A three-dimensional (3D) finite element analysis was performed; the model used was a section of mandibular bone with a single implant containing a cemented ceramic-metal crown on a titanium abutment. The following three alloys were compared: rigid (Y-TZP), conventional (Ti-6Al-4V), and hyperelastic (Ti-Nb-Zr). A 150-N static load was tested on the central fossa at 6° relative to the axial axis of the implant. The results showed no differences in the distribution of stress and deformation of the bone for any of the three types of alloys studied, mainly being concentrated at the peri-implant cortical layer. However, there were differences found in the magnitude of the stress transferred to the supporting bone, with the most rigid alloy (Y-TZP) transferring the least stress and deformation to cortical bone. We conclude that there is an effect of the fabrication material of dental implants on the magnitude of the stress and deformation transferred to peri-implant bone. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.476 2016 BIOTECHNOLOGY & APPLIED MICROBIOLOGY 66 / 160 = 0.412 2016 Q2 T2 MEDICINE, RESEARCH & EXPERIMENTAL 65 / 128 = 0.508 2016 Q3 T2 0.885 2016 Medicine (miscellaneous) 2016 Q1 Biochemistry, Genetics and Molecular Biology (miscellaneous) 2016 Q2 Immunology and Microbiology (miscellaneous) 2016 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Brizuela Velasco, Aritza Chávarri Prado, David Jiménez Garrudo, Antonio Sánchez Lasheras, Fernando Solaberrieta Méndez, Eneko Diéguez Pereira, Markel Fernández González, Felipe J.
