Correct answer: A — An FPD uses adjacent natural teeth as abutments; an implant prosthesis uses osseointegrated implants as abutments
A conventional fixed partial denture (bridge) uses adjacent natural teeth as abutments, requiring preparation (reduction) of these teeth. An implant-supported fixed prosthesis uses osseointegrated dental implants as abutments, preserving adjacent natural teeth. The main advantage of implant-supported prostheses is preservation of tooth structure (no abutment preparation). However, implants require adequate bone volume, surgical placement, and healing time. Both have excellent long-term survival rates when properly planned and maintained.
