A new approach to the All-on-Four treatment concept using narrow platform NobelActive implants.

Although a number of approaches to implant-supported restoration of severely atrophic maxillae and mandibles have been developed, most of these treatments are costly and protracted. An exception is the All-on-Four concept, which uses only 4 implants to support an acrylic, screw-retained provisional prosthesis delivered on the day of implant placement, followed by a definitive prosthesis approximately 4 months later. After the introduction of a new implant design in 2008, a new protocol was developed for provisionally treating patients with severely atrophic jaws using the All-on-Four concept and 3.

A single-center retrospective analysis of 1001 consecutively placed NobelActive implants.

This single-center retrospective study evaluated the survival rates of the NobelActive implant (Nobel Biocare AB, Gothenburg, Sweden) with a tapered body design. One thousand and one implants demonstrated a cumulative survival rate of 97.4% (97.

The all-on-four immediate function treatment concept with NobelActive implants: a retrospective study.

The All-on-Four treatment concept provides patients with an immediately loaded fixed prosthesis supported by 4 implants. This single-center retrospective study evaluated the concept while using the NobelActive implant (Nobel Biocare, Gothenburg, Sweden). Seven hundred eight implants placed in 165 subjects demonstrated a cumulative survival rate of 99.
