlusal relationship of the jaws, articulation, installation of the dentition and manufacturer of wax cast. Re-made wax Foundation established number of teeth is returned to the doctor for trying on her patient. This process is repeated up until the doctor and the patient will not be satisfied with the result. Only after that the dental technician can move on to the final stage of the work and make the final prosthesis. Remember that every time when a technician receives from the dental prosthesis for correction before starting to work, he has to wash and sterilize.

The final stage is an intensive process that takes a significant period of time. The final prosthesis is made or polymethyl methacrylate, or acrylic polymers of methyl methacrylate or other acrylic polymers, using traditional molding in the molding dental ditch, injection molding or vulcanization method ultraviolet light flux. So, negative (reverse) plaster the hotel from wax with dentition is made in a ditch. In the gypsum and/or on its surface add release liquid or separating grease to create incapable of adhesion layer between the uncured acrylic polymer and the surrounding plaster and/or plaster model, to allow removal of the hardened, in the end, acrylic polymer, when the manufacturing process in the cell is completed. During fabrication of the plaster model in a ditch in it add soft polymetylmetacrylate acrylic compound and compressed to increase the density. The excess is removed, then pressed again prior to heating in order to start the chemical reaction, leading to hardening of the compound. Depending on the type of compound, the heating process can last from one to eight hours. After cooling, the prosthesis is released from the cell, cut off, give fastone outline the edges of the gums near the teeth and polished before sending to the prosthetist. Other manufacturing methods may also be used, such as the aforementioned injection molding or process using ultraviolet radiation to cure the composite material.

The patient wears dentures, checks the correct fit of the prosthesis, accurate bite, identify whether there is pain or undesirable deviations of dimensions, such as premature contact, in any place, not to the same way whether the prosthesis. Checked also aesthetic factors.

If problems exist and may not be effective in the clinic, the prosthesis should return equipment to perform additional adjustments up until the prosthetist and the patient will not be satisfied with how well-fitting prosthesis and its appearance.

If the process goes smoothly, then the total time spent on its production, including the work of the prosthetist and equipment (excluding travel time between the clinic and laboratory)shall be not less than thirteen hours.

Another disadvantage of the traditional method of manufacture of the prosthesis is that in case of unsuccessful final work, the prosthesis must be redone from the beginning to the end, because it made fatal mistakes on the most important stages of its manufacture. If, for unforeseen reasons, attempts adjustments did not result neither in the laboratory nor the doctor when the patient is sitting in a chair, the device is recognized as absolutely void. The damaged prosthesis should be considered a marriage and time-consuming process of fabrication of a new prosthesis should be repeated in full. Even in the absence of an incorrigible specific damage dentures on average need to be replaced every five years or so because of physiological atrophy of the alveolar ridge of the mouth, which leads to depletion or change eniam the surface of the tissue and cause discomfort.

Numerous attempts to improve the efficiency of methods of prostheses, clinical methods, design of the prosthesis and/or the quality of their composition. However, none of the attempts did not significantly accelerated and/or improved clinical methods, design of the prosthesis, the method of manufacturing a prosthesis and/or the above-mentioned problems.

The IMPLEMENTATION of the INVENTION

Below will be described the structure of the dental arches and accessories in accordance with this invention, as well as ways the s of prostheses, using these dental arch.

Figure 1 - 3 shows the base 10 of the dental arch, performed in accordance with this invention. The base 10 includes a metal elongated element 12 having a curvature, basically repeating the curvature of the dental arch. Tooth arc may take various forms depending on the form of the patient's mouth, which this tooth arc intended. For example, the arc may be conical, square, oval or other shape. The size of the arc also depends on the size of the patient's mouth, the definition of which will be discussed below in connection with another aspect of the invention.

The elongated element 12 includes an intermediate section 13 between the front section 16 and each of the rear sections 20, with the front section 16 is gradually bent and goes into the rear areas 20. In accordance with certain variants of the invention, the element 12 is twisted so that its front side 14 becomes essentially parallel to the front surfaces of the artificial teeth in the dental arch. In embodiments of the invention shown in figure 1 - Figure 3, the front surface 14 of the front section 16 is almost perpendicular to the front surfaces 18 of the rear sections 20 of the element 12. The mutual location of the facial surfaces of the base 10 and the surfaces of the artificial teeth are described below in rassm the friction Figure 4.

In accordance with the variants of the invention shown in figure 1 - Figure 3, the elongated element 12 includes a bend 22 between the front section 16 and each of the rear sections 20. Front section 16 changes the form and enters the rear sections 20 approximately in the place where is Fang. In the region of the second small posterior tooth (second premolar) the plot becomes almost horizontal plate and in the field around the first and second large posterior teeth (molars) becomes essentially horizontal and flat. Each of the rear sections 20 includes a relief surface 24 containing a through hole 26. For attaching artificial teeth to the base 10 using composite materials, such as curing with ultraviolet light polymers or any acrylic polymers, as will be described below. Textured surface 24 and through holes 26 help mechanical retention of material attached to the base 10.

In accordance with a preferred embodiment of the invention, the base 10 is made of a single piece of high-strength metal to provide the required strength and stiffness of the dental arch and made her prosthesis. The base, made from materials such as titanium or high strength metal, not easily bend or distort when normalnom use, in addition, it is biologically compatible. You can use and other biocompatible metals and alloys for the manufacture of the base 10, such as stainless steel or metals with high carbon content. It also appears that for the manufacture of the base 10 in metals can be used, and other biocompatible materials having sufficient strength, such as ceramics, one or more polymers, fiber composite materials or carbon fiber materials.

As can be seen from Figure 4, arc tooth 28 comprises a base 10 with a set of artificial teeth 29 (except wisdom teeth). The teeth attached to the base using the composite material 30, or other material, such as cross-linked acrylic. For the sake of clarity. Figure 4 shows a portion of the base 10 with the adjacent teeth in half section, with arc tooth 28 and the base 10 are not shown. The front surface 14 of the front section 16 of the element 12 in generally parallel the front surface 31 of cutters 32. The front surface 18 of the rear sections 20 of the element 12 in generally parallel (one or more) chewing occlusal surfaces of large artificial posterior teeth 34 and/or small teeth 36. Therefore, the base 10 provides the strength of the dental arches is 28, meet the forces of chewing muscles, which usually have to face.

In a variant, reflected on Figa, artificial teeth 29 secured to the element 12 in predetermined fixed positions constantly.

Figure 5 shows an axonometric view of the base 10 of the dental arch in accordance with another embodiment of the invention, the rear view of the aforementioned base 10 shown in Fig.6. In this embodiment of the invention, the base 10 includes a number of holes 26 in the element 12. Holes are made in the front section 16 and the rear portion 20 of the element 12 in predetermined places, but not in the intermediate sections 13, which fit the curves of the 22 elements 12 is elongated. Holes 26 provide free fixing of artificial teeth on the base 10, so you can adjust their position on the base 10. Details about this will be discussed in the description of Figure 9 and Figure 10.

