An overview of the All-on-4™ implant philosophy

Abstract

The All-on-4™ implant approach for rehabilitation of edentulous jaws was developed at the Maló Clinic in the 1990s. Based on a concept of supporting a complete edentulous rehabilitation with four implants in immediate function, it was possible to resolve clinical situations that otherwise would need more complex/more expensive procedures. The concept underwent continuous development from standard to extra-maxillary approaches, and its clinical documentation proved that it can be considered a viable treatment option for rehabilitating edentulous jaws. This article features the presentation of the concept, the inclusion/exclusion criteria and concept applications, clinical data, complications, remedies and challenges that will provide a general understanding of the All-on-4™ philosophy.
