Through the demineralization process by which the inorganic matter in bone is removed to a certain ratio, growth factors like bone morphogenetic proteins(BMP), which assist in bone repair, are released, increasing osteoinduction and contributing to faster and higher quality bone repair.
When a highly viscous water-soluble composite is added to this bone powder, the product gains high viscosity. Without requiring extra rehydration, the product can be immediately molded to the desired shape, or mixed with other powder bone. The highly viscous water-soluble composite assists in the action of BMPs released from the demineralized bone and prevents reduction in the particle size of demineralized bone, collagen decomposition, and breakdown of growth factors during radiation sterilization, which contributes to higher quality bone repair. Such a product is called Demineralized Bone Matrix(DBM).
