摘　　要：作者采用与计算机图象处理技术相结合的磁电转换式下颌运动轨迹描记仪对１３例恒牙初期前牙反牙合患者正畸治疗前后的下颌边缘运动范围及轨迹进行观察记录，发现：治疗前后下颌边缘运动范围发生了明显改变，后退的垂直及水平相滑动均减少，侧移的对称性增加。The investigation was conducted to record the border movement tracings of 13 patients in early permanent anterior crossbite malocclusion before and after orthodontic treatment.These records were made by a K5AR mandibular kinsiograph.The result indicated that the ranges and tracings of mandibular border movement were improved significantly.
