摘要： The invention provides a process for producing a metal body, which leads in a simple and reliable way to formation of a defined surface topography, if desired also combined, in the range from 10 nm to 500 μm on a metal base body or blank which is to have, in particular, nanoscale pores. For this purpose, a pulsating current is applied to a metal base body in an electrolysis bath, with the electrolysis bath comprising salt former ions matched to the material of the metal base body. Furthermore, the invention provides a dental implant having particularly advantageous surface properties, in which a nanostructure is superimposed on a surface microstructure and nitrogen atoms and/or nitrogen compounds are attached and/or included in the region of the surface.

摘要： The invention relates to a bioceramic coated apparatus and method of forming the same. The apparatus may be a medical implant such as, for example, an orthopedic implant or a dental implant. The bioceramic coating is designed to increase tissue and/or bone growth upon implantation of the apparatus. The apparatus has a valve metal substrate having a nanoporous valve metal oxide surface layer. The nanoporous surface layer contains a plurality of nanopores. The nanopores have adsorbed phosphate ions on at least their interior surfaces. A bioceramic coating is formed on the nanoporous surface and anchored into the nanopores. Optionally, the nanopores are formed into a tapered shape in order to increase adhesion to the bioceramic coating.

摘要： A gold-plated, full porcelain-coverage crown and a method to create that crown. The crown may be formed from a metallic coping mimicking the shape of the human tooth, such as one made from a nickel-chromium alloy. The intaglio of the crown is plated in gold. The exterior of the crown is covered in a ceramic material such as porcelain, and the interior of the crown or intaglio is plated in gold, and together this prevents exposure of the metallic alloy to the patient's mouth. The crown may be used for patients with an allergy to alloys such as nickel-chromium. Additionally, the crown is useful because it is affordable, contains only a small amount of gold, and is aesthetically pleasing.
