All-on-4 is an alternative approach to place a full arch (top or bottom set) of fixed, replacement teeth. Four dental implants are used to stabilize the replacement teeth. The All-on-4 concept involves placing implants in available bone, thereby avoiding the need for bone grafting or sinus lift. Special abutments allow a temporary set of replacement teeth to be placed the same day and used with a modified diet while gum tissues heal and the implants integrate with natural bone. After about 4-6 months, the final bridge is then placed and the patient is able to resume a normal diet.
