In this work, mechanical properties of α-tricalcium phosphate (α-TCP)-tetracalcium phosphate (TTCP)-dicalcium phosphate dehydrate (DCPD) system bone cement, was studied. This research examined the effect, which it follows in particle size distribution change of starting materials. The composition of α-TCP/TTCP/DCPD system bone cement was fixed Ca/P=1.50. 20 groups of cement were prepared with the particle size distribution. The highest compressive strength of the specimen(P/L ratio=2.5) after curing 7 days in simulated body fluid(SBF) was 60±2 MPa. That particle size distribution of the highest compressive strength was 10.33 μm(α-TCP=9.7 μm, TTCP=6.73 μm and DCPD=16.02 μm).
