The stress distribution underneath denture base and the resorption of alveolar bone are closely related to each other. In our recent studies with three-dimensional and two-dimensional finite element methods (2-D and 3-D FEM), the stress distribution was evaluated for removable dentures and their supporting structures. The purpose of this study was to validate the 3-D FEM and 2-D FEM models with experimental model as well as to compare the 3-D analysis with 2-D analysis. According to our results, the stress distribution of 3-D FEM was similar to the results of the experimental model. 2-D FEM tended to show exaggerated results compared with those 3-D FEM.
This study was designed to attest the hypothesis that trabecular patterns of mandible are closely related to the stress distribution or the load transmission pattern. Two-dimensional
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
