Deproteinization filler and cartridge containing same

摘要

A deproteinization filler comprises an aggregate of hydroxyapatite fibers having a three dimensional network structure. The mean radius of pores defined by the aggregate is approximately 0.02 mu m to approximately 0.08 mu m, the specific surface of the aggregate is approximately 25 m2/g to approximately 65 m2/g and the mean diameter of particles defined by the aggregate is approximately 1 mu m to approximately 30 mu m. The filler is produced by a given method. The filler may be contained in a throwaway cartridge.
