Criticism of the prototype.

The method is characterized by low reliability and durability according to its functional purpose, the device is fast, but unreliable. This is because the role of the support elements of the two wires that are weaker, for example beam structure, and having a small contact area with the supporting teeth, breaks them. The method has another drawback - a "one-off" replacement is delayed by a few hours (see /3/) that will not withstand each patient.

The device prototype is characterized by low strength.

Technical result achieved - the purpose of the invention.

The aim of the invention is to increase the strength and reliability of the restoration of the dentition, achieved with minimal tissue injuries of the teeth, while the technical result is achieved in a sparing for p is e from the prototype used actions operations: inspection, the formation of cavities under the supporting elements can be mounted on the abutment teeth adhesive material, color matching, creating a wash space, adjustment of the bite, grinding, polishing and finishing illumination, and also made additional operations: addition is determined by the condition age security zones in the x-ray images of the abutment teeth, additionally measured the height of the coronal portion of the abutment teeth and only in case of exceeding the measured height of 6 mm formulate recommendations to the patient for the application of this method and choose the design of adhesive bridge prosthesis, then spend anesthesia and only then form a cavity under the supporting elements can be mounted on the abutment teeth adhesive material, in addition equalize the levels of the areas of the cavities relative to the working surface of this area of the dentition and provide parallelism sites formed cavities and the formation of cavities in both abutment teeth carried out taking into account age security zones, focusing on x-ray images, as well as provide for the sizes of the formed areas pomognato mounting on the abutment teeth adhesive material, additionally, make removal of the main and supporting casts of the upper and lower jaws and determine the occlusion, in addition additionally verify construction adhesive bridge prosthesis and forms of support elements can be mounted on the abutment teeth adhesive material, additionally produce adhesive bridge denture and beam construction with the support elements can be mounted on the abutment teeth adhesive material of this prosthesis is made with regard to the forms, dimensions and orientation of the abutment teeth and areas of the formed cavities in both abutment teeth, while the shape of the bending beam structure is chosen in accordance with the form of the replaced section of the dentition on the level of fixation, in addition in the manufacture of adhesive bridge prosthesis provide the orientation of the upper surface of the beam structure parallel to the approximated plane working surfaces of the abutment and the artificial teeth of this area of the dentition, and advanced level levels and provide parallel support elements can be mounted on the abutment teeth adhesive matureporn teeth, after the creation of the washing space is additionally carried out the fitting and the fitting adhesive bridge denture in the patient's mouth, additionally carry out a preliminary adjustment of the bite, and then fixed with adhesive bridge denture adhesive material is light-cured and after that adjust the bite, grind, Polish and perform finishing illumination.

In the claimed method of the 28 operations 8 operations taken from the prototype and 20 introduced additionally.

The essential features to achieve a technical result are:

1. compliance with the minimum necessary and sufficient from the practice of certain conditions exceeding 6 mm coronal part of both abutment teeth, if this condition is not fulfilled, then the recommendations for other ways to restore the dentition;

2. a necessary condition to obtain the strength and durability of the restored dentition is getting the sizes of the formed areas of the cavities in the abutment teeth equal to not less than 50% of the respective squares projection of the abutment teeth at the level of fixation of the supporting elements with vozmozhno results provide the action for the equalization of the levels of the platforms cavity in the abutment teeth relative to the working (upper) surface of this area of the dentition and to ensure their parallelism;

4. a necessary condition for the strength of the proposed technical solution in the manufacture of adhesive bridge denture is to ensure the orientation of the upper surface of the beam structure parallel to the approximated plane working surfaces of the abutment and the artificial teeth of this area of the dentition, the breach of which will lead to uneven load distribution and, generally, to a decrease in strength;

5. the requirement for the formation of cavities in both abutment teeth with age security zones and current control their relative position, focusing on x-ray images;

6. removing the main and supporting casts of the upper and lower jaw, the bite registration allows you to specify the design of adhesive bridge prosthesis, as well as the shape, size and orientation of its supporting elements can be mounted on the abutment teeth adhesive material;

7. necessary for the achievement of technical solutions used in the manufacture of adhesive bridge denture is the choice of shape beam structure with regard to shapes, sizes and orientation of the abutment teeth and areas of the cavities formed in the Noah curve of the replaced section of the dentition on the level of fixation, that is, at the level of the fastening.

Furthermore, in order to obtain the integral elements of a single, sturdy construction typed operations alignment levels and ensuring the parallelism of the supporting elements can be mounted on the abutment teeth adhesive material in accordance with the levels, dimensions and alignment of pads formed cavities in the respective abutment teeth.

Thus, the status of the age of security zones in the x-ray images of the abutment teeth, and the other factors identified when removing the main and supporting casts of the upper and lower jaw, the bite registration allows you to properly formulate recommendations to the patient and to convince him of the correctness of the choice of construction adhesive bridge prosthesis, which guarantees a conscious, correct, long-term operation of the proposed technical solution.

