摘要:
The invention relates to a blank for producing dental shaped parts, comprising a blank body (1) made of tooth restoration material, from which the shaped part can be machined using a tool (11, 12, 13, 14, 15) for removing material. The aim of the invention is to enable a reliable verification or recognition of the tool fitting or of the type and state of wear of the used tool of a machine tool for the blank. To this end, the blank has at least one gauge (4, 5), whose dimensions are such that the tool present for the machining can be identified by the gauge on the basis of its outer contour. The invention also relates to a method for producing dental shaped parts with a blank body made of tooth restoration material, from which the entire shaped part can be machined in a machining device by a tool for removing material. In order to enable a reliable verification or recognition of the tool fitting or of the type and state of wear of the used tool of a machine tool for the blank, the tool selected for the machining is, before its use, verified with regard to the outer contour thereof by using at least one gauge that is placed upon the blank.
