DEMINERALIZED BONE GRAFT SUBSTITUTE AND ITS PROCESS

摘要

PURPOSE: A bone graft material and a method of manufacturing thereof are provided to provide the bone graft material at low price and to be stable. CONSTITUTION: A manufacturing method of a bone graft material comprises the following steps: consecutively washing a bone tissue by using hydrogen peroxide, ethanol and sterile pure water; sterilizing the bone tissue by irradiating radiation; separating trabecular bone from the sterile bone tissue and pulverizing thereof; removing lipid and immunogen by consecutively applying chloroform: methanol mixed solution, hydrogen peroxide and ethanol to the pulverized trabecular bone; sorting the manufactured trabecular bone powder by size; and freeze-drying the selected trabecular bone powder.
