[The characteristics of the muscular activity of the maxillofacial area in persons with partial tooth loss depending on the extent of the dentition defect].
The electromyogram (EMG) amplitude of the masticatory and temporal muscles is decreased and EMG amplitude of suprasublingual muscles increased during mastication or voluntary occlusion in patients with class I dentition defects in comparison with the controls. The changes were the greater, the more antagonist pairs were missing. The duration of masticatory period and the number of masticatory movements increased. The most notable changes in the muscular activity are observed in subjects with 4 antagonist pairs missing.
