Calcium phosphate hydroxyapatite precursor and methods for making and using the same

(57) It indicates as summary orthopedics, dental cement, and a re-calcification agent especially about a useful and peculiar calcium phosphate composite, directions for use and a use kit, and the output obtained as a result. Although this composite contains phosphoric acid 4 calcium which calcium and the ratio of Lynn prepare from the mixture which is less than two, or it is substantially prepared under anhydrous conditions before use, and is maintained, it is desirable that they are the both. If it hardens, it will be substantially converted into a ヒドロキシ apatite after that, and if a new composite is transplanted where a living body tissue is contacted, it is absorbed gradually substantially, replaces a bone and offers a clear advantage about strength of cement, cure time, reliability, and other characteristics.
