The aim is to improve the crown-root ratio and to provide stability to dental organ present. Zirconium oxide (ZrO</span><span>2</span><span>) is a material of great technological importance, having good natural color, high strength, high toughness, high chemical stability, does not suffer any corrosion, chemical and microbial resistance and excellent esthetic properties.  Objective: The aim of this study was to evaluate chemical and microscopy of surface conditions of ZrO</span><span>2</span><span> trans-endodontic implant. Materials and Methods: A blocks of ZrO</span><span>2</span><span> were manufactured for produce trans-endodontic implants and divided in two groups: monoclinic and tetragonal phase. They were evaluated using Scanning Electroning Microscope (SEM), Energy-Dispersive X-ray Spectroscopy (EDS), and Atomic Force Microscope (AFM) and Vickers Micro hardness. Results: The Monoclinic phase through AFM analysis showed roughness Ra = 0.320μm, whereas in the Tetragonal phase was 0.126μm, SEM/EDX indicated that the phases are not properly uniform and the addition of the Yttrium to favor the stabilization of the Tetragonal phase. The Vickers hardness analysis showed a value of 1500HV.  Conclusion: The characterization of the surface of trans-endodontic zirconium oxide implants provides a guideline to know the surface characteristics of the material, since a greater roughness on the surface of the implant will favor the Osseo-integration capacity.</span></p><div><span><br /></span></div>}, number={2}, journal={Odovtos - International Journal of Dental Sciences}, author={Larios-Cervantes DDS, Alexis and Aguilera-Galaviz DDS, MSc, PhD, Luis and Flores Reyes DDS, MSc, PhD, Héctor and Baltazar Hernández DDS, MSc, PhD, Víctor Hugo and Rodríguez DDS, Crescencio and Gaitán-Fonseca DDS, MSc, PhD, César}, year={2018}, month={May}, pages={81–89} }