7 shows the upper dental arch 38, made in accordance with another embodiment of the invention. In this embodiment, at least some of the artificial teeth 40 are installed in the holes 26 and attached to the element 12 by means of fastening means (not shown). Some artificial teeth 40, in particular, bordering the intermediate section in place of the bend 22 in the element 12 attached to it, using the receiving acrylic polymer 30 and/or composite material and/or other material.

On Fig shows one artificial tooth, the cutter 32, attached to the front portion 16 of the element 12 through the openings 26 so that the holes 26 remains for other fastening artificial teeth. It should be borne in mind that Fig upper denture is upside-down, so the cutter looks up. In accordance with the invention, the base 12 to the lower dental arch has a similar structure except that the size of the other and correspond to the smaller size of the lower dental appliance. For example, the front part of the lower dental apparatus is smaller than the front part of the upper dental device.

In accordance with the invention, an artificial tooth 40 (see Figure 9 and Figure 10) has a rear channel 42 with the screw groove 44 for receiving the threaded end 46 of the screw 48. The screw 48 may be made of acrylic polymer or metal, such as titanium, although you can use other have the same strength materials. The channel 42 has a rear wall 43, the upper surface 45 and the bottom surface 47. The height of the channel is greater than the height of the element 12 is elongated base 10. As can be seen from Figure 10, the artificial tooth 40 is located on the base 10 so that the portion of the element 12 enters the channel 42 can abut tightly or loosely in the rear wall 43, the upper surface 45 and the bottom surface 47. An artificial tooth 40 is held in place in the element 2 by means of a screw 48, passing through the hole 26 in the element 12, which is in line with the tooth, and are screwed into the groove 44. The hole 26 has a width and height greater than the diameter of the rod 49 of the screw 48, but smaller than the diameter of the head 51 of the screw 48. It is necessary, first, to ensure passage of the screw through the hole 26 and, secondly, to ensure that the teeth 40 can be installed quite easily in range of different positions and angles, and at the same time, it is not possible to easily move or remove the tooth from the base. Therefore, the vertical position, lateral position and angles of the artificial teeth can be adjustable relative to the apertures 26. This ensures a high degree of maneuvering to achieve the desired appearance and position of the front teeth on the dental arch and in the prosthesis, manufactured on its basis. In the example shown in Figure 10, the front side of the artificial tooth 40 is installed freely and abuts against the front surface 14 of the element 12.

In an alternative embodiment, the groove 44 and the screw 48 may not have threads. In this case, the groove may be made in the form of a socket, which includes an elongated end of the fastening element 48. Mentioned elongated end can be accurately associated with the form of the nest. For this purpose it is performed so elastic that, as is provided in the socket, elongated end linked with it, is formed of elastic contact.

On Figa shows another mounting option. A groove is made in the rear wall 43 of the artificial tooth 40 in the form of a nest W, forming a small cone. The end V rod 49 of the fastening element 48 has the same conical shape, and its dimensions correspond to the groove W. The end W is held in the socket B, but can be removed by hand, if you pull the head 51 with sufficient force. The slot in the cylinder 51 for tightening the screw in this case is not required.

On Figa - Fig.10F shows various examples of the position of the teeth on the base 10 and the angles.

Two artificial tooth 29A, 29B, presented at Figo, freely mounted on the base 10 by means of fixing elements 48A and 48V. While the front surface 31A of the tooth 29A mainly parallel to the front surface 14 of the element 12 and the front surface V tooth 29B is at an angle relative to the front surface 14 of the element 12.

On FIGU shows a slit up the side of the artificial tooth 29, freely mounted on the element 12. The rod 49 of the fastening element 48 passes through the opening 26 and tightly fixed in the groove 44 of the rear wall 43 of the channel 42. In this embodiment, an artificial tooth 29 is inclined forward with respect to the element 12. The arrows indicate the various directions in which the tooth 29 can be move is relative to the element 12.

Figs illustrates how artificial teeth 29 may be podvinut relative to the element 12, to change the angle of the front surface 31 of the tooth relative to the front surface 14 of the element 12.

Fig.10D shows how artificial teeth 29 may be podvinut forward and backward relative to the element 12, to vary the degree of extension of the front surface 31 of the tooth from item 12.

File illustrates how artificial teeth 29 can be rotated around the axis of the fastening element 48 to change the angle of the tooth relative to the vertical V and with respect to item 12.

On Fig.10F shows a portion of the base 10 and six artificial teeth 29 mounted freely on the element 12 and held in place with appropriate fasteners 48. Shows the options for location of the teeth relative to the element 12. The middle line indicate the degree of rotation of each tooth relative to the vertical and show the corners of the front surface 31 relative to the element 12. Also on Fig.10F shows the angles, different degree of extension of the front surface 31 of the tooth of the element 12 and the overlap of two adjacent teeth on each other. The blocks 55, shown in the foreground schematically illustrate the position and orientation of each tooth 29. Such a large range of possible orientation allows you to set the tooth in almost any desired position.

When the desired position of the tooth 29 is defined, it can be temporarily locked in this position by means of wax, or the tooth may be installed in a more permanent position through the use of acrylic polymer capable of samootverzhennyy, or by using the composite material 30, the curing of which is influenced by irradiation with ultraviolet light. This guarantees the preservation of the selected patient and physician aesthetics (Fig.10G).

Alternative embodiments of the mounting artificial teeth shown in Fign, Fig.10J and FIGC. An artificial tooth 600 contains many signs that have already been described above, in particular the channel 42 having a rear wall 43, the upper surface 45 and the bottom surface 47, the height of the channel 42 is greater than the height of the element 12 of the base 10. However, unlike previous versions of the wall 43 instead of the groove 44 has a protruding element 602. An artificial tooth 600 is held in place on the element 12 by means of the mounting element 604 passing through the hole 26 in the element 12, which is in line with the tooth 600. The hole 26 has a width and height greater than the diameter of the rod 49 of the fastening element 604, but less than the diameter of its head 51. In this embodiment of the invention opposite the head end of the fastener 604 contains the slot 606 for coupling with the speaker the SIP 602 artificial tooth 600. The protrusion 602 may include an expanded end, the shape of the slot 606 of the fastening element 604. In this case the nest is made elastic, so that the extended end being inserted into the socket grips with it. Wall 608 of the nest may contain one or more notches 610 facilitate the execution of this elastic coupling. The length of the projection 602 and, consequently, the depth of the slot 606 may vary in different implementations. In some cases, the protrusion 602 is advanced from the rear wall 43 of at least 1 mm, and in this case, the depth of the slot is not less than 1 mm.

In accordance with certain variants of the invention, the angle of inclination of artificial teeth 29 on element 12 can be adjusted (Figa - Fig.11D), changing the position of the vertical angle and mesiodistally overlay, as shown for tooth 29A on Fig.10F. On Figa shows the dental arch containing artificial tooth 29 mounted on the far side of the element 12 on the front side of the element 12 no artificial teeth. Artificial cutter 32 is fixed on the front part 16 of the element 12 at an acute angle with respect to the almost horizontal element 12. As a consequence, the cutter tip is noticeably protrudes forward. On FIGU artificial cutter 32 is located essentially vertically and compared with Figo the tip of the cutter is directed more to the inside of the side lips. On Figs the tip of the cutter 32 to an even greater extent directed inwards towards the lips. If necessary, the tooth 32 can be set so that its tip will protrude even more significantly (Fig.11D)than is shown in Figa.

