[Pilot study on the clinical use of instant-picture motography]

Articulator experiments using instant-picture motography (Bumann et al. 1988) have shown that the extent and form of mandibular border movements can be recorded with a coefficient of variation of less than 5% in a "model", when recorded close to the axis. Within the framework of the pilot study the reproducible accuracy of +/- 2 degrees was within the range of the adjustment accuracy of the articulators, as compared with the Meyer reference system (1986). It is not until the evaluation of a large-scale clinical study that we will know if programming individually adjustable articulators is permissible or not.
