目的:探讨Damon Q自锁托槽对安氏Ⅰ类错畸形牙的治疗效果,以供治疗此疾病给予参考。方法:我院于2010年3月-2012年8月收治了116例安氏Ⅰ类错畸牙患者,收集这些患者的临床资料,对这些患者采取Damon Q自锁托槽的治疗方法。并且对治疗前后的牙齿情况进行对比,分析治疗的效果。结果:将矫正前和矫正后进行对比,上颌牙的宽度和下颌牙的宽度(WU3、WU4、WU5、WU6)在进行治疗之后,明显有所增加。上颌前牙、下颌前牙(U1-NA、L1-MP、L1-NB)在进行治疗以后,后唇的倾度明显有所增加。治疗前后的差异具有统计学意义。结论:Damon Q自锁托槽矫治安氏Ⅰ类错畸形牙弓宽度,通过增加牙弓宽度来矫正牙齿,具有比较好的疗效,值得临床推广。
Objective: To investigate the therapeutic effect of Damon Q self-ligating brackets on Angle Class I malocclusion for the treatment of this disease. Methods: From March 2010 to August 2012, 116 cases of Class Ⅰ malocclusion were treated in our hospital. The clinical data of these patients were collected. The patients were treated with Damon Q self-ligating brackets. And before and after treatment of teeth compared to analyze the effect of treatment. RESULTS: Before and after correction, the maxillary tooth width and mandibular tooth width (WU3, WU4, WU5, WU6) were significantly increased after treatment. Anterior teeth, mandibular anterior teeth (U1-NA, L1-MP, L1-NB) after treatment, the lip inclination increased significantly. The difference between before and after treatment was statistically significant. Conclusion: Damon Q self - ligating brackets for Class Ⅰ malocclusion arch width, by increasing the dental arch width to correct teeth, has a good effect, is worthy of clinical promotion.
