Kind Code:
B2
Abstract:
PURPOSE:To obtain a cement for living body with excellent affinity to the living body which can be filled at an arbitrary location. CONSTITUTION:This cement comprises a powder agent mainly composed of a mixture of an alpha type third calcium phosphate and a first calcium phosphate so arranged to be 1.40-1.498 in Ca/Pmol ratio and a liquid agent and moreover, the powder agent contains 0.1-5wt.% apatite whisker per the total amount thereof and also, does second calcium phosphate. The calcium phosphate cement for living bodies uses the calcium phosphate cement of a specified composition rich in affinity to organisms and the apatite whisker as base material and hence, it has a high strength while being limited in strength variations with excellent affinity to the living bodies. Also excellence in fluidity and operability in kneading allows filling at an arbitrary location such as a part with a compplicated from or a narrow part.
