Biomechanical intercurrence in fixed total prosthesis on implants

Abstract

It is known that the fixed total denture on implant, also known as a protocol, is a modern solution for the oral rehabilitation of patients who have lost teeth in one or two arches, and like any prosthesis, it can present complications in the different phases of its implantation, from planning and making, to inadequate fixation. As it is an implant- supported prosthesis, its success depends entirely on a successful implant, which allows for the fixation and rehabilitation expected by both the patient and the professional. The present work, gathered the main biomechanical complications in prosthesis protocol over implant, evaluating the most common failures, through bibliographic review and electronic search of current scientific articles, which proved the main complications through real and reliable results, so that they will contribute to minimize its routine occurrence. As a result, we can observe that screw loosening is the main mechanical failure, being responsible for several other complications, including fractures and bacterial infection, the main biological one mentioned, due to bacterial plaque, being most often related to poor hygiene oral. In conclusion, the protocol prosthesis is one of the best choices at the moment, and its fiaws can be consciously corrected, through adequate planning and a precise ft between the implant base and the prosthetic abutment.
