通过对４２例前牙反 应用ＦＲⅢ型功能矫治器、上颌 垫矫治器及方丝弓矫治器的矫治，探讨其功能特点和矫治原则，得出：（１）功能性反 者ＩＣＰ前移。骨性反 者ＩＣＰ正常，两者的临床鉴别不能单纯看下颌能否后退至对刃位；（２）前牙反矫治的咬合重建，不能以后退接触位为基准，只有在肌位建才是最符合生理的；（３）固定矫治对反覆小于３ｍｍ者可不加垫，固定矫治反覆大于３ｍｍ者及活动矫治应加垫，以抬高咬合。
Through the treatment of 42 cases of anterior teeth reaction with FR Ⅲ functional appliance, maxillary pad appliance and square wire appliance, the functional characteristics and the principle of orthodontic treatment were discussed. The results were as follows: 1. Osteoid anti-ICP normal, the clinical identification of both can not simply look at the jaw can retreat to the edge position; (2) anterior teeth anti-orthodontic occlusal reconstruction can not be based on the back contact position, only in the muscle position is The most consistent with physiology; (3) fixed orthodontics repeated less than 3mm may not be padded, orthodontic treatment more than 3mm repeated and active correction should be padded to raise bite.
