正畸用微种植钉种植成功的多因素分析
|
Abstract:
摘要 目的:探讨影响正畸支抗用微种植钉临床成功的因素。方法:选择固定正畸治疗中的种植微种植钉患者114例,微种植钉253颗。应用Logistic回归(Logistic Regression)统计方法对15个与微种植钉种植失败有关的指标(性别、年龄、垂直骨面型、矢状骨面型、植入部位、上下颌骨、软组织类型、口腔卫生状况、种植体长度和直径、植入方式、植入角度、加载时机、加载强度、临床用途)进行回归分析。结果:种植成功224颗,16例共计29颗脱落失败,种植成功率88.54%。年龄、口腔卫生情况、垂直骨面型和上下颌骨是影响微种植钉成功的独立指标(P＜0.05)。结论:为了减少正畸支抗用微种植钉的失败,要对患者加强口腔卫生的宣教和监督,特别是对年轻(尤其是<12岁)的高角患者的下颌植入时
