  • Patent number: 10814000
    Abstract: A guided bone regeneration material is disclosed. The guided bone regeneration material includes biodegradable fibers produced by an electrospinning 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.
    Type: Grant

  • Publication number: 20100119564
    Abstract: Disclosed is a guided bone regeneration membrane including a novel mechanism that effectively induces a bone reconstruction ability. The mechanism is provided by forming a bi-layered structure of a first nonwoven fabric layer containing a silicon-releasable calcium carbonate and a poly(lactic acid) as principal components and a second nonwoven fabric layer containing a poly(lactic acid) as a principal component; and coating the first nonwoven fabric layer with an apatite. The guided bone regeneration membrane is available by using a nonwoven fabric manufacturing technique through electrospinning and a simulated body fluid soaking technique.
