The concept of Tsubone's theory of occlusion is that the mandible moves basically in a conical guide path. In other words, the condylar guidance which is the posterior guidance factor for the mandibular movement is not a simple plane orbit, but is a curvature, which can be substituted with a cone. The dental arch of the anterior teeth which is the anterior guidance factor for the mandible also is about circular, which in three dimensions can be substituted with a cone. With these things taken into consideration, the condylar guide plane on Tsubone's articulator is composed of three dimensional fan-shaped orbit and the incisal guidance path conical. When the condylar guide plane guidance and the incisal guidance path are conical, the occlusal surface form situated in midway should naturally be conical in the basic form. With these in mind, artificial non-anatomical teeth (0 degree) were developed with conical pivot provided for the maxilla and conical cavity to mate for the mandible. Thus an articulator and artificial teeth based on Tsubone's theory of occlusion were completed.
