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 ...

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, ...

Porous Titanium Cylinders Obtained by the Freeze-Casting Technique: Influence of Process Parameters on Porosity and Mechanical Behavior
(MDPI, 2020)
The discrepancy between the stiffness of commercially pure titanium and cortical bone tissue compromises its success as a biomaterial. The use of porous titanium has been widely studied, however, it is still challengi ...

Development and implementation of a sequential compaction device to obtain radial graded porosity cylinders
(Elsevier, 2020)
In this work, a sequential compaction device has been successfully developed and implemented to produce commercially pure titanium cylinders, in which the porosity increases from the core to the surface or vice versa. The ...
