  • Publication number: 20140332394
    Abstract: An antibacterial coating that is composed of silver is disclosed, as well as medical tools and implants comprising such a coating, and a method and an apparatus for the production of such a coating. The medical tools or the dental or orthopaedic implant comprises a metal or metal alloy having a treated surface wherein the treated surface is at least partially converted to an oxide film by plasma electrolytic oxidation using a colloid-dispersed system and wherein the converted surface is partially covered by islands formed by colloid-dispersed silver-particles of the colloid-dispersed system. An Ag—TiO2 coating shows excellent properties in terms of antibacterial efficacy (even against multi-resistant strains), adhesion and biocompatibility. The life-time of an implant in a human body is increased. The antibacterial coating can be used in the field of traumatology, orthopaedic, osteosynthesis and/or endoprothesis, especially where high infection risk exists.

  • Publication number: 20140324188
    Abstract: The invention relates to implants that are implanted into living beings as temporary implants and that disintegrate in the body through biological adsorption over a period of time, in addition to a process for producing aforesaid implants. The implant according to the invention consists of magnesium or a magnesium master alloy. It is formed from fibers of magnesium or a magnesium master alloy that are connected to one another through sintering bridges that are locally spaced vis-à-vis each other and form an open-pored body. The fibers may be produced with the help of the melt extraction process and may subsequently be sintered with one another.

  • Publication number: 20140076015
    Abstract: An apparatus and method for bending or shaping orthodontic archwires or other medical devices into a complex, patient individual shape is described. The apparatus comprises of two moveable, compact, manipulators with, in total, at least three revolute joints defining three rotation axes and at least three prismatic joints defining at least three translation axes. Gripping tools are provided on the manipulators. The two manipulators are arranged to allow a relative movement in six degrees of freedom. A reduced complexity embodiment is also described having only one or two revolute joints.

  • Publication number: 20070249052
    Abstract: The present invention relates to a method for the generation of chondrons and of cartilaginous tissue. In particular, the present invention relates to the ability of Mg ions to stimulate the growth and regeneration of chondrons, particularly of pseudo-chondrons as an intermediate in the regeneration and growth of cartilaginous tissue. Especially, Unphysiologically high extracellular concentrations of Mg are able to regenerate hyaline cartilage, elastic cartilage and/or fibrocartilage via the intermediate form of chondrons.
