Abstract

A three-dimensional finite element model was developed using the ABAQUS code to characterize dental systems in their different functional conditions, geometry and loading modes.The outputs of the model were used to evaluate quantitatively the magnitude and distribution of the stress-strain-displacement relations in sound (drilled and enamel crown) and restored with prefabricated intrarradicular posts (conical and cylindrical) premolar teeth specimens.Under the same loading and boundary conditions, differences in stresses, displacements and elastic strains were observed for drilled, enamel crown, conical and cylindrical post teeth specimens. It was found that the cylindrical glass fiber post geometry minimizes much better the stress, displacement and elastic strain magnitude in premolar teeth.The results indicate that the finite element methodology is adequate and convenient for stress, displacement and strain assessment in orthodontics.
