Abstract
The invention relates to the use of a cobalt-chromium alloy in the manufacture of a dental prosthesis. The alloy contains: 43-68% by weight cobalt, 12-30% by weight chromium, 8-25% by weight tungsten, 0-13% by weight iron, 0-30% by weight manganese, 0-10% by weight molybdenum, 0-5% by weight of at least one of the elements aluminum, tantalum, rhenium, titanium and less than 0.1% by weight carbon. A dental prosthesis with favorable workability and a low corrosion rate is obtained by manufacturing the dental prosthesis by means of a laser melting and/or sintering process.
