[Possibilities for improvement of the surface properties of dental implants (2). The use of ceramic oxides in surface coating for titanium and tantalum implants].

A corrosion-resistant, 2000-2500 A thick, ceramic oxide layer with a coherent crystalline structure was produced on the surface of titanium implants. The layer contains a bioactive component, it is made from the material of the implant, adheres well and gives an aesthetically pleasant impression. The coated implants were subjected to various physical, chemical electronmicroscopic, etc. tests for their qualitative characterization. These tests demonstrated the good properties of the implants. The procedure is protected internationally by patents.
