Analysis of Forces Transmitted by Upper Complete Dentures to the Supporting Tissue to Contribute to Better Denture Design

In this communication, a denture cross-sectional rib through the molars is analyzed for the applied masticatory force transmission to the supporting tissue. The denture arch is analyzed in order to determine how the arch geometry and dimensions influence the manner in which the arch transfers the support forces and moments (which represent the masticatory loads) to the supporting tissue. The analysis is carried out for a circular denture arch conforming to a circular palatal section. Factors representing ratios of masticatory loads (in terms of forces acting at the arch supports) to the tissue-bearing pressure are presented as nomograms, for various denture arch dimensions.
