All-on-4® Treatment Concept in a Severely Resorbed Jaw Using Narrow-Platform Implants: A Case Report

Although many approaches to the restoration of edentulous maxillae and mandibles have been developed, these treatments can be costly and time-consuming, and involve extensive grafting of the edentulous ridges. The All-on-4® treatment concept has been shown to be a viable alternative, with limited grafting required, using at least four regular-platform implants to support an acrylic, screw-retained provisional prosthesis before the fabrication of a definitive prosthesis. This case presentation will discuss the use of narrow-platform (3.5-mm) implants to provide a patient with a screw-retained acrylic provisional on the day of implant placement.
