Influence of the Elements of Mandibular Movement on Tooth Path. Part 6. Condylar Inclination of Nonworking-side Condyle Path.

The object of this study was analyze mathematically the effect of condylar inclination of the nonworking-side condyle path on the tooth path.Conclusions of the calculation are;1. Error of the tooth path was proportinate to and smaller than that of condylar inclination of the nonworking-side condyle path.2. The relation of errors between condylar inclination of the nonworking-side condyle path and tooth path was hardly affected, even when the direction of condyle movement and the inclination of the sagittal incisal path was altered.3. Amount of error of the nonworking-side molar path was generally equivalent to a half amount of the condylar inclination of the nonworking-side condyle path, while that of the workingside molar path was a sixth thereof.
