Patent number: 7377943Abstract: The invention relates to a metallic implant, which has vitreous-crystalline bioactive material on the surface thereof. According to the invention, a metallic implant base body arranged on the surface of the particles has a bioactive, vitreous-crystalline material consisting of 15-45 wt. % CaO, 40-45 wt. % P2O5, 10-40 wt. % ZrO2 and 0.7-3.5 wt. % fluoride, having apatite and calcium zirconium phosphate as main crystalline and a glass phase as an auxiliary component. Said vitreous crystalline material contains at least 35 wt. % main crystal phases and at least 5-15 wt. % auxiliary compounds. All of the percentage data is expressed in relation to the total weight of the vitreous crystalline material and the particle size of the vitreous crystalline material is between 60-350 ?m.Type: GrantFiled: June 14, 2002Date of Patent: May 27, 2008Assignees: Humboldt-Universitaet Berlin, Charite Universitaetsklinikum, BAM Bundesanstalt fuer Materialforschung und - pruefungInventors: Wolf-Dieter Müller, Georg Berger

Patent number: 7223808Abstract: The invention relates to a method for the production of an adhesive and an adhesive kit for joining similar or different metal surfaces or ceramics, especially in the field of biomedicine. The objective of the invention is to avoid polymerization-linked by-products and disadvantageous effects, in addition to enabling a temporary biocompatible bond between metal and metal or metal and ceramics. The inventive method consist in using a monomer-free polymethylmethacrylate which is mixed with a suitable, non-toxic solvent and a bioactive vitreous-crystalline material with a particle size ranging from 0.05–20?, consisting of 15–45 wt. % CaO, 40–45 wt. % P2O5, 10–40 wt. % ZrO2 and 0.7–3.5 wt. % fluoride, having apatite and calcium zircon phosphate as main crystal phases and a glass phase as an auxiliary component until a flowable mixture is obtained. The invention also relates to an adhesive kit consisting of said components.Type: GrantFiled: June 14, 2002Date of Patent: May 29, 2007Assignees: Humboldt Universitaet Berlin Carite Universitaetsklinikum (CCM), Bam Bundesanstalt Fuer Materialforschung und -Pruefung, Vita Zahnfabrik H.

Patent number: 7086116Abstract: A dental cleaning implement such as a toothbrush, having longitudinally disposed first and second parts flexibly joined together. Between the first and second parts is a rotatable member such that when the implement bends the first parts adjacent to the member bear upon the member. The rotatable member has circumferentially disposed relatively softer and harder regions, so that as the member is rotated the parts can be caused to bear compressibly upon selected softer or harder regions.Type: GrantFiled: November 30, 2000Date of Patent: August 8, 2006Assignee: GlaxoSmithKline Consumer Healthcare GmbH & Co.

Patent number: 6919086Abstract: The invention relates to modified recombinant allergen mutants which can be obtained from recombinant allergens which are derived from allergens which can be obtained by extraction from natural raw materials such as pollen of the species Phleum pratense. While these modified recombinant allergens stimulate lymphocytes from patients who are allergic to pollent to proliferate and synthesize cytokines, they exhibit a markedly diminished ability to bind to the IgE antibodies which are present in the serum of the T lymphocyte donors and to grass pollen allergen-specific IgEs and can therefore be used for a specific, made-to-release allergy therapy.Type: GrantFiled: March 16, 1998Date of Patent: July 19, 2005Assignee: Merck Patent Gesellschaft mitInventors: Helga Kahlert, Hans-Thomas Stüwe, Helmut Fiebig, Oliver Cromwell, Wolf-Meinhard Becker, Albrecht Bufe, Gabriele Schramm, Lothar Jäger, Wolf-Dieter Müller
