Abstract
The Finite Element Method allows to evaluate situations involving complex geometries and loads that are difficult to find through experiments. Increasingly, it has been used in the analysis of biomechanical systems, such as instruments and dental prostheses. One of these complex situations is the endodontic treatment (canal treatment), where an instrument (file) is used to perform cleaning and shaping of the root canal. The anatomy (geometry) of the canal varies for each person and group of teeth. The instruments used must withstand different types of stresses such as shear, torsion and bending, and have the flexibility to follow the anatomy of the canal without causing deviations. Due to the difficulty of analyzing the tensions developed in the instrument during endodontic treatment, the objective of the present work was to develop and validate, through mechanical tests, a three-dimensional model of the Endodontic Instrument. Through this model it was possible to analyze the tensions developed in the instrument of different materials and for use in different anatomies.
