[Comparative studies of measuring methods for the six-dimensional recording of spatial mandibular movements].

A catalog of criteria has been developed for testing and judging methods to record extensive movements of the mandible. The aim is to find a method that functions in all six dimensions (translation and rotation) and precludes system errors. Two methods that seem to be in principle able to fulfil the criteria have been tested with calibration sets. The catalog, the results of the survey and developments to improve these methods are presented.
