    Abstract: The invention relates to a preform made of a cross-linked composite material to be machined in order to form crowns or bridges, especially by means of CAD/CAM, comprising an infrastructure formed by laying fibre-based fabrics one on top of the other, the fabrics being impregnated with a resin and being substantially spread over the thickness of said infrastructure, characterised in that it also contains a resin-based suprastructure, said suprastructure being fibre-free and secured to the infrastructure over the entire upper and lower surface thereof.

    Abstract: The present invention relates to dentistry, and particularly, to a rotary endodontic finishing file used for root canal treatment. The endodontic finishing file comprises a shank for inserting in an endodontic motor handpiece, and a core of twisted metal braids secured in the shank, the said core being provided with an outer braid made of wire wound over the core. The length of the braid is less than the length of the core. At the braid-free end of the core, a brush of the core braids is formed. The winding of the wire of the outer braid is made in four layers, the winding of the first and third layers is made in the direction from the shank to the brush without a gap between the adjacent coils in each layer, the winding of the second and fourth layers is made in the opposite direction, providing the possibility of securing both ends of the braid wire in the shank. The winding pitch in the second and fourth layers is 8 to 10 times greater than the winding pitch in the first and third layers of the braid, the winding length of the third and fourth layers in the direction from the shank to the brush is less than the winding length of the first and second layers. The core is made of three twisted elastic tungsten wires, the open ends of which, located in the braid-free portion of the core, are of a cylindrical helix shape and curved in the form of a conical helix with an increasing pitch of turns for each strand of the core, whereby the curved ends of the brush wires are inserted into the canal separately and sequentially one after another with the motor turned off, each inserted wire being pressed against the walls of the canal during the insertion of the file. The proposed technical solution allows to provide high-quality and safe treatment, reduce the risk of injury during treatment, and also increase the service life of the endodontic file.

    Abstract: An orthodontic separator including a substrate including at least one resilient material configured to produce and maintain an outward force for a predetermined time period between adjacent teeth, wherein the substrate includes a plurality of layers including polymer fibers having a fluoride compound incorporated therein or that coats a surface thereof. The plurality of layers is arranged concentrically and configured such that the plurality of layers of the substrate successively dissolve or disintegrate within the predetermined time period when disposed between those adjacent teeth, whereby the separator dissolves or disintegrates.
