摘要
目的:研究使用和不使用微种植体支抗矫正双颌前突的硬组织变化。方法:选取双颌前突病例12例,随机分为两组,Ⅰ组不使用微种植体支抗,Ⅱ组使用微种植体支抗。通过对两组治疗前后的头颅侧位X线片进行头影测量分析,评价微种植体支抗在双颌前突治疗中的临床效果。结果:矫正结束,两组病例面型均得到了显著改善,Ⅰ组上下颌切牙切缘分别内收3.69 mm和3.56 mm,磨牙平均前移2.36 mm,Ⅱ组上下颌切牙切缘分别内收4.93 mm和4.26 mm,磨牙平均前移1.12 mm。结论:使用微种植体支抗可以使上下前牙内收更多,取得更好的临床效果。
Objective： To study the change of hard tissue following treatment of bimaxillary protrusion using microsrew implant anchorage or not. Methods： Twelve patients with himaxillary protrusion were randomly divided into two groups. In group Ⅰ patients were not treated using microsrew implant anchorage and in group Ⅱ patients were treated using microsrew implant anchorage. The cephalometric films before and after treatment with two measures evaluated the clinical effect of bimaxillary protrusion treatment with microsrew implant anchorage. Results： All the facial profiles were improved significantly. In group Ⅰ the edge of the upper and lower incisors were retracted 3. 69mm and 3.56mm respectively, the molar moved anteriorly 2.36ram averagely. In group Ⅱ the edge of the upper and lower incisors were retracted 4.93ram and 4.26mm respectively and the molar moved anteriorly 1.12mm averagely. Conclusion： More effective clinical effect could be achieved using microsrew implant anchorage, which retracted upper and lower teeth more.
