Determination of the range of motion and motor pattern of the mandible are important elements at the stage of diagnostics of TMJ dysfunction syndrome [1] and at the stage of analysis of the functional space in the process of manufacturing of the occlusal splint [2]. Clinically and with the help of Arcus Digma 1, Arcus Digma 2 virtual articulators we have studies dynamic parameters and patterns of mandible movements in 97 patients with TMJ dysfunction syndrome. All the patients were scheduled for occlusal splints. We have determined functional type and characteristics of the bite, parameters for adjustment of the mechanical articulator. Analysis of correlations of articular and occlusal parameters showed that they affect the motor stereotype, which provides for the formation of unilateral hypermobility and forced lateral displacement of the mandible in patients with TMJ dysfunction syndrome. Initially the examined patients showed no hypermobility in the temporomandibular joints as well as generalized hypermobility [3].
