Abstract

Replacement of apatite cement (AC) to bone is still controversial issue. To understand factor that could affect the replacement of AC to bone, AC consisting of an equimolar mixture of tetracalcium phosphate (TTCP; Ca ₄(PO₄)₂O) and dicalcium phosphate anhydrous (DCPA; CaHPO₄) was allowed to set at 37°C and 100% relative humidity under 5% CO₂ or N₂. Carbonate apatite (CO ₃Ap) was formed when AC was allowed to set under 5% CO₂. The amount of CO₃ decreased gradually as the depth from the surface increased. The CO₃Ap was the B-type CO₃Ap in which CO ₃^2- was replaced with PO₄^3- and the CO₃Ap found in bone. Larger amount of TTCP remain unreacted when the AC was allowed to set under N₂ whereas smaller amount of TTCP remain unreacted when the AC was allowed to set under CO₂. This may be caused by the larger Ca/P molar ratio of CO₃Ap. Formation of CO ₃Ap and/or small unreacted TTCP are thought to be key factors for the replacement of AC to bone.
