By means of standardized transcranial oblique lateral (TOL) radiographs, the position of the mandibular condyles in the glenoid fossae of 14 patients with Class II division 1 malocclusion was studied at the beginning of treatment with or without functional appliances placed in position, and also at the end of treatment. A significant increase in the distance between the upper point of the condyle and the glenoid fossa was found when the appliance was worn for the first time. This displacement was found to disappear at the end of the treatment even when the appliance was placed in position.
通过标准化经颅斜外侧（TOL）X线片，研究了14例安氏II类1分类错牙合患者在治疗开始时（无论是否佩戴功能性矫治器）以及治疗结束时下颌髁突在关节窝中的位置。首次佩戴矫治器时，发现髁突上点与关节窝之间的距离显著增加。即使在治疗结束时仍佩戴矫治器，这种移位也会消失。
