口腔种植义齿修复失败16例原因分析

Analysis of the reason for 16 cases of dental implant failures

目的分析与探讨口腔种植修复失败的原因。方法收集2013年9月—2015年9月之内在新疆医科大学第二附属医院口腔科行种植修复患者209例,种植体356颗(失败的病例12例、共16颗种植体),进行回顾性研究并分析与探讨种植体失败的原因。结果失败种植体共16颗。两种种植系统失败的病例差异无统计学意义(P>0.05)。性别、年龄、牙位等基本信息差异无统计学意义(P>0.05)。患者自身因素中因系统性疾病失败的病例所占的比例高于其他原因、种植体因素中央螺丝松动所占的比例高于其它原因(P<0.05)。结论种植体的失败与众多因素有关,患者自身疾病,适应证选择不当、设计不合理、手术操作不规范、口腔卫生不良等是引起种植修复失败的主要原因。

Objective To analyze and discuss the causes of 16 implant denture failures.Methods Data of 209 oral implant patients （356 implants） treated from Stomatological Department of the Second Affiliated Hospital of Xinjiang Medical University from September2013 to September 2015 were chosen and data of 16 cases of failure implants were analyzed.Results There were a total of 16 cases of implant failures.There was no significant difference between the two implant systems （P〉0.05）.There was no significant difference in gender,age,tooth position and other basic information （P〉 0.05）.The proportion of systemic diseases was higher than that of other causes,the proportion of central screws loosening was higher than other causes （P〈0.05）.Conclusion The failure of the implant is related to many factors,patient＇s related diseases,inappropriate selection of indications,unreasonable design,lack of standardization of surgical technique and poor oral hygiene,which are the main causes of the failure of dental implant restoration.
