Electroforming technology for galvanoceramic restorations.
The ceramist needs a maximum thickness of porcelain to "move light" and create the illusion of natural teeth. Galvanoceramic restorations may be used as an alternative to all ceramic restorations or ceramic restorations with cast metal substructure. Electroforming technology is used with remarkable accuracy to create a thin, yellow-gold substructure of uniform thickness. The galvanic process involves the electrolytic deposition of gold ions on a specially prepared die. Advantages of this method include a thin, warm substrate for improved esthetics, marginal integrity of 15 to 20 microns, and a simplified, economical procedure for fabricating substructures. This article describes both clinical and laboratory steps for creating galvanoceramic restoration.
