摘　　要：目的比较自锁托槽与传统直丝托槽矫治拔牙病例的疗程。方法纳入需拔牙矫治的正畸病例60例随机分为2组,30例为试验组,采用Damon Q自锁托槽进行矫治,30例为对照组,采用传统直丝托槽矫治,记录并比较治疗完成的时间。结果试验组平均完成时间为640 d,对照组平均完成时间为686 d,两组差异无统计学意义(P>0.05)。结论自锁托槽在治疗拔牙病例时与传统直丝托槽相比,疗程未见明显的时间优势。Objective To compare the different treatment durations between self-ligating brackets and conventional brackets in extraction cases. Methods Sixty extraction cases were collected and randomly divided into two groups（n=30）, namely, experimental and control. The experimental group was treated with Damon Q self-ligating brackets. The control group was treated with conventional straight brackets. The durations of the treatments were recorded and compared between the two groups. Results The experimental group finished the treatment at an average of 640 d, where as the control group finished at an average of 686 d. However, no significant difference in treatment duration was found between the two groups（P〉0.05）. Conclusion The self-ligating brackets did not reduce the duration of the treatment compared with the conventional brackets.
