Device for the representation and correction of condylar motions

Improved device for the representation of condylar movements of a patient and their correct simulation, including models of sets of teeth to determine the required corrections to the biting surfaces in order to obtain an ideal occlusion, which mainly consists of an articulator (1) with the lower part of the articulator (1) that can be brought in a predetermined three-dimensional relation to the upper part of the articulator (2), with two blocks (11, 12) with guide elements on the lower part of the articulator (1) for the support of the condyle balls (14) of the upper part of the articulator (2) and means for the defined and reproducible mounting of the lower jaw dentition model and the upper jaw dentition model (6, 7) as well as a pantograph part (3) removably connected to said articulator and consisting of a lower jaw recording bow (4) and an upper jaw recording bow (5) that can be brought in an active and predetermined relation to the articulator (1) and disposes of at least three recording plates (18, 19, 20) with the corresponding recording pins (25, 26, 27) as well as positioning spoons (17) for the combination of a lower jaw dentition model (8) with the lower jaw recording bow (4) and an upper jaw dentition model (9) with the upper jaw recording bow (5), that characterize the whole device with three recording plates in co-operation with the Mc Grane support pin, arranged on an especially formed guide plane in a certain distance and position, that the opening movements of the articulation are recorded fully three-dimensionally, so that three clear crossing points are created for the occlusion and that the lower part of the articulator (1) disposes of a single middle support (10), which carries the two blocks (11, 12) of the guide elements on a common axis, whereas the upper part can always be folded back freely and stably, parallel to the lower part.
