This author planned to clarify. the influence of differences in palatal depth and the amount of load on the bearing stress on the basal seat under this type of denture. He consequently investigated the effectiveness of a stress-sensor usable on curved areas, and using simulation models of upper maxillas with three different palatal depths, investigated the influence that different amounts of load on an artificial molar might have on bearing stress on the basal seat under the denture in terms of deformation and displacement (direction and quantity). The findings can be summarized as follows,Deformation and vertical and lateral displacement of dentures were influenced by differencesin palatal depth and the amount of load. This discovery was useful for measuring the bearingstress on the basal seat under the denture. The above results lead us to conclude that the supporting area of the basal seat under the denture for the upper maxilla was mainly the alveolar ridge, and that the palatal side of the ridge could also become a supporting area when the palate grew smaller. this indicates that palataldepth is an important clinical clue for surmising the supporting area of the basal seat under the denture whose bearing stress must be reduced.
