- Chemical and Microscopy Characterization of Trans-Endodontic Implants Alexis Larios-Cervantes Luis Aguilera-Galaviz Héctor Flores Reyes Víctor Hugo Baltazar Hernández Crescencio Rodríguez César Gaitán-Fonseca Medicina Trans Energy dispersive X Zirconium oxide Vickers hardness Trans-endodontic implants are an artificial extension through root apex anchored in periradicular bone tissue. The aim is to improve the crown-root ratio and to provide stability to dental organ present. Zirconium oxide (ZrO2) 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 ZrO2 trans-endodontic implant. Materials and Methods: A blocks of ZrO2 were manufactured for produce trans-endodontic implants and divided in two groups: monoclinic and tetragonal phase. They were evaluated using Scanning Electroning Microscope (SEM), EnergyDispersive 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. 2018 artículo científico 1659-1046 https://www.redalyc.org/articulo.oa?id=499557633008 https://www.redalyc.org/journal/4995/499557633008/ https://www.redalyc.org/journal/4995/499557633008/html/ https://www.redalyc.org/journal/4995/499557633008/499557633008.epub https://www.redalyc.org/journal/4995/499557633008/movil 10.15517/ijds.v0i0.30282 en http://www.redalyc.org/revista.oa?id=4995 Odovtos - International Journal of Dental Sciences application/pdf Universidad de Costa Rica Odovtos - International Journal of Dental Sciences (Costa Rica) Num.2 Vol.20
