ABSTRACT: The main objective of this study was to
compare the results obtained with both virtual and experimental research
methods, when the biomechanical behavior of teeth restored with esthetic posts
was investigated. The finite element method was used to develop models of
healthy maxillary canines and maxillary canines restored with definitive crowns
and glass-fiber posts, quartzfiber posts, and titanium posts. Stress
distribution was observed when external loads were applied. Load was applied in-vitro to analyse the fracture
resistance of 48 maxillary canines restored in the same way as it was
considered in the virtual method. The analysis of results using the finite element method led to the
conclusion that restored teeth, in which the elastic modulus of the post was
similar to that of the dentine and the material of the core had the best
biomechanical performance. The experimental study validated the virtual
analysis.
