A multifunctional, provisional, implant-retained fixed partial denture

This article describes the modification of a procedure for fabricating a la boratory-processed, metal-reinforced, acrylic resin provisional restoration that becomes an implant-retained fixed partial denture. The modification i nvolves the incorporation of patrix and matrix components into a cast metal framework. The prosthesis can be used as an alternative to a removable rad iologic stent and surgical guide. It can function as a surgical guide durin g implant placement and help retract the buccal mucogingival nap during imp lant placement. The prosthesis also can be used as an aid in locating the i mplant during stage II surgery. Finally, the pontics can be converted into an implant-supported provisional restoration immediately after the implant prosthetic components are attached to the uncovered implants.
