Description

The utility model relates to medicine, namely to dentistry, and can be used for permanent splinting of teeth with generalized periodontitis of mild and moderate severity.

The most common method of splinting mobile teeth in generalized periodontitis in dentistry is the manufacture of adhesive structures from non-metallic reinforcement and light-curing composites. This method is carried out by excising the required amount of tissue of the patient's enamel, followed by filling the resulting bed with a fiberglass tourniquet and a fluid light-curing composite material (Zhuravlev V.A.Methods of fixing mobile teeth in the treatment of chronic generalized periodontitis / V.A. / Problems of dentistry. 2014. - No. 2. - S. 4-8). The main disadvantage of this method of splinting is the shorter duration of operation compared to traditional fixed structures, the impossibility of using it on teeth with a destroyed occlusal surface (IROPZ 20-50%), as well as the impossibility of restoring defects in the dentition, if any.

A milled dental splint was taken as a prototype of a utility model (Patent No. 2632755 C1 Russian Federation, IPC А61С 8/00 (2006.01) Milled dental splints: No. 2016121798: applied for 06/02/2016: publ. 09.10.2017 / S.D. Arutyunov, О O. Yanushevich, E.V. Ippolitov [and others]. - Bulletin No. 28. - 7 p.). This splint is designed for long-term immobilization of mobile teeth with the possibility of replacing dentition defects. A milled dental splint is made using CAD / CAM technology and is located on the lingual or palatal surface of all teeth, overlapping the clinical equators of the teeth by 2 mm, so that its lower border runs along the border of the marginal periodontium, individualized for the existing teeth by applying ceramic mass and dyes followed by glazing.

The disadvantages of this device are the complexity of the preparation of the surface of the teeth for the manufactured structure, as well as unsatisfactory fixation on the teeth, due to the absence of additional retention elements.

The technical result, which the creation of this useful model is aimed at, is to increase the efficiency of splinting the dentition in generalized periodontitis, to increase the reliability of fixing the manufactured structure on the teeth by creating an additional retention platform and fixing the manufactured structure to the occlusal surface of the teeth.

The essence of the proposed useful model lies in the fact that the dental splint for the treatment of generalized periodontitis is made monolithically of zirconium dioxide and is made by the CAD / CAM method for recognizing the optical impression of the patient's oral cavity, with the restoration of missing teeth, characterized in that the splint is made on the lateral teeth in in the form of inlays of the Overlay type with an occlusal surface thickness of 2 mm, and on the anterior teeth - in the form of full artificial crowns.

An enlarged image (opens in a separate window) a dental splint for the treatment of generalized periodontitis (Fig. 1) is a monolithic structure made of zirconium dioxide, which consists of Overlay-type inlays (Fig. 2) with an occlusal surface thickness of 2 mm on the chewing teeth (1 ) and a retention platform (4) with a depth of 1 mm and sides, with an individual angle of inclination of the surface (α), the choice of which occurs after preliminary parallelometry. (Fig. 3). In the anterior section, the splint represents full crowns (2) with a thickness of 0.5-1.5 mm. In the absence of teeth, the defects are replaced with artificial teeth (3).

A dental splint for the treatment of generalized periodontitis is made as follows.

1. Obtaining diagnostic impressions and casting of diagnostic models of the jaws;

2. Carrying out preliminary parallelometry and choosing the way of introducing the future structure;

3. Preparation of teeth in the lateral part of the dentition under overlays (5): preparation of the occlusal surface by 2 mm, creating a retention cavity 1 mm deep with sides, the angle of inclination of which corresponds to the route of insertion of the future structure; in the anterior part of the dentition, the teeth are prepared for full artificial crowns 0.5-1.5 mm thick with a circular shoulder (6) - Fig. 4.

4. Obtaining an optical impression;

5. Computer simulation of the shape of the future bus (Fig. 2).

6. Data transfer to the milling unit and milling of a dental splint made of zirconium dioxide.

7. Individualization of the occlusal and vestibular surfaces of the splint.

8. Fitting and fixing the splint in the mouth with dual-curing composite cement.

The proposed splint for the treatment of generalized periodontitis makes it possible to improve the quality of splinting of the dentition in generalized periodontitis, to increase the reliability of fixation of the manufactured structure on the teeth by creating an additional retention area and fixing the manufactured structure on the occlusal surface of the posterior teeth and making full crowns on the anterior teeth of the dentition.