The size of the dental arch 28 is selected in the range corresponding to the size of the mouth, i.e. dental arch can be small, medium and large. In addition, the following describes what dental arch may have other dimensions. Also provides a variety of forms of the dental arch 28, to fit the shape of the patient's mouth. Dental arch 28 can be, for example, square, round (or oval), conical, or other shape. It depends on the degree of curvature of the jaw. Dental arch 28 is mounted on the base 10 of the same form.

Another aspect of this invention is the bow-shaped element 50 (Fig), designed to determine the size of the dental arch. The element 50 may be made of transparent plastic material and is subject to sterilization. Arcuate element 50 comprises a pair of front holes 52 to the left and to the right of the arm 56, indicating the location of the left and right canines. Arcuate element 50 also includes at least one pair of rear holes 53, indicating the location of the large molars. A pair of second holes 53 determines the place of the races whom the provisions maialino-convex tubercles of the first large molars, the left and right. In accordance with some variations of the invention (Fig) arcuate element 50 may include a second pair of rear holes 54 to specify the location of the second large molars, left and right. In particular, the second pair of holes 54 located behind the holes 53 and determines the position of the Central fossa of the second large molars. According to some versions of the invention the arcuate element 50 comprises a pair of front holes 52 and a pair of rear holes 54. Arm 56 is of arcuate element 50 to facilitate its use. Arcuate element 50 can be used directly in the patient's mouth or on a model.

On Fig shows one set of arcuate elements 50 that are used to determine the size of the dental arch. Each arcuate element 50 corresponds to a size of the dental arch. Arcuate element 50 on Fig labeled with the number "4"which indicates the size 4 of this item. In the structure presented on Fig, the position of the pair of holes 52 relative to the pair of holes 54 on each arcuate element 50 corresponds to the size of the dental arch. For example, in the schema (structure), which contains five dimensions of dental arches, there are five different arcuate elements 50. The smallest size, size 1, is relevant to the duty to regulate the inner perimeter, formed by a pair of holes 52 and a pair of holes 54 of the arcuate element 50 (Fig). The largest size, size 5, corresponds to an external perimeter formed by the pair of holes 52 and a pair of holes 54 of the arcuate element 50 (Fig). Intermediate sizes correspond to the internal perimeters, which lies between the smallest and the largest sizes. In accordance with some variations of the invention adjacent the perimeters on Fig removed from each other by 1 mm horizontally and 1 mm vertically. However, there are other dimensions mentioned distances.

On Fig shows the model 58 of the lower ridge and the location of the 60 second molars, location 61 maialino-convex tubercles of the first molars and the location 62 fangs.

It should be borne in mind that the structure is not limited to five different sizes of the dental arch. For example, the structure may contain three, four or more, five arcuate elements 50 respectively three, four and more than five dimensions of the dental arch. In the structure containing three sizes, respectively small, medium and large.

In accordance with certain variants of the invention, the arcuate element 50 contains one or more labels 57A, 57B, adjacent to the holes 52. In fact, with any of the marks 57A, 57B fangs Lee the t on one line, you can judge the shape of the curve of the arc. For example, if the label 57A lies on the same line with fangs, it indicates the square shape of the arc. If the label 57B lies on the same line with fangs, it indicates conical shape of the arc. In some cases, labels 57A, 57B is made in the form of apertures in the arcuate element 50.

Another aspect of the invention concerns a system for determining the size of the dental arch. The system contains a set of arc-shaped elements 50, each of which has a pair of holes 52 in the left and right front section of the element 50 to indicate the location of the teeth, and at least one pair of holes 53, 54, left and right rear section of the element 50 to indicate the location of the molars. The mutual location of the front pair of holes 52 and rear pairs of holes 53, 54 corresponds to the size of the dental arch. In particular, a pair of rear holes 53 indicates the location maialino-convex tubercles of the first molars, left and right. As already mentioned, in some cases, each arcuate element 50 may also or alternatively have a second pair of rear holes 54 behind the pair 53 to indicate the location of the second molars, left and right. In particular, the second pair of rear holes 54 determines, for example, the location of the Central fossa of the second molars.

the other aspect of the invention is a method 70 determine the size of the dental arch, using the above system. On (Fig) presents a schematic representation of the sequence of procedures of method 70. In accordance with the method 70 is one of the arcuate elements 50 are placed on the dental arch (item 72). Then determine whether a pair of holes 52 and the first and/or second rear openings 53, 54 in line with the location of the canines and molars, respectively (item 74). It is at this stage you can choose the alignment marks 57A, 57B to define the shape of an arc, as described above. If this is not done, the method allows the selection of another form arcuate element 50 at step 76, then repeat steps 72 and 74. After a pair of front and/or rear openings 52, 53, 54 are aligned with the positions of the canines and the molars, the method provides for the assessment of the quality of fit of the installed arc-shaped element 50 (item 78). If this arcuate element 50 is not good enough, then again choose arcuate element 50 of a different size and repeat steps 72, 74 and 78. The size and shape of the dental arch (item 80) is determined based on the arc-shaped element 50, which is better than all the others is consistent with the positions of the canines and the molars. At this stage you can also define suitable for use with the color of artificial teeth.

In accordance with another aspect of the invention (Phi is .16) for making it more elastic and strong prosthesis is not cured (uncured) a flexible sheet 90 of composite material with a flexible reinforcing mesh. On Fig shows the components of the flexible sheet 90 disassembled. The sheet 90 includes a composite material, such as flexible acrylic polymer, built-in reinforced biocompatible mesh 92, for example, from biologically compatible glass. Despite the fact that the flexible sheet 90 is made as an integral unit ready for use, the said sheet 90 can be manufactured by compressing reinforced mesh 92 between two layers 94, 96 of the composite material, as shown in Fig. As will be described in detail below, the composite material 94, 96 is currently used for the manufacture of prostheses and reinforced mesh 92 new flexible composite sheet 90 increases the strength of the grounds dentures.

An additional aspect of the invention is depicted in Fig. This long stretch of 100, made of flexible acrylic composite material in the form of dental apron. Dental apron contains a number of arcuate profile 102 to align them with the tails of artificial teeth 29 toothbrush installation prior to completion. Dental apron is also used prior to final fabrication of the prosthesis to align mentioned cut from a composite collar surrounding the arch. For example, curved profiles 102 can be aligned with the cervical areas of artificial teeth 29. External is again a dental apron also contains polyommatinae substance, therefore, the outer layers have a certain rigidity. Dental apron contains many relief or convex sections 104, called testenum views of the gums and the Foundation of their native structure. Dental apron can be used to quickly generate about lip festoons and vertical bending of the prosthesis, i.e. in cases when you want a smooth pair of adjacent surfaces, in particular of artificial teeth of the dental arch with artificial gingiva using a composite material, to give the prosthesis a natural appearance. Make a set of aprons of different size according to different dimensions of the dental arches. Dental apron increases the effectiveness of prostheses, as compared with the traditional manual method of doing festoons when using the apron requires much less time.

