Abstract
A foil or membrane for covering bone defect locations and for promoting bone regeneration, comprised of titanium and which is inelastic, stress-free and plastically deformable. The foil has a thickness of less than 0.1 mm. The thickness lies especially in a range of 0.025 mm. It is advantageously roughened at least on one surface or grooved. Cut pieces have a cut burr which projects from one surface and in the use of the foil, turned to the bone with sealing edges. A method of making such a foil with the aforesaid characteristics comprises a removal of the surfaces of the rolled foil by a chemical foil until the desired thickness is reached. A nail for fixing the foil in position has a spherical shaped head and in its concavity merges with a saw-tooth barbed pin with a radius.
