The dental application of electroformed pure gold. II. A. Porcelain inlay. B. Cast copings with adaptable electroformed gold margins.

A technique for electroforming pure gold margins on the abutment castings of bridge substructures made from gold alloys or base metals alloys has been described. The margin of gold can be burnished to compensate for errors inherent in the production of these castings and ceramic procedures. A modification of this procedure permits marginal adjustment to completed crowns and bridges with deficient margins.
