Known removable duclottni orthodontic devices (Guide to orthodontics. // Edited Pahorkatina. - M.: Medicine, 1999. - str-472), used in children for the treatment of distal occlusion.

In particular, it is known (ibid) activator Klammt containing sphenopalatine clasp, vestibular and lingual arc, the clasps on the upper side teeth and plastic lingual shields. Activator Klammt more comfortable to use, so often used in children.

Disadvantages:

- install activator Klammt in the mouth is widely open mouth and the extension of the lower jaw to neutral ratio of first permanent molars, which is virtually impossible with distal occlusion, leading to limited movements of the mandible;

- the use of the activator Klammt provides for holding the lower jaw in its extended position and closed teeth, that it is impossible to limit the movements of the lower jaw;

- speech function in the presence of activator Klammt in the oral cavity runs through tightly clenched teeth, which is reflected in the purity of sound;

- to obtain therapeutic effect of the activator Klammt you must use at least 20 hours per day that it is difficult to do as much as possible is Nemo because of the need for regular meals, communication with others;

in the treatment of distal occlusion is recommended to raise the lower jaw simultaneously not more than 3 mm, if necessary, repositioning the lower jaw more than 3 mm is made of two or more activator Klammt.

We used as a prototype activator of Andresen-Couple contains the maxillary and mandibular plastic plates, rigidly connected by a line joining the dental arches in the position of the constructive occlusion, in which the first permanent molars are in neutral ratio, the clasps on the upper side teeth and vestibular arc with two curved bends. If necessary, expansion of the dental arches activator saw in the midline and in the area of the sky set screw. Depending on the combination of distal occlusion Burin disocclusions or deep cutting occlusion occlusal surfaces of the posterior teeth or cutting edges of the front can be covered with plastic lining.

Disadvantages activator of Andresen-Couple:

- consistent fitting of the maxillary and mandibular parts of activator and set it in the mouth is only possible with widely open mouth, which is hard to do with limitation of movements of the mandible;

- avoid mouth breathing and speech in the presence of activat the RA in the mouth causing the child discomfort and rejection of the use of the activator in the daytime;

- use the activator mostly at night leads to a lengthening of the period of adaptation and treatment time.

SUBSTANCE: invention relates to medicine, namely to dentistry and is intended for correction of detected by early diagnostics temporomandibular joint (TMJ) dysfunctions. Anthropometry of face is carried out in order to determine displacement of lower jaw and measure the height of lower third part of face. Displacement of lower jaw is determined in sagittal, transversal and distal directions. In order to determine distal displacement of lower jaw Eshler-Bittner test is applied. To determine lateral displacements occlusography is carried out in habitual occlusion, results are obtained by computer program T-Scan. Orthopantomography is performed and value of joint spaces is determined. If secondary displacements of lower law in sagittal and/or transversal and/or distal directions are determined, joint spaces of various value on orthopantomogram and change of height of lower third part of face are present, dysfunction of TMJ is diagnosed. Lower jaw is installed in neutral state in central occlusion, mouthguard with bite sites for fixation of lower jaw in said position is made. Occlusography is repeated in central occlusion together with mouthguard, difference of initial and blocking contacts is determined and in case if contact is advanced, selective lapping is carried out. Conclusion about elimination of dysfunction is made on the basis of patient's subjective sensations, anthropometric data and holding of lower jaw in position without displacement in sagittal and transversal planes. Final correction of mouthguard is performed in central occlusion under control of OPTG with central position of TMJ head in glenoid fossa, after which mouthguard from silicon is replaced with plastic. Myotherapy is administered and orthodontic treatment and/or dental prosthetics is performed after adaptation in accordance with indications.

EFFECT: method makes it possible to detect and prevent TMJ diseases before development of expressed pathologic joint symptoms due to correction of TMJ dysfunction before clinical symptoms of joint pathology develop.
