Abstract:
The invention relates to a blank for the production of a dental shaped body, wherein the blank has a corpus (2) of tooth restoration material, from which the shaped part to be fabricated is carved by means of a tool (4) by removal of material. The blank has coding means (1) formed on part of the surface (6) of the blank corpus (2), which coding means (1) has at least one structure (8, 9) for identification of the blank. The coding means (1) consists of a plurality of panels (5.1) at the level of the surface (6) of the corpus (2) and a plurality of panels (5.2, 5.3) incorporating a flat structure (8, 9) at a level (h1, h2) which is distinguishable from at least the level of the surface (6) of the corpus (2).The invention further relates to a method for identifying a blank with the aid of coding means (1).
