Abstract

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. © 2025 Elsevier B.V., All rights reserved.
