## Overview

The term All-on-4, also known as All-on-Four and All-in-Four, refers to 'all' teeth being supported 'on four' dental implants. The name All-on-4 is a registered trademark of Nobel Biocare, used globally for both dental products and services. The treatment concept is a prosthodontics procedure for total rehabilitation of the edentulous (toothless) patient, or for patients with badly broken down teeth, decayed teeth, or compromised teeth due to gum disease. It consists of the rehabilitation of either edentulous or dentate maxilla and / or mandible with fixed prosthesis by placing four implants in the anterior maxilla, where bone density is higher. The four implants support a fixed prosthesis with 10 to 14 teeth, and it is placed immediately, typically within 24 hours of surgery.

## Alternative treatments

- **All-on-6** — Two additional implants distribute load better in patients with strong bite forces; higher cost.
- **Individual implants per tooth** — Best for partial edentulism; significantly higher cost than full-arch fixed prosthesis.
- **Conventional full denture** — Lowest-cost option for full-arch tooth loss; removable, lower bite force.
