Abstract
Disclosed herein is a device for the representation of condylar movements of a patient and their correct simulation which includes models of sets of teeth to determine the required corrections to the biting surfaces in order to obtain ideal occlusion. The device includes an articulator with the lower part thereof able to be brought into a predetermined three-dimensional relation with respect to an upper part of the articulator and having two blocks having guide elements on the lower part of the articulator to support condyle balls of the upper part of the articulator. The device further includes a lower jaw recording bow and an upper jaw recording bow which can be brought into an active and predetermined relation with respect to the articulator and which disposes of at least three recording plates with corresponding recording pins as well as positioning spoons for the combination of a lower jaw dentition model. With this device, opening movements of articulation may be recorded three-dimensionally so that three clear crossing points are created for the occlusion.
