Abstract

The invention includes a support frame for producing a dental workpiece. The frame has a Z axis and comprising wall sections defining a hole that extends along the Z axis through the frame. At least one of the wall sections comprises an adhesive-directing surface extending along the Z axis in a non-parallel relationship. Such a configuration provides optimized methods for affixing a blank to the support frame and optimized properties of the blank after fixation to the support frame.
