影响种植体脱落的因素分析和探讨

Analysis and discussion of factors related to dental implant failure

目的:分析影响口腔种植体脱落的相关因素,为临床提高种植修复成功率提供依据并为口腔种植医生提供参考。方法:收集2015年10月至2017年10月在内蒙古自治区人民医院口腔种植中心的患者病例497例,种植体脱落患者11例为研究对象,对种植体植入后出现了松动、脱落的原因进行分析和探讨。结果:统计期间种植手术497例(783枚种植体),种植脱落患者11例(12枚种植体),种植早期失败病例多于晚期失败(P<0.05);种植失败位点后牙区多于前牙区(P<0.05),尤其上颌后牙区多见;患者的年龄、性别对种植体脱落也有影响(P<0.05)。结论:种植体脱落可能是由于种植体植入角度偏差、过早的承担负荷力等其他多种因素导致。

Objective:To analyze and discuss the factors of implantation failure,there is an important significance to provide the basis for improving the success rate of implantation and provide clinical guidance for dentist.Methods:From October 2015 to October 2017,497 implant cases were collected in the implantation center of Inner Mongolia Autonomous Region People’s Hospital.11 cases of implantation failure including infections,loosening and falling were reviewed.Clinical manifestations were analyzed and discussion.Results:During the statistical period,497 cases(783 implants)were implanted,11 cases(12 implants)were failure,early failure of implantation is more than late failure(P<0.05),and the failure of implants were more frequent in the posterior,especially in the maxillary posterior region(P<0.05).The age and sex of the patient also had an effect on the implantation failure(P<0.05).Conclusions:The main factors of implant abscission may be angle deviation,premature loading and multiple factors.
