  • Composition for promoting bone regeneration and restoration
    Patent number: 8192751
    Abstract: A bone grafting material composite is provided. The bone grafting material composite includes a demineralized bone matrix (DBM) and a carboxymethyl cellulose (CMC)/glycerol gel carrier. Due to the CMC/glycerol gel carrier, the implantation ability thereof is better than that of the DBM. Therefore, the bone grafting material composite can be easily used, so that a curative effect can be greatly improved. In addition, since the CMC/glycerol gel is used as a carrier, the composite with a mobility maintained is washed out by water after surgery, so that the composite can be fixed on a damaged portion of a bone.
    Type: Grant
