Recent Developments of Bioactive Glass Electrophoretically Coated Cobalt Chromium Metallic Implants

Abstract

Coating surfaces with bioactive glass was identified as depositing fine bioactive glasses on biomaterial substrates. Cobalt chrome (Co-Cr) was a viable alternative to stainless steel for long-term applications with superior ductility. Their mechanical properties are explained with high-strength biomaterials for elastic models of 220 to 2300 GPa, more significant than the 30 GPa of bones. The goal of combining metals and bioactive glass has resulted in high biocompatibility and improved bioactivity of the implant’s surface. In addition, it triggers new bone tissue to regenerate throughout osteogenesis and mineralization. However, implantation failure still occurs and requires surgery revision due to a lack of adequate bone bonding and delamination at the coat’s surface layer of the implant. The current review summarizes the coating's adhesion between bioactive glass and Co-Cr substrate applied through Electrophoretic deposition (EPD).
