目的本研究的目的是评估种植体的长期效果，以种植体存活和种植体成功作为结果变量。方法选取1990 ~ 1997年间接受Straumann种植体系统治疗的76例患者，共162例种植体，其中55例患者共131例种植体，在种植体放置10 ~ 16年后进行召回，进行完整的临床和影像学检查，并进行满意度问卷调查。对每次植入物的生物和技术并发症发生率进行了仔细分析。成功的定义是在整个观察期内没有所有这些并发症。分析每个种植体周围病变的相关因素。结果16年种植体长期累积成活率为82.94%。生物并发症发生率为16.94%，技术并发症发生率为31.09%。在10-16年的观察期后，累积并发症发生率为48.03%，这意味着种植体放置后需要大量的椅子时间。大部分种植体损失和生物并发症集中在相对少数的患者身上。结论尽管长期生存率较高，但生物和技术并发症较多。有牙周炎病史的患者比没有牙周炎病史的患者种植体存活率低，并且更容易发生生物并发症，如种植体周围粘膜炎和种植体周围炎。引用本文：Simonis P， Dufour T, Tenenbaum H.种植体的长期生存和成功：非浸没种植体的10-16年随访。口服Impl。Res. 21, 2010；772 - 777 . doi: 10.1111 / j.1600-0501.2010.01912.x。
ObjectivesThe aim of the present study was to evaluate the long-term results of dental implants using implant survival and implant success as outcome variables.MethodsOf the 76 patients who received 162 implants of the Straumann Dental Implant System during the years 1990-1997, 55 patients with 131 implants were recalled 10-16 years after implant placement for a complete clinical and radiographic examination, followed by a questionnaire that examined the degree of satisfaction. The incidence of biological and technical complications has been carefully analysed for each implant. Success was defined as being free of all these complications over the entire observation period. Associated factors related to peri-implant lesions were analysed for each implant.ResultsThe long-term implant cumulative survival rate up to 16 years was 82.94%. The prevalence of biological complications was 16.94% and the prevalence of technical complications was 31.09%. The cumulative complication rate after an observation period of 10-16 years was 48.03%, which meant that substantial amounts of chair time were necessary following implant placement. The majority of implant losses and biological complications were concentrated in a relatively small number of patients.ConclusionDespite a relatively high long-term survival rate, biological and technical complications were frequent. Patients with a history of periodontitis may have lower implant survival rates than patients without a history of periodontitis and were more prone to biological complications such as peri-implant mucositis and peri-implantitis.To cite this article:Simonis P, Dufour T, Tenenbaum H.
