  • Patent number: 12076203
    Abstract: A method of making an absorbent insert for absorbing fluid in a root canal. Forming a body in a pre-compressed state prior to use, having a matrix of absorbent material. The matrix of absorbent material swells upon absorbing fluid after the body in the pre-compressed state has been inserted into the root canal. In the forming process, a sheet of absorbent material is compressed to form a compressed sheet, which is cut and shaped to form an insert. Cutting and shaping is by using complementary split mold halves which together define a cavity corresponding to the body of the insert and stamping the compressed sheet with the split mold halves to form the body of the insert.

  • Patent number: 12053920
    Abstract: An apparatus dispenses a raw material in liquid form into a manufacturing zone. The raw material is, by computer-controlled, point-by-point targeted light irradiation, heated and solidified by the region of incidence of a light beam relative to the manufacturing zone being altered in a continuous and/or in a step-by-step manner. The light beam is emitted from the light beam source, or from an optical unit influencing the light of the light beam source, with a substantially ring-shaped light intensity profile. The ring-shaped light intensity profile is formed by a ring-shaped region in which the light intensity initially increases in the direction toward the center of the ring from the outer diameter and then drops off again toward the inner diameter of the ring, with the light intensity being equal to zero in the interior region of the ring.
