To minimize potential problems during the restorative phase, it is imperative that the dentist restoring the implants, after consultation with appropriate specialists, be primarily responsible for the treatment planning. This is a challenging responsibility, especially in light of the lack of rigorous scientific principles to guide a practitioner with prosthesis design and the catastrophic nature of implant failure.To reduce the risk of this failure, a comprehensive pretreatment diagnostic work-up, including defining the prosthetic goal with the aid of a wax-up or set-up and the associated ideal, prosthetic-oriented three-dimensional implant position, is crucial. Furthermore, selection of the ideal type of prosthesis, including the respective implant components and materials, is important for the clinical long-term success of the reconstruction.An implant-supported restoration offers a predictable treatment for tooth replacement.This book offers an in depth description of variousimplant failures and its management which is of utmost importance to a dental practitioner.
