Title:
COMPOSITE COLLAGEN MEMBRANE IN WHICH COLLAGEN LAYERS HAVING DIFFERENT BIODEGRADATION RATES ARE LAYERED, AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/031776
Kind Code:
A1
Abstract:
The present invention relates to a dental composite membrane in which a plurality of collagen layers having different biodegradation rates are layered so as to be used in bone regeneration or bone grafting, and a production method therefor, and relates to an absorbent composite membrane for inducing the regeneration of periodontal tissues, the membrane being capable of maintaining, for a desired period of time, a function for ensuring sufficient space for bone formation and a function for effectively block soft tissues and various bacteria, and being rapidly degraded in the body after the bone is completely regenerated.
