Abstract: The present invention relates to an articulator for the purpose of checking the alignment of dentures, by coupling together models of the upper and a lower jaws, in order to provide a simple movement of the upper and lower jaws, minimize occlusal errors, and accurately mount the upper and lower jaws onto the occlusion surface. Conventional articulators imitate the form of upper and lower jaw movements, wherein a reference axis is established and folded in accordance with a condyle, however, the process completely eliminates muscle movement, and inevitably leads to occlusal errors during upper and lower jaw movement. Consequently, the problem with conventional articulators is the need for post-processing, regardless of the extent of reduction of the occlusal errors through the use of diverse assisting means. In addition, while accurate occlusion cannot be achieved, conventional articulators have a structure that is too complicated and difficult to operate.
