Abstract
Cover device for temporarily covering bone voids, particularly a recess, which are filled with ossiferous material such as hydroxyl apatite granules, in the proper bone tissue of the body, comprises a perforated reinforcement element for covering the void in essentially a shape-stable fashion that is composed of relatively stiff but flexible material such as a supporting grid of metal or the like, and a single-layer or multi-layer cover membrane carried by the reinforcement element, and at least one of the layers of the cover membrane is applied as a solution film onto the reinforcing element after the use-specific shaping of the element as well as a method for the production of the element.
