The invention relates to a method for the three-dimensional determination and digitisation of a plaster- or positive-model (1), in particular for the production of replacement teeth, whereby a method with improved handling and costs and with the following steps is disclosed: clamping the plaster- or positive-model (1) in a mounting (2) with a defined orientation, irradiation of the plaster- or positive-model (1), by means of a radiation source and recording of the radiation reflected by the plaster- or positive-model (1), evaluation of the reflected radiation by a scanning unit (7) and generation of separation information, defined movement of the plaster- or positive-model (1) relative to the radiation source along an axis (y), approximately perpendicular to the direction of radiation and linking the displacement with the separation information. The invention also relates to a device for carrying out said method.
