  • Patent number: 7899221
    Abstract: Surface mapping and/or generation device is provided, with a device for mapping 3D data of at least one denture base object such as a tooth stump or an implantation abutment, and an environment thereof, as well as with a device for the data-based generation and production of a denture part incorporating the 3D data of the denture base object. Additionally provided are a device for determining and/or defining a placement direction of the denture part that is to be slipped onto the denture base object, and a device for determining and producing a primary part that is to be slipped onto the denture base object before the denture part and that yields a desired placement direction for the denture part which is different from the placement direction that exists for slipping the primary part onto the denture base object. The device for data-based generation and production of a denture part is designed to generate and produce the latter by incorporating the 3D data of the primary part.

  • Patent number: 7897180
    Abstract: The present invention relates to the use of a preparation of an active enamel matrix substance, such as an amelogenin, for the manufacture of a pharmaceutical composition for modulating an immune response. The composition can be used in preventing and/or treating a condition or disease in a mammal that is characterised by said mammal presenting an imbalance in its native immune response to an internal and/or external stimuli, i.e. wherein at least a part of said mammal's immune system is stimulated non-discriminatingly, reacts hypersensitively to said immunogen, or fails to react to said stimuli. Said condition can typically either be systemic or local, such as a systemic and/or post-traumatic whole-body inflammation or an autoimmune disease.
