摘　　要：目的:探讨摆式矫治器在大龄青少年错矫治中的临床效果。方法:安氏II类错12例,平均年龄14.5岁,男4例,女8例。所有病例上颌第二磨牙已完全萌出。使用摆式矫治器推上颌第一磨牙向远中移动,当上下磨牙达到轻度III类关系时停止加力,维持3个月。治疗前后均拍摄头颅侧位片。比较治疗前后患者的牙与骨骼变化。结果:第一磨牙平均远中移动5.60mm,远中旋转3.49°,整体移动约80%。第二磨牙平均远中移动5.19mm,远中旋转6.40°,整体移动约50%,无明显骨骼改变。Objective： Research the clinical effect of pendulum in treating older adolescent. Method： 12 patients with Class Ⅱ malocclusion are chosen. Male 4 cases and female 8 cases. The maxillary second molars are fully errupted in all patients. Pendulum is used to move first molar distally. When Class Ⅲ molar relationship appears, quit pendulum activation,then keep pendulum in mouth for 3 months. Cephalogram are taken before and after pendulum treatment in all pa- tients. Compare dental and skeletal changes in this stage. Result： Maxillary first molars move by 5.60 mm distally, rotate by 3.49° distally, total movement are 80%. Second molars move by 5.19 mm distally, rotate by 6.40° distally, total movement are 50%. There is no obvious skeletal change taken place. Conclusion： Adventagious clinical effect can be found in pendulum when treating older adolescent.
