摘要
目的:通过测量牙弓宽度变化探讨Damon自锁托槽矫治安氏I类错(牙合)畸形的作用机制及疗效。方法:21例处于生长发育期的青少年安氏I类患者,采用Damon自锁托槽进行非拔牙矫治,治疗前后进行头影测量和牙弓宽度测量,分析牙弓宽度的变化特征。结果:矫治后患者牙列拥挤均解除,上、下颌牙弓宽度WU4、WU5、WU6、WL3、WL4、WL5、WL6在治疗后均明显增加(P<0.05)。上、下颌前牙治疗后唇倾度增加,UI-NA、LI-MP、LI-NB治疗前后差异均有统计学意义(P<0.05)。结论:Damon自锁托槽对于治疗安氏I类非拔牙矫治有特殊的疗效,可通过增加患者的牙弓宽度解除牙列拥挤,从而达到非拔牙矫治的效果。
Objective：To investigate the clinical effect of damon self-ligating system in the skeletal class I malocclusion cases by determinating the changes of dental arch width.Methods：Total 14 growth patients,all skeletal class I crowding cases,were treated with Damon self-ligating system of no-extraction. Before or after treatment, the dental arch width and cephalometric measurements were carried on and the variation features were analyzed. The variation characteristics of dental arch width were analyzed.Results：After the treatment,the dental crowding was corrected completely.And the dental arch width（WU4,WU5,WU6,WL3,WL4,WL5,WL6）were significantly increased（P〈0.05）. The upper and the lower anterior teeth showed lip tilting.UI-NA,LI-MP and LI-NB were increased after treatment.All of them showed statistically different（P〈0.05）. Conclusion：The treatment of skeletal class I crowding with Damon self-ligating non-extraction system was effective through the correction of dental crowding by increasing the dental arch width.
