  • Patent number: 9192453
    Abstract: This invention is a dynamic orthodontic bracket system which allows brackets to be adjusted for particular angulations required for each individual tooth of a patient, while the frames are continuously attached to tooth surface. The orthodontist manually adjusts the relationship of a bracket and a frame during treatment eliminating the necessity of a full repositioning of all components. The bracket is positioned such that it can move in various directions to achieve a proper angulation for tooth repositioning. The base of the bracket and the interior surface of the frame can be textured to provide friction and secure the components once positioned for proper tooth movement. The exterior of the frame can also be textured to provide more secure attachment to the surface of the tooth. This system will lead to lower treatment cost and quicker adjustments of the orthodontic bracket system.

    Abstract: An orthodontic brace system includes brackets having a diamond-shaped tie-wing configuration that defines two parallel, horizontal slots, each of which is adapted to receive an archwire. Each slot is angled with respect to the base of the bracket to produce a specific, maximum torque value, and generally, the maximum torque value of the gingival slot is less than the maximum torque value of the incisal slot. The brackets provide multiple force vectors in different directions simultaneously, which decreases the amount of time required for a patient to wear braces, reduces the number of costly and time consuming visits to an orthodontist, and reduces time and effort required of an orthodontist for installation and adjustment of the braces on a per visit basis.

  • Patent number: 7597553
    Abstract: An orthodontic bracket enables orthodontic treatment to be performed without resetting of a bracket body and an arch wire relative to the tooth, even in an advanced stage of the treatment. The orthodontic bracket comprises a bonding plate having a bonding surface matching the curvature of the tooth, a base having a bottom surface united with the bonding plate and an upper surface serving as a sliding surface parallel to the longitudinal axis of the tooth and taking an approximately rectangular shape in plan with a convex curve formed in accordance with the long axis of the tooth. A bracket body is mounted on the sliding surface of the base so as to be slidable along the tooth axis. The base has, at opposing sides of the sliding surface, grooved parallel rails for slidably holding the bracket body therebetween. Each rail has, at its opposite ends, stoppers to prevent detachment of the bracket body. The sliding surface has a central longitudinally-extending visible median line.

  • Publication number: 20080293005
    Abstract: An adjustable orthodontic bracket including an body member for fixing orthodontic arch wire in a position such that a predetermined stress is generated and applied to the tooth to be treated; a bonding base member for bonding the bracket to a buccal or lingual surface of a tooth to be treated; and a bendable element, wherein the bendable element connects the body member to the bonding base member. The body member includes a slot for the arch wire, wherein the bendable element enables to adjust accurate angles of the slot. The bendable element can be rigid or flexible wherein in the flexible form, a holding device is further included. The present invention further provides tools to band and/or rotate the adjustable orthodontic bracket of the present invention.

  • Patent number: 7306458
    Abstract: This invention provides an adjustable orthodontic bracket. The adjustable orthodontic bracket includes an orthodontic arch wire slot/tube and fixing part, an adjustable part, and a tooth surface fixing part. The orthodontic arch wire slot and fixing part is used to fix one or several orthodontic arch wire(s). The adjustable part is fixed under the orthodontic arch wire slot/tube and fixing part and provides a structure allowing the orthodontic arch wire slot/tube and fixing part to be turned around and fixed, and thereby the orthodontic arch wire slot/tube and fixing part is able to generate a stress to teeth for orthodontic treatment through turning itself around to pull and drag the orthodontic arch wire(s). The tooth surface fixing part is used to fix the adjustable part on tooth surface.

  • Publication number: 20020028416
    Abstract: An orthodontic bracket defining a wire guide therethrough is described. The bracket includes first and second planar surfaces in the wire guide. The first planar surface is disposed at a predetermined angle from the second planar surface so that the first and second planar surfaces act as stops to limit tipping of the bracket when either planar surface abuts a wire disposed through the wire guide. In this manner the bracket incorporates stops to prevent the over-correction of a tooth during an orthodontic procedure.

  • Patent number: 5954502
    Abstract: An adjustable orthodontic bracket assembly includes a plurality of brackets. Each bracket is attachable to a front face of a tooth such that the bracket is positionable in series relation to one or more other of the brackets. Each bracket is continuously adjustable in at least three planes and, preferably, in six planes of motion without a need to replace any parts thereof. The adjustment of each bracket in one of the planes of motion can be accomplished without affecting the adjustment of the bracket in any of the other planes of motion. Specifically, each bracket is capable of adjustment in at least three and, preferably, all of vertical, lateral and mesio/distal translational planes of motion and tip, torque and circular rotational planes of motion. Also, the assembly includes an arch wire extending between and retained on the brackets.
