FAILURE IN IMPLANTS

Abstract

Dental implants are commonly used to replace the missing teeth in partially and completely edentulous ridges. While the overall success rate of implant dentistry is very high, dental implants seldom fail. The occurrence of implant failure is a matter of great concern for implantologists and awareness of such unavoidable fact is clinically important. The purpose of this review was to offer a critical evaluation of the literature and to provide the clinician with scientifically-based diagnostic criteria for monitoring the implant condition. Aetiologies and factors associated with implant failure should be elucidated for further improvement of the treatment outcome. This information may be necessary to develop effective strategies for treatment and prevention. Therefore, the aim of this paper is to provide an insight into different aspects of implant failures by highlighting various classifications put forward by different authors Key Words : Classification, Osseointegration, Implant failures.
