All-on-four implants

The term All-on-four, also referred to as All‐in‐Four refers to ‘all’ teeth being supported ‘on four’ dental implants, a prosthodontics procedure for total rehabilitation of an edentulous patient, or for patients with badly broken down teeth or decayed 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.
