Apatite-forming ability of PMMA bone cement containing anatase nanoparticles

Abstract

Preparation of anatase nao-particle containing PMMA bone cements was attempted and apatite-forming abilities and mechanical properties of the resultant cements were examined. All the examined cements formed apatite on their surfaces within 1 d in SBF. Their apatite-forming abilities were increased with increasing particle amount and decreasing particle size. Bending strengths of the present cements were smaller than that of PMMA cement, and approximately half of that of glass-ceramic A-W-containing cement.
