Abstract:
A method for the production of a dental object (1) by grinding a blank (2) made of ceramic or a ceramic-plastic composite material, wherein, for the production of a preform (3) having an outer contour (4) that differs from a final outer contour (5) of the dental object (1) to be produced, a grinding channel (8) is machined into the blank (2) or into a pre-preform (9) already made from the blank (2), in at least one grinding process using a grinding tool (6) of a grinding device (7), wherein the outer contour (4) of the preform (3) is formed with the grinding channel (8) on one edge (10) thereof, and on the edge (11) of the grinding channel (8) opposing the outer contour (4) of the preform (3), at least one remaining piece (12) is removed from the blank (2) or from the pre-preform (9) at least in sections.
