摘要： 目的:回顾性探讨研究Damon Q与3M smartclip两种自锁托槽在牙列拥挤非拔牙矫治病例中对上颌牙弓宽度和微笑时颊旁间隙大小治疗前后改变的差异。方法:选择牙列拥挤不拔牙矫治患者50例,其中28例采用Damon Q自锁托槽矫治技术,22例采用3M smartclip自锁托槽矫治技术。测量比较治疗前后姿势位微笑颊旁区面积比值和上颌牙弓宽度变化。结果:治疗后颊旁区面积在两组均有减少,但是组间和组内比较差异无统计学意义(P＞0.05)。治疗后牙弓后段宽度有所增加,在Damon组更为明显,第二前磨牙和第一磨牙区牙弓宽度治疗前后差值两组比较以及Damon组内治疗前后比较差异都有统计学意义(P＜0.05)。结论:Damon Q和3M smartclip两组的牙弓后段宽度均有增加,Damon组更为明显。两组治疗后微笑颊旁间隙有减小,但不明显。

Abstract: Objective: To evaluate the effect of Damon self-ligating and 3M smartclip bracket systems on buccal corridor area and maxillary arch width. Methods: A retrospective sample of consecutively treated patients using either 3M or Damon self-ligating brackets was analyzed to determine any differences in buccal corridor area both within and between groups. Pretreatment and post-treatment standardized frontal posed smile photographs and upper dental casts were taken. Results: There were no significant differences in any buccal corridor area either within or between the Damon and 3M smartclip system (P＞0.05). The inter second premolar and first molar width had significant changes in Damon system after treatment, and the changes had significant difference between two groups (P＜0.05). Conclusion: After treatment, arch width increases more in patients treated by Damon self-ligating brackets than 3M smartclip. There is no significant difference in buccal corridor width between patients treated with the Damon and 3M smartclip system.
