All-on-4 is a dental implant procedure that can replace all your upper and/or lower teeth with only four artificial roots instead of one implant for each tooth. This method of dental implants makes the procedure itself and the follow-up easier. Patients who replace their dentures with All-on-4 dental implants can care for their teeth as they would for natural teeth, by brushing and flossing. Unlike dentures, All-on-4 implants are permanent, so they stay in your mouth and attached to your gums. Traditional dental implants use one screw to anchor each individual tooth, but all-on-4 dental implants use only four screws to anchor all of your teeth. Using only four artificial roots instead of one per tooth makes the procedure itself less invasive. In addition, patients who were not candidates for dental implants because of insufficient bone density to support an implant may benefit from this option.
All-on-4s are typically supported by four to six dental implants and this procedure is considered the best treatment option for edentulous individuals.
