BIOMATERIAL AGGREGATE/CEMENT COMPLEX, AND CEMENT CURED BODY

摘要

PROBLEM TO BE SOLVED: To provide a biomaterial aggregate/cement complex, and a cement cured body, or the like.

SOLUTION: In the aggregate particle/cement complex containing biocompatible material aggregate particles, (1) the aggregate particles are made of calcium phosphate ceramics or biodegradable plastics; (2) the particle diameter of the aggregate is from 151 μm to 5 mm; (3) the quantity of contained aggregate particles in the cement is from 51 to 90 vol%; and (4) the cement is a self-curing type calcium phosphate cement. An infusion/filler for organisms is made of the aggregate particle/cement complex. A tube-filled object consists of the infusion/filler filled in a tube whose one end or both ends are closed. An infusion filling material spouting device consists of an outlet formed in a part of the tube-filled object. The cement cured body is made by hydrating and curing the cement part of the aggregate particle/cement complex. A method for controlling mechanical characteristics of the self-curing type calcium phosphate cement hydrating/curing body is adding the biomaterial aggregate particles to the self-curing type calcium phosphate cement by 51-90 vol%.
