1. A mounting (1) for use in a digitally controlled material-ablating process, containing at least one fixed real prefabricated prosthetic tooth (3),
wherein
the mounting (1) has a plane (1.1) in which at least one flat three-dimensional moulded body (4a) is arranged, or the mounting (1) has a plane (1.1) in which at least two clamping elements (4b) are arranged, the at least one real prefabricated prosthetic tooth (3) being fixed in the moulded body (4a) or between the clamping elements (4b),
a tooth axis (3.1) of the at least one real prefabricated prosthetic tooth being arranged at an angle of 20° to 160° to the plane (1.1) of the mounting (1), so that the at least one real prefabricated prosthetic tooth (3) is processible from coronal (3.2) direction and/or from apical (3.3) direction in an ablating process,
digital or scannable correction factors (2) being assigned to the mounting (1) for spatial, real arrangement (6) of the at least one prefabricated prosthetic tooth (3) in relation to a reference arrangement comprising at least one corresponding real prefabricated reference prosthetic tooth (A3) in a real reference mounting (A1) of the mounting (1) or at least one virtual prefabricated reference prosthetic tooth (vA3), and
the digital or scannable correction factors (2) comprise information with respect to deviation in ACTUAL arrangement in the form of translation (x,y,z) data and optional rotation data of the respective real prefabricated prosthetic tooth in relation to the reference arrangement.
