Objective: To analyse through the evaluation of the articles found in this literature review, the usefulness of Finite Element Method in determining fracture mechanisms les Ni-Ti and correlated with experimental results. Materials and methods: A search of the literature aiming experimental and theoretical studies in databases and journals was performed. Results: The comparison of the experimental and theoretical results Mtwo® found that the best system is the cyclical fracture resistance occurs in correlation with low accumulation of Von Mises stress, the ProTaper® system has low tensile strength cyclic correlated with a large accumulation of Von Mises stress in extreme conditions, the QUANTEC® system was more exible but with a large accumulation of Von Mises stress system. Conclusions: We found that the nite element method has agreement with experimental methods; in rotary systems the best for handling curved canals is the Mtwo® system, ProTaper® system is the best torsional resistance presents; concluded that the cross-sectional design of the le is directly related to the mechanical performance of it.
