The aim of this study was to identify systemic and local risk indicators associated with peri-implantitis.
One hundred eighty-three patients treated with 916 osseointegrated titanium implants, in function for at least 1 year, were included in the present study. The implants were installed at the Foundation for Scientific and Technological Development of Dentistry (FUNDECTO) - University of Sao Paulo (USP) - from 1998 to 2012. Factors related to patient's systemic conditions (heart disorders, hypertension, smoking habits, alcoholism, liver disorders, hepatitis, gastrointestinal disease, diabetes mellitus I and II, hyperthyroidism or hypothyroidism, radiation therapy, chemotherapy, menopause, osteoporosis, active periodontal disease, history of periodontal disease and bruxism), implant's characteristics (location, diameter, length, connection, shape, and antagonist), and clinical parameters (wear facets, periodontal status on the adjacent tooth, plaque accumulation on the adjacent tooth, modified plaque index, sulcus bleeding index, probing depth, bleeding on probing, width of keratinized tissue and marginal recession).
An increased risk of 2.2 times for history of periodontal disease (PD), 3.6 times for cemented restorations compared to screw-retained prostheses, 2.4 times when wear facets were displayed on the prosthetic crown and 16.1 times for total rehabilitations when compared to single rehabilitations were found. Logistic regression analysis did not show any association between the implant's characteristics and peri-implantitis.
A history of periodontal disease, cemented prostheses, presences of wear facets on the prosthetic crown and full mouth rehabilitations were identified as risk indicators for peri-implantitis. Implants' characteristics were not related to the presence of peri-implantitis.
本研究旨在确定与种植体周围炎相关的全身和局部风险指标。
本研究纳入了183例接受916枚骨结合钛种植体治疗且至少使用1年的患者。这些种植体于1998年至2012年安装在圣保罗大学牙科学技术发展基金会（FUNDECTO）。研究因素包括患者的全身状况（心脏病、高血压、吸烟习惯、酗酒、肝脏疾病、肝炎、胃肠道疾病、I型和II型糖尿病、甲状腺功能亢进或减退、放射治疗、化疗、更年期、骨质疏松症、活动性牙周病、牙周病病史和磨牙症）、种植体的特征（位置、直径、长度、连接方式、形状和对颌牙）以及临床参数（磨损面、邻牙牙周状况、邻牙菌斑堆积、改良菌斑指数、龈沟出血指数、探诊深度、探诊出血、角化组织宽度和边缘退缩）。
发现牙周病病史的风险增加2.2倍，与螺丝固位假体相比，粘结修复体的风险增加3.6倍，修复冠出现磨损面时风险增加2.4倍，与单颗修复相比，全口修复的风险增加16.1倍。逻辑回归分析未显示种植体特征与种植体周围炎之间存在任何关联。
牙周病病史、粘结式假体、修复冠存在磨损面和全口修复被确定为种植体周围炎的风险指标。种植体特征与种植体周围炎的发生无关。
