Abstract: A blank for preparing artificial tooth parts, such as inlays, overlays or partial and complete crowns and bridges comprises a body of laminate material. The body has at least one layer of high abrasive resistance, at least one layer of high breaking strength, and at least one layer of lower hardness and breaking strength. For forming the tooth part, material is removed from the blank in such a way that the layer having high fracture strength forms a reinforcing structure. In a single working step, a tooth part of high strength can be machined.
