Research objective is to reveal functional changes of masticatory muscles in patients with fractures of lower jaw in combination with dentition abnormalities. Materials. 72 patients with such pathology have been examined. As a result of clinico-laboratory methods of research functional disturbances of masticatory muscles and their changes during the course of surgical and orthopaedic treatment have been revealed. It has been established that restoration of amplitude of biopotentials of masticatory muscles is possible at easy stage of musculo-articular dysfunction. Conclusion. At average and severe stages of dysfunction normal parameters may be reached.

Diagnosis of occlusion in combination with the musculo-articular dysfunction is based on data from medical history, results of clinical and special methods of research: analysis of diagnostic models of jaws in the articulator, the results of radiological methods of investigation: orthopantomography, teleroentgenography, tomography of temporomandibular joints, magnetic resonance imaging, electromyography of masticatory muscles; functionography and other methods of investigation

The research work is dedicated to study of bioelectric activity of masticatory muscles of adult patients with distal occlusions. The research is based on the results of electromyographic analysis of bioelectric activity of masticatory muscles of 47 patients with distal occlusions. The results of electromyographic analysis have allowed establishing the criteria of masticatory muscles adaptation to new functional conditions of masticatory system formed in the process of treatment of patients with distal occlusions. The established criteria can be used to define objectively the duration of masticatory muscles adaptation period during the stages of complex treatment of patients with distal occlusions

The aim of the research is a literature review about the problem of temporomandibular joints and masticatory muscles in patients with teeth occlusion and teeth row disturbances. Teeth occlusion and teeth row disturbances are widespread pathology of maxillofacial area, that can lead to different pathology alterations of masticatory system including musculo-articular dysfunction. Some specialists consider that the key factor of pathogenesis of musculo-articular dysfunction is occlusion disturbances, by the other opinion - discoordination of muscle contraction. Thus occlusive and muscular disorders are leading in pathogenesis and clinic of musculo-articular dysfunction
