Abstract
The present disclosure is directed to a titanium dioxide scaffold provided with a nanoporous outer layer which can function as a cortical wall, inhibiting growth of soft tissue into the scaffold and increasing its mechanical strength. The disclosure is also directed to a process for producing such a nanoporous outer layer and the application of the titanium dioxide scaffold with the nanoporous outer layer as a medical implant.
