CAMLOG&Science – Chapter 5 IMPLANTS IN EDENTULOUS PATIENTS Implant-supported overdentures with four interforaminal implants are recommended as the standard treatment of the edentulous mandible. In the edentulous maxilla, usually additional implants are often placed in the lateral area to improve stability. When using fixed restorations, a higher number of implants is used, i.e., six in the mandible, seven in the maxilla. Numerous independent studies have been performed to evaluate different retention methods and implant numbers in edentulous patients using im- plants with a Promote ® surface.
