ABSTRACT:
A method and apparatus for producing data for making dental prostheses, wherein the data can be produced on the basis of a model (2) which comprises individual segments (3a,3b,3c,. . . ), such as representing a tooth, a preparation, a gingival area, a tooth gap or a small group of teeth, from different directions in space, and a storing device for storing the shape data obtained thereby, and—second shape data (12) of only the one segment (3a,3b,3c,. . . ), only part of the segment (3a,3b,3c,. . . ) being scanned, and the segment (3a,3b,3c,. . . ) being arranged in a fixed orientation relative to a reference, and b) a comparing device for comparing the first and second shape data (1, 12) to determine the orientation of the first shape data (1) relative to the reference.
