摘　　要：目的:观察短种植体在上下颌后牙区的成功率。方法:自2002年7月至2007年7月在山东大学口腔医院种植中心种植牙病例52例,89颗短种植体,所有的种植体由同一个有多年种植经验的外科医生操作,修复医生也有成熟的经验。观察的指标包括性别、年龄、种植系统、种植位置、修复方法。种植体成功率的分析采用生命表法(Wilcoxon test)。对于失败的种植体进行了详尽的分析。结果:所有种植体均发生骨结合并完成了上部结构修复,在1～5年的观察中,脱落种植体1枚,为上颌,累积成功率95.8%;下颌种植体无1例脱落,累积成功率为100%。结论:只要病例选择合适,短种植体在上下颌后牙区可获得和标准种植体同样的成功率。Objective：The aims of this study were to evaluate the survival rates of short dental impants in posterior areas.Methods：A total of 52 subjects received 89 short dental implants between July,2002 and July,2007.All implants were placed by one experienced surgeons,and rehabilitations were done by a experienced prosthodontists.gender factors, age factors,types of dental implants,position of dental implants and prosthetic variables on implant survival was studied.Implant survival was analyzed using a life-table analysis （Wilcoxon test）.Each implant failure was anayzed carefully.Results：All implants were osseointegrated and rahabilated.one implant in maxilla was failed after restoration in six months and no implants failed off inmandible.so the survival rates were 95.8% in maxilla and 100% in mandible.Conclusion： Treatment with short implants can be considered safe and predictable if used under strict clinical protocols,and could receive the same survival rates as the standard implans.
