摘要

Microstructured porous calcium phosphates (CaP) not only support bone formation in orthotopic sites but can also give rise to bone formation in ectopic or non-osseous sites. One explanation for this osteoinductive behaviour is that the enlarged surface area allows the binding of high concentrations of proteins such as BMPs. If in vivo concentration of proteins is a true mechanism of ectopic bone formation, materials other than CaP may also have osteoinductive properties provided that they have an enlarged surface area (micropores) and can bind similar proteins.To test this hypothesis, we compared the ability of hydroxyapatite (HA), TiO_2 ceramic and Al_2O_3 ceramic to absorb various proteins and evaluated the osteoinductive capacities of these materials after intramuscular implantation in canines.
