  • Desktop process for producing dental products by means of 3-dimensional plotting
    Patent number: 6939489
    Abstract: A process for fabricating dental form pieces for dental restoration and replacement parts is provided and includes the step of applying a material, on a firm support or a fluid medium, by a three dimensional plotting technology in a layer by layer manner. The material has micro cords and/or micro drops which include at least one of a meltable, polymerizable, polycondensable, and polyaddable constituent element that is an unfilled monomer, a reinforced monomer, oligomer, polymer, or a ceramic element. The process also includes the step of hardening the applied material by cooling of the material, chemical reaction, polymerization with thermal handling, or polymerization by irradiation of the material with UV or visible light.
    Type: Grant
    Filed: March 25, 2002
    Date of Patent: September 6, 2005
    Assignee: Ivoclar Vivadent AG
    Inventors: Norbert Moszner, Armin Burgath, Rolf Mulhaupt, Ulrich Salz, Volker Rheinberger, Rudiger Landers
  • Low shrinking polymerizable dental material
    Publication number: 20040229972
    Abstract: The invention describes a low shrinking polymerizable dental material, comprising a mixture of a polymerizable resin, a polymerizable monomer, a polymerization initiator and/or sensibilizer and a filler in a content of about 20 to about 85 percent. The volumetric shrinkage during polymerization is less than about 1.5 Vol.- % due to its rheopex behavior.

  • Thermochromic dental material
    Patent number: 6670436
    Abstract: The invention relates to dental materials which contain a thermochromic dye and which display a reversible change of colour in the event of changes in temperature, so that they can be distinguished from the natural dentin.
