Occlusal force is one method for preventing elevation of the cast crown at cementation. For the purpose of examining changes in occlusal force with time, this study was designed to measure continuous occlusal force and to compare the occlusal force of male and female, and of the left and right upper first molars. In addition, the relation of the habitual side of occlusion with momentary individual occlusal force, and with magnitude of continuous occlusal force was examined. The results were as follows ; 1. When continuous occlusal force was compared between male and female, a rapid decrease occurred immediately after mesurement in the case of female. In addition, continuous occlusal force decreased to less than 15kg after about 50 seconds in the case of male, and after about 20 seconds in the case of female. 2. When continuous occlusal force was compared between the left and right upper first molars, the left side showed a slightly higher tendency than the right side. But no significant difference was found. 3. On the relation of the habitual side of occlusion with momentary individual occlusal force and with magnitude of continuous occlusal force, about 59% agreement was found in the former and about 45% agreement in the latter.
