摘要/Abstract

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), 统计再植入种植体的存留情况, 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%。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。

Abstract: 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% . 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.
