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 ...
