Laboratory Phase
Utilizing a laboratory putty index, the screw-retained maxillary denture
teeth arrangement was reproduced with GC resin, GC America, incorporating cast to abutment sleeves. Afterward, individual crown preparations were made on the pattern as well as a cut back of the gingival
area. Utilizing a ceramogold alloy, the framework was cast in sections,
and laser welded. Fourteen Monolithic emax crowns, Ivoclar, were fabricated in 2- and 3-unit sections. A customized Gradia, GC America,
composite gingival veneer was applied to the framework. The emax
splints were luted to the metal crown preparations with Mulitlink resin
cement, lvoclar. A permanent cement was utilized because the crowns
did not obstruct access to the screws retaining the metal framework.
