ABSTRACT

Objective To construct three-dimensional finite element model (3-D FEM) of maxillary complete denture and its supporting tissues with different shapes of palatal vault and different teeth cusp inclination. Methods Based on the data of 3-D measurement, using MATLAB 6.1 and ALGOR FEAS software, 3-D FEM was constructed by computer. Results 3-D FEM of maxillary complete denture was constructed with three different palatal vault and three different teeth cusp inclination (10?, 20?, 30?) and supporting tissues. Conclusion 3-D FEM can be used for the analysis of the effect of different shapes of palatal vault and different teeth cusp inclination on the stress distribution of maxillary complete denture under different loading conditions.
