摘　　要：目的:运用PAR指数评价摆式矫治器非拔牙矫治安氏Ⅱ1类错的效果。方法:选取摆式矫治器治疗安氏Ⅱ1类错病例32例,运用PAR指数对每一病例矫治前后的石膏模型进行评分,并作配对t检验。结果:所有患者治疗结束时都达到个别正常标准,PAR指数得分平均减少31分。结论:摆式矫治器可以有效治疗部分安氏Ⅱ1类错,同时避免了拔牙,对轻、中度患者是一种可取的治疗手段。Objective： Assess the clinical effect of pendulum in treating class Ⅱ malocclusion in terms of peer Assessment Rating （PAR index）. Method-32 class Ⅱ malocclusion cases treated with pendulum are chosen .PAR index is used in assessing every patient＇s mode before and after orthodontic therapy,and pair t test is performed. Result：All patients reach normal occlusion after treatment. 31 points or 91 percents in PAR index decrease when the treatment is over. Conclusion. Some kinds of class Ⅱ malocclusion can be treated effectively by pendulum without tooth extraction.
