目的:观察腭侧微种植体支抗在推磨牙远中移动中的治疗效果. 方法:选取安氏Ⅱ类错牙合患者20例,在腭部共植入微种植体25颗,利用微种植体与双侧第一前磨牙形成三角形整体做为支抗单位推磨牙向远中. 拍摄磨牙移动前后的X线头颅侧位片,记录上颌磨牙及切牙移动情况,并进行统计分析.结果:所有病例都达到了预期的矫治效果,磨牙达到中性关系、面型得到较好的改善. 上颌第一磨牙平均向远中移动(4.69±1.88)mm;上颌磨牙的压低、颊倾、远中倾斜,治疗前后均无显著性差异. 结论:腭侧微种植体作为强支抗,能成功远移上颌磨牙,没有出现支抗丧失,是非常有效的非依从性远移磨牙的方法.

Objective:To evaluate the use of palatal micro implant as strong anchorage in distalization of maxillary molars. Method:Using 25 Micro implants were implanted into palate of 20 angle class II patients. maxillary molar teeth were distalized by a triangle-shaped anchorage units comprised by Micro implant and bilateral first premolar. The data of move-ment of maxillary molars and incisors were evaluated with Cephalometric technique and analyzed by statistical methods. Re-sult:The maxillary molars were distally moved by (4.69±1.88)mm. There were no significant differences in extrusion,rota-tion and tilt of the maxillary molars before and after treatment. All patients achieved Class I molar relationship and a normal overjet and overbite. Conclusion:Palatal micro implant can be used as strong anchorage for distalizing maxillary molars without patient compliance.
