Abstract
Disclosed is a hardening material comprising (a) a powder component composed of a powdery mixture of tetracalcium phosphate and calcium phosphate having a Ca/P atomic ratio lower than 1.67 and (b) a liquid component composed of a colloidal aqueous solution comprising solid colloid particles dispersed in an aqueous medium, wherein said components (a) and (b) are independently packed and both the components are mixed for hardening. This hardening material can give a hardened body having a high strength without showing any harmful action on a living body. Accordingly, this hardening material is especially effectively used for the restoration of a hard tissue of a living body.
