Considering the increasing use of dental implants, their failure is a serious challenge encountered by dentists. An accurate prediction of the rate of failure based on the underlying factors allows patients to accept the risk of failure. This study assessed the failure rate and time of implant treatment in patients referred to a specialized clinic. This study was conducted on implant cases in Shahid Montazeri Clinic in Tehran, Iran, from March 2008 to March 2017. A total of 544 patients including 248 patients in the failure group (case) and 296 patients in the treatment success group (control) were evaluated. Data were analyzed using the univariate and multivariable logistic regression. Males, older patients, posterior implant placement site, and shorter height and/or diameter of dental implants increased the risk of failure (P<0.05). The implant brand was also an effective factor in the failure rate (P<0.001). Implants with smaller length or diameter were more prone to failure. Accordingly, in selecting a dental implant, attention should be paid to the patient's age, sex, and location of implant to reduce the failure rate by increasing the diameter and length of implant.
鉴于牙种植体的使用日益增加，其失败是牙医面临的一项严峻挑战。基于潜在因素准确预测失败率能让患者接受失败风险。本研究评估了转诊至一家专科诊所的患者的种植治疗失败率和时间。本研究于2008年3月至2017年3月在伊朗德黑兰的沙希德·蒙塔泽里诊所对种植病例进行。共评估了544例患者，其中失败组（病例组）248例患者，治疗成功组（对照组）296例患者。使用单变量和多变量逻辑回归分析数据。男性、老年患者、种植体后置部位以及牙种植体较短的高度和/或直径会增加失败风险（P<0.05）。种植体品牌也是失败率的一个影响因素（P<0.001）。长度或直径较小的种植体更易失败。因此，在选择牙种植体时，应注意患者的年龄、性别和种植体位置，通过增加种植体的直径和长度来降低失败率。
