There have been not many experimental studies about the influence of incisal path on condylar path, though it is important to know it in clinic. By changing the sagittal inclination of incisal path, the condylar path was influenced both in distance and in inclination.
When the sagittal inclination of incisal path was smaller than that of condylar path, the distance of the tracing of the kinematic-axis point was longer than that of incisal path. The smaller the inclination angle of the incisal-condylar points line in the sagittal view was, the longer the distance of condylar path was.
The inclination angle of the tracing of the arbitrary condylar points depended on its locational relationship with the specific line that intersects at nearly right angles to the condylar path through the kinematic-axis point. That is, the arbitrary condylar points on the specific line had reproducible inclination angle of condylar tracing equally as that of the kinematic-axis point. When the inclination angle of incisal path was smaller than that of condylar tracing, the points located in front of the specific line had larger inclination angle, and the points located behind the specific line had smaller inclination angle.
