Characterization and Monitoring of Titanium Bone Implants with Impedance Spectroscopy
(MDPI, 2020-08)
Porous titanium is a metallic biomaterial with good properties for the clinical repair of cortical bone tissue, although the presence of pores can compromise its mechanical behavior and clinical use. It is therefore necessary ...