Listed essential characteristics are interrelated and are aimed at solving the problem of increasing the strength of the restoration of the dentition, as well as the strength of the device to achieve the goal of this method.

In the execution order of actions (operations) changes in Sonim material included additional operations, having a subordinate nature, that is implemented in conjunction with the formation of these cavities, they are transactions: the alignment of levels and parallelism sites formed cavities, accounting for the formation age of the security zones of the abutment teeth, taking x-ray images, and obtaining the sizes of the formed areas of the cavities is equal to at least 50% of the relevant areas of the abutment teeth at the level of form fields, i.e. at the level of fixation of the supporting elements can be mounted on the abutment teeth adhesive material. The requirement of the last operation greatly affects the strength of the whole structure, this value is 50% determined empirically, and is an essential characteristic of the proposed technical solution. This requirement is explained by the desire on the one hand to increase the bearing area, reducing the specific pressure, and on the other hand, to preserve the integrity of the tooth, making minimal injuries to the tissues of the teeth, taking into account the peculiarities of the abutment teeth, their status, orientation, age, security zones, and other informal settings, consistent with the experience and qualifications of the doctor.

Given vampirisim by and significant effect on the strength of the whole structure, when it is the failure to use a different method to restore the dentition. This distinctive feature of the proposed method is essential and necessary.

The essential features 3, 4 and 7 are integrated and achieve sverhsummarny effect, which consists in increasing the structural strength due to the exact consistency of shapes, sizes and orientation of the abutment teeth cavities with the support elements of the prosthesis that gives the optimal load distribution of the prosthesis inside and on the abutment teeth, and the characteristics of 3 - 7 take into account the spatial arrangement of the prosthesis, the abutment teeth, the teeth of the antagonists and other adjoining teeth, and the shape of the bending section of the dentition, which is important when biting and chewing food. These operations are taken into account and differences of degrees of freedom of the various teeth of this area of the dentition, without which the proposed technical solution will not possess the required strength.

In total comprehensive result participate and later added operations, such as pre-adjustment of the prosthesis about the bite, agreed adhesive bridge denture with teeth To takes into account peculiarities of dentition and chewing dynamics of the patient. In this part of the operations upon approval of the prosthesis to the tooth rows is outside of the oral cavity and to commit adhesive bridge denture that fits the action (operation) of a physician and has no effect on the abutment teeth, eliminates the appearance of tired patient's static tensions, the tension elements of the oral cavity, is not inherent in the normal conditions. This tension during long operations, such as the prototype, can be fixed by fixing an artificial tooth and will eventually destructive influence on the strength of the whole structure.

Comparison of the proposed method with known allows you to define new operations, new relationships, a new order of operations, the number, sequence and correlation of new operations are coordinated to achieve a common goal of reliability and durability created by using method of device - adhesive bridge prosthesis, as well as improve the reliability and strength of the restored dentition in the form of complex structures: adhesive bridge prosthesis and two abutment teeth, thus forming this complex design is consistent with subase to make a conclusion on the conformity of the proposed method the criterion of "novelty" and "significant differences". A new set of features and their interaction were included in the complex interaction and ensured the achievement of a new sverhsummarny quality - improving the reliability of not only the adhesive bridge prosthesis, but also the reliability of the restored area of the dentition. That is, the neighbors of such connections become stronger, as distributed load, decreased the number of degrees of freedom - the abutment teeth will not be filled up in the space now occupied by the prosthesis, teeth antagonists will cease to run from the gums, loosening of its neighbors, moreover, if at the time of application of this method the patient's tooth, standing against the missing tooth have already moved forward, after setting adhesive bridge prosthesis he will be forced to return to its rightful place, strengthening themselves and their neighbors. Compared to the same technical solutions this method is more efficient because less traumatic to the abutment teeth and allows the patient or a physician's recommendation to return the abutment teeth in the initial state, as introduced by way of changes in the abutment teeth the minimum required, in addition the method allows to demonstrate konechnogo of the prosthesis in the mouth of the patient. Such advantages of the proposed technical solution can greatly affect the patient's desire for its use.

In the device, this goal is achieved as follows.

Device adhesive bridge prosthesis is intended for the implementation of this method contains an artificial tooth, which is connected with the supporting elements can be mounted on the abutment teeth adhesive material, while the support elements can be mounted on the abutment teeth adhesive materials are protruding from the artificial tooth ends of the beam structure, the middle part which is fixed inside an artificial tooth so that the speakers on both sides of the ends of the beam structure are located on a line corresponding to the form of the replaced section of the dentition at the level of fixation, in this form, the size and orientation of the support elements can be mounted on the abutment teeth adhesive material correspond to the surfaces of the pads formed cavities in the respective abutment teeth, and beam design is the supporting frame of the artificial tooth, the upper surface of the beam structure parallel approximated plane on the abutment teeth adhesive material attached to the neighboring teeth in a specially prepared cavities, corresponding in shape, size and orientation. The depth of the cavity on each abutment tooth is made so as not to damage the pulp and ensure it is securely fastened and must be completely covered by the adhesive material.

