The hypertone of chewing muscles is the leading reason of development of pain of non-odontogenic character in maxillofacial area. This pathology is rather widespread, at the same time has permanent character and is characterized average or heavy degree of expressiveness of clinical symptoms. Muscular pains considerably reduce working capacity and worsen quality of life of patients. Treatment of a hypertone of chewing muscles is relevant in stomatology. For clear understanding of genesis of development of muscular frustration in work the anatomy of a temporal and mandibular joint and chewing muscles is in detail presented systems. Modern methods of treatment of a hyper tone of chewing muscles include correction of occlusion that doesn’t eliminate a painful symptom; orthopedic and orthodontic treatment with application a cap. However, application of above-mentioned methods is rather effective, there is no exact understanding of the mechanism of their action. At some patients the temporary improvement of a state is noted, – gets the chronic sluggish long course of development of a disease which doesn’t give in by any known methods subsequently from others. Dentists perfectly understand this fact, at the same time the disappointment from the treatment comes in spite of the fact that all efforts were bent on improvement of knowledge in the field of factors predictors of development of pathology, modern methods of diagnostics and treatment of muscular frustration. In this work the use of the pneumoexercise machine mouth gag as the device relaxing muscles and separating device on the one hand, and possibilities of his use as a stimulator of process of the return development of the available already structural and functional changes of muscle tissue with another is proved. Accurate indications and contraindications to use of this device are submitted. It is recommended to use the device as the low-invasive method which isn’t leading to irreversible consequences. Further need of development of practical recommendations on uses of the pneumoexercise machine mouth gag as is obvious to patients and their parents, and to dentists in the medical and preventive purposes.
