Studies on novel bioactive glasses and bioactive glass–nano-HAp composites suitable for coating on metallic implants
Source abstract
Abstract
Abstract A series of novel zinc oxide (ZnO) containing bioactive glass compositions in SiO2–Na2O–CaO–P2O5 system and composite with hydroxyapatite (HAp) nano-particles were developed and applied as coating on Ti–6Al–4V substrates. The bioactive glasses and their composites were also processed to yield dense scaffolds, porous scaffolds and porous bone filler materials. The coating materials and the coatings were characterized and evaluated by different in vitro techniques to establish their superior mechanical properties. The cytotoxicity test of the coating material, porous and dense scaffolds and coated specimens showed non-cytotoxicity, biocompatibility and promising in vitro bioactivity for all tested samples. The dissolution behaviour studies of the bioactive glasses and the composites in simulated body fluid showed promising in vitro release pattern and bioactivity for all tested samples. Addition of nanosized HAp improves mechanical properties of the bioactive glass coating without affecting the in vitro bioactivity.
