摘要： 目的 探讨拔牙治疗对高角患者颅颌面垂直向结构的影响。方法 回顾性分析2014年2月—2015年8月进行牙齿矫治的高角病例76例,根据矫治方案不同分为两组,即观察组采用正畸拔除前磨牙矫治方案40例,对照组采用非拔牙矫治方案36例。通过头颅侧位X线片分别测量两组患者经过两种不同矫治方案治疗前、后颅颌面垂直向结构的变化。结果 两组患者治疗后ANS-Me、L6-MP、N-Me、U6-PP均较治疗前增加显著(P＜0.05);观察组与对照组患者Y-axis、L6-MP比较,差异均具有统计学意义(P＜0.05)。结论 拔牙矫治前后,下颌平面角与生长方向的结构无明显改变,观察组患者磨牙高度高于对照组。

Abstract: Objective To investigate the effect of extraction therapy on the vertical structure of craniomaxillofacial region in patients with high angle.Methods A retrospective analysis was conducted for 76 cases of high angle cases in orthodontics from February 2014 to August 2015 who were divided into two groups according to treatment regimens.The observation group (n=40) was treated with orthodontic premolars,and the control group (n=36) used using non-extraction treatment program.The changes of craniomaxillofacial vertical structure of the two groups by two different treatment regimens were measured using X-rays.Results After treatment,ANS-Me,L6-MP,N-Me and U6-PP in the two groups were significantly higher than those before treatment (P<0.05).There were differences in Y-axis and L6-MP between the two groups (P<0.05).Conclusion There is no significant change in the structure of mandibular plane angle and growth direction before and after orthodontic treatment.The height of molar is higher in the observation group than in the control group.

Key words: Extraction treatment, High angle, Craniomaxillofacial vertical structure
