  • Patent number: 9925306
    Abstract: The present invention relates to a carrier for growth factor related to regeneration of bone tissues that is capable of arbitrarily controlling the delivery rate of growth factors related to bone regeneration and thus especially applicable to a bone void filler in the fields of the dental or orthopedic applications. The carrier for controlling the delivery rate of the growth factor in the present invention is composed of a hyaluronic acid hydrogel having a distribution of interconnected pores and a calcium phosphate microsphere being distributed in the pores of the hyaluronic acid hydrogel. The calcium phosphate microsphere having a porosity suitable for delivery of the growth factor is positioned into the pores of the cross-linked hyaluronic acid hydrogel to complete the carrier.

  • 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.
