Calcium phosphate cements have lots of advantages that make them proper choice for repairing bone defect, but their weak mechanical properties limites their usage in non-load bearing bon. In these research different percentages of nano-titania were added to the calcium phosphate cement and after soaking in human blood plasma their mechanical properties were investigated. X-ray pattern diffraction was used for phase analysis and investigating microstructure was done by scanning electronic microscopic (SEM). Before soaking, mechanical strength of cement sample was 3.12 MPa and by adding 10 wt. % nano-titania reached to 5.54 MPa and after soaking, adding nano-titania had positive effect on compressive strength. X-ray pattern diffraction showed adding nano-titania did not have any inhibition effect on hydroxyl apatite formation ability.
