In this work, a simple protocol based on electrical impedance measures is implemented to detect changes on chemical composition, the microstructure (percentage and size of pores) and the surface modification treatments of metallic implants. The Hewlett-Packard 4395A Agilent impedance analyzer was employed for these measurements. Discs of...

Commercially pure titanium (c.p. Ti) and Ti6Al4V alloys are the most widely used metallic biomaterials in the biomedical sector. However, their high rigidity and the controversial toxicity of their alloying elements often compromise their clinical success. The use of porous β-Titanium alloys is proposed as a solution to these issues. In this...

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 characterization of the macroporosity inherent to the manufacturing process and the effect of the surface treatment with...
