METHODS FOR DETERMINING THE POSITION OF MOTOR AND TRIGGER POINTS OF THE CHEWING MUSCLES OF DYSFUNCTION OF THE TMJ

Various publications, from 40 to 60% of the population have various diseases of the temporomandibular joint (TMJ), most of them - functional disorders. A special place in the violation of the temporomandibular joint belongs to the increase in the tone of the masticatory muscles and their dysfunction. It is impossible not to take into account in the pathogenesis of diseases of the temporo-mandibular joint and the role of disorders of occlusal relationships. The correct diagnostic process is hindered by the lack of a single classification of joint diseases. Literature data and clinical observations indicate that in the etiology and pathogenesis of diseases of the temporomandibular joint, the above reasons are important. It is necessary to emphasize the interdependence of all these etiological factors. Back in 1996, Yu. Petrosov proposed a working classification, according to which functional disorders and diseases of the temporomandibular joint are divided into 5 groups. One of the groups were dysfunctional conditions of the joint: - neuromuscular dysfunctional syndrome; - occlusal-articulatory syndrome; - habitual dislocations and subdislocations of the lower jaw, - dislocations of the intra-articular disc, - parafunction of masticatory, mimic muscles and muscles of the tongue.
