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 investigate the difference between Tip-Edge Plus and Damon self-ligating brackets in torque control in extraction cases. Methods: Patients treated in Nanjing Stomatological Hospital in 2012～2014 who needed four premolar extraction were selected, with 20 cases treated by the Tip-Edge Plus appliance (TP group) and 20 cases treated by the Damon self-ligating brackets (DM group). Digital cephalograms were recorded and cephalometric analyses were carried out before treatment and after treatment. Results: No difference was observed before treatment in upper incisor inclination (TP group 112.45±6.39°, DM group 111.87±6.33°); significant retraction of anterior incisors were founded with no difference in torque control of both upper incisors (TP group 99.32±7.33°, DM group 99.57±4.74°); the protrusive lips were significantly retracted with remarked profile improvement, and no difference in Z angle was observed (TP group 99.32±7.33°, DM group 99.57±4.74°). Conclusion: Both the Tip-Edge Plus and Damon self-ligating brackets could effectively control the torque of front teeth, and no differences were found in two groups.
