Three-unit fixed prostheses versus implant-supported single crowns

Historically, three-unit FPDs have served patients well in replacing a single missing tooth. However, the three-unit FPD procedure is invasive if teeth adjacent to the space are not in need of restorations. The technique of implant placement and restoration of the missing tooth with an implant-supported crown is replacing the three-unit FPD procedure. Research appears to indicate that the single-implant procedure and implant-supported crown have greater longevity than does the FPD restoration on natural teeth. It appears that the state of the art is, whenever possible, placing a single implant-supported crown to replace a single missing tooth.
