Designing, processing and characterisation of titanium cylinders with graded porosity: An alternative to stress-shielding solutions
(Elsevier, 2014)
Bone resorption events and consequent failure of titanium implants are frequently related to stress-shielding problems, due to stiffness mismatch with respect to bone. This is a mechanical incompatibility problem, which ...

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 ...

Balancing porosity and mechanical properties of titanium samples to favor cellular growth against bacteria
(MDPI, 2019)
Two main problems limit the success of titanium implants: bacterial infection, which restricts their osseointegration capacity; and the stiffness mismatch between the implant and the host cortical bone, which promotes bone ...
