摘　　要：目的探讨前牙桩冠脱落的危险因素。方法对123位前牙桩冠修复患者(131颗患牙)进行病例—对照研究,并用单因素和多因素非条件logistic回归模型分析,探讨前牙桩冠修复脱落的危险因素。结果最终进入logistic回归模型的因素有深覆牙合、食物嵌塞、咬合习惯、牙列缺损未修复、患牙缺损达龈下,OR值分别为7.386、8.121、7.084、13.258和15.583。结论提示以上因素可能与桩冠修复脱落的发生有关,并且是其危险因素。Objective To investigate risks factor for the post dislodgment of the maxillary anterior tooth. Methods A case- control study was performed based on 123 treated anterior teeth. Statistical analysis of univariate regression, multivariate non - conditional logistic regression were used to determine risk factors of the post dislodgment of the maxillary anterior tooth. Results Deep overbite, food impaetion, dentition defect without restoration, bitehabit, and subgingival defect were associated with the post dislodgment of the maxillary anterior tooth. The odds ratio （OR） was 7.386,8.121,7.084,13.258 and 15.583, respectively. Conclusion Results of the study suggest that deep overbite, food impaction, dentition defect without restoration, bite habit, and subgingival defect were risk factors associated with the post dislodgiugment.
