Electromyographic study of neuromuscular coordination of chewing muscular at the stages of protetic treatment

Abstract

The study of masticatory muscles allows timely detection of changes in their functional state, as well as to identify borderline pathological processes that can lead to the development of morphological and functional disorders in the maxillofacial region. This work was carried out in order to determine changes in the functional state of the masticatory muscles in patients with de-fects in the dentition in the lateral region before and after the orthopedic treatment. To achieve this goal, an electromyographic study of the masticatory muscles was performed in 95 patients with uni-lateral and bilateral defects of the dentition in the lateral region before and after restoration of the occlusal relationship of the dentition. As a result of the examination, pronounced malfunctions of the masticatory muscles were revealed in patients with defects in the dentition. After orthopedic treatment, a restoration of the balanced functioning of the muscular system of the maxillofacial re-gion was noted.
