Electromyography is the most objective and reliable technique for evaluating muscle function and efficiency by detecting their electrical potentials, assessing the extent and duration of muscle activity. The main aim of surface electromyography is to detect the signals from many muscle fibers in the area of the detecting surface electrodes. Studies by many foreign and domestic researchers have identified the impact of sagittal malocclusion on the function of the masticatory muscles. The aim of our study was to establish the relationship between the distal occlusion and the activity of the masticatory muscles in orthodontic patients. Methods: 15 orthodontic patients aged (15.33±0.86) years with a distal occlusion were examined. The results of clinical and functional examinations during and after orthodontic treatment were analysed. An electromyographic study of the masticatory and temporomandibular muscles in the examined patients was performed. Patients were examined in accordance with the main requirements of the Helsinki Declaration for Biomedical Research (Seoul, 2008). Scientific novelty. The electromyographic activity of the biopotentials of the masseter and masseter muscles in stable and advanced position of the mandible in 15 patients with a distal occlusion was compared. A significant difference was found between stable and asdvanced position of mandibular in decreasing of the following parameters: in the maximum chewing amplitude of the left anterior temporalis muscle, the maximum chewing amplitude of the right anterior temporalis muscle, n the maximum chewing amplitude of the left masseter muscle, and the maximum chewing amplitude of the right masseter muscle. Conclusion. Тhe electromyographic study of the masticatory and temporomandibular muscles in patients with a distal occlusion, functional changes in the activity of the masticatory muscles at rest and in the advanced position of the mandible were revealed.
