  • Publication number: 20140208980
    Abstract: The present invention relates to a manufacturing method for fibrous demineralized bone matrix, the method comprising: (a) a step for subjecting a bone, separated from a body, to a primary demineralization in an acid solution for 1-5 hours; (b) a step for slicing the bone obtained in step (a) to a thickness of 0.1-3 mm, thus forming a sheet of bone; (c) a step for subjecting the sheet of bone obtained in step (b) to a secondary demineralization in an acid solution for 2-6 hours; and (d) a step for grinding the demineralized bone obtained in step (c).

  • Publication number: 20140044966
    Abstract: This invention relates to whitlockite and a method for manufacturing the same. The method includes adding, to water, a calcium ion supplying material and a cation supplying material containing a cation (X) other than the calcium ion to prepare a cation aqueous solution, adding a phosphoric acid supplying material to the cation aqueous solution, and aging the cation aqueous solution including the phosphoric acid supplying material. As a result, whitlockite having high purity and high crystallinity can be mass produced using a simple process.

  • Patent number: 8277848
    Abstract: Disclosed herein is a method for preparing an aqueous solution of high-concentration calcium phosphate, the method comprising the steps of: preparing an acidic aqueous solution using an acidic chelating agent; and dissolving a calcium phosphate-based compound in the acidic aqueous solution, and then adding a pH-adjusting agent to the acidic aqueous solution to adjust the pH of the acidic aqueous solution. The disclosed aqueous solution does not form a precipitate after neutralization so that it can be used in various calcium-containing products, including foods, drugs, or quasi-drugs.

  • Publication number: 20120093895
    Abstract: The present invention relates to a bone-repair composition comprising a micro-pulverized demineralized bone matrix; a nonmicro-pulverized demineralized bone matrix; and a hydrating material. The bone-repair composition of the present invention provides easier injectability and shape-maintenance (handling), and exhibits excellent bone-repairing effects due to a large surface area of the micro-pulverized demineralized bone matrix and an early release of the bone growth factors, compared with conventional compositions comprising the nonmicro-pulverized demineralized bone matrix alone. It also has an advantage of being biocompatible and harmless to the human body because there is no use of synthetic materials.
