背景资料：本回顾性研究旨在评估系统和局部骨和口腔内因素对种植体从基台连接到2年内丢失发生率的影响。材料和方法：从接受骨内Branemark（R）系统植入物治疗的总患者组中随机收集了700例患者的档案（Nobel Biocare，哥德堡，瑞典）在鲁汶天主教大学医院牙周病科进行。观察的终点是评估基台安装后2年种植体的丢失情况。该研究包括所有未发生早期丢失的种植体和基台手术后2年可以评估其状态的种植体，因此，分析了412名患者（240名女性）的1514个种植体的数据。对于每一位患者，都仔细检查了病史。数据收集和分析主要集中在内源性因素，如高血压、凝血问题、骨质疏松症、甲状腺功能亢进症、化疗、I型或II型糖尿病、克罗恩病、一些局部因素[如骨质和骨量、植入物（长度、直径、位置）、缺牙类型、PTV、放射治疗]、吸烟习惯和手术期间破坏无菌性。放射治疗、种植体（直径和位置）以及种植体插入和基台连接处的PTV均显著影响种植体loss.Conclusion：种植体在口腔中的位置和放射治疗似乎是解释种植体丢失的主要原因。另一方面，吸烟和全身健康因素似乎不是晚期种植体丢失的主要病因。
Background: This retrospective study was set to assess the influence of systemic and local bone and intra-oral factors on the occurrence of implant loss from abutment connection up to 2 years.Materials and methods: The files of 700 patients, have been collected randomly from the total patient group treated by means of endosseous Branemark (R) system implants (Nobel Biocare, Gothenburg, Sweden) at the Department of Periodontology of the University Hospital of the Catholic University of Leuven. The end point observation was evaluating the loss of the implants 2 years after abutment installation. The study involved all implants that did not encounter early loss and implants for which it was possible to evaluate its status 2 years after abutment surgery.Thus, data of 412 patients (240 females) provided with 1514 implants were analyzed. For each patient, the medical history was carefully checked. Data collection and analysis were mainly focused on endogenous factors such as hypertension, coagulation problems, osteoporosis, hypo- hyperthyroidism, chemotherapy, diabetes type I or II, Crohn's disease, some local factors [e.g. bone quality and quantity, implant (length, diameter, location), type of edentulism, PTV, radiotherapy], smoking habits, and breach of sterility during surgery.Results: Radiotherapy, implant (diameter and location), and higher PTV at implant insertion and abutment connection, all affected significantly the implant loss.Conclusion: Implant location in the oral cavity and radiotherapy seem predominant to explain the occurrence of implant loss. On the other hand, smoking and systemic health factors do not seem to be prominent players in the etiology of late implant loss.
