Sobredentaduras implanto - suportadas: Métodos utilizados para obtenção de diagnóstico e prognóstico

Abstract

Through a literature review, this work presents the most frequent failures in implant suported overdentures, as well as the most common methods and criteria used to evaluate success and failures of this treatment. The objective is to state an agreement about the most effective methods to determine a good prognosis of such procedure. It analyses the high success rate for mandibular overdentures, which are considered to be a favourable alternative treatment for pacients using complete dentures, where retention and stability problems are present. Smaller success rate for maxillary overdentures should request more carefull treatment planning. As the failures are mostly related to quantity—quality bone binomial, it is important to emphasize that a criterious pre—surgical analysis for correct indication favours long term positive results.