Dental apron may also be made of rubber for reusable markup or wax for traditional wax model. This apron has a number of curved notches 102 to align with artificial teeth when it is used to run festoons around the dental arches that are already installed in the required position. In such cases, dental apron is made in several versions with different size with respect to arcs of different sizes. Dental apron, and in this case, the AE increases the efficiency of the prosthesis by reducing time in festoons, compared with the traditional manual method.

In accordance with another aspect of the invention a dental apron can be made by pressing acrylic composite cut 100 or wax into the mold in the form of pescanova module. Felony module is an elongated metal strip having on the surface a negative image, which forms the convex sections 104 on acrylic plastic composite material 100. The strip may be of rubber or wax. The result labial apron with scalloped or prints, ready to use.

Fig and Fig illustrate another aspect of the invention. Shown cushioning insert 110 for use in the simulation of oral ridges. The insert 110 has an arcuate shape close to the shape of the lower ridge of the mouth, and contains a very transparent gel 112 in a sealed outer layer 114. As shown in Fig, the cross section of the insert 110 of the lower ridge is essentially U-shaped. The insert 110 is fabricated in a range of sizes corresponding to the sizes of impression spoons, described below. For example, by analogy with the above-mentioned dimensions of the dental arches insert 110 is made or in three sizes - small, medium, large, or four dimensions, five dimensions, for example from the first to the fifth, or even more which of sizes. Dotted lines on Fig illustrate the plasticity of the insert 110 in the area of the lips and tongue that allows you to precisely place it around the language, to fit to the mouth area and uneven gingival furrows.

On Fig shown lower impression spoon 120 to simulate the lower ridge of the mouth. The tray can be sterilized. It can be made of any suitable material, such as transparent impact-resistant plastic, better highly transparent in its natural state. Impression spoon 120 has an arcuate shape close to the shape of the dental arch, and contains the handle 122 to facilitate its use. The tray 120 is fabricated in a range of sizes in accordance with one of the following schemes. On Fig shows the impression spoon size 4 the schema containing five sizes.

On Fig represented by the cross-sectional view of the insert 110, shown in Fig, and impression spoons 120, shown in Fig, in the situation of their use in order to make an impression of the ridge 124. The cross-section of the bottom of the spoon 120 has an essentially U-shaped. On Fig also shows the ridge 124 of the tooth cavity of the patient and the layer of composite material 126 on the crest. The insert 110 is placed on the impression spoon 120 and lies between the composite material 126 and spoon 120. Plastic shock-absorbing insert 110 ensures that the composite of the first material 126 is tightly in contact with the ridge 124 and provides accurate impression of the ridge 124 without distortion, without pain and harm to the patient. Plastic shock-absorbing insert 110 prevents excessive pressure on the tissue, which could distort the parameters of the ridges and to displace them. A hand-held emitter 128 ultraviolet waves are used for curing composite material 126 on the solid structure of the patient's mouth to hold an impression of the ridge 124. After removing it from the mouth you can use a larger emitter 130 ultraviolet waves for complete curing of the composite material 126, after which it is fully installed.

Top impression spoon 123 (Figa and 20B) are made of the same material as the lower impression spoon 120, it is made to obtain forms for molding the upper tooth ridge and palate. Top impression spoon 123 contains the handle A to simplify its use. The shape of the upper impression spoons 123 corresponds exactly to the upper dental ridge and the hard palate. The tray 123 is fabricated in a range of sizes in accordance with one of the following schema.

Shown in Figa plastic shock-absorbing insert 125 has the same characteristics as the insert 110 (Fig and Fig)described above, and is used with the upper impression spoon 123 for forming the upper tooth ridge and palate.

On Figa shows the cross section of the insert 125, shown nafiga, and impression spoons 123, shown in Figa, during their use when taking the impression of the ridge of the mouth and palate 124A beaches. The cross-section of the upper impression spoons 123 is M-shaped. On Figa shows the layer of composite material A on all surfaces of the tongue and palate 124A beaches. The insert 125 is placed on the upper tray 123 and lies between it and the composite material A. Plastic shock-absorbing insert 125 ensures that the composite material A tightly in contact with the ridge 124 and provides accurate impression of the ridge 124 without distortion, without pain and harm to the patient. Plastic shock-absorbing insert 125 prevents excessive pressure on the tissue, which could distort the parameters of the ridges and to displace them. A hand-held emitter 128 ultraviolet waves are used for curing composite material 126 on the solid structure of the patient's mouth to hold an impression of the ridge 124A beaches. After removing it from the mouth you can use a larger emitter 130 ultraviolet waves for complete curing of the composite material A, after which it is fully installed.

Method 200 of manufacturing a prosthesis in accordance with the invention will be described with reference to the block diagram of the algorithm is shown in Fig and Fig.

The implementation of the method (200) begins with a consultation (205) of the patient at the dentist is to review the medical aspects of the patient's health and condition of his teeth. Then determine the size of the dental arch of the patient (210)using the above system, containing a set of arc-shaped elements 50 (Fig - Fig). The size of the dental arch of a patient can be classified as small, medium or large, if you are using a circuit containing three sizes. If you use another scheme, for example, contains five dimensions, the sizing may be some intermediary, such as a size 4.

The method (200) also includes a procedure (215) define the shape of the dental arch of the patient, the arc may be cone-shaped, square or oval. Experienced prosthetist may determine the form of the dental arch of the patient's eye. Otherwise, it can be determined according to the drawings shown in Fig for one particular size. Fig - this is just an example, other sizes, shapes and formats are also possible. At this stage, the dentist in consultation with the patient can also determine the approximate shape of the patient's teeth. Teeth can be cone-shaped, square and oval. In addition, the teeth can be rectangular, narrow rectangular or asymmetrically tapered. Examples of the forms of the teeth shown in Fig. At the same time determine the colour of the teeth.

The next step (220) is to select individual dental arches 28 for the upper and lower bases of which will be made about the ez. After selecting the dental arches exact size and shape make the final decision on the size, shape, color and shade of the teeth of the patient. In accordance with some variations of the invention, this step includes the process of updating occlusal vertical distance (OVD) and the height of the bite (RVD).

The method also includes determining occlusion and occlusion of the patient and their assignment to one of three classes. On Figa shows normal occlusion (Class I) vertical overlapping the lower teeth of the upper and horizontal overlapping of the dentition in the range of 1-3 mm Figv shows normal occlusion, in which the vertical overlap of more than 3 mm Class II is prognathism a bite in which the horizontal overlap is greater than the vertical, as shown in Figs. Class III is a bite in which the lower teeth protrude forward and as a result, the cutters can be stacked edge to edge, as shown in Fig.25D. The dentition may have teeth with flat ends, with the tabs incomplete height or physiologically natural ledges, which are determined by the available height or physiologically due to atrophy of the remaining lower ridges 124.

