To study functional condition of temporal and masticatory muscles in patients with malocclusion, complicated by crowding of frontal teeth, 54 patients were subjected to electromyography. It was found that the degree of functional imbalance of masticatory and temporal muscles depends on the type of crowding of frontal teeth. Investigating phases of physiological rest in patients with crowding of maxilla frontal teeth high indices of oscillation amplitude of temporal muscles biopotentials (P < 0,05) were detected. The study has established that in state of compression in patients with crowding of frontal teeth of maxilla and mandibula temporal muscles are more active, what is connected with insufficient activity of masticatory muscles (P < 0,05). |
