RU64050U1 - DEVICE FOR TREATING TRANSVERSAL SHIFTS OF THE LOWER JAW - Google Patents

Abstract

The utility model relates to medicine, namely to orthopedic dentistry and can be used to correct transversal shifts of the lower jaw, treat dysfunction of the temporomandibular joints and chewing muscles. We have for the first time proposed an apparatus that allows continuous predetermined movements of the lower jaw in the transverse plane with the possibility of adjusting the movements of the lower jaw during treatment without removing the design from the abutment teeth, containing crowns on the lateral teeth of the upper jaw, a guide assembly, characterized in that it consists of plastic guide surface sliding to the lower teeth of the lower jaw and mounted on a metal plate soldered parallel to the vestibular surface of the cornea knock.

Description

The device relates to medicine, namely to orthopedic dentistry and can be used to correct transversal shifts of the lower jaw, treat dysfunction of the temporomandibular joints and chewing muscles.

A device for treating a distal bite is known. The device consists of fixed crowns on the upper and lower lateral teeth and a node for holding the lower jaw in a corrective position, made in the form of two vestibular guides with open sliding surfaces and mounted on the crowns of the lateral teeth (copyright certificate 1438759).

The essence of this design is two vestibular guides with open sliding surfaces, an expanded base at the places of soldering to the crowns and distal platforms at the free ends. The device provides continuous predetermined movements of the lower jaw in the sagittal plane and prevents its displacement distally.

The disadvantages of this design include:

1 - the inability to adjust lateral movements and the position of the lower jaw in the transverse plane, which prevents the correction of the pathology of the dentition, masticatory muscles and temporomandibular joints in the transverse plane;

2 - the inability to adjust and change the direction of movement of the lower jaw in the transverse plane during treatment without removing the structure from the abutment teeth.

We have for the first time proposed an apparatus that allows for continuous predetermined movements of the lower jaw in a transverse plane with

the ability to adjust the movements of the lower jaw during treatment without removing the structure from the abutment teeth, containing a crown 1 on the lateral teeth of the upper jaw, a guide assembly, characterized in that it is made in the form of a plastic guide 2 mounted on a metal plate 3 with retention points 4 for holding plastic, soldered parallel to the vestibular surface of the crowns and the sliding surface facing the lateral teeth of the lower jaw.

Figure 1 shows the apparatus for the treatment of transversal shifts of the lower jaw, where:

1 - fixed crowns,

2 - metal plate

3 - retention points,

4 - plastic guide.

The method of manufacturing the apparatus:

1) Permanent metal crowns 1 are made on the lateral teeth of the upper jaw.

2) Crowns fit in the patient's mouth and take impressions with crowns. Cast models.

3) Using the front arc, the central occlusion is fixed and the received registration is transferred to the articulator. Install models in the articulator.

4) The adjacent crowns are soldered and the metal plate 2 with retention points 3 are soldered parallel to their vestibular surface.

5) In the articulator, taking into account the individual movements of the lower jaw on a metal plate, a guide 4 is modeled from wax with a sliding surface facing the lower teeth of the lower jaw.

6) Replace wax with plastic.

7) Fitting the device in the patient's mouth.

8) The final finish of the structure.

9) Fixation of crowns on cement.

The mechanism of action of the apparatus for treating transversal shifts of the lower jaw is as follows: when opening and closing the mouth, the lateral teeth of the lower jaw slide at a given angle along the sliding surface of the plastic guide, which helps to normalize the movements and position of the lower jaw, temporomandibular joints and function of the masticatory muscles. If necessary, it is possible to correct the movements of the lower jaw in the transverse plane during treatment by layering or grinding the plastic on the plastic guide.

The proposed apparatus is designed to eliminate transversal shifts of the lower jaw, treatment of dysfunction of the temporomandibular joints and chewing muscles, which will increase the effectiveness of the treatment of patients with this pathology. The apparatus for the treatment of transversal shifts of the lower jaw allows for continuous predetermined movements of the lower jaw in the transversal plane without violating the chewing function and with the possibility of adjusting the movements of the lower jaw in the transverse plane during treatment by layering or grinding the plastic on a plastic guide. The use of the apparatus for the treatment of transversal shifts of the lower jaw can reduce the treatment time for transversal anomalies and malocclusions, dysfunction of the temporomandibular joints and chewing muscles.

Claims (1)

Apparatus for the treatment of transversal shifts of the lower jaw, consisting of crowns and a node guiding the movements of the lower jaw, characterized in that the node guiding the movements of the lower jaw is made in the form of a plastic guide rigidly connected to a metal plate reinforced parallel to the vestibular surface of the crowns.
