摘要：

目的    探讨Free-edge 六翼托槽矫治安氏Ⅱ1类错牙合的效果。方法    选择福建医科大学附属协和医院口腔科2004—2008年收治的36例安氏Ⅱ1类病例，应用Free-edge 六翼托槽进行矫治，对比矫治前后的头影测量项目。结果    上颌中切牙角（U1-SN）及上颌中切牙切端至NA线的垂直距离（U1-NA）明显减小，表明上切牙明显内收。上颌支抗磨牙无明显前移。上切牙与下磨牙无明显伸长。下颌平面与牙合平面无明显逆时针旋转。结论    应用Free-edge 六翼托槽可最大限度减少额外支抗的使用，并可避免传统方丝弓技术Ⅱ类牵引所可能导致的负面影响。

Abstract:

Objective    To study the method of the treatment for Angle’s Class Ⅱ division 1 malocclusion with Free-edge bracket. Methods    A total of 36 patients with Angle’s Class II division 1 malocclusion were treated by Free-edge bracket. Lateral cephalogams were analyzed. Results    The U1-SN and U1-NA reduced markedly，pointing out that the upper incisors adducted markedly， the upper molars hardly moved ahead，and the upper incisors and the lower molars hardly extruded. Conclusion    Application of Free-edge bracket can reduce the use of added anchorage， and can avoid the side effects of the traditional Edgewise technique.
