AimTo evaluate long‐term survival and success of dental implants and evaluate indicators affecting the long‐term outcome.Materials and MethodsImplant survival, success and crestal bone loss (BL) over time were evaluated. For covariates at patient level, Kaplan–Meier estimates of implant survival were compared between groups with the log‐rank test. Observed mean bone loss (MBL) was plotted as a function of time. Cumulative frequencies of BL were plotted for different post‐op times. Uni‐ and multivariate analysis was performed. Simple linear mixed and multiple linear mixed models for BL at 1, 5 and 10 years were fitted.Results407 patients (221 women, 186 men; mean age 64.86 years (range 28–92, SD 10.11)), with 1482 implants, responded. Absolute implant survival was 94.74%; MBL was 0.81 mm (SD 1.58, range 0.00–17.00) after an average follow‐up of 10.66 years (range 10–14, SD 0.87). Implant survival was influenced on implant level by smoking, implant width and early bone loss (EBL) > 0.5 mm; on patient level by a history of periodontitis. Indicators influencing MBL after the 1st year were abutment height, type of surgery and implant width, while after 5 and 10 years of function were abutment height, EBL > 0.5 mm and smoking.ConclusionImplant survival was significantly affected by a history of periodontitis on patient level and by smoking, implant width and EBL > 0.5 mm on implant level. Late bone loss was significantly affected by abutment height, EBL > 0.5 mm and smoking.Trial Registration: B670201524796

一项为期 10 年的回顾性临床研究，以确定种植体周围骨质流失和种植体失败的风险指标


目的 评价种植牙的长期生存率和成功率，并评价影响长期结局的指标。材料和方法评估种植体存活率、成功率和牙槽嵴骨丢失 （BL） 随时间的变化。对于患者水平的协变量，用对数秩检验比较各组之间植入物存活率的 Kaplan-Meier 估计值。观察到的平均骨质流失 （MBL） 绘制为时间的函数。绘制不同术后时间的 BL 累积频率。进行单变量和多变量分析。拟合 1 、 5 和 10 年 BL 的简单线性混合和多线性混合模型。结果407 名患者 （221 名女性，186 名男性;平均年龄 64.86 岁 （范围 28-92，SD 10.11）），有 1482 个植入物，有反应。种植体绝对存活率为 94.74%;平均随访 10.66 年后，MBL 为 0.81 毫米 （SD 1.58，范围 0.00-17.00） （范围 10-14，SD 0.87）。种植体存活率受吸烟、种植体宽度和早期骨质流失 （EBL） > 0.5 mm 的影响;在患者层面上有牙周炎病史。影响 1 年后 MBL 的指标是基台高度、手术类型和种植体宽度，而功能 5 年和 10 年后是基台高度、EBL > 0.5 mm 和吸烟。结论患者水平牙周炎病史、吸烟、种植体宽度和种植体水平 EBL > 0.5 mm 对种植体存活率有显著影响。基台高度、EBL > 0.5 mm 和吸烟对晚期骨质流失有显著影响。试用注册：B670201524796
