Abstract

The present invention is a method for forming, repairing or restoring a dental restoration which includes the steps of forming a base material of high-fusing temperature metal particles, low fusing temperature metal particles and a volatile binder substantially or entirely of wax; applying the base material to a non-refractory die; shaping the base material upon said die into a desired configuration; removing the shaped base material from the die; combining particles of activated carbon to a dental investment material to form a combined dental investment material having activated carbon in a concentration above at least 0.005 wt. %; investing the shaped base material with the combined dental investment material; heat treating the shaped base material in the investment at temperatures up to 1200°C to vaporize the volatile binder from the base material for forming a porous structure with a void volume of at least 20%; and filling the porous structure with a filler material to form a finished dental coping.
