The invention relates to dentistry and can be used to correct dental anomalies associated with the presence of gaps between the front teeth of the lower jaw. The presence of gaps between teeth violates the patient's appearance, leads to disruption of speech.

As follows from the prior art (Prosthetic dentistry, V.n.trezubov, Aserbekov, Lmini, FOLIO, St. Petersburg, 2002) with the right ratio of dentition Treme between the teeth usually do not resolve and only in some cases, resorted to the prosthesis. In the same source of information indicated on the application to resolve the diastema removable laminar devices with springs, vestibular arcs or arc removable wire devices, crowns levers, hooks, springs, rubber traction. Essence of well-known techniques of removing diastema using these tools is a forced change of position of the Central incisors in relation to the midline. Among the significant disadvantages of the known methods include trauma due to the obstruction of the connective tissues of the teeth as they move, the significant duration, as well as relapse anomalies. After removal of the device, the teeth can return to their previous position. Therefore, to secure the correct amount of IU who do teeth additionally use retainers. Patients of older age, who do not wish to undergo long-term treatment, diastema is fixed prosthetics.

Known methods of prosthetics in the elimination of the diastema and three, as a rule, require laboratory stages, dental laboratory, traumatic due to the need of excessive dissection of the healthy tooth crowns, lengthy and costly.

It should be noted that in the prior art have not found information about how to comprehensive elimination of these forms of anomalies.

The aim of the invention is to develop a way of removing the diastemas and three from the anterior teeth of the lower jaw.

Features of the tools and techniques used for implementing the inventive method allows to simplify the procedure of eliminating gaps between the front teeth, to reduce the duration of the procedure and trauma, to increase the strength of the restored tooth, completely eliminate the Breasts anomalies.

The advantages of the proposed method make it attractive for patients of any age.

In clinical practice have to deal with combined defects, in particular with the presence of gaps in front teeth and additionally abrasion of hard tissues of teeth of the lower jaw. In financial p is Tata abrasion occurs reducing the height of the crowns of the anterior teeth, then there is a violation of their anatomical form.

In the prior art it is known that the abrasion of the teeth of the lower jaw in order to restore their function and appearance, as well as warnings of the consequences of further abrasion resort to prosthetics.

The inventive method allows to solve the problem of eliminating the diastema and three anterior teeth of the lower jaw as in the normal ratio of dentition, and in the case of abrasion of the teeth of the lower jaw with providing the same technical result. However, depending on the clinical situation using composite materials, reinforced with metal-plated grid, exercise capacity approximal surfaces of the crowns of each of the anterior teeth adjacent to the defect, the value of half of the gap between the teeth and restore the cutting edge, or carry capacity of approximal surfaces of the crowns of each of the anterior teeth on the value of half of the gap between the teeth and restore the cutting edge of the crown of each front tooth considering the magnitude of the loss of hard tissue as a result of abrasion of teeth.

Technical result achieved when implementing the inventive method, is to improve the aesthetics and functional properties of the anterior teeth of the lower jaw, atractive avannah simple method, along with providing increased strength and durability of the restoration.

The technical result due to the elimination of gaps between teeth, and if necessary, at the same time and compensation for loss of regeneration of hard tissue cutting edges of the anterior teeth with composite materials. At the same time to increase the strength and durability of the restoration of the coronal part of the anterior teeth and fate, formed using the composite material, optionally reinforced with metal-plated grid.

Using the rectangular metal plated mesh to reinforce the cutting edge, the grooves formed on the approximal surfaces of the teeth and oral tooth surface, i.e. the parts of the crown are the most vulnerable to the negative impact of functional loads. Since the width of the grid exceeds the media-distal dimension of the tooth crown to the spacing between the teeth, net, recorded in the grooves of the crown, stands for the boundary of each of approximal tooth surfaces at a value not greater than half the magnitude of the gap between the teeth. Due to these protruding parts of the grid, from which previously removed cross wires, and released the longitudinal wire closer in the cervical area of the tooth, reinforced composite materials, with which astronauts the diastema and Treme teeth. The use of open wire mesh allows to generate a restored crowns of the anterior teeth in accordance with the form of approximal tooth surfaces.

When implementing the proposed method takes into account the features of the distribution of functional loads acting on the crown part of the anterior teeth. Because the cutters during the act of mastication are bending, additional reinforcement of oral tooth surface greatly increases the strength and durability of the functioning of restored anterior teeth.

A reinforcing grid properties allow you to:

to increase the area of contact with the composite material;

to reduce the shrinkage of the composite material and to improve the marginal seal material to the tooth hard tissues;

to reduce the tension (stress)occurring during polymerization;

to ensure the prevention of possible complications chips and bruised coronal part of the tooth;

to increase the durability of the reconstruction;

to ensure high aesthetic quality;

to reduce the cost of reconstruction.

to reduce the duration of reconstruction

The essence of the invention.

