The All-on-4 implant is a technique that allows a fixed bridge to be fitted onto 4 dental implants in one day. Normally, a patient would need to have six to ten dental implants in order to replace all missing teeth (in either jaw), and sometimes would even require adding artificial bone.
However, in this procedure, only 4 implants are placed in specific angles, to allow the surgeon to use longer implants, and hence provide greater stability. An immediate temporary bridge is then screwed into the implants. The procedure is therefore known as ‘Same Day Teeth’ as the patients who arrived in the morning, can walk out in the afternoon with a new set of fixed teeth.
