Abstract:
A method of forming a bond between a solid metal coping composed substantially of gold and/or having a solid surface layer of a gold composition and a superstructure of a a polymeric veneering or ceramic material comprising the steps of: coating the metal coping with a dental bonding material composition comprising high fusing temperature precious metal particles and low fusing temperature precious metal particles with the content of said high fusing temperature metal particles being between Â½% to 20% by weight and with the remainder of said metal particles being low fusing temperature metal particles, heat treating the coated metal coping at a temperature below the melting temperature of the high fusing temperature metal particles and high enough to cause a partial melting of the low fusing temperature metal particles, and coating the heat treated surface with a polymer based veneering material or ceramic to form an essentially unbreakable bond.
