he aim of this study was to analyse the stress distribution in maxillary canines restored with different post systems and definitive crowns. The models of restored teeth with glass fiber, quartz fiber, titanium posts and crowns were developed with the Finite Element Method (FEM) in order to analyse their stress distribution when subjected to external compressive loads. Von Mises stress distribution values, which are considered potential fracture indicator, showed thatnatural tooth and glass fiber post-restored tooth, under a load of 550 N, presented similar stress values. The behaviour of aglass fiber post-restored tooth is similar to that of a natural tooth, since it produces an appropriate stress distribution, and inthis investigation, they have the best biomechanical performance.
