説明

The purpose of this study was to ascertain the relationship between the development of the stomatognathic system and the changing of the mandibular movement.<BR>The subjects consisted of 48 children without functional disorders of the stomatognathic system and were divided into groups from IIA to IIIC according to Hellman's dental stages.<BR>The Saphon Visi-Trainer was used as the analytic method. The mandibular border movement at the mandibular incisor was recorded using the Saphon Visi-Trainer Model 3, and was examined as to how it changed according to the progress of Hellman's dental stage.<BR>As a result, the following findings were obtained:<BR>1. According to the progress of Hellman's dental stage, the mandibular border movement was enlarged towards the anterior, exterior, inferior and posterior.<BR>2. Changing of the right and left maximal lateral occlusal positions of the mandible corresponding to the progress of Hellman's dental stage tended toward symmetry.<BR>3. Corresponding to the Hellman's dental stage, the paths of the protrusive and lateral gliding movements moved downward and showed downward convex curved lines.
