Comparison of zirconia degradation in dental implants and femoral balls: an X-ray diffraction and nanoindentation study
Gil Mur, Francisco Javier; Delgado‑García‑Menocal, José Angel; Velasco-Ortega, Eugenio; Bosch Canals, Begoña Maria; Delgado, Luis M.; Pérez Antoñanzas, Roman; Fernandez-Fairen, Mariano (International Journal of Implant Dentistry, 2021)Background: New tetragonal zirconia polycrystal dental implants stabilized with yttria (Y-TZP) have appeared in the implantology market in the form of single piece or two-piece zircona implant system. ... -
Fracture and fatigue of titanium narrow dental implants: new trends in order to improve the mechanical response
Velasco-Ortega, Eugenio; Flichy-Fernández, Antonio; Punset fuste, Miquel; Jiménez-Guerra, Alvaro; Manero, José María; Gil Mur, Francisco Javier (Materials, 2019-11-12)Sixty-four fractured commercially pure titanium (cp-Ti) narrow dental implants (NDIs) with similar macrogeometry and connection designs were studied after different implantation times in humans in order ... -
Influence of connection type and platform diameter on titanium dental implants fatigue: non-axial loading cyclic test analysis
Nicolas-Silvente, Ana Isabel; Velasco-Ortega, Eugenio; Ortiz-Garcia, Iván; Jiménez Guerra, Álvaro; Monsalve-Guil, Loreto; Ayuso-Montero, Raul; Gil Mur, Francisco Javier; Lopez-Lopez, Jose (International Journal of Environmental Research and Public Health, 2020)Two-pieces dental implants must provide stability of the implant-abutment-interface. The connection type and platform diameter could influence the biomechanical resistance and stress distribution. This ... -
Influence of the titanium implant surface treatment on the surface roughness and chemical composition
Nicolas-Silvente, Ana Isabel; Velasco-Ortega, Eugenio; Ortiz-Garcia, Iván; Monsalve-Guil, Loreto; Gil Mur, Francisco Javier; Jiménez Guerra, Álvaro (Materials, 2020)The implant surface features affect the osseointegration process. Different surface treatment methods have been applied to improve the surface topography and properties. Trace of different elements may ... -
Optimization of titanium dental mesh surfaces for biological sealing and prevention of bacterial colonization
Cruz, Nuno; tondela, joão paulo; Martins, Maria Inês; Velasco-Ortega, Eugenio; Gil, FJ (Materials, 2022)Titanium dental meshes have a wide application in order to ensure the retention of calcium phosphate-based biomaterials to regenerate bone tissue. These meshes are temporary and must grow a soft tissue ... -
Osteoblastic cell behavior and gene expression related to bone metabolism on different titanium surfaces
Velasco-Ortega, Eugenio; Fos-Parra, Isabel; Cabanillas-Balsera, Daniel; Gil, FJ; Ortiz-García, Iván; Giner, Mercè; Bocio-Núñez, Jesús; Montoya-García, María-José; Jiménez-Guerra, Álvaro (International Journal of Molecular Sciences, 2023)The surface topography of titanium dental implants has a great influence on osseointegration. In this work, we try to determine the osteoblastic behavior and gene expression of cells with different ... -
Relevant aspects of titanium topography for osteoblastic adhesion and inhibition of bacterial colonization
Rodriguez-González, Raquel; Monsalve-Guil, Loreto; Jimenez-Guerra, Alvaro; Velasco-Ortega, Eugenio; Moreno Muñoz, Jesús; Nuñez-Marquez, Enrique; Perez, Roman; Gil, FJ; Ortiz-Garcia, Ivan (Materials, 2023)The influence of the surface topography of dental implants has been studied to optimize titanium surfaces in order to improve osseointegration. Different techniques can be used to obtain rough titanium, ... -
Titanium surface characteristics induce the specific reprogramming of toll-like receptor signaling in macrophages
González-Sánchez, Zaira; Areal-Quecuty, Victoria; Jimenez-Guerra, Alvaro; Cabanillas-Balsera, Daniel; Gil, FJ; Velasco-Ortega, Eugenio; Pozo Perez, David (International Journal of Molecular Sciences, 2022)Most of the research on titanium-based dental implants (Ti-discs) is focused on how they are able to stimulate the formation of new tissue and/or cytotoxic studies, with very scarce data on their effects ...
