Anyone in reasonable health who wants to replace missing teeth. You must have enough bone in the area of the missing teeth to provide for the anchorage of the implants. Some people are missing all their teeth and most of those are excellent candidates for dental implants, but today, we use implants to replace small bridges, removable partial dentures and even missing single teeth. If a patient does not have enough bone to support a dental implant, bone grafts can be placed.
