Electromyography of masticatory muscles is an objective criteria for the adaptation of patients to orthopedic constructions. The aim of the study was to evaluate the adaptation of masticatory muscles of patients with terminal defects of dentition made a prosthetic appliance for teeth with implant constructions with a large number of supports and removable denture. As a result, when patients with terminal defects of the dentition are made prosthetic appliance with the help of implant structures with a large number of supports in 3 months, the maximum aproaching of the bioelectrical potentials of the masticatory muscles to the norm is observed. When patients are made prosthetic appliance with removable orthopedic structures, hypertension of the masticatory muscles decreases, but does not reach physiological values. It is recommended to use the method of surface electromyography of the masticatory muscles to monitor the effectiveness of orthopedic treatment and the degree of adaptation of the patient to the manufactured structures.
