The objective of this study is to explain mathematically the effect of curvature of horizontal balancinz condylar path and direction of working condylar path on tooth path. Conclusions from the calculation were ; 1. The direction of working condylar path, especially on posterior-external-superior laterotrusion, affected remarkably the relation of curvature of horizontal balancing condylar path and tooth path. 2. As the direction of worlcing condylar path was made greater toward posterior-external-superior, curvature of tooth path increased similar to that of horizontal balancing condylar path. From the facts described above, throuzh another attemtct of condylar path on the humanlateral excurtion, the following results were obtained ; 3. On the human lateral excursion, it was very little case that put larger curvature of horizontal balancing condylar path and working condylar path in posterior-external-superior direction together. 4. For this reason, it is clinically almost unnecessary to reproduce curvature of horizontal balancing condylar path on articulator.
