Abstract:
A method for forming a dental coping comprising the steps of: forming a first sheet composed of a base material composition containing high fusing temperature metal particles and a wax binder; forming a second sheet of a filler material composition containing low fusing temperature metal particles and a wax binder, superimposing the two sheets to form a laminate, molding the sheets either separately or as a laminate over the surface of a die into the shape of a tooth to be restored, placing the molded laminate into a furnace and and performing a single heat treatment operation by raising the temperature in the furnace from a temperature substantially below the melting temperature of the low temperature fusing particles to a maximum temperature not to exceed about 1130Â° C. until a densified coping is formed.
