<p>A mandibular motion reproducing device wherein a mandibular model supporting plate on which a mandibular model is fixed is deemed as a rigid plane, three points contained in this rigid plane are selected and marked, three reference points for reproduction are set each corresponding to one of the marked points and in a predetermined dimensional relationship therewith, drive means capable of shifting the individual reference points for reproduction along the coordinate axes of X, Y, Z respectively are connected therewith, the drive means have six alternative driving directions including the orthogonal X, Y and Z directions and are individually driven by inputting position coordinate information obtained from a measuring system and the resulting motions of the reference points for reproduction are synthesized for causing the rigid plate constituting the mandibular model supporting plate to undergo three-dimensional motion.</p> |
