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.
The purpose of this retrospective clinical study was to explore the association between possible risk factors and early implant failure.
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.
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<.001).
Early dental implant failure is more frequent in men and in individuals with severe periodontal disease, short implants, pain/inflammation at 1 week postsurgery, or bone expansion treatment.
用牙种植体替代缺失牙是一种广泛应用的治疗方法，其相关问题也经常出现。然而，与早期种植体失败相关的因素尚未得到充分记录。需要进一步分析影响骨结合建立的因素，以最大限度地提高该手术的可预测性并减少种植体失败。
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体失败之间的关联。
本回顾性临床研究评估了2007年至2011年间接受276颗外部连接BTI种植体的142名参与者。研究了参与者变量（年龄、性别、全身疾病、吸烟、饮酒、磨牙症和牙周疾病程度）、种植体变量（无牙类型、位置、区域、直径、长度和骨质）、干预变量（扩张机制、鼻窦增高技术、骨再生和种植体植入）以及术后变量（术后1周疼痛/炎症的存在情况）。使用多级逻辑回归模型（混合效应型模型）来确定变量对早期种植体失败的影响。
早期种植体失败与男性（P = .001）、严重牙周疾病（P = .005）、短种植体（P = .001）、扩张技术（P = .002）以及术后1周疼痛/炎症（P < .001）显著相关。
早期牙种植体失败在男性以及患有严重牙周疾病、种植体短、术后1周疼痛/炎症或接受骨扩张治疗的个体中更为常见。
