摘要： 目的: 研究不同年龄女性正畸患者上切牙内收后上唇软组织位置的改变规律。方法: 女性前牙前突拔牙病例63例依年龄分为青少年组和成年组。对正畸治疗前后X线侧位片软硬组织共9个指标进行测量。分析软硬组织变化量的相关性。结果: 治疗后,两组患者U1-SN显著减小,U1切缘、颈部、上唇凹点、突点、下点位置显著内收,上唇长度及厚度增大。上唇突点与U1颈部内收量、上唇下点与U1切缘内收量相关度最高。青少年组和成年组切缘与上唇下点内收量比分别为1∶0.54和1∶0.65,U1颈部与上唇突点内收量比分别为1∶0.50和1∶0.79。结论: 上唇突点内收量与切牙颈部内收相关性高,上唇下点内收量与切牙切缘内收量相关性高。

Abstract: Objective: To study upper lip soft tissue position changes of different age female after orthodontic retracting anterior teeth. Methods: 63 female orthodontic patients with protrusion anterior teeth were divided into adolescent group and adult group according to the age. Pre- and post-treatment cephalometric X-rays were performed, and 9 measurement items were measured. The correlations of the change values were analyzed. Results: After the treatment, the angle of U1-SN significantly reduced. The position of U1 incisal tip, U1 cervical point, upper lip sulcus, upper lip flange, and stomion superius significantly retracted. Upper lip length and thickness increased. The change values of position of upper lip flange and U1 cervical point had high-positive correlation, and the change values of position of stomion superius and U1 incisal tip had high-positive correlation. In adolescent group and adult group, the adduction ratio of the U1 incisor tip to stomion superius was 1∶0.54 and 1∶0.65, the adduction ratio of the U1 cervical point to upper lip flange was 1∶0.50 and 1∶0.79, respectively. Conclusion: The change values of position of upper lip flange and U1 cervical point had high-positive correlation, and the change values of position of stomion superius and U1 incisal tip had high-positive correlation.
