What is special about the Jason® membrane? Why does it extend the indication range in comparison with softer and thicker collagen membranes?
The botiss Jason® membrane is a very thin, but tear-resistant membrane derived from porcine pericardium. In the animal, the tissue is exposed to a lot of strain and stress. This has a high impact on the natural morphology and multi-directional orientation of the collagen fibers, which is retained during processing. Just as the more angiogenic membranes derived from porcine dermis (e.g. collprotect® membrane by botiss biomaterials), the Jason® membrane consists of native collagen type I and III (3). It integrates ideally into the tissue and has shown inflammation-free biodegradation (3, 4). This is an important difference to chemically cross-linked collagen membranes: their longer barrier function is based on a biochemical alteration of the collagen matrix, which affects the collagen structure (5).
Last but not least, due to its specific morphology, the Jason® membrane ensures a long barrier function (3). This permits sufficient separation of the cortical and trabecular bone compartments and bone formation extending to the outline of the grafted area. The membrane has a minimal thickness of only approximately 0.15 mm. This makes it easier and less invasive to close the soft tissues after augmentation, especially in comparison to expensive double-layer techniques – which are moreover used with voluminous bilayer membranes.
