Thermal, Structural, Morphological and Electrical Characterization of Cerium-Containing 45S5 for Metal Implant Coatings

Biomaterial coatings on dental implants are increasingly being used as a solution to the problems of rejection and implant loss. Bioglass® has been seen promising material for coating metal implants, increasing integration rate improving bond between bone implant. Multifunctional bioactive glasses can exhibit antibacterial, antitumor antioxidant effects with addition therapeutic ions. The cerium ion shown an effect through mimicking mechanisms by acting scavenger reactive oxygen species (ROS), which is important avoiding oxidative stress post-surgery. Furthermore, it possible store electrical charge bioglass surface, potentiates osseointegration. In this work, various percentages oxide (0.25, 0.5, 1 2 mol%) were developed structurally electrically analyzed. It was verified that insertion did not modify amorphous phase characteristic glass but showed increase in number non-bridging oxygens (NBOs). This NBOs conductivity either ac or dc regime. similar permittivity values also suggest their storage ability unchanged CeO2. Concerning impedance spectroscopy (IS) data, decrease resistance visible oxide, suggesting favorable behavior applications electro-Fenton reaction.
