The purpose of this study was to assess tobacco use as a risk factor for early implant failure.
To address the research aim, a retrospective study design was used, and a study sample was derived from among patients who had 1 or more implants inserted between July 1996 and July 2004. The main predictor variable was the frequency of tobacco use. The major outcome variable was early implant failure. Appropriate descriptive, bivariate, and multivariate statistics were computed.
The study sample was composed of 650 patients who had 1,628 implants inserted and were selected for analysis. The early implant loss rates found in the nonsmoking group and the smoking group were 3.32% and 2.81%, respectively. Univariate and bivariate analyses showed no statistical significance for early implant losses associated with the frequency of tobacco use.
The results of this study suggest that tobacco use alone cannot be considered as a factor for risk related to early implant failures. Prospective studies are needed to assess the risk of early implant failure in conjunction with smoking.
本研究旨在评估烟草使用作为早期种植体失败的风险因素。
为实现研究目的，采用回顾性研究设计，研究样本来自1996年7月至2004年7月期间植入1枚或更多种植体的患者。主要预测变量为烟草使用频率。主要结局变量为早期种植体失败。计算了适当的描述性、双变量和多变量统计量。
研究样本由650例植入1628枚种植体并被选作分析对象的患者组成。非吸烟组和吸烟组的早期种植体丢失率分别为3.32%和2.81%。单变量和双变量分析显示，与烟草使用频率相关的早期种植体丢失无统计学意义。
本研究结果表明，仅烟草使用不能被视为与早期种植体失败相关的风险因素。需要进行前瞻性研究以评估与吸烟相关的早期种植体失败风险。
