摘　　要：目的:评估种植体失败位点再种植修复治疗的临床效果及其影响因素。方法:选择2005年1月—2011年12月间就诊的失败位点再种植的患者共12例(15颗种植体),统计再植人种植体的存留情况,收集并分析影响再植入种植体存留相关危险因素的临床资料。采用SPSS13.0软件包对数据进行统计学分析。结果:首次失败位点再植入的种植体存留率为100%[(33.5±15.4)个月]。再种植时选择的平均种植体直径为(4.5±0.6)mm,大于首次种植时的(4.1±0.7)mm(P<0.05)。首次植入种植体的平均存留时间为(12.9±15.9)个月,从种植体脱落到再种植的平均间隔时间为(6.8±4.4)个月。患者自身因素、种植体因素以及手术、修复治疗因素并未对失败位点再植入种植体的存留产生影响。结论:种植失败位点可考虑再种植治疗的修复方案,种植医师对取得满意的种植体存留率应具有足够信心。PURPOSE： To evaluate the clinical outcomes as well as related factors of dental implants replaced in previously failed sites. METHODS： A total of 12 patients （15 implants） who received replacement in previously failed sites during January 2005 to December 2011 were included. Outcomes of redo-implants were collected and clinical data was recorded and analyzed regarding risk factors related to redo-implants＇ survival using SPSS13.0 software package. RESULTS： The survival rate of redo-implants was 100% [（33.5±15.4） months]. The mean redo-implant diameter （4.5± 0.6） mm was significantly larger than the previous one （4.1±0.7） mm （P〈0.05）. The mean survival time of implants placed for the first time was （12.9±15.9） months. Implant replacement occurred （6.8±4.4） months after original implant removal. No significant influence was observed on patient and implant-related factors as well as surgery and prosthesis-dependent factors. CONCLUSIONS： Reimplantation in previously failed site is considered as one of feasible prosthesis plans, and surgeons ought to get enough confidence to achieve satisfactory implant survival rates.
