Assessment of impact of relief at the median palatal plate on denture-supporting ability

Background: The present study was conducted for assessing the impact of relief at the Median Palatal Plate on Denture-supporting Ability. Materials & methods: The present study was conducted for assessing the impact of relief at the Median Palatal Plate on Denture-supporting Ability. In 20 dentulous subjects, pseudopalatal plates were affixed to the palatal mucosa. The relief at the median palatal plate was categorized as: No-relief, 0.25 mm relief, and 0.50 mm relief. All the results were recorded and analysed by SPSS software. Results: During the pain onset, both clenching force and subsidence of the palatal mucosa in the 0.25 and 0.50-mm relief conditions were greater than those under the no-relief condition. The results were found to be statistically significant. However, while comparing in between the 0.25 and 0.50 mm relief conditions, there was no significant difference. Conclusion: The relief area of maxillary full dentures suitable for individual patients was determined in an objective and convenient manner with improved accuracy using this technique
