摘　　要：目的评价磨牙推联合微型种植体支抗远中移动磨牙的快速性和有效性。方法选取2011年1月~2013年12月就诊的26例适合远中移动磨牙的安氏Ⅱ类错牙合患者,随机分为实验组和对照组,实验组13例,使用磨牙推联合微型种植体支抗远中移动磨牙,对照组13例,单纯使用微型种植体支抗远中移动磨牙。术前术后取研究模型,拍摄头颅侧位片。结果实验组恢复Ⅰ类咬合平均需（3.94±0.39）个月,对照组为（5.37±0.45）个月,差异有统计学意义（P〈0.05）;实验组平均磨牙远中移动（5.05±0.52）mm,对照组为（4.75±0.24）mm,差异无统计学意义（P〉0.05）。结论实验组较对照组能更快速有效远中移动磨牙,磨牙推联合微型种植体支抗技术值得临床推广。Objective To investigate the quickness and effectiveness of Lokar maxillary molar distalization appliance combined with micro - implant anchorage （MIA）in distoplacement of upper molars. Methods Twenty-six patients with Angle class II malocclusion who visited the Oral Outpatient Department of Guangxi Wuzhou Traditional Chinese Medicine （TCM）Hospital from January 201 1 to December 2013 and were suitable for the molar distoplacement were chosen in this study.All the patients were randomly divided into an experi-ment group （n =13）and a control group （n =13）according to different treatment methods.Lokar molar dis-talization appliance combined with MIA was used in the experiment group for molar distalization,and the con-trol group used MIA alone for molar distalization.The pre- and post-operative research models were pre-pared and the lateral head extraoral radiographic examination was done. Results The average time to restore Angle classⅠocclusion relationship in the experiment group was （3.94 ± 0.39 ）months,and in the control group it was （5.37 ±0.45）months,comparison of the two groups showed statistically significant difference （P 〈0.05）.The average distance of molar distoplacement was （5.05 ±0.52）mm in the experiment group, and it was （4.75±0.24）mm in the control group,there was not significant difference （P 〉0.05）. Conclu-sion The experiment group can distoplace upper molars more quickly and efficiently than the control group. Lokar maxillary molar distalization appliance with MIA deserves clinical recommendation.
