  • Patent number: 8834751
    Abstract: A system and method for sintering dental restorations. The system can include a monolithic sintering support comprising a surface, and at least one dental restoration positioned in direct contact with the surface of the monolithic sintering support. The method can include providing a monolithic sintering support comprising a surface, positioning a dental restoration in direct contact with the surface, and sintering the dental restoration while the dental restoration is in direct contact with the surface of the monolithic sintering support to form a sintered dental restoration.

  • Patent number: 8119058
    Abstract: The present invention relates to a device and process for dimensionally stable sintering of ceramic pre-shaped dental articles, the device comprising a suspension system having a base structure with at least one suspension point at a height suitable for suspending an article to be sintered; and a suspension element moveably connected to said suspension point for supporting said article to be sintered, wherein said suspension element itself forms a swing on which said article to be sintered is arrangeable.
