Biofunctionalization of porous titanium coatings through sol-gel impregnation with a bioactive glass-ceramic

► Bioactive glass-ceramic coating for an improved osseointegration of porous Ti. ► Four-component bioactive glass composition through all-alkoxide sol-gel synthesis. ► Thin bioactive glass-ceramic layer on internal pore surface of porous Ti coating. ► High strength adhesion of composite porous Ti/bioactive glass-ceramic coatings on Ti.
