Porous titanium substrates coated with a bilayer of bioactive glasses
(Elsevier, 2020-09)
Porous titanium substrates coated by dripping-sedimentation technique with a novel bilayer of (45S5 / 1393) bioactive glasses are proposed to overcome some limitations of the use of titanium for implants, such as the stress ...

Synthesis and deposition of silver nanoparticles on porous titanium substrates for biomedical applications
(Elsevier, 2021-01)
Ti implants are highly biocompatible and allow orderly bone growth but, unfortunately, in the first five years after implantation, 5–10% of them fail due to poor osseointegration and to the presence of bacterial infections ...

Synergistic Effect of rhBMP‐2 Protein and Nanotextured Titanium Alloy Surface to Improve Osteogenic Implant Properties
(MDPI, 2021-03)
One of the major limitations during titanium (Ti) implant osseointegration is the poor cellular interactions at the biointerface. In the present study, the combined effect of recombinant human Bone Morphogenetic Protein-2 ...

Desarrollo de titanio con porosidad gradiente radial y longitudinal para aplicaciones biomédicas
(2017-03-10)
La diferencia de rigidez entre el tejido óseo y los implantes de Titanio (Ti) implica un apantallamiento de tensiones que promueve la reabsorción ósea y un incremento de la probabilidad de fractura. Los objetivos principales ...

Bioactive Bilayer Glass Coating on Porous Titanium Substrates with Enhanced Biofunctional and Tribomechanical Behavior
(MDPI, 2022-02)
The use of porous titanium samples fabricated by space-holder powder metallurgy with bioactive coatings has already been reported to prevent resorption of the bone surrounding the implant and improve osseointegration, ...

Design, processing and characterization of titanium with radial graded porosity for bone implants porosity for bone implants
(Elsevier, 2016-07)
Titanium cylinders with radial graded porosity, which are potentially suitable for biomedical applications (replacement of cortical and trabecular bones involved in different joint and dental restorations), have been ...

Bacterial behavior on coated porous titanium substrates for biomedical applications
(Elsevier, 2019)
In this work, bacterial behavior on dense and porous titanium substrates is discussed. Porous titanium was fabricated by a space holder technique (using 50 vol%, NH4HCO3 with particle sizes between 250 and 355 μm). These ...

Directed Irradiation Synthesis as an Advanced Plasma Technology for Surface Modification to Activate Porous and “as-received” Titanium Surfaces
(MDPI, 2019)
For the design of smart titanium implants, it is essential to balance the surface properties without any detrimental effect on the bulk properties of the material. Therefore, in this study, an irradiation-driven surface ...

Sol-gel deposition of hydroxyapatite coatings on porous titanium for biomedical applications
(Elsevier, 2018)
The stress shielding and the poor osseointegration in titanium implants are still problems to be resolved. In this context, this work proposes a balanced solution. Titanium samples were fabricated, with a porosity of ...
