OMNIPORE implants are manufactured from a linear form of high-density polyethylene. Polyethylene has a long history of use in surgical implants. OMNIPORE Surgical Implants allow for tissue ingrowth because of its interconnecting open pore structure. The firm nature of the material allows carving with a sharp instrument without collapsing the pore structure. OMNIPORE Surgical Implants in blocks, sheets and preformed anatomical shapes are intended for augmentation and restoration of the craniomaxillofacial skeleton.
