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（P ＜0．05）。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（P＜0．05），治疗后2组间差异无统计学意义（P ＞0．05）。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。
目的：探討 Empower 雙覈矯治器與 Damon3-Mx 矯治器拔牙矯治過程中牙齒移動的特點。方法：選擇40例雙牙弓前突患者，平均分為2組（n ＝20），拔除4箇第一前磨牙後，一組採用 Empower 矯治器，另一組採用 Damon3-Mx 矯治器，均不採用支抗增彊措施，治療前後拍攝 X 線頭顱定位側位片，定點、測量19項測量項目，對測量結果進行2組獨立樣本 t 檢驗。結果：2組 X 線頭影測量：牙性指標∠UI-SN、∠UI-PP、∠L1-MP、∠U1-L1、UIE-PTV、LIE-PTV 治療前後組內、2組間及2組變化量間差異有統計學意義（P ＜0．05）。UM-PTV、LM-PTV、UIA-PTV、LIA-PTV、UL-EP、LL-EP、Z 角治療前後組內差異有統計學意義（P＜0．05），治療後2組間差異無統計學意義（P ＞0．05）。結論：應用 Empower 雙覈矯治器治療雙牙弓前突的患者，可以得到較好的支抗控製及前牙轉矩控製，上下前牙內收明顯，軟組織側貌改善明顯。

Objective:To study the tooth movement in the orthodontic treatment by Empower appliance following tooth extraction. Methods:40 cases with bimaxillary dentoalveolar protrusion were divided into 2 groups(n =20).After extraction of all first premolars of each case,the patients were treated by Empower appliance and Damon3-Mx appliance respectively without palatal enhance measure. Before and after treatment the patients were examined by cephalometric roentgengraphy with 1 9 measurements,the data were analysed by independent sample t test.Results:Tooth indicators∠UI-SN,∠UI-PP,∠L1 -MP,∠U1 -L1 ,UIE-PTV and LIE-PTV before and after the treatment in each group,and the variations between the 2 groups were significantly different(P <0.05).UM-PTV,LM-PTV, UIA-PTV,LIA-PTV,UL-EP,LL-EP and Z Angle were significant changed after treatment(P <0.05),no significant difference was found between the 2 groups after treatment(P >0.05).Conclusion:Empower appliance is more effective than Damon3-Mx in the treatment of bimaxillary dentoalveolar protrusion by anterior tooth torque control,upper and lower front teeth adduction and improvement of soft tissue lateral profile.
