摘　　要：背景:有研究表明,与传统支抗相比,微螺钉种植体支抗可更大程度利用拔牙间隙内收前突的上颌牙齿。目的:系统评价微螺钉种植体支抗与口外支抗正畸治疗前后对上颌或双颌前突患者侧貌的变化。方法:全面检索中国期刊全文数据库、万方数据库、中文科技期刊数据库(VIP)、中国生物医学文献数据库、Cochrane library、Medline光盘数据库、PubMed数据库等有关微螺钉种植体支抗与口外支抗正畸治疗上颌或双颌前突患者的随机/半随机对照试验及前后对照试验,进行Meta分析。结果与结论:共纳入8篇文献,241例患者,其中微螺钉种植体支抗组122例,口外支抗组119例。两组在上颌基骨相对于颅部的前后向位置、上唇最凸点相对于E线的位置和鼻唇角方面差异有显著性意义(P<0.05),在下颌平面角、上中切牙倾斜度和面突角方面差异无显著性意义(P>0.85)。相对于口外支抗,微螺钉种植体支抗可更好改善上颌或双颌前突患者上颌基骨位置、上唇最凸点相对于E线位置及鼻唇角,在下颌平面角、上中切牙倾斜度和面突角方面与口外支抗无显著差异,但仍需更多高质量的随机对照研究以提供更好的依据。BACKGROUND： Several studies have shown that micro-screw implant anchorage can retract maxillary protrusion to the maximum extent based on extraction space compared with common anchorage. OBJECTIVE： To evaluate the effects of micro-screw implant anchorage and extra-oral anchorage on patients with maxillary or bimaxillary protrusion. METHODS： The CNKI, Wanfang, CSCD, CBM, Cochrane library, Medline and PubMed databases were searched. The randomized/semi-randomized controlled and the before-after controlled trials concerning micro-screw implant anchorage and extra-oral anchorage in orthodontic treatment for patients with maxillary or bimaxillary protrusion were included for Meta analysis RESULTS AND CONCLUSION： Totally six articles and 229 cases were included. Of all the cases, there were 116 cases in micro-screw implant anchorage group and 113 cases in extra-oral anchorage group. There were significant differences in SNA, UL-E Plane and NLA （P 〈 0.05）, and there were no significant differences in SN-MP, Ul-SN and G-Sn-Pg between the two groups （P 〉 0.85）. These findings suggest that compared with extra-oral anchorage, micro-screw implant anchorage can behave better in the aspects of SNA , UL-E Plane and NLA. There are significant differences in terms of SN-MP, U1 -SN and G-Sn-Pg but more qualified randomized controlled trials are required to provide better basis.
