Abstract: The present invention relates to a biopsy device (1) for obtaining a tissue sample. The biopsy device comprises an elongated tube shaped drill (2), extending along a longitudinal axis A, and comprising a cutting edge arrangement (3) at a distal end (4) of said drill (2). The drill (2) further comprises at least one flute (5) extending helically, along said longitudinal axis A, at an outer surface (6) of said drill (2), wherein said flute (5) extends from said distal end (4) and along a substantial part (7) of said outer surface (6) of said drill (2). The drill (2) is provided with an opening (10) at its distal end (4), wherein said opening (10) being in communication with a cavity (16) adapted to receive said tissue sample.

Abstract: A two-step system for chemically bonded ceramic (CBC) materials, and especially a dental filling material or an implant material. The system includes an initial working part-system to provide for improved early-age properties and a second main system to provide for improved end-product properties including bioactivity. The systems interact chemically. The invention also relates to the powdered materials and the hydration liquid, respectively, as well as the formed ceramic material.

Abstract: A system for a chemically bonded ceramic material (CBC), comprising a composite biomaterial for preferably dental and/or orthopaedic applications. The CBC-system includes a binding (chemical cement) and inert phases with specified geometry providing the biomaterial defect tolerance through an improved fracture toughness. The invention also relates to the powdered materials and the hydration liquid, respectively, as well as the formed ceramic material.
