You cannot use a single implant for multiple teeth. Each implant has the ability to hold one dental crown. Two implants are required to secure a partial bridge or a full dental bridge. To secure an upper or lower denture, four to six implants are used. Our dental implant specialists offer All-on-4 dental implants to Ancaster patients who have lost a full arch of teeth. Dental implants are a great alternative to traditional dentures in such a case.
