Titanium for biomedical application with radial graded porosity: Development of a novel compaction device

摘要

Bone tissue damages due to traumas and degenerative diseases are potentially treatable by tissue engineering practice with metallic scaffolds. Surface and bulk properties of titanium are critical for implants success because they can be suitably tailored to mimic bone tissue, as can be done by producing porous materials by techniques like powder metallurgy (PM). Stress shielding problem is the most important biomechanical problem of titanium (Ti) implants for bone replacement. As consequence, there is always a risk of bone resorption and subsequent implant loosening and/or bone fracture. Development of porous Ti implants has been widely explored as a plausible alternative to address this issue during last decade [1].
