Resorption Rate of Calcium Sulfate Bone Fillers Adjusted by Incorporation of Hydroxyapatie

Abstract:

Calcium sulfate/hydroxyapatie (CaSO4/HA) composite bone fillers were fabricated through molding method. Their structure and properties were characterized by infrared spectroscope, scanning electronic spectroscope, x-ray diffraction and degradation test. The results show that HA crystals were attached to the CaSO4 crystals and prevented the growing of sulfate crystals. So their size is shorter than that of CaSO4 crystals prepared from pure CaSO4 semihydrate, and some even had defect. The resorption rate of CaSO4 bone fillers was decreased when HA was incorporated.