Comparable analysis with analogue and prototype shows that the device is distinguished by the presence of a new element - beam design, which is the supporting structure of the artificial tooth, and protruding from the body of the artificial tooth of its ends are support elements can be mounted on the abutment teeth adhesive material. This has changed the design of the connection elements by placing the middle part of the beam structure inside an artificial tooth so that its protruding ends were located along the line of the area of the projection of the dental arch, approximated to the depth of the mounting beam structure relative to the surface of the artificial tooth. While the major surface of the beam structure is recognized to reduce the specific surface load on the artificial tooth and ensure its uniformity. While the supporting elements can be mounted on the abutment teeth adhesive material to form square, matched with a set of features in the form of an artificial tooth, beam design, the middle of which is a bearing construction, and the protruding ends of the supporting elements can be mounted on the abutment teeth adhesive material, and a new relationship, expressed in the appropriate orientation of the given beam structure and its ends - supporting elements can be mounted on the abutment teeth adhesive material, correspond to the optimal distribution of the total load of the claimed device on a specially prepared cavity (cavity mounting) on the abutment teeth, ensure interoperability and ensure the total effect of the relevant objectives of the invention. When this beam design is the supporting frame of the artificial tooth, and the upper surface of the beam structure parallel to the approximated plane working on the chewing surface of the artificial tooth in the device, and in the way the last sign has an extended meaning in the form of the upper surface of the beam structure parallel to the approximated plane working surfaces of the abutment and the artificial teeth of this area of the dentition, which became possible with the new elements that were not included in the description in the aqueous denture is a complete technical solution, which can be produced taking into account the individual characteristics of the patient, and in mass quantity in advance, for example, in the form of ready-made templates adhesive bridge dentures for all types of teeth and set a specific patient after studying the features of the restoration site of the dentition, modeling, planning, pre-treatment cavity and the subsequent preparation of the cavity, fixing using adhesive materials, for example, "Primor Bond" 2,0; 2,1 /3, 4/ or XR "Herculate" /4/ with polymerization, and fitting: the antagonist, neighbors and the gums, as well as the creation of the washing space, color matching, grinding the contact surfaces and polishing. This confirms the feasibility and practical significance of the claimed device.

Simplicity, reliability devices provide high strength and durability of both prosthesis and the construction as a whole, consisting of two abutment teeth and device adhesive bridge prosthesis. The location of the middle part of the beam structure inside an artificial tooth, and its ends in the respective cavities of the abutment teeth and is completely covered with the adhesive material ensuring that the group meets the criterion of "novelty."

A comparison of the proposed device with other technical solutions shows that an artificial tooth, an adhesive material and beam construction, for example a rectangular beam, is widely known. However, their connection in this respect and in accordance shapes, sizes and orientation of the support elements can be mounted on the abutment teeth adhesive material, shape, size and orientation of the squares of the areas of the cavities in the abutment teeth receiving device adhesive bridge prosthesis has high strength. This allows to conclude that the technical solutions according to the criterion of "significant differences".

This takes into account the features of the dentition (abutment teeth, antagonists, gum condition, the height of the crown part, state age security zones, particularly previous surgical interventions). Analysis of the claimed device, intended for implementing the method confirms that the design components are coordinated with each other, stronger and more reliable compared to the prototype. Device adhesive bridge prosthesis is enough to achieve the goal, while the restored dentition, consisting of this prosthesis and two abutment teeth, in General, create a single strong construction. Implementation method: a comprehensive analysis of the dentition, planning, fabrication, fitting and setting of the adhesive bridge dental FR the efficiency of use of dental equipment. The doctor, the dentist puts some operations specialists, allied health professionals, which also increases the efficiency of the dental office and the institution as a whole. You can procure various types of components such devices corresponding to the common defects of dentition, which significantly reduces the total time and cost of prosthetics. Simplicity, reliability devices provide high strength and durability as this prosthesis, and the construction as a whole, consisting of two abutment teeth and device adhesive bridge prosthesis. The location of the middle part of the beam structure inside an artificial tooth, and its ends in the respective cavities of the abutment teeth and is completely covered with the adhesive material ensure device compliance aesthetic and durability requirements.

A comparison of the proposed device with other technical solutions shows that an artificial tooth, an adhesive material and beam construction, for example a rectangular beam, is widely known. However, their connection in this respect and in accordance parameters: shape, size and orientation of the support elements can be mounted on oporn the received device adhesive bridge prosthesis has high strength.

Compared to the same technical solutions this method is more efficient because less traumatic to the abutment teeth and allows the patient or the doctor's recommendations eventually return the abutment teeth in the initial state, as introduced by way of changes in the abutment teeth the minimum required, in addition, the method allows us to demonstrate the final quality until the completion of all actions, that is, until the final fixing adhesive bridge denture in the patient's mouth.
