本研究对３０名成人骨性ＡｎｇｌｅⅢ类错合患者咀嚼运动和正中 位大力咬合的肌电活动进行测量，并与正常 成人比较发现：成人骨性ＡｎｇｌｅⅢ类错 正中 位大力咬合时嚼肌、颞肌前后束肌电活动均较正常成人低，肌力较小。咀嚼运动时．成人骨性ＡｎｇｌｅⅢ类错 嚼肌、颞肌肌电活动均较正常成人低，咀嚼循环活动期较正常成人长．间歇期较正常成人短。
In this study, masticatory and median masticatory activities were measured in 30 adult patients with skeletal Class III Angle mismatch. Compared with normal adults, the adult skeletal Class III malocclusion was characterized by strong masticatory and temporal muscles Myoelectrical activities before and after beam were lower than normal adults, muscle strength smaller. When chewing exercise. Adult skeletal Angle class Ⅲ chewing muscle, temporal muscle myoelectric activity were lower than normal adults, chewing cycle activity longer than normal adults. Intermittent shorter than normal adults.
