To evaluate the long-term clinical results of and risk factors for immediate-loading implant treatment of completely edentulous mandibles.
We retrospectively studied 220 implants in 52 patients who received immediate-loading implants in fully edentulous mandibles. Kaplan-Meier survival analyses, log-rank tests, and multilevel mixed-effects parametric survival analysis was used for statistical analyses.
Thirteen of implants in seven patients failed, and the 10-year cumulative implant survival rate was 93.9 % and significantly (p=0.049) higher in women than in men. None of the predictor variables were significantly associated with implant survival, although sex tended to be associated with implant survival.
Immediate-loading implant treatment for completely edentulous mandibles had acceptable clinical results in the long term. Although we could not identify significant risk factors, we established a multilevel mixed-effects parametric survival analysis with the immediate-loading implant survival data.
评估全下颌无牙颌即刻种植修复的长期临床效果及影响因素。
本研究回顾性分析了 52 例全下颌无牙颌患者共 220 枚种植体即刻负载的临床资料。采用 Kaplan-Meier 生存分析、Log-rank 检验和多级混合效应参数生存分析进行统计学分析。
7 例患者的 13 枚种植体失败，10 年累积种植体生存率为 93.9%，女性显著高于男性（p=0.049）。虽然性别与种植体生存率有一定的相关性，但各预测变量与种植体生存率均无显著相关性。
全下颌无牙颌即刻种植修复长期临床效果可接受。尽管我们没有发现明显的危险因素，但我们建立了一个包含即刻负载种植体生存数据的多级混合效应参数生存分析模型。
