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.
