1. A method for determining a total data set of a chewing organ, or an area thereof, the method comprising: providing a first sensor, providing at least two second sensors arranged in a fixed relation, carrying out first partial scans of the chewing organ, or the area thereof, using the first sensor, to measure partially overlapping areas of the chewing organ, or the area thereof, carrying out second partial scans of the chewing organ using the at least two second sensors, calculating the total data set of the chewing organ, or the area thereof, from individual data sets from the first partial scans, and either (a) correcting the total data set using the second partial scans, or (b) correcting individual data sets from the first partial scans using the second partial scans to produce corrected first partial scans, and generating the total data set of the chewing organ, or the area thereof, from the corrected first partial scans.
