The All on 4 procedure is a surgical and restorative protocol where all the teeth in one arch are supported by four dental implants. This treatment option can be used in both the upper and lower jaws. Usually, two dental implants are placed toward the front of the mouth and 2 dental implants are placed towards the back of the mouth. The posterior implants are often angled to avoid either the sinuses or the nerves.
The All on 4 procedure is versatile in that it can be used if the teeth have been removed or if the teeth are still present. In some situations, the teeth can be removed, the implants inserted and the artificial teeth screwed in during the same day!
A fully fixed restoration supported by 4, 5 or 6 dental implants is the closest substitute for real teeth that dentistry is able to offer today. The teeth are screwed into the implants and can only be removed by a dentist.
