Sixty-six growing Class II, division 1 patients were treated with a headgear-reactivator combination. The appliance included a mandibular advancement mechanism, that was reactivated during treatment. Lateral roentgenograms in centric occlusion were taken at the beginning and end of the active treatment period. At the end of treatment the sagittal jaw relationship was significantly improved. However, considerable maxillary incisor retroclination and mandibular incisor proclination also occurred. No marked changes in the vertical skeletal situation could be demonstrated.
66例正在生长发育的安氏II类1分类患者接受了头帽-激活器联合矫治。矫治器包括下颌前导装置，在治疗过程中进行激活。在主动治疗期开始和结束时拍摄正中咬合位的头颅侧位片。治疗结束时，矢状向颌骨关系得到显著改善。然而，上颌切牙明显舌倾和下颌切牙唇倾也同时出现。垂直向骨骼情况未见明显改变。