For patients with this situation dental arc also make cross-lateral occlusion, while the lower jaw to one side of the Bo is the more and forcing back chewing teeth on this side to be more convex, than the upper arc. The upper curved ends correspond to the center of the hollow rear lower teeth, and under normal circumstances, they would match the curve of the back of the lower teeth.

On Five dental arc in accordance with the invention can have a shape adapted to different types of balanced occlusion. On File shows some types of balanced occlusion, namely: monoplane, fluid type, lingual occlusion, almost proper closure, the correct closing.

In an alternative embodiment of the invention, the dental arc can have a shape adapted to different types of curvature of the occlusal plane. These include, for example, lateral occlusal curve Spee, curve of Wilson and the curve of Monson.

Step 225 includes a procedure for obtaining the impression of the ridge of the mouth and palate. In accordance with some variations of the invention this can be done using plastic composite sheet 90 (Fig) and insert 110, 125 from the gel, and the lower occlusal spoons 120, 123, shown in Fig-21, 18A, 20A, 20B and 21A. Plastic composite sheet 90 match with upper and/or lower crest, depending on what is required. You usually need both, because the patient wants to have and the maxillary and mandibular dentures. In accordance with some variations of the method (200) comp the attributes material formed directly on the ridge 124 and the upper sky. With the aim of rapid manufacturing solid upper and lower bases material utverjdayut using ultraviolet radiation, after which the base adjust to the parameters of the oral cavity without the traditional materials used for prints of models.

At this stage, if desired, you can make an imprint of the old denture patient, using traditional dental viscous mass. After it hardens, you can make the base, imposing on her net a blank sheet of composite material, prescovia it and Podravina peripheral areas using a pointed instrument. Then the base utverjdayut ultraviolet radiation and straighten peripheral areas. More manufacturing bases described below when considering Fig - Fig.

Sometimes you want the upper base 134 and arch 28 (Figv and 26C) is stably set in the mouth of a patient temporarily, for example to attach to the flange 124 using dental adhesive materials. In this regard, the method provides for the procedure of 230 printed on the upper base 134 small balls or lumps 132 of the curing light composite material in multiple positions, for example in the canine and first posterior tooth, with nominal height is exceeded. Alternatively, the small ball is or lumps 132 of the curing light composite material can be pressed into the same locations of the upper dental arch 28, contains the base 10, is selected for the patient, as shown in Figa. Each contact tip lumps 132 may be applied to composite adhesive gel, ensuring adhesion to the base and lower part of the arc. If the doctor prefers to first install the lower arc, this is possible too. To do this, the lower arc accurately set and otvetit, then on a lower arc place and fix the upper arc on the bottom. Then the balls 132 are placed on the upper arch and the base, the patient is asked to close his mouth and keep it closed until, until you have reached the desired position.

Despite the fact that the upper arc 28 is attached to the upper base with the help of lumps 132, the latter have not yet been solidified. Therefore, the method provides for the adjustment of the doctor provisions of the dental arch 28 relative to the upper framework 134 (step 235)to achieve precise centering and accurate occlusal positions, as well as the desired aesthetics for the patient. Doctor-prosthetist can move and manipulate dental arch 28, as required, and can also control the distal region: not formed there corking.

To the desired position of the dental arch 28 relative to the bases 134 is maintained stably carry out the curing lumps 132 (step 240). Thus there are two possible ways: either by using ultraviolet what about the diffuser is exposed to the oral cavity and utverjdayut all composite lumps at the same time, or utverjdayut each of the lumps individually using traditional hand held ultraviolet emitter. On Figa and Figv shows the dental arch 28, attached to the upper substrate using a hardened lumps 132. There is shown a marker 137 bumps of a tooth crown, token Fang 138, the Central marker A and line 139 of the rear cavity, which can be used for alignment of the dental arch 28 with the upper base 134.

Step 245 of the method consists in checking the plane of occlusion and Central positions using tools such as ink plate, or any other traditional methods currently used to determine the plane of occlusion. For some reason, the position may not be accurate due to bias or other errors. For example, could not be cured or not until the end of the fixed lumps 132, which led to fuzzy fixing positions. Then perform step 250) separate arch 28 from the upper base 134 and repeat steps 235, 240 and 245, until you get the exact relative position of the arc 28 and the upper base 134.

Once achieved the accuracy of all positions, perform step 255. From the mouth of the patient removed the upper base 134 attached to the dental arch and carry out the correct interdigitation of the lower arc with the teeth of the upper the arc, i.e. mentioned arc is positioned so that the bite was right. The lower arc temporarily fasten the upper arc in exact position using molten adhesive wax.

Then (step 260) in the mouth of the patient is placed structure, consisting of three parts. This upper base 134 attached to the dental arch 28 and the lower arc attached to the upper arc in a state of proper occlusion. The bottom base is also placed in the mouth and well attached to the flange 124 dental glue.

After this exercise (step 265), a careful check of occlusal relationship of the jaws, until you are convinced that achieved accurate alignment and mutual positions of the lower and upper jaws and, therefore, grounds. This makes sure that the lower jaw and the temporomandibular joint are dormant. The patient must be sure that the correct position will be saved when you re-actions, without any premature contacts and difficulties.

The next step (step 270): multiple composite lumps 132 is placed between the lower dental arch and the lower base, for example, in the area of the canine and the first posterior tooth. Composite pellets can be placed on the lower arch, or on the bottom base. Each contact tip of the ball may be caused to composite adhesive gel to ensure that the respective adhesion to the base and lower part of the arc.

In step 273, the patient slowly closes his mouth, so that the lower dental arch, which is now part of the three units of the whole, took the exact position, and to maintain proper interdigitation. At the same time checks the plane of occlusion, the centering position and occlusal vertical distance.

Then (step 275) and have a local vulcanization (curing) of the lower composite lumps, then the structure 160, consisting of four parts, is removed from the patient's mouth (Figs). The sequence of formation of structure 160 is as follows: the upper base 134 is connected with the upper dental arch 28 using the upper composite lumps, the upper arc 28 is connected with the lower arc 28A using melted wax 161 and the lower arc 28A connected to the lower base 136 with the lowest composite lumps. Then remove the wax, fastening dental arc, and separating the upper base and the upper arc from the bottom of the base and the bottom of the arc by the end of the arcs. All remaining areas of compression and occlusion of melted wax is removed. Now the structure 160 is ready for pilot testing of the bite and the adjustment of the prosthesis before the final stage of its manufacture. It should be noted that in the process of removing his mouth structure 160 of the four parts of the wax may break down, or be displaced, but it n the matter. Structure 160 of the four parts can be removed in the form of two separated parts, the top and bottom. This is possible because each of these parts contains a base and an arc, which is now steadily fixed hardened composite lumps.

The next step (280) is that the lower and upper base 134, 136 with attached dental arcs 28 and 28A return again in the mouth of the patient, and then check the fit, contact closure and occlusion, alignment and appearance of the prosthesis, asking the patient to open his mouth and close his jaw (step 285).

When this check of the plane of occlusion, the centering position, occlusal vertical distance and RVD.

