Resumen
[EN] The objective of the present study is to evaluate how the elastic properties of the fabrication material of dental implants influence
peri-implant bone load transfer in terms of the magnitude and distribution of stress and deformation. A three-dimensional (3D)
finite element analysis was performed; themodel used was a section ofmandibular bonewith 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.
