摘要: 目的 测量和评估成人安氏Ⅱ类1分类错牙合患者正畸前后的唇部软组织形态。方法 选择30例已经完成正畸治疗的安氏Ⅱ类1分类错牙合成年患者,术后模型及头影测量的数据均在正常范围内。对其正畸前后正面像和头颅侧位片唇红的矢状向厚度和垂直向厚度进行测量。结果 正畸后上唇垂直向厚度有变小的趋势,下唇垂直向厚度有变大的趋势,差异有统计学意义(P<0.05)。上唇矢状向唇红部组织厚度术后有增大的趋势,下唇矢状向唇红部组织厚度矫正后有减少的趋势,且有统计学意义(P<0.05)。上颌上中切牙(U1C)矢状向内收量与上唇红(TUL)的内收呈显著正相关,下唇红(TLL)矢状向位置的变化与下颌切牙突点(L1C)位置变化存在正相关,下唇红(TLL)矢状向位置的变化与上颌切牙突点(U1C)位置变化存在正相关。结论 安氏Ⅱ类1分类错牙合成人患者拔牙矫治后,可以通过切牙回收量较好地预测其唇部软组织正畸前后的矢状向厚度和垂直向厚度变化。

Abstract: Objective Lip soft tissue were measured and assessed before and after orthodontic treatment of Class Ⅱ division 1 adults in order to instruct the clinical work. Methods A total of 30 post-treatment adult patients of Class Ⅱ division 1 were selected, whose post-treatment model and cephalometric data were within the normal range. The pre- and post-treatment front image and lateral cephalograms lip sagittal thickness and vertical thickness measurement. Results Post-treatment upper lip vertical become thinner and lower lip vertical thickness is bigger which has a statistically significant gap. Upper lip vermilion of the initial tissue thickness after treatment increased, lower lip vermilion of initial tissue thickness had a tendency to decrease after treatment, and there was statistical significance. The retraction of upper incisor cervical point (U1C) was positively correlated with upper lip retraction (TUL). The retraction of lower incisor cervical point (L1C) was positively correlated with lower lip retraction (TLL). And the retraction of upper incisor most anterior point was positively correlated with lower lip retraction. Conclusion Upper and lower lip retraction in Class Ⅱ division 1 Chinese adults could be effectively predicted by the retraction of incisors after extraction orthodontic treatment.