If there are any unstable unstable malocclusion or relating to this problem, the method comprises the step 290, which is the separation of the lower dental arch 28A from the lower base 136, and repeat all the steps ranging from step 255. If all positions are accurate, and the doctor and the patient is satisfied with the result, the upper and lower dentures are removed from the patient's mouth and divide them (step 295). Removing dental adhesive used for attaching the base to the ridge and the upper surface of the oral cavity and thoroughly clean the bottom of the grounds.

Then the doctor prosthetist decides how to complete the prosthesis (SAG), whether in the traditional way, or in accordance with the invention to use composites. The continuation of the method 200 in accordance with the composite method reflected on Figa. This is a step 305 of the algorithm. The continuation of the method 200 in accordance with the traditional method reflected Figv. This step 340 algorithm.

For the continuation of the Method 200 in accordance with the composite method (step 305) on the upper and lower base 134, 136 is applied is capable of samootverzhennyy composite gel. Then the base is placed again in the mouth of the patient and ask him to hold the base in a fixed position until the gel is partially cured to a solid consistency. The first stage of curing usually takes 2-3 minutes. The gel until it is soft, can leak out, filling the grooves surrounding the peripheral ledges of the grounds, creating a natural cushion around the grounds and providing them with more accurate pavement for the final fit.

Then the upper and lower dentures are removed from the mouth of the patient (step 310) and put them in a device for emitting ultraviolet energy, where they are fully otverzhdajutsja. Now the dentures are ready for the final stage of processing. Thus, clinical counseling of the patient and the physician was placed in one visit.

At this stage, the prosthesis can be sent to a dental laboratory for completion of the work, or this is can be done by the doctor in the clinic with the use of ultraviolet radiation for full cure.

The following procedure (step 315) is that both filled prosthesis composite material in the language and lip areas, as shown in Fig.27D. For completion of the work, and give them a natural look you can use a piece of 100 acrylic plastic material in the form of dental apron with scalloped shown in Fig. The superficial layers of the composite material is spilled to the outside and edges are blurred, forming a smooth transition between hard and soft composite compounds. Scallops can be performed manually (File) by cutting out a triangular wedge 164 of the composite sheet and placing them on each neck of the tooth to resemble the root structure. On Fig.27F the prosthesis has a scalloped only partially, half the base 134 is not yet equipped with festoons. Thickness created from composite materials around the peripheral areas may vary depending on the desired effect. Diamond glitter can be obtained by applying the last of the outer layer. This means that the prosthesis does not require mechanical polishing.

Then (step 320) in denture add element 140, having a form retaining jumper penetrate the body, made on the upper base side of contact with the tissues. This element is used to improve retention of the upper denture on the upper surface of the UAV is odara strength improved tightness. The example which penetrate the body and its use is discussed below in the description Fig - Fig.

Then both prosthesis return to the procedure of UV curing (step 325), and then the prosthesis is subjected to conventional procedures to bring them in order: polished, sterilized, after which they are ready for the second and last visit to the clinic (step 330).

Step 335: the doctor is doing the fitting of the finished prosthesis, if it is revealed that in some place the patient feels pain, the doctor carries out the necessary correction and the process is complete.

In accordance with the invention, the prosthesis is made from the upper base 134 and bottom 136, respectively, containing upper arch and the lower dental arch, which is enshrined in the grounds in one of the proper items. The prosthesis may be manufactured by any known method: using dental cuvette, by injection molding or by using composite materials. If desired, you can save time by applying at the final stage of the manufacturing method of adjustment using the curable by ultraviolet radiation of the composite. When this composite type in the language area of the denture and mouth area using a composite dental apron, described above (Fig)

If the doctor-prosthetist uses the traditional method (Fig is), the method 200 includes a procedure 340 accurate impressions of the ridges, using greater precision rubber material for the base of the stamp, as it usually would in the process perebazirovka prosthesis. This process consists in the following: in the mouth of the patient is kept low back and get an impression of the upper jaw, asking the patient to close the mouth to a pre-fixed vertical position and make sure the bite, the position of the teeth and centering normal. The process is repeated for the impression of the lower base.

Once both of the impression made on a clear retainer material, the method 200 provides step 345. The casts are removed from the mouth, rinse and wash in the sterilizing liquid and sent to a dental laboratory for fabrication of wax models and perform final cleanup procedures as if it was the process of perebazirovka or recovery of the prosthesis. At this stage (step 350) the prosthesis is made in the laboratory by standard methods. The finished dentures are put in order, polished, sterilized (step 355) and return to the clinic. In the clinic (step 360) carry out the fitting of the prosthesis in the mouth of the patient and if necessary make adjustments. The process completed.

In accordance with an alternative embodiment of the invention the method comprises the steps 205 through 225, as described what about the above when considering Fig. Then initially made the casts can be formed model from traditional materials in the clinic or laboratory.

Of these models can be cast upper and lower base. If you do not use traditional occlusal rollers, then you can perform the steps 230 through 335 of the Method 200, as described above.

In an alternative embodiment, method 200 using traditional wax occlusal ridges after receipt of all sizes on wax and markup in the form of markers attached to each other of the upper and lower wax occlusal ridges sent to a laboratory for proper articulation and installation of dental arches 28.

Therefore, dental arc can be supplied both to a doctor and technique in the laboratory. Dental arc set, strictly observing the correct interdigitation. Install quickly, placing the upper arc in one step in accordance with markers occlusive roller, and then place the bottom arc, strictly observing the correct joining with the upper arc. Wax all the way around rollers merges with composite acrylic material 30 of the dental arches 28. Rollers give pestanya shape using wax variant of the apron, as described above with reference to Fig. Rollers are sent to the clinic for fitting the patient and fit. Then the realization of the ways the and 200 can be restored with step 280, as described on Fig - Figv.

Fig illustrates embodiments of another aspect of the invention. Pressed element 140 with pressing the tip is made in the form of a retaining jumpers installed on the upper base 134. Element 140 increases the width of the soft palate between the left and right cusps of the upper crests of the vibrating line, it is attached at the rear part of the upper base-side contact with the tissues. This improves the retention of the upper denture in the sky. Element 140 is a layer of composite material containing two adjacent tapering section 142 having lateral sides 144 and point 146 protruding from the base 145 of the element 140. Each segment 142 has a rising profile 143 along a line passing from the point 146 to the base 145, with the rising profile decreases in height towards each side 144.

Thus, in some embodiments, a portion of the connection node 400 are in contact at three points, with the possible movement in the range of about 7 in any direction from the centre.

Described here are the links of machine production made with tight tolerances to ensure accurate fitting of the parts of the base 10 and the execution of their relative movement in one plane only.

On Fig and Fig shown attached to the base 10 of the artificial teeth made in accordance with some variations of the invention. Attach artificial teeth, as shown in Fig, can be made as separate units, or as blocks 440, containing several artificial teeth 442. Mentioned blocks may contain front teeth (the front blocks 444) or posterior (back) teeth (rear blocks 446). In the shown Fig examples front block 444 contains six artificial teeth 448, and two rear block 446 contain four art is the result of tooth 450 each. In a preferred embodiment, the artificial teeth 442 and the field of artificial gums 443 made of such material as acrylic polymer.

