摘要： 目的： 应用全景片评估上颌阻生尖牙的特征（角度、线距和位置）对正畸牵引时间的影响。方法： 选取60例进行正畸牵引治疗的上颌单侧阻生尖牙患者，通过全景片测量治疗前患者上颌阻生尖牙的特征（角度、线距和位置），采用SPSS19.0软件包中的多元回归分析影响正畸牵引时间的相关因素。结果： 治疗前阻生尖牙的角度、线距和位置与正畸牵引时间显著相关，性别和左右侧位置对牵引治疗时间无显著影响。结论： 阻生尖牙的角度、距离和位置可以预测正畸牵引时间。

Abstract: PURPOSE: To evaluate the influence of pretreatment radiographic features (angle, distance, and location) on the duration of active orthodontic traction. METHODS: Sixty maxillary unilateral impacted canines were selected to analyze the panoramic features(angle, line spacing, and location) in pre-treatment patients， the results were evaluated using SPSS19.0 software package for multivariate regression analysis. RESULTS: Pretreatment radiographic variables (angle, line spacing, and location) were significantly associated with the duration of orthodontic traction. The sex and site of impaction did not significantly affect the duration of traction. CONCLUSIONS: Impacted canine angle, distance and position can predict the orthodontic traction time.
