ABSTRACT:
A moldable dental composition for use in forming or repairing dental restorations composed of a mixture of high- and low-fusing temperature metal particles and a wax in a concentration of between thirty to eighty percent by volume of the mixture. The average particle size of the metal particles are above one micron, with the high-fusing temperature metal particles at least twice the size of the low-fusing metal particles. The composition is heat treated at a temperature to melt the low-fusing temperature metal particles and to eliminate the wax, leaving a porous metal structure with a void volume above thirty percent. The voids are filled using a filler material of metal or ceramic.
