Methods: Uncertainties on material properties due to the existence of defects that cause material elastic constant are not the same in the whole dental implant the dimensions of the structural element and load history have a decisive influence on the fatigue process and therefore on the life of a dental implant. In order to measure these uncertainties, we used a method based on Markoff chains, Bogdanoff and Kozin cumulative damage model, and probabilistic finite elements method. Results: The results have been obtained by conventional and probabilistic methods. Mathematical models obtained the same result regarding fatigue life; however, the probabilistic model obtained a greater mean life but with more information because of the cumulative probability function. Conclusions: The present paper introduces an improved procedure to study fatigue behaviour in order to know statistics of the fatigue life (mean and variance) and its probability of failure (fatigue life versus probability of failure). info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.134 2015 MEDICINE, RESEARCH & EXPERIMENTAL 72 / 124 = 0.581 2015 Q3 T2 BIOTECHNOLOGY & APPLIED MICROBIOLOGY 81 / 161 = 0.503 2015 Q3 T2 0.854 2015 Biochemistry, Genetics and Molecular Biology (miscellaneous) 2015 Q2 Medicine (miscellaneous) 2015 Q2 Immunology and Microbiology (miscellaneous) 2015 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Prados-Frutos, Juan Carlos Manchón, Ángel Rojo, Rosa Felice, Prieto (orcid)0000-0002-9417-2705 Bea, José Antonio Universidad de Zaragoza 5004 605 Universidad de Zaragoza Dpto.
