The possibility of installing implants in fresh sockets was first proposed as a viable treatment option in the 1970s. Objective: to assess the relationships of subject-level and implant-level characteristics on the failure of immediate implants installed in sites that contained teeth associated or not with chronic apical periodontitis.
A retrospective study was undertaken with data from patients who received immediate implants with a minimum follow-up of 12 months after loading. The Generalized Estimating Equation, applying a multiple logistic regression model, was employed to investigate the association between predictor variables/co-variables and failure of the immediate implants.
Four hundred and twenty-three implants were installed (208 uninfected/215 infected sites) in 186 patients (92 men/96 women) with a mean age of 57.1 years old. The survival rate of implants was 91%. Approximately half (215/50.8%) of the alveoli that received immediate implants had chronic apical periodontitis associated with the extracted teeth, and 191 (88.8%) of these survived until the last follow-up visit. When the infection-free sites were analyzed, this frequency was higher (93,3%), but the presence of chronic apical periodontitis did not show statistical significance in the implant failure (=0.167). Smokers with a consumption of more than 20 cigarettes/day and short implants had more failures (OR:7.66, =0.012; OR:14.06, =0.002; respectively).
Short implants and consumption of more than 20 cigarettes/day were important predictors for failure of immediate implants, regardless of presence of chronic apical periodontitis. Osseointegration, dental implant, smokers, study, immediate dental implant loading.
在20世纪70年代首次提出在新鲜拔牙窝中植入种植体作为一种可行的治疗选择。目的：评估在包含或不包含与慢性根尖周炎相关牙齿的部位植入即刻种植体失败与个体水平和种植体水平特征之间的关系。
进行一项回顾性研究，收集接受即刻种植体植入且在加载后至少随访12个月的患者数据。采用广义估计方程，应用多元逻辑回归模型，研究预测变量/协变量与即刻种植体失败之间的关联。
186例患者（92例男性/96例女性）共植入423枚种植体（208个未感染部位/215个感染部位），平均年龄57.1岁。种植体的存活率为91%。接受即刻种植体植入的牙槽窝中约一半（215/50.8%）与拔除牙齿相关的慢性根尖周炎，其中191例（88.8%）存活至最后一次随访。在分析无感染部位时，该频率更高（93.3%），但慢性根尖周炎的存在在种植体失败方面未显示统计学意义（P=0.167）。每天吸烟超过20支的吸烟者和短种植体的失败率更高（OR：7.66，P=0.012；OR：14.06，P=0.002）。
无论是否存在慢性根尖周炎，短种植体和每天吸烟超过20支是即刻种植体失败的重要预测因素。骨结合、牙种植体、吸烟者、研究、即刻牙种植体加载。
