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).
为研究伴有前牙拥挤的错牙合患者颞肌和咀嚼肌的功能状况,对54例患者进行了肌电图检查。发现咀嚼肌和颞肌功能失衡的程度取决于前牙拥挤的类型。在上颌前牙拥挤患者生理休息阶段的研究中,检测到颞肌生物电位振荡幅度的高指数(P<0.05)。研究确定,在上颌和下颌前牙拥挤患者处于咬合状态时,颞肌更活跃,这与咀嚼肌活动不足有关(P<0.05)。
