Abstract
The present invention provides a kind of bone tissue filling material. Spongy bone of ox is first treated to become inorganic matter, soaked in sodium pyrophosphate solution, dried and high temperature calcined to produce calcined bone tissue filling material. The filling material is soaked in suspension of zinc chloride, dried and high temperature calcined to obtain the zinc-containing calcined porous bone tissue filling material. The porous bone tissue filling material has low cost, good biocompatibility, homogeneous and communicated pores, certain mechanical strength, capacity of promoting bone growth and other features, and is suitable for filling bone deficiency, spinal column fusion and cell rack in bone tissue engineering, etc.
