When multiple teeth are missing, teeth may be replaced with either traditionally fixed bridgework supported on the remaining teeth, or with a removable partial denture that is held in place by claps on the remaining teeth, or with implant restorations.
The benefits of implants in the case of missing multiple teeth are ever greater than those in the single tooth replacement scenario. The traditional removable partial denture tends to accelerate bone loss because of undue pressure on the gum tissue.
