| Outline of Final Research Achievements |
We developed a new maxillary palatal plate-form device that can simultaneously analyze the relationship between clenching force and subsidence of the palatal mucosa at pain onset during jaw clenching for denture-supporting ability. In 15 dentulous cases the pseudo-palatal plate was affixed to the palatal mucosa; anterior splints were affixed as a maxillary reference for measuring subsidence of plate, while clenching force was transmitted to the pseudo-palatal plate via a pressurizing splint was affixed to the mandible. The reliefs of the pseudo-palatal plates were "no-relief","0.23-mm relief", and "0.46-mm relief" at the median palatal plate. Subjects clenched their jaws until pain onset; the clenching force and subsidence of the palatal mucosaat pain onset were simultaneously measured. Both the clenching force and subsidence of the palatal mucosa at pain onset increased significantly in the 0.23-mm and 0.46-mm relief compared to the no-relief categories (p < 0.05).
