Amorphous Calcium Phophate Composites With Improved Mechanical Properties



Justin N. O'Donnell, Joseph M. Antonucci, Drago Skrtic


Young s Modulus, diametral tensile strength and water sorption. Mechanically milling the filler increased the volume of fine particles in the sample, resulting in a more homogeneous intra-composite distribution of ACP and a reduction in voids. In turn, less water diffused into the milled composites upon aqueous exposure, and they showed a marked improvement in biaxial flexure strength and a moderate improvement in flexural strength over composites with unmilled ACP. The demonstrated improvement in the mechanical stability of milled Zr-ACP composites may help in extending their dental applicability.
