Apatite-forming ability of bioglass coated bovine bone scaffolds

Abstract

The aim of this study was to investigate the bone-like apatite forming ability of bioglass coated bones by immersing them in simulated body fluid (SBF). Various types of bioactive coatings with an average thickness of 15 ?m were deposited on the surface of the cortical bovine bone by vacuum assisted infiltration.More intense apatite crystallization was observed using additives such as hydroxyapatite, sintered bone and ?-whitlockite in the base glass. The dissolution properties of the scaffolds were determined by ICP-OES and XRF methods. The consequence of the release of Ca and P during immersion in SBF on the mechanical properties was observed through measurements of microhardness, bending and compressive strength.
