Abstract: An osteosynthesis body consisting of a zirconium dioxide ceramic in the form of a screw or a shaped body for osteosynthesis such as a panel or a strip in a planar or three-dimensionally curved form which is provided in at least some sections with holes through which screws can be passed. This is preferably produced from TZP powder by means of HIP and a subsequent post-processing step in order to achieve the highest possible mechanical resilience from the finest possible powders, with an average specific surface area of, for example, 30 to 50 m2/g.

Abstract: A cutting knife and a method for production are provided, the knife being suitable for severing tough, elastic material, in particular cement beads of window panes cemented in motor vehicles. The knife comprises a securement portion having a securement receptacle for securing the cutting knife to an oscillatory drive of a cutting tool, and a cutting portion with at least one cutting edge. The cutting knife comprises a plurality of flat bonded layers, which are preferably bonded together by forging. Additionally or alternatively, an outer wear resistant layer is applied, preferably by thermal spraying. The cutting knife has an improved elasticity and increased bending strength in combination with improved cutting properties.
