Abstract

The biological response of strontium (Sr) doped hydroxyapatite (HA) and hydroxyapatite-zirconia (HA-ZrO2) composites produced by employing sol-gel technology, minimal ZrO2 loadings, and novel microwave-sintering regimes thereby retarding decomposition, is reported. In vitro evaluations indicate that all materials induce a favorable response from rat osteosarcoma cells. In vivo evaluations show osteoconductivity and biocompatibility for both the Sr-HA and HA-ZrO2. The materials did not cause any inflammatory response in bone. The Sr-HA displays better biocompatibility which may be due to the incorporation of Sr and the formation of a surface apatite layer.
