Process for producing a dental restoration

Claim 2

Process for producing a dental restoration which comprises: (a) applying to a surface of a cleaned nickel-containing metal core a coating of a composition that consists of powdered aluminum and an inert volatile organic liquid carrier; (b) baking the coated metal core in a substantially inert atmosphere to a temperature and for a period of time sufficient to form a continuous layer consisting of nickel aluminide on said surface; (c) cleaning the coated and based surface; and (d) applying porcelain to the baked and cleaned surface and firing.

Claim 3

The process of claim 1 wherein said carrier is propylene glycol.

Claim 4

The process of claim 1 wherein said inert atmosphere is a vacuum.

Claim 5

The process of claim 2 wherein said inert atmosphere is a vacuum.

Claim 6

A dental restoration which comprises a nickel-containing metal core having a porcelain coating, wherein the porcelain is bonded to the metal core through a continuous layer consisting of nickel aluminide.

Claim 7

A dental restoration which comprises a nickel-containing metal core having a porcelain coating, wherein the porcelain is bonded to the metal core through a continuous layer consisting of nickel aluminide.

Claim 8

Process for producing a dental restoration which comprises: (a) applying to a surface of a cleaned nickel-containing metal core a coating of a composition that consists of powdered aluminum, a thixotropic agent in an amount of less than 1 weight percent, based on weight of powdered aluminum, and an inert volatile organic liquid carrier; (b) baking the coated metal core in a substantially inert atmosphere to a temperature and for a period of time sufficient to form a continuous layer consisting of nickel aluminide on said surface; (c) cleaning the coated and based surface; and (d) applying porcelain to the baked and cleaned surface and firing.
