Intraoral luting: modified prosthetic design to achieve passivity, precision of fit, and esthetics for a cement-retained, implant-supported metal-resin-fixed complete denture.

An intraoral luting technique between electroformed gold copings and a metallic framework for a cement-retained, implant-supported metal-resin-fixed complete-denture is presented. The peculiarity is the different prosthetic design with the metallic framework that was 1.5 mm shorter than the margin of the electroformed copings. As a consequence, the conventional thick prosthesis margin (electroformed copings, cement for the luting phase, framework) was modified into a thin electroformed prosthesis seal (0.3 mm) just beyond the apical limit of the esthetic material. Passive fit between the framework and the electroformed gold copings was achieved during the intraoral luting phase. The procedure was efficient and standardized and enhanced esthetics.
