Nowadays, bone defect has become one of the most important disease which threat people's living quality severely. Today, the most common methods used to healing bone defects include: Autogenous bone grafts and allogenic bone grafts. But autogenous bone grafts have a shortage on donor, difficult to make shape and will bring a complicate disease on donor site; allogenic bone grafts often follow with graft rejective reaction, and have a potential risk of propagation of many disease.

目前，主要应用于临床骨缺损修复的方法有自体骨移植和异体骨移植等，但自体骨移植存在材料来源有限、供骨部位的损伤以及塑形困难等问题；异体骨移植也有潜在的疾病传播隐患以及移植排斥反应等严重后果，因此无论自体骨移植还是异体骨移植均无法完全满足需求，临床急需寻找一种安全有效的骨移植替代材料。
