Adapting fixed prosthodontics principles to screw-retained restorations.
Implant restorations may be visualized clinically using a provisional fixed partial denture and in the laboratory with a fully contoured waxing on the master cast. The benefits of eggshell restorations for provisional restorations are as valid in implant prostheses as in conventional restorations. A technique is presented using the plastic laboratory sleeves to provide reliable anchorage as well as protection and preservation of the abutments. A fully contoured waxing on the master cast predictably determines the most appropriate design for screw-retained restorations. When unfavorable implant placement would create compromised morphology, a retrievable auxiliary substructure is indicated.
