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 ...

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 ...

Designing bioactive porous titanium interfaces to balance mechanical properties and in vitro cells behavior towards increased osseointegration
(Elsevier, 2019)
Titanium implant failures are mainly related to stress shielding phenomenon and the poor cell interaction with host bone tissue. The development of bioactive and biomimetic Ti scaffolds for bone regeneration remains a ...
