The purpose of this study was to prepare amorphous nano-hydroxyapatite fillers by sol-gel method and incorporating the prepared fillers into traditional PMMA bone cement to test the compressive strength of amorphous nHA/PMMA composite. The prepared fillers were characterized by XRD, FT-IR andTEM. We prepared composite specimens containing 20 wt% amorphous nHA in PMMA, then tested their compressive strength using universal testing machine. This experiment proved that the mechanical property of the prepared novel composites is satisfactory to be used as bioactive bone filler material. In particular, the 20 wt% nHA composite can be used as bioactive bone filler alternative to traditional PMMA
