Patent ID: 7623693

Claim:
A method for producing data for making dental prostheses, wherein the data are produced on the basis of a model ( 2 ) which comprises individual segments located in different areas, each area comprising an individual segment, comprising the steps of: a) determining with a scanning device first shape data ( 1 ) of an individual segment ( 3 a , 3 b , 3 c , . . . ), by scanning this individual segment ( 3 a , 3 b , 3 c ) from different directions in space, the resulting shape data being stored; b) determining with the scanning device second shape data ( 12 ) of this individual segment ( 3 a , 3 b , 3 c , . . . ), wherein only part of this individual segment ( 3 a , 3 b , 3 c , . . . ) is scanned, and wherein this individual segment ( 3 a , 3 b , 3 c , . . . ) is arranged in a fixed orientation relative to a reference; and c) comparing by a comparing device the first and second shape data ( 12 ) to determine the orientation of the first shape data ( 1 ) relative to the reference, wherein a two-dimensional top view on the model ( 2 ) is recorded with a camera ( 5 ) and the position of the different areas is determined on the basis thereof, each of the areas comprising a segment, and angles α, β indicative of the position of each area being stored.
