    摘要: The present invention relates to a membrane for guided bone tissue regeneration and, more particularly, to a membrane for guided bone tissue regeneration having a structure that silk fibroin nanofibers obtained by removing sericin from silk fibers are formed as a nonwoven, and a manufacturing method thereof.A membrane for guided bone tissue regeneration according to the present invention has a predetermined strength, biocompatibility, and biodegradability, and may maintain a sustained drug release system, when drugs are added in the manufacturing process. Additionally, a membrane for guided bone tissue regeneration according to the present invention may be modified corresponding to the condition of usage, because a thickness of the membrane may be adjusted by controlling fineness of nanofibers, compactness of nanofibers, and pore size of a multiporous structure may be adjusted, in a nonwoven manufacturing process. A nanofibrous membrane for guided bone tissue regeneration according to the present invention is manufactured by freezing rapidly, drying a silk fibroin solution obtained by removing sericin from silk fibers, and by electrospinning after dissolving the dried silk fibroin in an electrospinning solvent. The membrane according to the present invention has excellent adhesion and air permeability, and is thereby effective in regeneration of damaged periodontal tissues.
