ABSTRACT:
A dental material and method for forming, reinforcing or repairing a dental restoration comprising a combination of a high fusing temperature metal component in a major proportion and a low fusing temperature component in a minor proportion. A binder may be added to form a putty-like consistency. The dental material is molded into a predetermined shape and heat treated at a temperature which will substantially melt the low fusing metal components but below the melting temperature of the high fusing metal component for forming a porous, sponge-like mass of interconnected particles of the high fusing temperature metal component. A filler material having a low melting temperature is then added to the porous mass and the mass is again treated to form a solid mass.
