摘要
A method of making a dental crown (5) for a dental preparation (1) by means of a CAD-CAM system. In said method, first a model of the dental preparation is made from a refractory material under the control of the CAD-CAM system. Subsequently, at least one layer (2) of a material suitable for dental crowns is applied to the model. The layer is sintered during or after its application, and is then ground under the control of the CAD-CAM system until a predetermined shape is obtained. Finally the refractory material is removed.
