Description

The invention relates to the field of veterinary medicine and can be used in surgical dentistry to correct congenital or acquired malocclusion in dogs.

A certain order of teeth arrangement in dogs relative to each other allows the dentofacial system to function correctly, which consists in the most successful distribution of physical effort during mechanical processing of the feed and the formation of the food coma. In turn, improperly positioned teeth do not fully or completely do not participate in the process of biting and grinding the food, and also injure the mucous membrane of the gums or other teeth, which leads to under- or overload, causing changes in periodontal or erasing the crowns of antagonist teeth.

Various pathologies of occlusions in dogs are corrected with the help of a variety of orthodontic appliances and devices. Thus, the well-known orthodontic apparatus for correcting tooth dystopia and malocclusion in dogs (Patent RU No. 70119, published January 20, 2008) contains an active element, an orthodontic screw, a base element, orthodontic plastic and fixing elements, in which the fixing elements applied to the canines, are the main locking elements. Each main fixing element is made of a piece of orthodontic wire, from which a fixing loop is formed corresponding to the length of the rim of the tooth crown, a compressing loop with a diameter of 2-3 mm, formed by a single twist in the central part of the fixing loop, and fixing pair ends 3-5 mm long each . The fixing pair ends are made in the configuration of the main fixing element opposite to the location of the compression loop, in addition, the locking pair ends are placed in the thickness of the base element so that the compression loop when installing the orthodontic apparatus is installed in front of the oral cavity from the side of the lip. The length of the segment of the orthodontic wire, from which the main fixing element is made, is determined in total by the length of the fixing loop, by the length of the diameter of the compression loop and by the length of the fixing pair ends.

The disadvantages of the method include the following: the process of moving the teeth is stretched in time (2-2.5 months), while the long-term presence of the orthodontic apparatus in the oral cavity of animals contributes to the retention and accumulation of food residues in the recesses of the apparatus, traction springs and wire clasps, which leads to to the occurrence of inflammation at the points of contact and, therefore, to further partial or complete atrophy of the mucous membrane of the gums and periodontium, as well as the inability to correct the pathology of the bite in dogs having small sizes (height) of tooth crowns, since the working part of the Planas screw has no abutment surface due to the pyramidal shape of the latter. In addition, it is well known that bone tissue is a viscoelastic medium, and the developed orthodontic apparatus is offered in a combined design with the possibility of repeated installation or removal of the apparatus throughout the entire period of orthodontic intervention, which contributes to the partial or complete return of the tooth to its original position.

The technical task of the claimed invention is the creation of a technologically simple method for surgical correction of occlusion in dogs with obtaining a persistent clinical effect.

The technical result is to ensure the stability of the moved tooth after the preliminary correct osteotomy of bone tissue.

The technical problem is solved, and the technical result is achieved by conducting a preliminary osteotomy of the bone tissue of the crest of the alveolar process of the upper and lower jaws directly through the gum along the roots planned to move the teeth to a depth corresponding to the length of the roots of each of the teeth, followed by a dosed mechanical effect on each tooth by moving them alternately to the required positions, and fixing the moved teeth with a fluid photopolarizing material for a period of 3-4 weeks after yuschim its removal and polishing teeth displaced.

A preliminary osteotomy of the bone tissue of the crest of the alveolar process of the upper and lower jaws directly through the gum contributes to the creation of mechanical trauma, which is the trigger for the regeneration of bone tissue with the formation of primary bone callus, and then young bone tissue in the “normal” position. This makes it possible to obtain a persistent therapeutic and aesthetic effect in a short time (3-4 weeks) without the use of bulky, difficult to manufacture, addictive and constant hygiene of orthodontic appliances. Fixation of displaced teeth, in turn, in the “normal” position is carried out by a fluid flowing composite applied to the crown parts of the teeth according to the generally accepted method of adhesion of photopolarizing materials. The correction cycle is completed by the removal of the polarized material from the moved teeth and their polishing.

The claimed method is illustrated by the drawings.

In FIG. 1 shows the wrong position of the incisors in the dog, when the lower incisors extend beyond the upper, forming a “snack” with a violation of the correct formation of the dentition.

In FIG. 2 presents an osteotomy along the roots of the teeth in the upper jaw.

In FIG. 3 shows the implementation of a dosed mechanical action to move the incisor on the upper jaw.

In FIG. 4 shows a formed dental arch in the upper jaw.

In FIG. Figure 5 shows the fixation of displaced incisors on the upper jaw with a fluid photopolarizing material.

In FIG. 6 shows an osteotomy along the roots of the teeth in the lower jaw.

In FIG. 7 shows the fixation of displaced incisors on the lower jaw with a fluid photopolarizing material.

In FIG. 8 shows the position of the upper jaw incisors relative to the lower jaw incisors in the position “norm” - “scissors”.

In FIG. Figure 9 shows the incorrect position of the incisors in the dog when the lower incisors extend beyond the upper, forming a “snack” with a violation of the correct closing of the jaws.

In FIG. 10 shows the fixation of displaced incisors on the upper jaw with a fluid photopolarizing material.

In FIG. 11 shows the fixation of displaced incisors on the upper jaw with a fluid photopolarizing material.

In FIG. 12 shows the formed dental arch in the upper jaw after removing the photopolarizing material and polishing the teeth.

Example 1

The owner of the Pincher breed dog came to the veterinary clinic with a complaint about the improper position of the upper jaw incisors relative to the lower jaw incisors with the lower incisors extending beyond the upper ones with the formation of a “snack” and irregular dentition.

After a clinical and radiological examination, a decision was made on the surgical correction of dystopia of the maxilla and mandible incisors. At the time of the operation, the dog was 10 months old. Concomitant diseases were not noted. The mucous membrane is pale pink, without pathological changes. The alveolar ridge in the projection of the roots of the canines has a height sufficient for osteotomy and the formation of bone defects between the moved teeth. Clinical blood tests are within normal limits.

Treatment:

1) osteotomy along the roots of the teeth in the upper jaw;

2) the provision of a dosed mechanical effect on the incisors of the upper jaw (alternately) to move them to the required positions;

3) osteotomy along the roots of the teeth in the lower jaw;

4) the provision of a dosed mechanical effect on the incisors of the lower jaw (alternately) to move them to the required positions;

5) ensuring the stability of the moved incisors on the upper and lower jaws due to the fluid photopolarizing material.

The owner of the dog is familiar with the treatment plan, warned of possible complications.

Consent to surgery has been obtained.
