<p>The method involves producing a dental prosthetic (5) from a blank (1) that comprises at least two regions of different characteristics selected from the group consisting of the properties rigidity, material density, translucence, porosity, or a combination of two or more of these properties. The regions are displayed on a CAD/CAM system (14) separately together with a reproduction of the prosthetic item. The reproduction of the prosthetic item (5) is displayed as a diagram, a contour, a sectional model, part of a surface, a side view, or a silhouette. The position of the reproduction can be changed relatively to the regions by input means, and the machining schedule is adjusted or generated taking into consideration the position of the reproduction of the prosthetic item. Calorimetric measurement is performed in the restoration area of the prosthetic item to be produced, and based on this measurement, a blank comprising differently colored regions is automatically preselected. In this way the position, within the blank, of the prosthetic item to be carved from the blank can be checked and adjusted.</p> |
