Abstract: A dental articulator, having a spatially oriented mounting table permanently bonded to the one frame, allows for the positioning of mounting plates on the upper and lower frames of an articulator. The first mounting plate is oriented exactly the same on the same frame of each articulator. The mounting plate table, capable of orienting the second mounting plate within a range of positions, is fixed both vertically and horizontally by means of a special mounting block. Therefore, the mounting plate table being fixed, mounted dental casts on the mounting plates may be transferred from one articulator to the other without introduction of vertical or horizontal errors. As a result the relationship of the upper mounting plate to the hinge axis will be the same for each articulator. Additionally, the vertical and horizontal relationship of the lower mounting plate to the upper mounting plate will be the same.
