Osteoconductive coating of implants made of plastic
The invention relates to biomaterials based on plastics, such as polyaryl polyether ketone (PEK), and to methods for producing and using same. The following describes how a mechanically stable coating made of a porous bone substitute material, e.g. Nano Bone®, is applied to polyaryl polyether ketone (PEK), e.g. polyether ether ketone (PEEK), as a result of which the problem of poor cell adhesion on plastics surfaces of this kind can be solved. The bone substitute material can be applied both dry as a powder and also in a wet spraying method. The coating is a result of briefly melting the polymer surface and the resulting partial penetration of the previously applied layer. In the process, the molten polymer penetrates into nanopores of the bone substitute material and thus establishes a firm connection.
