Reabilitação mandibular total fixa sobre quatro implantes all on four

Abstract

The fixed oral rehabilitation of edentulous ridges has been supported by the literature and successfully used in everyday practice. However, professionals are challenged daily to seek new treatment options, because there are still some limitations in rehabilitation treatment. In some cases of edentulous patients, treatment with implant-supported prosthesis it is almost impossible without complex techniques such as nerve transposition and grafting in the posterior maxilla and mandible. A technique described in the literature that has been used very successfully is called the All-on-four. It consists of the insertion of four implants, and the inclined distal and loading with immediate loading. Allowing the placement of longer implants, Improving support prosthetic arm less "cantilevered" distance inter implant and anchoring in the bone. The aim of this study is to make a literature review on the All-on-four system rehabilitation with immediate loading in edentulous jaws, evaluating whether this is a safe and feasible technique.
