Abstract
A dental stone casting mold adapted to a single casting process for the preparation of a positive tooth replica, the mold having opposed side walls, end walls and a floor forming a cavity for containing fluid or set dental stone, a pair of cooperating interlocking mechanisms, one of the mechanisms being carried by the mold floor and the other being adapted for fixation to the dental stone, each mechanism being cooperatively configured with respect to the other such that when they are forced toward a mating position, vector forces are created tending to urge the set dental stone toward the mold floor.
