Abstract

A guided bone regeneration material is disclosed. The guided bone regeneration material includes biodegradable fibers produced by an electro spinning method. The biodegradable fibers produced by the method include a silicon-releasing calcium carbonate and a biodegradable polymer. The silicon-releasing calcium carbonate is a composite of siloxane and calcium carbonate of vaterite phase. The biodegradable fibers may be coated with apatite. When the guided bone regeneration material is immersed in a neutral aqueous solution, silicon species ions are eluted from the calcium carbonate. The guided bone regeneration material excels in bone reconstruction ability.

Description

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This is a continuation-in-part application of U.S. application Ser. No. 12 / 591,258 filed on Nov. 13, 2009, which claims the priority of Japanese Patent Application No. 2007-231621, filed on Sep. 6, 2007. The disclosures of these prior applications are incorporated by reference in their entireties.FIELD OF THE INVENTION

[0002] The present invention relates to a guided bone regeneration material and a manufacturing method thereof. The guided bone regeneration material is used in a guided bone regeneration (GBR) technique which is a technique for repairing bone defects and is widely used in the field of oral surgery and maxillofacial surgery.RELATED ART OF THE INVENTION

[0003] Guided bone regeneration membrane is a masking membrane that covers bone defect areas so as to prevent invasion of non-osteogenesis-contributing cells and tissues into the bone defect areas and to allow the bone to reconstruct by taking full advantage of the self-regenerat...
