METHOD FOR PRODUCING IMPLANTS WITH AN ULTRAHYDROPHILIC SURFACE

摘要

The procedure for the production of storable metal implant with an ultrahydrophilic surface, comprises treating the surface of the implant with oxidation agent to form an oxidation layer on the surface of the metal until a contact angle hysteresis of less than 0.5[deg] arises during treating the surface of the implant with water or until the contact angle hysteresis lies in the area of minimum in diagram during the application of the contact angle hysterisis against the time period of the oxidation treatment or treating the surface of the implant with chromium-sulfuric acid. The procedure for the production of storable metal implant with an ultrahydrophilic surface, comprises treating the surface of the implant with oxidation agent to form an oxidation layer on the surface of the metal until a contact angle hysterisis of less than 0.5[deg] arises during treating the surface of the implant with water or until the contact angle hysteresis lies in the area of minimum in diagram during the application of the contact angle hysteresis against the time period of the oxidation treatment or treating the surface of the implant with chromium-sulfuric acid with a density of greater than 1.40g/cm over a period of 0.5-1 hour at 200-250[deg] C. The implant consists of metal and/or metal alloy with ceramic material. A saline water solution that is inert against the ultrahydrophilic surface consists of a total ion concentration of more than 0.5 mol/liter and surrounds all sides of the implant. The implant in the saline water solution brings in a carrier packaging, which locks in gas and liquid tight manner. The saline water solution vaporizes for drying and uses in a quantity and with a salt concentration that forms a salt layer covering all sides of the implant with a layer thickness of 1-500 mu m after the vaporization. The implant is sterilized with electromagnetic radiation. Independent claims are included for: (1) a storable implant; and (2) a method for loading the surface of the implant with peptides and bone growth factors.
