This retrospective study assessed the outcome of orthodontic treatment of 264 patients with Class II division 1 malocclusion (overjet greater than 6 mm). The sample comprised patients who had completed their fixed appliance orthodontic treatment at a regional hospital orthodontic unit in the Republic of Ireland. The PAR Index (Peer Assessment Rating) was used to evaluate treatment outcome using before and after treatment study casts. The results revealed that treatment for this particular type of malocclusion was highly effective with a very few patients failing to benefit from their orthodontic treatment.
这项回顾性研究评估了264例安氏II类1分类错牙合畸形（覆盖大于6毫米）患者的正畸治疗效果。样本包括在爱尔兰共和国一家地区医院正畸科完成固定矫治器正畸治疗的患者。使用PAR指数（同行评估等级），通过治疗前后的研究模型来评估治疗效果。结果显示，针对这种特殊类型的错牙合畸形的治疗非常有效，只有极少数患者未能从正畸治疗中获益。
