Abstract
The invention relates to a mold having split dies to be arranged in opposition about a substrate and an outer frame situated about the perimeter of the split dies, wherein the outer frame and split dies function as a wedge and move slidably so as to convert the load produced by a vertical uniaxial press into load applied from two opposing directions across the horizontal, the split dies move in such a way as to compress the titanium or titanium alloy substrate and uniformly press the side faces thereof so as to impart the required configuration to the substrate, and to artificial bone having high biological affinity produced by the mold.