In accordance with the invention attached artificial teeth can be applied to any substrate 10. For example, on Fig shows the base 10, containing less visible in the back part of the hole 26, intended to capture the two rear blocks 446. In the front part 16 to the base 10 is attached by a single artificial teeth 40 with fasteners 48 passing through holes 26, as described above. In this way, individual configuration of the prosthesis in a more visible front. However, if desired, a single artificial teeth can be used in rear areas 20 regardless of which teeth are installed in the front part 16.

In some embodiments of the invention the base plate contains artificial teeth mounted on it in the form of dentition, while the base contains one or more places for them to mount. In these places can be mounted either individually isolated teeth and blocks of teeth. In the alternative case of a single artificial teeth 40 are secured on the base 10 at one or more locations using a fixing element 48 passing through holes 26.

Additional examples of block 440, aderrasi artificial teeth and intended for installation on the upper and lower substrates 10 as in the front sections, and back shown in Figa. On Figa shows the blocks containing three, six and seven artificial teeth 442, but this number can be anything from a single tooth to a complete set. The sizes and shapes of blocks 440 are determined by the size and shape of the dental arch of the patient. Sizes can be three: small, large and medium, or they may correspond to the above-described scheme and change from number 1 to number 5. Among the applicable forms are wedge-shape, oval and square. Depending on the wishes of the patient can be selected color and color shades of artificial teeth 442, moreover, a matter of choice are the shape of the tips of the teeth, their height and angle.

Additional details regarding the attached artificial teeth will be described with reference to Fig and Fig. On Fig shows a cross section block 444 with the front teeth, is fixed on the base 10. Block 10 has a through hole 26, but it is not used to attach the block 444 to the base 10. Block 444 contains the channel 452 against the rear wall 454, form the shape of the front surface 14 of the front section 16 of the base 10. Channel 452 has a curved upper surface 456 and a curved bottom surface 458 to align with the curved upper and lower surfaces of the base 10, the height of the channel 452 also agreed with you the Auteuil Foundation 10. However, the height of the holes 460 of the channel 452 is less than the height of the base 10, so that the block 444 is latched in the base 10. Hole 460 has rounded edges 462 to facilitate smooth latching the base 10 in the channel block 452 444.

On Fig shows a rear view of the cross-section of the rear block 446, attached to the base 10. Block 446 contains the channel 463 with the base, form the shape of the bottom of the rear portion 20 of the base 10. Channel 463 has a curved side surface 466, 468 to align with the curved surfaces of the base 10, with the width of the channel 463 are also consistent with the width of the base 10. However, the width of the openings 470 channel 463 less than the width of the base 10, so that the block 444 is latched in the base 10. Hole 470 has rounded edges 472 to facilitate a smooth latching the base 10 in the channel 463 rear block 446.

In accordance with another variant of the invention dental blocks 440 may be attached to the base 10 using the existing holes 26. For example, in the alternative, or rather, adding to the aforementioned channels 452, 463 blocks 440 may include tabs (not shown)that can be inserted through corresponding holes 26 in the base 10. The protrusion may have an elastic end to connect with a snap. If necessary, the elastic end can be compressed, so that is bigcity it is removed from the base.

On Figa shows another embodiment of a dental blocks 440 and, in particular, the rear block 446. In this embodiment, can be used to secure the unit at the base of the fastening element 10 650, passing through one or more holes 26 in the base 10. Such a method is described for the operation of fastening teeth (Figure 9 and Figure 10). On Figa shows the screw 650 through a hole 26 in the base 10 into the slot 652 in the rear block 446, threaded. The base 10 may include a recess 654 for placement of the head of the screw 650. Note that the screw 650 and nest 652 thread can be used as an alternative biologically compatible adhesive means, or in addition to them.

It describes options for fixing artificial teeth should add the following. Artificial teeth can include an elongated slot or channel for placement of the base 10 so that the teeth can be slipped onto the base. For example, artificial posterior teeth, made in the form of blocks, shown in Figa may include elongated channels along the opposite inner walls of the blocks.

The shape and dimensions of elongated channels provide for placement of the base 10, for example, essentially horizontal flat rear sections 20 of the base. In this example, the rear blocks containing artificial memory is s, pulled over the rear sections 20 of the base 10, the corresponding areas of the first and second molars. Provided also that the front blocks with artificial teeth can contain upper and lower elongated channels to accommodate the front portion 16 of the base 10.

Additional aspects of the invention will be described with reference to Fig - Fig. They relate to the production versions of the bases and methods of making dentures. At least some of the following methods useful in cases where the prosthesis has been damaged, lost, or if the patient first needs prosthesis.

On Fig shows the impression spoon 500 for the manufacture of lower denture containing attached to the handle 502. The handle 502 may be made of any metal or plastic, but the preferred material is stainless steel. The handle 502 may be embodied in several slits 504 in a tablespoon of 500, as shown, or it can be fixed using one or more of a vulcanized light crude lumps of composite material. Impression spoon contains 500 holding slicing 505 for sticking to her base 10 and artificial teeth. On Fig shows the impression spoon 506 to make the upper prosthesis containing removed from the slots 504 handle 502.

Impression spoons 500 and 506 can be made about the relatively quick and simple, using a mixture of standard dental putty and catalyst. At this place the mixture directly on the existing upper and/or lower denture(s) or to an existing model. Alternatively, spoon 500 and 506 can be made in a similar fashion, using reinforced acrylic polymer, such as polymethylmethacrylate (PMMA), or other polymers, including polypropylene, if you make traditional prints grounds.

Also as an alternative impression spoons 500 and 506 can be made relatively quickly and easily by placing a mixture of reinforced plastic composite material 90, as described above, directly on the existing upper and/or lower denture(s). If dentures are not, mixture reinforced plastic composite material 90 can be placed on the crest of the patient's mouth and gently pressed against the ridge. Composite material with the imprint of the shape of the ridge is subjected to vulcanization light and handle edges to quickly obtain the upper and/or lower impression spoons 500, 506, prepared individually for the patient. Impression spoons 500, 506 can then be used in the manufacture of precision dentures, using base 10, false teeth and a vulcanized lumps of composite material, and the realization of how articulatory control the way the lower and upper dentures, above.

As can be seen from Fig, impression spoons 500, 506 can be filled with two-phase composite material 508 silicone-based, such as Ufi gel Gel supplied by the Corporation VOCO, USA, or other materials to get the impression from the crest of the oral cavity of the patient. Can be used, for example, a material based on rubber. Then the prosthesis can be completed on the spot, or they are sent to a dental laboratory.

On Fig shows the production version of the upper impression spoons 506 of the composite material. Impression spoon 506 contains plastic reinforced biocompatible mesh 92. As can be seen from Fig and rear view presented on Fig at least part of the grid 92 spoons 506 is open. In the initial state of impression spoon 506 contains a flexible reinforced net vault 510 without composite material. The size and shape of the mesh of the code vary for different patients. The inventor has found that flexible reinforced net vault 510 provides precise adjustment of the upper spoons, consequently, the upper denture individually for each patient. Separate the top and bottom sheets 512, 514 not soft flexible vulcanized composite material mounted on the upper impression spoon 506 on the net code 510 on the top and bottom and fasten using any approach is asuu technology fasteners, for example, using liquid adhesives. Then the body of the prosthesis can be accurately formed in accordance with the unique code of the patient regardless of any bone-palatal anomalies, and then perform his cure light. In order to achieve a comfortable fit and not to waste material waste, avoid excessive thickness of the arch.

