FIELD: medicine.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 patients 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 correc
