The purpose of this study was to investigate the correlation between the maximal opening and skeleton in dental students of our school without functional disorders of the masticatory system. In 99 males and 86 females, the stature and maximal opening were recorded. Out of these subjects, 29 males and 31 females agreed to have lateral cephalogram taken in both the closed and maximal opening positions. The results were as follows. 1. The correlation between the maximal opening and stature, and mandibular length or mandibular angle were significant. 2. The correlation between the maximal opening and the movement of the condyle was significant. 3. The correlation between the movement of the condyle and the distance of the Sera-Nasion was significant. 4. It became evident from these studies that the maximal opening was in close relation to the size of the skeleton.
