ABSTRACT Composite metal/porcelain tooth reconstruction are manufactured by bonding porcelain to a basis metal which is pretreated by electrolytically depositing thereon a thin layer of a different metal. The pretreatment has the effect of increasing the bond strength between the metal and the porcelain. If the basis metal is a noble metal, the different metal may be deposited directly, and the porcelain then bonded on. If the basis metal is a base metal the pretreatment preferably includes an etching step, deposition of a preliminary metal layer on the etched surface, Followed by deposition of the main metal layer, followed by a final deposition of metal prior to bonding to the porcelain. - 1 -
