N2 - The aim of this research was to perform a numerical stress analysis in a zirconia dental implant virtually inserted in a maxilla bone. A zirconia one-piece dental implant was scanned with a CAD-CAM dental system and a 3D geometry.stl file was exported and processed into a numerical model to perform a simulation with finite elements.A qualitative analysis was performed using unitary load in a vertical and oblique direction. Results of the stress analysis with FEM showed that the highest stresses are located in the abutment of the implant when a vertical load is applied and when an oblique load is used there is also a stress concentration on the implant but this time in the surface opposed to the load. Therefore, it seems that there is not an increased risk of implant failure, when compared to traditional titanium implants.
