磷酸钙骨替代材料是表面活性类材料,主要有羟基磷灰石和磷酸三钙。在修复骨缺损应用中的明显优点是能起骨生长引导作用,并与骨形成直接骨性界面结合,这种结合被认为是化学性结合,结合机制与材料植入后其表面沉积的生物性钙磷结晶层形成有关。骨性界面受材料的化学构成和结构、金属掺杂物、植入体移动等因素影响。 Calcium phosphate bone substitute materials are surface active materials, mainly hydroxyapatite and tricalcium phosphate. The obvious advantage in repairing bone defects is the ability to act as a guide for bone growth and to bind directly to the bone to form a bone interface that is thought to be chemically bound and that the binding mechanism and the biological Calcium phosphorus crystal layer formation related. Bone interface by the chemical composition and structure of the material, metal dopants, implant movement and other factors.
