PREPARATION METHOD OF POROUS BETA TRICALCIUM PHOSPHATE GRANULES

摘要

Disclosed relates to a preparation method of ß-tricalcium phosphate granules and, more particularly, to a preparation method of spherical porous ß-tricalcium phosphate granules using tricalcium phosphate precursors, porous precursors, gelatin solution and dispersion medium. The preparation method of the present invention prepares ß-TCP granules and uses a dispersion medium to promote the gelation, differently from other methods. The ß-TCP granules prepared containing micropores and macroporoes all together have a biocompatibility. Accordingly, the ß-TCP granules grafted in vivo stimulate the new bone formation by acting as a frame, into which new osseous tissues grow to enter, not causing an immunological reaction, thus being effectively used as a bone graft material or a bone scaffold.