On Fig shown round rod 516 of composite material, which can be attached to the periphery of the upper impression spoons 506 in any suitable way. Do order a good seal around the edges of the mouth of the patient.

In accordance with some variations of the invention, in the initial state of impression spoon 506 may not contain a composite material, as well as the arch 510. In these cases, the impression spoon 506 contains a flexible reinforced mesh hem 518. You can then around the mesh edges 518 on the periphery of the upper impression spoons 506 to secure the round rod 516 of the composite material. Do order a good seal around the edges of the mouth of the patient.

The lower impression spoon 500 can also include a flexible, reinforced mesh skirt lip and/or linguistic region spoons 500 to achieve a snug fit to the patient's mouth. To different thicknesses of the ridges in the oral cavity of the patient can be adapted to provide the desired thickness and shape to positng material around the periphery, increasing the precision fit and making the prosthesis comfortable.

Additional embodiments of the invention shown in Fig - Fig. On Fig presents axonometric arcuate element 700 for use with upper and lower impression spoons, such as spoons 500, 506. Arcuate element 700 may be performed as described above when considering Fig - Fig arcuate element 50. Arcuate element 700 includes protruding above the plane of the handle 56 and a lot of pair of holes 52 in the left and right front sections close to the arm 56, and at least one pair of rear holes 53 in the left and right rear sections. Arcuate element 700 has a Central hole 702 and 704 of the cut on each foot 706 between the front holes 52 and the rear holes 53. Along the lines 704 706 feet can be trimmed to reduce the size of the arcuate element 700 in accordance with the size of the patient's mouth. Arcuate element 700 may be performed in a range of different sizes, for example, you may have five sizes in accordance with the above scheme. On Fig also shown is the removable connector 708, which are inserted into the holes 52, 53 for attaching the arcuate element 700 to spoon, as described below.

On Fig shown enlarged axonometric view of the connector 708, which is th can be inserted into the arcuate element 700. The connector 708 includes a housing 710, provided with a protrusion 712. The protrusion 712 has a wide end 714 and a narrow portion between the end 714 and the housing 710 connector 708. The protrusion 712 may be made of elastic material so that you can enter it in the arcuate element 700, at least partially through one of the holes 52, 53, as shown in cross-section (Fig). The perimeter of one of the holes 52, 53 can cover bottleneck 716 and hold the connector 708 in the hole. In some versions the connector 708 contains adhesive material 718 printed at the bottom of the housing 710 to attach the connector 708 to the top or bottom of the spoon, as shown in Fig. Adhesive material 718 may be covered with a removable lid 720 to its astringent properties are preserved until use. In the alternative case, the connectors can be attached to the top or bottom of impression spoon using a biocompatible glue.

On Fig shows the top impression spoon 506 containing a pair of connectors A attached to the rear section of the spoons, and the connector B, ready to attach to the front section of impression spoon. Arcuate element 700 is then affixed to the connectors A, B through the holes 53 and the Central hole 702, respectively. In an alternative embodiment, the connectors A, B can sleep the Ala to be inserted into the holes 53, 702 arcuate element 700, and then glued to the impression spoon 506. Top impression spoon 506 (Fig) contains a flexible reinforced net vault 510 and flexible reinforced mesh skirt 518. On Fig shown lower impression spoon 500 containing a flexible reinforced mesh skirt 518, impression spoon ready to attach the arcuate element 700 using connectors 708.

Thus, the base 10, the dental arc 28, dentures, arcuate elements 50, the insert 110, 125 pressed element 140 in the dental prosthesis, and more, are described here aim to address some of the aforementioned problems in this area. Problems are solved by a significant reduction in the time required for the manufacture of dentures for the patient and significant reliability layout of the dentition, as well as ensuring quality and strong limbs. Dentures can be made, usually for two visits. In addition, the process is more accurate, because the design of the prosthesis uses a natural articular apparatus of the patient, rather than the traditional mechanical articulary device. Dental arc 28 containing the base 10 and reinforced plastic flat composite material 90, provide additional strength and durability of the prosthesis. The method of fitting the dental arches to the top and the bottom is much easier than known methods. Accurate fitting of the dental arches to the grounds is a physician-prosthetist using natural jaw of the patient in one session. When using intricate mechanical articulators (apparatus for reproducing movements of the lower jaw) achieved significantly worse results. In accordance with the invention, any errors clinical procedures quickly identified and easily eliminated during the same session without the intervention of a dental laboratory.

Frequent transportation casts rollers for determining the occlusal relationship of the jaws, the fitting is fully installed artificial teeth opposed to the way that substantially reduce these difficulties and in some cases completely eliminating them. This reduction in the number of interactions of a doctor with a technical laboratory results in the reduction of errors that can be made due to accidental damage or damage in transit and/or mutual misunderstanding between the dentist and dental technician. The patient can receive their ready a comfortable prosthesis is much faster, i.e. he did not have long to live without prostheses. A significant decrease in errors allows the doctor and the technician to serve a larger number of patients, which increases their income. In addition, the prosthesis made in accordance with the laws the AI with the invention, much stronger due to the metal base 10, surrounding the base of the dentition, and through reinforcing the grid 92, completely covering the base and surrounding the boundaries of the upper and lower dentures. Made in accordance with the invention prostheses have excellent characteristics by virtue of running in them pressed element 140.

The implementation of the invention leads to a striking improvement in the appearance of the dentures with the ability to set each artificial tooth in the desired position. Thus, the prosthesis becomes much more natural look and corresponds to the bite of the patient. The scallops around the edges of the prosthesis with the apron also produce a more natural looking denture.

Articulated support provide the ability to adapt them to a wide range of sizes and shapes to dental arches of the patient that provides accurate prostheses that have a natural look, even if arcs have abnormal size or shape or is abnormal bite.

Put the blocks containing one or more artificial teeth, complementary advantages described herein systems and methods provide a simple but robust mechanism for fixing teeth, which also speeds up the process of making dentures. Put the blocks can be used in the us with other types of artificial teeth, also described herein, for example with separate teeth attached to the base through the existing holes in it.

Described in the invention the upper and lower impression spoon is useful in cases where the prosthesis is damaged, lost or the patient is in need of dentures for the first time. The upper and lower impression spoons additionally simplify and accelerate the process of prostheses, and impression spoon, supplied with plastic reinforced mesh arch and/or skirt, contribute to a better fitting of the prosthesis.

All aspects of the invention can be used by dental-prosthetics, laboratory technicians. They are closely associated with traditional systems and methods that are currently used, and can be entered at any stage of use of the conventional manufacturing process of the prosthesis.

Throughout the description the aim was not to limit the invention to any one aspect or a specific set of features.
