下顎運動要素の歯牙路への影響 その７ 平衡側側方か路角

Abstract

The object of this study was to analyze mathematically the effect of lateral condylar path of nonworking side on tooth paths.The conclusions of calculation were1. The error that gives the lateral condylar path of the nonworking side is directly proportional to the error that appears in tooth paths. The error of tooth path was about 90% of the error's value which produces the lateral condylar path of the nonworking side.2. The relation between the lateral condylar path of the nonworking side and tooth paths is not influenced by the direction of nonworking condylar movement or the angle of the sagittal incisal path. However, it is influenced by the direction of working condylar movement.3. Angle of the lateral condylar path has more influences on the angle of tooth paths than that of the sagittal condylar path as for the condylar path of the nonworking side.
