<p>A hard-tissue repair composition comprising a paste (A) containing an inorganic powder of calcium phosphate, a polymerizable monomer mixture and a polymerization initiator and a paste (B) containing an inorganic powder of calcium phosphate, a polymerizable monomer mixture and a polymerization accelerator, wherein the content of the inorganic powder in each paste is 75-85 wt. % and each monomer mixture contains monomers represented by general formulae (1) and (2), the content of the monomer (1) accounting for 40-65 wt. % of the monomer mixture as a whole. The composition can well adhere to the bone and has a sufficient water resistance. As it generates little heat upon hardening, it is less detrimental to the patient's tissue. Furthermore, as the paste has an appropriate consistency, the supply unit of the invention facilitates homogeneous mixing of the pastes and application of the resultant mixture to the affected part. Thus this composition can be used not only as a bone cement but also as a filler for the defected part of the bone, a bone prosthesis, or an artificial bone.</p> |
