Effect of FA on bioactivity of bioactive glass coating for titanium dental implant. Part I: Composite powder

► Fluorapatite crystals improve glass bioactivity. ► Fluorapatite crystals act as nucleation sites for growing of new crystal phases. ► MgO concentration has an effect on the fluoride released. ► Magnesium has an impact on glass dissolution and bioactivity. ► Glass dissolution is required for apatite growth.
