The aim of the study was to elaborate Diagnostic criteria for the transition from occlusal splints to non-removable orthopedic appliances in patients with TMJ dysfunction with disc disorders. The study involved 95 patients with the clinics of TMJ dysfunction. An examination included electrovibrography and computerized electromyography in order to assess diagnostic value of the methods. Electrovibrography is a method based on arthrophonography, which makes it possible to obtain data on intraarticular noise in the TMJ. Computerized electromyography provides an objective assessment of the bioelectrical activity of the masticatory muscles in occlusive disorders, changes in the height of the lower facial area, and their relationship with the development of musculo-articular dysfunction of the TMJ and allows monitoring the effectiveness of orthopedic treatment. Within the normal function of the jaws the graphic trajectories of mandibular movements are within the limits of norm, and in the case of a violation of the TMP function, the graphic and linear indices are significantly different from the normal values.
