摘要

The present invention particularly relates to a calcium phosphate composition useful as an orthopedic and dental cement and remineralizing agent, a method for producing the calcium phosphate composition, and a kit using the same. The composition comprises a mixture of calcium phosphate and at least one other soluble calcium phosphate which may be prepared from a mixture of one or more sources of calcium, phosphoric acid and oxygen having a ratio of calcium to phosphoric acid of 2 or less, Is prepared and maintained under substantially anhydrous conditions prior to contacting with the aqueous medium in combination with the calcium phosphate compound. These calcium phosphates are hardened with hydroxyapatite at setting, can gradually dissolve substantially gradually, can replace bone when implanted in contact with living body tissue, and have other advantages, such as cement strength, cure time and certainty, and /RTI
