The acellular dermis membrane contains basement membrane on one of its surfaces. It can provide a dense and impenetrable layer against microorganism and pathogen penetration into deeper layers. So the membrane surface can stay exposed in high-perfused tissue of the oral cavity. The product origin is the collagen membrane (skin dermal layer), which consists of strong collagen type I and III fibers that strengthen the product, and also elastic fibers causing flexibility. This collagen membrane results in product's unique features.
