Comparative bone growth behavior inter-spaces of granules of bioglass, aw glass ceramics and hydroxyapatite

摘要

Three kinds of bioactive particles of 45S5 Bioglass~circleR, synthetic hidroxyapatite and A-W glass ceramic were implanted into 6 mm diameter holes made in the femoral condyles of mature rabbits. Bone-ingrowth rate was measured by means of an image processor for analytical pathology. 45S5 Bioglass~circleR led to the most rapid bone proliferation, and at later periods found to be more resorption than A-W glass ceramic though synthetic hydroxyapatite was not resorbed.
