目的：重点研究和探讨微型种植体支抗在成人口腔正畸中的临床应用以及效果。方法：利用回顾性分析的方法研究和比较对我院于2010年1月1日-2012年12月31日期间收治的144例口腔正畸患者的临床资料进行回顾性对照分析，将其随机分为对照组和观察组。对照组72例患者采用非种植体强支抗疗法，观察组72例患者采用微型种植体支抗疗法，观察比较两组患者的临床效果。结果：经口腔正畸后，观察组患者疗效显著，微型种植体保持稳定状态，显效49例（68．05％），有效17例（23．61％），无效6例（8．33％），总有效率为91．67％，对照组患者显效29例（40．28％），有效30例（41．67％），无效13例（18．06％），总有效率为81．94％％。观察组总有效率明显高于对照组（P＜0．05）。观察组的各项指标明显优于对照组（P＜0．05）。结论：微型种植体支抗操作简便，安全性、可靠性好，能够显著提高正畸的临床效果，值得临床借鉴使用。“,”Objective :Focus on research and study in adults micro implant anchorage in orthodontic clinical applications and results . Methods :Retrospective analysis methods and comparative studies in our hospital in January 1 ,2010 -2012 on December 31 of the 144 cases treated orthodontic clinical data were analyzed retrospectively ,it randomly divided for the control group and observation group .Control group ,72 patients with non -implant anchorage strong therapy ,group of 72 patients was observed using micro -implant anchorage therapy , observe the clinical effects of two groups were compared .Results :Orthodontics ,the observation group were significant effect ,miniature im-plants remain stable ,effective in 49 cases (68 .05% ) ,effective in 17 cases (23 .61% ) ,6 cases (8 .33% ) ,total effective rate was 91 .67 % in the control group were cured ,29 cases (40 .28% ) ,effective 30 cases (41 .67% ) ,ineffective in 13 cases (18 .06% ) ,total effective rate was 81 . 94% % .Observation group was significantly higher (P <0 .05) .The indicators observation group than the control group (P <0 .05) .Con-clusion :Micro -implant anchorage easy operation ,safety ,reliability ,can significantly improve the clinical effects of orthodontic worthy of clinical learning to use .
