问题的陈述。用牙科植入物替换脱落的牙齿是一种广泛的治疗方法，其相关问题也经常遇到。然而，与早期种植体失败相关的因素尚未得到很好的记录。需要进一步分析影响骨整合建立的因素，以最大限度地提高手术的可预测性，并最大限度地减少种植失败。本回顾性临床研究的目的是探讨可能的风险因素与早期种植失败之间的关系。这项回顾性临床研究评价了142名参与者，他们在2007年至2011年期间接受了276个外部连接BTI植入物。参与者变量（年龄、性别、全身性疾病、吸烟、饮酒、磨牙症和牙周病程度）、种植体变量研究了（缺牙类型、定位、面积、直径、长度和骨质）、干预变量（扩张机制、窦提升技术、骨再生和种植体插入）和术后变量（术后1周时疼痛/炎症的存在）。采用多水平logistic回归模型（混合效应型模型）确定变量对早期种植体失败的影响。早期种植失败与男性（P=.001）、严重牙周病（P=.005）、种植体短（P=.001）、扩张技术（P=.002）和术后1周疼痛/炎症（P
Statement of problem. The replacement of lost teeth with dental implants is a widespread treatment whose associated problems are also frequently encountered. Nevertheless, the factors associated with early implant failure have not been well documented. Further analyses of the factors influencing osseointegration establishment are required to maximize the predictability of the procedure and minimize implant failures.Purpose. The purpose of this retrospective clinical study was to explore the association between possible risk factors and early implant failure.Material and methods. This retrospective clinical study evaluated 142 participants who received 276 external connection BTI implants between 2007 and 2011. Participant variables (age, sex, systemic disease, tobacco use, alcohol consumption, bruxism, and degree of periodontal disease), implant variables (type of edentulism, localization, area, diameter, length, and bone quality), intervention variables (expansion mechanisms, sinus augmentation techniques, bone regeneration, and implant insertion), and postoperative variables (presence of pain/inflammation at 1 week postsurgery) were studied. A multilevel logistic regression model (mixed effects-type model) was used to determine the influence of variables on early implant failure.Results. Early implant failure was significantly associated with the male sex (P=.001), severe periodontal disease (P=.005), short implants (P=.001), expansion technique (P=.002), and postoperative pain/inflammation at 1 week postsurgery (P
