  • Press muffle
    Patent number: 9017054
    Abstract: The invention concerns a press muffle made of an embedding mass for the production of dental restoration parts, with the embedding mass comprising at least one weakly heat-conducting, in particular ceramic, basic powder, with up to 70%, in particular 2% to 40% of the entire embedding mass (12) consisting of an additive having a higher thermal conductivity than the basic powder.
    Type: Grant
    Filed: October 11, 2011
    Date of Patent: April 28, 2015
    Assignee: Ivoclar Vivadent AG
    Inventors: Harald Bürke, Rudolf Jussel, Heinrich Kappert, Gottfried Rohner, Thomas Stampfer
  • Muffle and method of using
    Patent number: 8257622
    Abstract: The invention proposes a muffle with a pressing channel and at least one mold cavity that is coupled to the pressing channel via at least one connection channel. In this case, in order to increase the pressing pressure and to improve the intermixing of the blank material, it is proposed to arrange at least two blanks (18) side by side in the pressing channel (12).
    Type: Grant
    Filed: November 5, 2008
    Date of Patent: September 4, 2012
    Assignee: Ivoclar Vivadent AG
    Inventors: Harald Gritsch, Max Wörishofer, Christoph Zobler, Thomas Stampfer, Hans-Peter Foser

  • Retort system
    Patent number: 7118085
    Abstract: A method for producing dental restoration components includes filling a retort cylinder of a retort system with a forming mass, the retort cylinder being at least partially encircled by a charging body, and hardening the forming mass. After the hardening of the forming mass, the retort cylinder and the charging body are removed from the forming mass, thereby leaving behind a retort. Thereafter, with the assistance of a press blank apparatus, a press blank having an outer contour substantially corresponding to the outer contour of the charging body is pressed into the retort.