In the case of the normal ratio of dentition proceed directly to the elimination of three and diastemas according to the claimed method.

In the case of attrition lower teeth is her jaw elimination of three and anterior teeth diastema claimed process is carried out after raising the bite chewing teeth in accordance with known methods.

Further mechanically clean the surface of the reconstructed anterior teeth toothbrushes using toothpastes. Determine the appropriate color of the teeth on the standard scale VITA. Isolate the oral cavity from the liquid medium. Perform the retraction of the gums. The crowns of the anterior teeth, between which there are gaps (diastema and Treme), dissect. Along the cutting edge to form a groove, rolling in vertical grooves formed in the direction from the cutting edges to the level of the cervical region on the approximal surfaces of each restored tooth. In the preparation of the formed U-shaped groove, covering the approximal surface and cutting edge of the crown of each of the anterior teeth. On the oral surface of the tooth to form a support platform, which bring in a groove made along the cutting edge. Dissection of the oral surface is carried out on 1/3 of its length, away from the medial and distal edges of the crowns 1-2 mm. Dissection is performed with the consideration of the anatomical form prepariruetsya surfaces.

In the grooves and on the frame in the subsequent fix the mesh, which is pre-formed in accordance with the sizes of the surfaces of the fixation. For this purpose, the metal plated mesh of rectangular shape. The dimensions of the rectangular behold the key chosen, taking into account the height of the crown restored tooth and the size of the gap between the teeth so to one of its sides was no more than a specified height, and the other side is not more than the sum of the widths of the crown in the media-distal direction and magnitude of the gap.

Formed reinforcing metal plated mesh consists of a General part, fixed in the groove along the cutting edge, which becomes separated from the other part, fixed in the slots on the approximal surfaces, and an intermediate part fixed on the oral surface of the tooth. Part of the mesh, fixed in the grooves of approximal surfaces, additionally remove the cross wires, freeing longitudinal wire mesh, but not more than the length of the vertical grooves approximal surfaces. The intermediate portion of the grid form in accordance with the size and shape of foothold on the oral surface. With mesh fixation intermediate part should be resting on the ledge of a platform at a distance of 1/3 the length of the oral surface of the tooth. Carry out the fitting and correction of the shape and size of the formed reinforcing metal plated mesh. Fixed mesh side approximal surfaces must be in an amount equal to half the value of the gap between the teeth. The total part of the mesh, fixed in a groove along the cutting edge should be at least 1 mm n the same level of the cutting edge to form a transparent restored the cutting edge. In the case of abrasion of the anterior teeth, the position of the General part of the grid in relation to the level of the cutting edge is determined by taking into account the attrition of his hard tissues. In this case the part of the mesh, fixed in the groove grinded along the cutting edge, can be positioned below its level, and projecting above the level grinded cutting edge. With the aim of forming a transparent cutting edge in the case of the abrasion condition of the location of the fixed grid of at least 1 mm below the level of the cutting edge of the tooth must be fulfilled in relation to the cutting edge of a tooth restored with the height of the crown. The mesh has no voltage to be formed in the grooves and on the frame.

After fitting and correction grid is removed, cover with adhesive, lightly blow air for uniform distribution of the adhesive and the preservation of cells through and will polimerizuet standard method.

U-shaped groove along the cutting edge and on approximal surfaces) and the support pad is subjected to acid etching. Then thoroughly rinse with water, dried, apply the adhesive and polimerizuet standard method.

After filling the U-shaped groove and the supporting surface flowable composite set of reinforcing mesh. Available wire grid boxes fixed in the grooves on approximativement, closer to each other in the cervical area of the tooth, forming the contours of the coronal part of the restored tooth in accordance with the form of approximal surfaces. Conduct directed polymerization.

Using composite materials conduct the final formation of the tooth crown. Eliminate Treme and diastema, replacing the teeth of the composite material, and restore the cutting edge. In the case grinded cutting edge of using composite material additionally recover lost hard tissue cutting edge of the tooth, restoring the height of the crown in accordance with its anatomical height. Conduct directed polymerization.

The aesthetic effect is achieved after processing standard polishing disks of different thickness and grain size of the abrasive. Approximal surfaces of the strips. Correction of the cutting edges are under the control of occlusal paper finish using burs, disks. Produce final adviceline with palatal and vestibular surfaces.

Thus, the claimed method allows to eliminate Treme and diastema as in the case of the normal ratio of dentition, and the abrasion of the teeth of the lower jaw, can improve the aesthetics and to restore the functional properties of the restored teeth, to increase durable to u is ity restoration.
