摘　　要：目的探讨并分析影响微螺钉种植体成功率的风险因素。方法选择固定矫治患者167例,总计植入微螺钉种植体360颗。应用Logistic回归分析对15个临床变量(性别、年龄、垂直骨面型、矢状骨面型、口腔卫生、上下颌骨、左右侧、区域、附着龈宽度、品牌、长度、直径、医生、植入和加载方式)进行回归分析。结果 360颗微螺钉种植体有34颗发生松脱失败,成功率90.56%。成功率与患者的年龄、口腔卫生、垂直骨面型、植入部位(上下颌骨)、左右侧和附着龈宽度有相关性(P<0.05),与患者的性别、矢状骨面型、唇腭侧位置、医生、植入方式、加载方式、品牌、直径和长度无相关性。结论为了获得更高的微螺钉种植体成功率,医生应对患者加强口腔卫生宣教,并针对不同的风险因素采取相应的措施予以规避。Objective To investigate and analyze the risk factors associated with the success rate of miniscrew implants.Methods 167 patients（71 male patients and 96 female patients,the average age was 17.56±9.39） with a total of 360 miniscrew implants were involved in this study,and 15 clinical variables（gender,age,vertical/sagittal skeletal facial pattern,oral hygiene,the implant site,left and right side,location,and attached gingiva,brands,length,diameter,surgeons,drilling/loading patterns） were investigated by logistic regression analysis.Results 34 miniscrew implants failed and the success rate was 90.56%.The success rate was correlated with age,oral hygiene,vertical skeletal facial pattern,the implant site （upper and lower jaw）,left and right side,and attached gingiva width （P〈0.05）.No evidence was found in this study that gender,sagittal skeletal facial pattern,buccal/lingual sites,surgeons,drilling/loading patterns,brands,length or diameter was associated with the success rate.Conclusion To minimize failure,clinicians should strengthen the oral hygiene instruction and take appropriate measures for different risk factors.
