错He畸形的下颌功能运动轨迹及其分类

目的 对错Ｈｅ畸形者的下颌运动轨迹进行分类。方法 对错Ｈｅ畸形患者的口颌功能进行临床检查并以下颌运动轨迹描记进行轨迹分析。结果 对２２３例错Ｈｅ（男１０６名,女１１７名,平均年龄１４．６岁）的观察表明,将近４０％的患者存在功能性错Ｈｅ,特定的错Ｈｅ类型常呈现出特征性的下颌运动轨迹。同时发现,下颌运动轨迹受上下颌骨、肌肉、关节及牙齿等综合因素的影响。结论 本项研究总结归纳出功能性错Ｈｅ的分类方法（包

Analysis of mandibular movement and functional classification for malocclusion patients]

OBJECTIVE: To classify the paths of mandibular movements of patients with malocclusion. METHODS: 223 patients were examined clinically and mandibular Kinesiograph(MKG) was applied. RESULTS: Each kind of malocclusion has its corresponding characteristic paths of mandibular movement. The paths of mandibular movements of patients with the same class of malocclusion are similar. It was also found that the mandibular movement was related not only with occlusion but also with jaws, muscles, and joints. Meanwhile, they affect each other. CONCLUSION: Functional malocclusion classification includes functional class I, II, III and IV malocclusion.
