  • Patent number: 9669111
    Abstract: The document proposes a diagnostic chewing gum for identifying the presence of inflammatory tissues in the mouth, in particular in or adjacent to the mandible, the maxilla, an implant or the teeth of a user, comprising a base material or particles (3) embedded and/or attached to the base material; an element (1, 5-7), like e.g. a releasable flavor molecule, attached to the base material and/or the particles, for the generation of a change in the chewing gum directly detectable by the user; wherein the element (1, 5-7) generates the change upon direct or indirect contact with a marker (4), e.g. a proteolytic enzyme, which is released by inflammatory tissue in response to bacterial mediators.

  • Patent number: 8642064
    Abstract: A method of producing a self-hardening, bioabsorbable composite material, the material produced and its areas of application are described. The method is based on the principal method steps (I) immobilisation of a polymerisation initiator in a microporous pore system of a first partial amount of a bioabsorbable calcium phosphate used in producing the self-hardening, bioabsorbable composite material, (II) immobilisation of a polymerisation activator in the microporous pore system of a second partial amount of the bioabsorbable calcium phosphate used in producing the self-hardening, bioabsorbable composite material and (III) homogeneous mixing of the components according to (I) and (II) with a liquid or paste-form, multi-functional monomer capable of forming a biocompatible, bioabsorbable polymer network or a corresponding monomer mixture and, optionally, with further constituents which modify the properties of the monomer or monomer mixture.
