Abstract: A dental screw for osseointegration of a bone surface includes a base, a healing cap, and a handle. The base includes a penetrating body configured to penetrate into a bone. An area of the penetrating body at a proximal side of the base is smaller than an area of the penetrating body at a distal side of the base.

Abstract: A device for coating a wire with polymer fibers and method thereof are provided. The device includes a wire holder unit fixing both ends of a wire, a fiber forming unit including a first fiber forming module and a second fiber forming module that receive a polymer solution, face each other, and form fibers while approaching each other and retreating from each other, and a control unit adjusting a tension of the wire by controlling the wire holder unit and crossing the wire and the fibers by controlling the fiber forming unit. The fiber forming unit rotates the wire along an axis which extends in a longitudinal direction of the wire. The fibers are attached and coated on the wire when the wire and the fibers cross each other. The wire coating method can improve an adsorption state of coated fibers by including a post-processing step.

Abstract: A wire coating device and method are provided. The wire coating device includes a wire holder unit fixing both ends of a wire, a fiber forming unit including a first fiber forming module and a second fiber forming module that are applied with a polymer solution, face each other, and form fibers while approaching each other and retreating from each other, and a control unit adjusting a tension of the wire by controlling the wire holder unit and crossing the wire and the fibers by controlling the fiber forming unit. The fiber forming unit spins the wire using a longitudinal direction of the wire as an axis. The fibers are attached and coated on the wire when the wire and the fibers cross each other. The wire coating method can improve an adsorption state of coated fibers by including a post-processing step.

Abstract: Dental braces according to one embodiment of the present invention comprise: wires for straightening teeth; a coating agent coated on the outer surfaces of the wires; and fixing parts for fixing the wires, coated with the coating agent, on the surfaces of the teeth and fixing the wires such that the wires can move along the longitudinal direction of the wire. A wire positioning unit applied to the surface of the tooth comprising a body and a slot configured to receive the wire.

Abstract: Dental braces according to one embodiment of the present invention comprise: wires for straightening teeth; a coating agent coated on the outer surfaces of the wires; and fixing parts for fixing the wires, coated with the coating agent, on the surfaces of the teeth and fixing the wires such that the wires can move along the longitudinal direction of the wire, wherein the coating agent coated on the wires is removed from the wires after the coating agent is covered with the fixing part, such that a clearance gap can be formed between the fixing part and the wire, thereby enabling accurate and smooth teeth-straightening.

Abstract: An orthodontic appliance comprising an upper splint defining a set of tooth sockets for secure but removable retention to the upper set of teeth, a lower splint defining a set of tooth sockets for secure but removable retention to the lower set of teeth, and a pair of elastic linkages which connect the upper and lower splints so as to force the maxilla forward. A traction bow with two ends adapted for releasable connection to the lower splint is provided with a sub bar fixed to its frontal center, and a hook is provided on each side of the upper splint. An elastic linkage is removably connected between each of the hooks and a clasp on an end of the sub bar. The sub bar is substantially shorter in length from end to end than the main bowed bar of the traction bow.
