The aim of the present paper was to present medium- and long-term data on implant survival and on the prevalence of peri-implantitis in a cohort of patients treated with full-arch rehabilitations.
Clinical records of all patients treated with immediately loaded full-arch rehabilitation in the Dental Clinic of the IRCCS Istituto Ortopedico Galeazzi in Milan, Italy, supported by moderately rough implants were retrospectively examined to calculate survival curves for implant loss and for the occurrence of peri-implantitis (both at implant- and at patient level). Regression methods were used to evaluate the correlation between the presence of periodontitis and smoking habits with the outcomes.
A total of 384 implants placed in 77 patients (96 rehabilitations) were evaluated for a mean period of 8.0 years (range 1.0-13.7 years) from loading. After 10 years, the cumulative survival rate was 96.11% (95% CI: 99.17%-93.05%; 84 implants) while the cumulative rate of implants free from peri-implantitis was 86.92% (95% CI: 82.14%, 91.71%; 60.69% [95% CI: 44.19%, 77.19%] at patient level). The cumulative proportion of implants without peri-implantitis after 10 years was significantly higher in mandible (89.76%, 95% CI: 84.49%, 95.03%) than in maxilla (81.71%, 95% CI: 71.91%, 91.51%; p = 0.028). No correlation was found between periodontal and smoking status and outcomes.
The study reported high 10-year implant survival rate for full-arch rehabilitations since implant loss was relatively rare. Peri-implantitis was relatively frequent in the examined population although the number of subjects available for 10-year evaluation was limited.
本研究旨在报告接受全颌即刻负重修复的患者的种植体存活率和种植体周围炎的流行率的中-长期数据。
回顾性检查了在意大利米兰 Galeazzi 矫形研究所牙科诊所接受即刻负载全颌修复治疗、使用中度粗糙种植体支持的所有患者的临床记录，以计算种植体丢失和种植体周围炎（种植体和患者水平）的发生的存活率曲线。采用回归方法评估牙周炎和吸烟习惯与结果的相关性。
共评估了 77 名患者（96 例修复体）的 384 个种植体，从负载开始平均随访 8.0 年（范围 1.0-13.7 年）。10 年后，累积存活率为 96.11%（95%CI：99.17%-93.05%；84 个种植体），而无种植体周围炎的种植体累积发生率为 86.92%（95%CI：82.14%，91.71%；60.69%[95%CI：44.19%，77.19%]，患者水平）。10 年后，下颌无种植体周围炎的种植体累积比例明显高于上颌（89.76%，95%CI：84.49%，95.03%）（81.71%，95%CI：71.91%，91.51%；p=0.028）。牙周炎和吸烟状况与结果之间未发现相关性。
本研究报告了全颌修复的 10 年高种植体存活率，因为种植体丢失相对较少。在检查人群中，种植体周围炎相对常见，尽管可供 10 年评估的受试者数量有限。
