Dental Trauma and Treatments

Many factors are attributed to failure of the dental implant, either directly or indirectly. The focus of this article is to define the causation of dental implant failure, as well as to present an evaluation of the implant literature regarding etiology, classification, management, and treatment of implant failures. This article will highlight the initial signs of implant failure with a view of some clinical cases in terms of classification and degrees of implant failure. Finally, a dental implant failure checklist is formulated to guide the practitioner in defining the cause of implant failure, be it infective or noninfective, and to establish percentages and frequency of occurrence. The checklist applies to all implant systems and will help to determine the factors responsible for causation and the repair procedures, whether they are at the surgical or restorative phases. The definition of implant failure is set forth in terms of ailing, failing, failed, and surviving implants, and the appropriate treatments and dispositions are outlined.
