ABSTRACT:
Dies for posteriors and anterior curves. A spherical surface is formed in the end of a body member, the side walls of which are compressed to change the spherical surface geometry to toric shape. The side wall is cylindrical and provided with two elongated slots which define two opposite ribs. A bolt passing through the ribs is tightened to provide the compressive forces.
