Abstract: The invention relates a blank for producing a dental prosthesis (tooth crown) comprising a mechanically processable material block (10) and a holder (11) connected thereto for clamping in an automatic processing tool. Said block (10) is provided with a sub-gingival anatomic implant connecting part (14) which is protrusively arranged thereon and in which an implant fixture for fixing it to the implant head is formed. The holder (11) is arranged on the surface (12) of the block (10) arrangement side and the implant fixture to a surface (13) on the implant side, thereby making it possible to work the blank by means of a computer-controlled conventional tool.
