  • Process for the polishing of metallic dental prostheses
    Patent number: 8444914
    Abstract: The invention concerns a process for the polishing of metallic dental prostheses, such as frames. In order to reproducibly obtain a defined surface roughness with no need for additional finishing, it is proposed for the dental prosthesis to be polished by means of plasma polishing.
    Type: Grant
    Filed: March 18, 2008
    Date of Patent: May 21, 2013
    Assignee: Degudent
    Inventors: Stefan Fecher, Martin Haizmann, Lothar Volkl, Lars Weisensel
  • Porous ?-SiC-containing ceramic molded article comprising an aluminum oxide coating, and method for the production thereof
    Patent number: 7867313
    Abstract: The invention concerns a process for the production of a porous ?-SiC-bearing ceramic molded body that includes an aluminum oxide layer at the surface of the pores and passages of the porous ?-SiC-bearing ceramic molded body. The invention further concerns a porous ?-SiC-bearing ceramic molded body which has pores of a mean pore size in the range of between 0.1 urn and 50 ?m and an aluminum oxide layer at the surface of the open pores and passages.

  • Molded porous ceramic article containing beta-SiC and process for the production thereof
    Patent number: 7648932
    Abstract: The invention relates to a process for the production of a molded porous ceramic article containing ?-SiC, which process comprises the following steps: the preparation of a molded article containing silicon and carbon and the subsequent pyrolysis and siliconization of the article containing silicon and carbon to form SiC. The invention further relates to a molded porous ceramic article containing SiC which has been produced from a molded article containing silicon and carbon.

  • METHOD FOR THE MANUFACTURE OF DENTAL PROSTHESES
    Publication number: 20080241788
    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.
