Abstract: A composition for use as a bioactive bone cement having a powder component including strontium-containing hydroxy apatite and formulated to create a settable fluid substance when mixed with a liquid component. The liquid component includes a Bisphenol A diglycidylether dimethacrylate resin which when mixed with the powder component creates a bioactive bone cement. The bioactive bone cement can alternatively be in the form of a two paste component system in which a first paste component including strontium-containing hydroxy apatite, Bisphenol A diglycidylether dimethacrylate resin and a polymerization initiator is formulated to create a settable paste substance when mixed with a second paste component. The second paste component includes strontium-containing hydroxy apatite, Bisphenol A diglycidylether dimethacrylate resin, and a polymerization accelerator which when mixed together with the first paste component creates a bioactive bone cement.
