【摘要】：目的:探讨Empower双核矫治器与Damon3-Mx矫治器拔牙矫治过程中牙齿移动的特点。方法:选择40例双牙弓前突患者,平均分为2组(n=20),拔除4个第一前磨牙后,一组采用Empower矫治器,另一组采用Damon3-Mx矫治器,均不采用支抗增强措施,治疗前后拍摄X线头颅定位侧位片,定点、测量19项测量项目,对测量结果进行2组独立样本t检验。结果:2组X线头影测量:牙性指标∠UI-SN、∠UI-PP、∠L1-MP、∠U1-L1、UIE-PTV、LIE-PTV治疗前后组内、2组间及2组变化量间差异有统计学意义(P0.05)。UM-PTV、LM-PTV、UIA-PTV、LIA-PTV、UL-EP、LL-EP、Z角治疗前后组内差异有统计学意义(P0.05),治疗后2组间差异无统计学意义(P0.05)。结论:应用Empower双核矫治器治疗双牙弓前突的患者,可以得到较好的支抗控制及前牙转矩控制,上下前牙内收明显,软组织侧貌改善明显。
[Abstract]:Objective: to investigate the characteristics of tooth movement during extraction with Empower binuclear appliance and Damon3-Mx appliance. Methods: 40 patients with double arch protrusion were divided into 2 groups on average. After 4 first premolars were extracted, one group was treated with Empower appliance. The other group was treated with Damon3-Mx appliance, without Anchorage enhancement measures. The lateral radiographs were taken before and after treatment, and 19 items of measurement items were measured. Results: the dental indices of the two groups were as follows: UI-SNN, 鈪，
