Uses: Guided tissue regeneration
Collagen-based membranes have been used in periodontal and implant therapy to promote the growth of specific types of cell. In oral surgery, barriers can be used to prevent fast-growing cells of the gingival epithelium migrating to a wound in a tooth, preserving space there for tooth cells to potentially regenerate.
The benefit of using collagen-based membranes for this purpose, in addition to collagen's healing qualities, is that they can be made to be resorbable(the body breaks down the collagen and assimilates the protein over time). This means that patients do not require a second surgical procedure to have the barrier removed.
