In this study, mandibular movement was measured in six degrees of freedom with a new analyzing system for stomatognathic functions. Incisor and bilateral condylar point movements were investigated in 20 normal subjects. The results were as follows 1. At the incisor point, 11 subjects showed typical movement pattern, and 9 subjects showed other movement patterns. 2. At bilateral condylar points, 14 subjects showed typical movement pattern, and 6 subjects showed other movement patterns. 3. Only 7 subjects showed typical movement pattern at both incisor and bilateral condylar points. From the results, the relationship between incisor and bilateral condylar point movements are not always paired.
