Two three-dimensional models were created and assembled. All models were subjected to a natural masticatory force of 118 N in the angle of 75° to the occlusal plane. All degrees of freedom in the inferior border of the cortical bone were restrained, and the mesial and distal borders of the end of the bone section were constrained. Fatigue material data and loads were assumed as random variables. Maximum principal stresses on bone were evaluated. Then, the probability of failure was obtained by the probabilistic approach. The maximum principal stress distribution predicted in the cortical and trabecular bone is 32 MPa for external connection and 39 MPa for internal connection. A mean life of 103 and 210 million cycles were obtained for external and internal connection, respectively. Probability cumulative function was also evaluated for both connection types. This stochastic model employs a cumulative damage model and probabilistic finite element method. This methodology allows the possibility of measured uncertainties and has a good precision on the results. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 1.769 2017 ROBOTICS 16 / 26 = 0.615 2017 Q3 T2 ENGINEERING, BIOMEDICAL 49 / 78 = 0.628 2017 Q3 T2 0.288 2017 Bioengineering 2017 Q3 Medicine (miscellaneous) 2017 Q3 Biotechnology 2017 Q3 Biomedical Engineering 2017 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0002-9417-2705 Bea, José Antonio Universidad de Zaragoza Rojo, Rosa Gehrke, Sergio A.
