Abstract
A fiber glass is provided for filling in a defect or hollow portion of bone. The fiber glass comprises calcium phosphate as a main ingredient and has a negative zeta potential. The calcium phosphate has a molar ratio of Ca/P of not less than 0.2 and less than 0.6 and the total content of CaO plus P.sub.2 O.sub.5 less than 80 wt %. The fiber glass is of long filament form or staple fiber form. The fiber glass of long filament form may be woven to form a woven filler.
Claims16
A fiber glass for filling in a defect or hollow portion of bone, said fiber glass having a negative zeta potential and containing calcium phosphate having a molar ratio of Ca to P of not less than 0.2 and less than 0.6, and the total content of CaO plus P.sub.2 O.sub.5 in the fiber glass, based on the weight of the fiber glass, being not less than 80% by weight, the surface of the fiber glass being coated with a calcium phosphate compound.
