Device for the treatment of habitual luxation and subluxation of the mandible

 

(57) Abstract:

The invention relates to prosthetic dentistry and can be used for the treatment of habitual luxation and subluxation of the mandible. The device consists of a removable subendemic trays, fitted on the upper jaw in the area of 6 teeth in the anterior mid-line projections and corresponding recesses on the lower jaw. Directly behind the tuberosity of the maxilla performed thickening to limit the opening of the mouth. The technical result is to have a reliable treatment effect, reduction of terms of treatment and relapse. 4 Il.

The present invention relates to medicine, namely to prosthodontics.

According to who, the prevalence of habitual luxation and subluxation of the mandible is from 27 to 39% of dental patients. In this regard remains the undoubted problem of the treatment of this disease.

Known devices Burgansky C. I. (author. dis. on saisc. Kida. the honey. Sciences. - Kiev, 1968, 19 S.), Pomerantseva-Urban (Petrosov Y. A. et al. - Diseases of the temporomandibular joint. - Krasnodar, 1996, S. 184-188), Schroeder (Gavrilov, I. I., A. Shcherbakov S. - Fitting Stomatolog ivanie mouth with peloton, resting in the branch of the lower jaw.

Disadvantages: pelota are traumatic to the mucosa, Kappa bad is fixed on the upper jaw, not holding the lower jaw in the position of Central occlusion, in addition, they contribute to excursions articular head left and right, which leads to further relaxation of the muscular-articular apparatus TMJ.

For the prototype, we made the device for the treatment of habitual luxation and subluxation Sound, K. S. (khvatova Century A. diseases of the temporomandibular joint. - M.: Medicine, 1982, S. 85-87). The main element of the device is Kappa. The Kappa impose on the upper jaw. On the side surface of the mouthguard has pelot, rests on the branch of the lower jaw, limiting mouth opening.

The disadvantages of the prototype coincide with the disadvantages of the above-described counterparts. In addition, pelota create a functional and aesthetic discomfort, causing constant pressure on the chewing muscle, leading to asymmetry of the face.

Tasks:

- improving the efficiency of orthopedic treatment of habitual luxation and subluxation of the mandible;

- providing restrictions otkryvanii the branches of the lower jaw during treatment;

- eliminate trips articular head in the transverse motions;

- reduction of treatment time;

- reducing the number of relapses.

The essence of the invention is the provision of mouthguards on the upper jaw in the area of 6 teeth in the anterior mid-line of the face protrusions and corresponding recesses on the lower jaw, and directly behind the tuberosity of the maxilla bulges to limit the opening of the mouth. The protrusions and recesses can be in various ways, including V-shaped, lunoobraznye, cylindrical. However, according to the applicants, more effective option are protrusions and recesses along the contours of the shapes and sizes of natural teeth. The device illustrated in the drawings (Fig. 1, 2, 3, 4), it is shown in a vertical incision in the midline of the face and on which is shown:

1 - Kappa on the upper jaw;

2 - Kappa on the lower jaw;

3 - the tabs on the Kappa upper jaw;

4 - holes on the Kappa lower jaw;

5 - thickening of the Kappa.

The device is used as follows.

Pre-made individual subnamespace mouthguards on the upper jaw 1, the lower jaw 2 with smooth-on models the projections 3 and the corresponding recesses 4, and abroad the upper jaw mouthguard creates thickening 5 preventing a wide mouth opening.

The proposed device has been tested in a clinical on 56 patients. The positive aspect was the use of splints in the treatment of dislocations and subluxations of the mandible with any number of missing teeth (partial or full), any topography: included (Fig. 1, 2) or distal limited defects (Fig. 3, 4).

The use of the device eliminates the trauma, not to disturb the aesthetics, securely fix the lower jaw against lateral (transverse) movement, reduce treatment time by 30-40%.

Device for the treatment of habitual luxation and subluxation of the mandible containing dental splints for the upper and lower jaws, characterized in that in the area of projection of the six teeth in the anterior mid-line of the person Kappa has the tabs on the upper jaw and the corresponding recesses on the lower jaw, and directly behind the tuberosity of the maxilla Kappa is thickening to limit the opening of the mouth.

FIELD: medical engineering.

SUBSTANCE: method involves producing an opening of diameter reaching 2 mm with diamond or hard alloy bore in adhesive cover after preparing abutment tooth and prosthesis or widening already available perforation also to diameter of 2 mm. The prosthesis is set on the abutment tooth and place is marked for creating and directing pin-canal in the area of cutting one-third of the frontal abutment tooth or in the lateral abutment tooth equator area. The pin-canal direction is to correspond to path for introducing the prosthesis. The pin is screwed-in with screwdriver and holder to a depth of about 2 mm into dentin. The prosthesis is set on the abutment for making control. The pin is filed-off to adhesive cover layer after having fixed the prosthesis on composition cement.

EFFECT: prolonged service life; high functional value.

SUBSTANCE: method involves taking anatomical imprint from jaw under prosthetic repair, casting supergypsum model for carrying out parallelometric studies, model duplication, modeling future clasp carcass skeleton from wax, enclosing the wax model into cell filled with gypsum, evaporating wax and filling the arisen cavity with polymer. The clasp carcass model is reproduced as metal one from polymer model for all models taken in production. Polymer for manufacturing clasp carcass model is reactive composition hardening at room temperature and composed of two ingredients taken in 2:1 proportion by weight. The first ingredient portion is based on polymethyl methacrylate, and the second one is polymethyl methacrylate with dimethylaniline added in the amount of 1-2% by mass.

EFFECT: significantly accelerated carcass manufacturing process; high accuracy in reproducing sizes; improved connection of locks and telescopic crowns to polymer carcass; low production costs.

SUBSTANCE: device has vestibular and oral parts connected to each other with crosspieces manufactured from orthodontic wire placed in interdental spaces by producing jaw imprints. Working and auxiliary models are molded. To place treating bandage, general clinical equator of all teeth included into the splint is to be determined on working model using parallelometer. Then, space between the clinical equator line and gingiva and a gingiva part 7-8 mm remote from gingival papillae are covered with dental wax layer of thickness equal to or less than 1.5 mm. Next to it, duplicate model is produced for manufacturing the splint having recess equal to wax layer thickness 1.5 mm. Changing wax for transparent plastic, filing and polishing the splint is carried out by applying method of common use.

EFFECT: enhanced effectiveness of treatment.
