【摘要】：目的:比较Damon自锁托槽与Tip-Edge plus差动直丝弓托槽在拔牙病例中对前牙转矩的控制情况。方法:选取2012~2014年在南京大学附属口腔医院正畸科治疗的拔除4颗前磨牙的患者,分别采用Tip-Edge plus差动直丝弓矫治技术(TP组)和Damon自锁托槽(DM组)矫治技术完成治疗,各20例;拍摄数字化头颅侧位片,测量分析患者治疗前后的变化。结果:治疗前,上颌切牙倾斜度(U1-SN°)两组没有明显差异[TP组(112.45±6.39)°,DM组(111.87±6.33)°];正畸治疗后前牙明显内收,两组上前牙转矩无统计学差异[TP组和DM组分别为(99.32±7.33)°和(99.57±4.74)°];治疗后上下唇突度显著减小,侧貌明显改善,Z角两组之间没有显著差异[TP组和DM组分别为(66.74±10.3)°和(68.11±9.54)°]。结论:Damon自锁托槽与Tip-Edge plus托槽在拔牙病例中都能有效的控制前牙转矩,两组间无明显差异。
[Abstract]:Objective: to compare the torque control of the anterior teeth between the self-locking brackets and the Tip-Edge plus differential straight arch brackets. Methods: four premolars were extracted from orthodontic department of affiliated Stomatology Hospital of Nanjing University from 2012 to 2014. The patients were treated with Tip-Edge plus differential wire appliance (TP group) and plus self-locking bracket group (DM group), 20 cases each. Digital cephalic lateral radiographs were taken to measure and analyze the changes of patients before and after treatment. Results: before treatment, there was no significant difference between the two groups in maxillary incisor inclination (U1-SN 掳) [TP group (112.45 卤6.39) 掳vs DM group (111.87 卤6.33) 掳], the anterior teeth were obviously adducted after orthodontic treatment, and there was no significant difference in the torque of upper and lower teeth between the two groups [TP group and DM group were 99.32 卤7.33 掳and 99.57 卤4.74 掳], and the upper and lower labial protrusions decreased significantly after treatment. There was no significant difference between the two groups [66.74 卤10.3 掳in TP group and 68.11 卤9.54 掳in DM group]. Conclusion the torque of anterior teeth can be effectively controlled by both the self-locking bracket and the Tip-Edge plus bracket. There is no significant difference between the two groups.
