Abstract:
A dental milling tool and corresponding method is provided. The dental milling tool includes a ball head portion which is rounded in a semispherical manner and which, at its largest outer diameter, approximately 1-4 mm, transitions into an axial cutting portion that runs in the axial direction with said diameter at the outer circumference in a constant manner, the axial cutting portion being adjoined by a shaft portion which extends axially with a larger or at least equally large shaft diameter. A milling method for producing dental prosthesis parts is provided wherein a dental prosthesis white body which is to be sintered into the completed dental prosthesis part is milled out of a pre-sintered ceramic white body, in particular a zirconium dioxide white body, on a multi-axis CNC milling machine with a milling tool according to one of the preceding claims using 3D freeform milling process along generated travel paths.
