Abstract
Abstract In vitro chemical stability and bioactivity of three different cement type bone substitutes were determined by incubating cement samples in the simulated body fluid (SBF) for 7 and 28 days. Morphology of sample surfaces has been studied using scanning electron microscopy (SEM) combined with an energy dispersive X-ray spectroscopy (EDS) and by atomic force microscopy (AFM). The diffuse reflectance Fourier-transform infrared spectroscopy (DRIFTS) was applied as a supplementary method. The development of bone-like apatite layers on the surface depended on their initial phase composition. Obtained cements showed good surgical handiness, high bioactive potential and were chemically stable. They seem to be promising materials for bone substitution.
