Abstract

In order to clarify the functional differences between the 2 typical path patterns (I and III) in normal subjects, the masticatory efficiency and the function of the mandibular movement during gumi-jelly chewing were compared quantitatively between pattern I (20 subjects: smooth opening toward working side, and convex closing) and pattern III (20 subjects: opening toward working side after initially toward nonworking side, and convex closing). The results were as follows:<BR>1. For the amount of opening, no significant difference was found between the two patterns, though that of pattern I group was slightly larger.<BR>2. Pattern III group had a larger masticatory width than pattern I group, and a significant difference was found between the two groups.<BR>3. Pattern III group had a longer cycle time than pattern I group, and a significant difference was found between the two groups.<BR>4. Pattern I had a larger amount of glucose secretion than pattern III group, and a significant difference was found between the two groups.<BR>5. From the above, it was concluded that a functional difference was observed between the two patterns and that pattern I had a superior mandibular function and masticatory efficiency than pattern III.
