Electromyographic characteristics of the functional state of the masseter and temporal muscles proper in patients using a dental splint in comparison with the parameters of the physiological rest of the lower jaw

Injuries to the maxillofacial region, in particular, fractures of the mandible, account for 70-85 % of all fractures of the facial bones and significantly increase the duration of postoperative rehabilitation of patients. The need for immobilization and postoperative rehabilitation of patients is due to the risk of complications such as contracture of the lower jaw, increased muscle tone, violation of the occlusal relationship of the teeth, and as a result, the development of pathology from the temporomandibular joint and significant problems subsequently providing orthopedic care to patients. The article analyzes the electromyographic indicators of the functional state of the temporal and masticatory muscles proper in healthy patients in a state of physiological rest of the lower jaw. The results obtained are compared with the electromyographic parameters of muscles using a dental splint with communicating channels for temporary immobilization of the jaws. These studies prove the benefits of using a dental splint and the detection of normal electromyographic muscle parameters in healthy patients.
