RU211097U1 - Kappa for repositioning the lower jaw - Google Patents

Abstract

The utility model relates to dentistry, in particular to dissociating-repositioning occlusive mouth guards used to expand the articular space for decompression of the joint elements and create conditions for the reposition of the articular disc. The purpose of the utility model is to create an individual kappa for repositioning the lower jaw, which provides effective reposition of the lower jaw and tongue muscles, as well as relaxation of the lateral pterygoid muscles in the process of treating TMJ dysfunctions. The technical result is achieved by the fact that the proposed mouthguard in the front part has a guide for the tongue, the upper edge of which reaches the incisive papilla of the upper jaw, while there is no contact in the region of the anterior group of teeth of the upper jaw and the mouthguard, and the gap created between the front part of the mouthguard and the front group upper teeth is at least 70 microns. Thus, due to the guide for the tongue formed in the described way, in the process of wearing the mouthguard, a restructuring of the muscles of the tongue and the lateral pterygoid muscle, which are jointly involved in the work of the muscular system of the maxillofacial region, is achieved. 1 ill.

Description

The utility model relates to dentistry and is intended for the treatment of dysfunctions of the temporomandibular joint (TMJ), myofunctional disorders, increased tooth wear, as well as for the prevention of the development of arthrosis of the temporomandibular joints.

For the reposition of the lower jaw, in the field of dentistry, therapeutic and diagnostic mouthguards have been used, such mouthguards have an occlusal surface in the lateral areas, and the therapeutic effect is achieved due to the specified position of the lower jaw relative to the upper.

Disclosed in the present description kappa for repositioning the lower jaw refers to dissociating-repositioning occlusal kappa used to expand the articular space for decompression of the joint elements and create conditions for repositioning the articular disc.

From the prior art, various solutions of mouthguards for repositioning the position of the lower jaw are known (RU 142359 U1 (A61C 13/00, 06/27/2014), RU 83699 U1 (A61C 7/36, 06/20/2009), RU 197113 U1, (A61C 7/00 , 04/01/2020).

A common disadvantage of these solutions is the lack of individual modeling of the occlusal surface of the kappa in the ideal physiological resting position of the lower jaw relative to the upper jaw, the lack of the possibility of effective reposition of the tongue and restructuring of its muscles.

The purpose of the utility model is to create an individual kappa for repositioning the lower jaw, which provides effective reposition of the lower jaw and tongue muscles, as well as relaxation of the lateral pterygoid muscles in the process of treating TMJ dysfunctions.

An additional advantage of the utility model is the possibility of starting orthodontic treatment at the same time as wearing a mouthguard.

The claimed technical result is achieved by the fact that the proposed mouthguard in the front part has a guide for the tongue, the upper edge of which reaches the incisive papilla of the upper jaw, while there is no contact in the area of the anterior group of teeth of the upper jaw and the mouthguard, and the gap created between the front part of the mouthguard and the front group of upper teeth is at least 70 microns. Thus, due to the guide for the tongue formed in the described way, in the process of wearing the mouthguard, a restructuring of the muscles of the tongue and the lateral pterygoid muscle, which are jointly involved in the work of the muscular system of the maxillofacial region, is achieved.

The claimed invention is illustrated by drawings:

in fig. 1 shows a general view of the mouthguard in accordance with the group of inventions, installed on the dentition of the lower jaw;

in fig. 2 shows a section in the frontal plane of the lateral section of the lower jaw with a mouthguard installed;

in fig. 3 shows the maxillofacial apparatus in lateral projection with a mouthguard installed.

The figures are provided with the following symbols

1 - lower jaw;

2 - upper jaw;

3 - basis;

4 - occlusal surface of the chewing group of teeth of the lower jaw;

5 - occlusal surface of the kappa;

6 - cutting edges of the anterior group of teeth;

7 - crown part of the dentition;

8 - lingual side of the lower jaw;

9 - vestibular (buccal) surface of the teeth;

10 - guide for the tongue;

11 - clasp.

The kappa for repositioning the lower jaw, in accordance with the utility model, contains a base 3 made of plastic, with pits on the occlusal surface of the kappa, corresponding to the chewing surfaces of the lateral group of teeth of the upper jaw, while the basis 3 covers the entire dentition of the lower jaw 1 in the following boundaries: from the lingual side of the lower jaw 8 (1-1.5) mm above the bottom of the oral cavity, bypassing the mucous cords and frenulum of the tongue, overlapping the coronal part of the teeth 7, the occlusal surface of the lower jaw 4, the cutting edges of the anterior group of teeth 6, while not overlapping the vestibular surface of the teeth 9, in addition, from the lingual side, the base 3 includes a guide for the tongue 10, the position and height of the upper edge of which are determined by the position of the incisive papilla, so that a gap of at least 70 microns is structurally provided between the base and the anterior group of teeth of the upper jaw.

The basis is held on the lower jaw due to anatomical retention, as well as with the help of two or more clasps 11.

An example of the implementation of the utility model (practical implementation)

In a particular case of the implementation of the utility model, the basis is held on the lower jaw with the help of button clasps, which are fixed in the undercuts of the interdental spaces of the lateral group of the teeth of the lower jaw.

In a particular case of the implementation of the utility model, the kappa base is made of transparent hot polymerization acrylic plastic.

In a particular case of the implementation of the utility model, a kappa for repositioning the lower jaw is made as follows:

take impressions of the lower and upper jaws;

carry out relaxation of the muscles of the head and neck using the method of transcutaneous electrical nerve stimulation;

determine the height of the lower third of the face, fixing the position of the lower jaw using a silicone register on the resulting trajectory;

a kappa is made using the obtained register, including the creation of models from plaster according to the impressions of the upper and lower jaws;

the upper model is plastered into the articulator using the facial bow or Shestopalov's table and the lower model using the obtained register;

a mouthguard is modeled from base wax on a working model of the lower jaw with preliminary drawing of the borders of the mouthguard and installation of two to four button clasps in the area of the lateral group of teeth;

replace wax with hot polymerization acrylic plastic;

after completion of the polymerization process, they process, grind, polish the kappa for further fitting of the kappa in the patient's mouth.

The border of the kappa on the working model is formed as follows: on the lingual side - 1-1.5 mm above the bottom of the oral cavity, bypassing all the mucous cords and frenulums, capturing the occlusal surface without overlapping the vestibular surface of the teeth, thus the basis of the kappa covers: chewing surface and cutting edges of the teeth of the lower jaw. The occlusal surface of the kappa in the lateral area is modeled in accordance with the chewing surface of the lateral teeth of the upper jaw. In the anterior section, a guide for the tongue is formed in such a way that its lingual surface approaches the incisive papilla of the upper jaw.

In a particular case, the implementation of the utility model, the treatment process using a kappa for repositioning the lower jaw is carried out as follows:

After successful fitting of the mouthguard in the patient's mouth, the patient is given recommendations on how to use the mouthguard, depending on the type and characteristics of the pathology. Next, control examinations of the patient are carried out with a certain frequency. With positive dynamics and no complaints, they proceed to the next stage - reconstruction of the oral cavity using orthodontic, orthopedic, therapeutic and combined methods of dental treatment.
