ABSTRACT:
A method for scanning, in connection with the production of a three-dimensional dental body, an outer contour of a rotating model with a scanning device which operates at a scanning angle relative to the rotational axis of the model, comprises mounting the model in or on a rotatable holder, supporting the model in the holder so that the contour to be scanned on the model above a preparation line is exposed to the angled scanning device, applying the scanning device towards a surface situated on the model below the preparation line, activating the holder for rotation and the scanning device for contour scanning, and activating during the contour scanning at least one of the scanning device and the holder for movement in the vertical direction of the model.
