    Abstract: The invention relates to a method for positioning a blank (1 16), which after insertion in a holder is in contact therewith, wherein the holder has a structural element. The blank (16) is positioned in the holder by means of an adapter (118), which is inserted in both the holder or the structural element and the blank, wherein the adapter positively engages with the holder or the structural element and with the blank.

    Abstract: The invention relates to a method for the production of a dental restoration from a blank, which has regions or layers of ceramic materials with differing compositions, under use of the method steps, filling of the ceramic materials into a mold, pressing of the ceramic materials to form a blank, removal of the blank from the mold, temperature treatment of the blank, wherein the ceramic materials are filling into the mold in such a way that layers and/or regions after temperature treatment have a profile that is available as a digital set. There is then a virtual contouring of the dental restoration taking shrinkage into account, a virtual representation of the blank, positioning of the virtually represented dental restoration in the virtually represented blank taking into account the material characteristics of the layers and/or regions, determination of the data for the blank which correspond to the position of the virtually arranged dental restoration or the mold in the blank, as well as transfer of the data to a machine to produce the dental restoration from the blank.
