The dental bonding material of the present invention comprises a composition of precious metal particles consisting essentially of high fusing temperature metal particles having a melting temperature above at least about 1200° C. in a size range between 1 micron and 150 microns and low fusing temperature metal particles having a melting temperature below about 1080° C. with or without a suitable carrier for coating or brushing the dental bonding material upon the surface of a metal framework or coping. The dental bonding material may further include a conventional flux preferably containing the element boron in a concentration of between 0 and 5% by weight of the dental material. It is essential to heat treat the bonding-material after it is coated on the metal surface 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 but not a complete melting thereof.
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:
