This methodology requires elevated computer-aided design skills to reproduce the geometry of the endodontic file, and also mathematical knowledge to perform the finite element analysis. In this study, an automated procedure is proposed for the computerized generation and finite element analysis of endodontic rotary files under bending and torsional conditions. Methods: An endodontic rotary file with a 25mm total length, 0.25mm at the tip, 1.20mm at 16mm from the tip, 2mm pitch and squared cross section was generated using the proposed procedure and submitted for analysis under bending and torsional conditions by clamping the last 3mm of the endodontic rotary file and applying a transverse load of 0.1N and a torsional moment of 0.3N.cm. Results: The results of the finite element analyses showed a maximum von Mises stress of 398MPa resulting from the bending analysis and a maximum von Mises stress of 843MPa resulting from the torsional analysis, both of which are next to the encastre point. Conclusions: The automated procedure allows an accurate description of the geometry of the endodontic file to be obtained based on its design parameters as well as a finite element model of the endodontic file from the previously generated geometry. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.838 2021 ENGINEERING, MULTIDISCIPLINARY 39 / 92 = 0.424 2021 Q2 T2 PHYSICS, APPLIED 76 / 161 = 0.472 2021 Q2 T2 MATERIALS SCIENCE, MULTIDISCIPLINARY 218 / 345 = 0.632 2021 Q3 T2 CHEMISTRY, MULTIDISCIPLINARY 100 / 180 = 0.556 2021 Q3 T2 0.507 2021 Engineering (miscellaneous) 2021 Q2 Computer Science Applications 2021 Q2 Process Chemistry and Technology 2021 Q2 Materials Science (miscellaneous) 2021 Q2 Fluid Flow and Transfer Processes 2021 Q2 3.7 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Zubizarreta-Macho, A Sanchez-Marin, F Alonso Ezpeleta, O Universidad de Zaragoza (orcid)0000-0003-3868-6784 Albaladejo Martinez, A Galparsoro Catalan, A 1013 275 Universidad de Zaragoza Dpto.
