Use of Impedance Spectroscopy for the Characterization of In-Vitro Osteoblast Cell Response in Porous Titanium Bone Implants
(MDPI, 2020-08)
The use of titanium implants with adequate porosity (content, size and morphology) could solve the stress shielding limitations that occur in conventional titanium implants. Experiments to assess the cellular response ...

Tribo-mechanical and cellular behavior of superficially modified porous titanium samples using femtosecond laser
(Elsevier, 2021-09)
In this work, the surface of porous titanium samples obtained by the space-holder technique was treated with a femtosecond laser to improve their osseointegration. Instrumented micro-indentation and scratch test were ...

Electrical Impedance of Surface Modified Porous Titanium Implants with Femtosecond Laser
(MDPI, 2022-01)
The chemical composition and surface topography of titanium implants are essential to improve implant osseointegration. The present work studies a non-invasive alternative of electrical impedance spectroscopy for the ...

In Vitro Bone Cell Behavior on Porous Titanium Samples: Influence of Porosity by Loose Sintering and Space Holder Techniques
(MDPI, 2020-05-25)
A great variety of powder metallurgy techniques can produce biomimetic porous titanium structures with similar mechanical properties to host bone tissue. In this work, loose sintering and space holder techniques, two ...

Surface Modification of Porous Titanium Discs Using Femtosecond Laser Structuring
(MDPI, 2020-06)
The failure of titanium implants is associated with two main problems that include the bone resorption and fracture of the surrounding bone tissue (stiffness incompatibility) and implant loosening (poor osseointegration). ...
