Abstract
The present invention is directed to a locking orthodontic bracket that contains a mechanism that rotationally locks an orthodontic archwire fully or partially within the bracket archwire slot. The orthodontic bracket has a body containing a slot to receive an orthodontic archwire, wings for tying ligature wires, a base that is attachable to an orthodontic band or directly to a tooth surface and a central recess in the front surface of the body that contains the rotating clip device. The rotating clip device is rotated to enclose an orthodontic archwire within the slot.
Claims34
A rotating clip orthodontic bracket comprising:
- an orthodontic bracket comprising a body, the body having a back, a front with a center, left and right sides, a top and a bottom, the body front contains an archwire slot extending horizontally left side to right side shaped to receive an orthodontic archwire with right and left ends, left and right tie wings at the top and bottom body for tie wires or elastomeric ties for securing an archwire within the archwire slot;
- a cylindrical recess with walls in the center of the body front of the orthodontic bracket wherein the cylindrical recess is open on the body front and extends towards the body back wherein the cylindrical recess ends with a circular floor;
- and
- a rotating clip within the cylindrical recess for securing orthodontic archwires comprised of a circular base, two attached opposing columns separated by open opposing sides which allow the passage of an archwire through the archwire slot, each column supporting a c-shaped extension with a free end and an underside facing the bracket front wherein the circular base is fitted to the wall adjacent to the circular floor, the opposing columns are fitted to the cylindrical recess walls and the c-shaped extensions extend on the bracket front in opposing directions, the clip is fitted in the cylindrical recess and when the clip is rotated in a clockwise rotation position the bracket slot is open allowing the insertion and removal of an archwire and when the clip is rotated in a counterclockwise position the c-shaped extensions retain the archwire within the archwire slot at the right and left ends of the archwire slot.
The rotating clip orthodontic bracket comprising:
- an orthodontic bracket comprising a body, the body having a back, a front with a center, left and right sides, a top and a bottom, the body front contains an archwire slot extending horizontally left side to right side shaped to receive an orthodontic archwire with right and left ends, left and right tie wings at the top and bottom body for tie wires or elastomeric ties for securing an archwire within the archwire slot;
- a cylindrical recess with walls in the center of the body front of the orthodontic bracket wherein the cylindrical recess is open on the bracket body front and extends towards the bracket body back wherein the cylindrical recess ends with a circular floor;
- and
- a rotating clip within the cylindrical recess for securing orthodontic archwires comprised of a circular base, two attached opposing columns separated by open opposing sides which allow the passage of an archwire through the archwire slot, the columns supporting first and second opposing sets of c-shaped extensions, the first set with a c-shaped extension adjacent to the top left tie wing, wherein the first opposing c-shaped extension end undersides each have a bump and the second opposing c-shaped extension end undersides are each flat, the circular base is fitted to the cylindrical recess wall adjacent to the circular floor, the opposing columns are fitted to the cylindrical recess walls and the c-shaped extensions extend on the bracket front in opposing directions, the clip is fitted in the cylindrical recess and when the rotating clip is in a center position the bracket slot is open allowing the insertion and removal of an archwire in the archwire slot, when the rotating clip is rotated in a counterclockwise position the bumps, on the underside of the c-shaped extensions, push on the archwire to retain the archwire actively within the archwire slot at the right and left ends of the archwire slot, when the rotating clip is rotated clockwise the flat undersurface of the c-shaped extensions push on the archwire holding hold the archwire passively in the archwire slot.
A method of orthodontic treatment with an archwire comprising:
- attaching an orthodontic bracket including a bracket body and a rotatable clip to a tooth, the bracket body defining an archwire slot;
- inserting an archwire into the archwire slot;
- rotating the rotatable clip to a first closed position in which the rotatable clip passively ligates the archwire;
- and
- rotating the rotatable clip to a second closed position in which the rotatable clip actively ligates the archwire,
- wherein rotating the rotatable clip includes rotating the rotatable clip about an axis of rotation that lies within the archwire slot.
A method of orthodontic treatment with an archwire comprising:
- attaching an orthodontic bracket including a bracket body and a rotatable clip to a tooth, the bracket body defining an archwire slot and the rotatable clip including a first extension and a second extension;
- inserting an archwire into the archwire slot when the rotatable clip is in an opened position in which the first extension and second extension are spaced apart by the archwire slot;
- rotating the rotatable clip to a first closed position in which the rotatable clip encloses the archwire in the archwire slot so as to passively ligate the archwire;
- and
- rotating the rotatable clip in the same direction to a second closed position in which the rotatable clip encloses the archwire in the archwire slot so as to actively ligate the archwire.
A method of orthodontic treatment with an archwire comprising:
- attaching an orthodontic bracket including a bracket body and a rotatable clip to a tooth, the bracket body defining an archwire slot and the rotatable clip including a first extension and a second extension that each extend laterally outward from a clip body;
- inserting an archwire into the archwire slot;
- rotating the rotatable clip about an axis of rotation that is generally perpendicular to the archwire slot to a first closed position in which the first extension and the second extension enclose the archwire in the archwire slot so as to passively ligate the archwire;
- and
- rotating the rotatable clip to a second closed position in which the first extension and the second extension enclose the archwire in the archwire slot so as to actively ligate the archwire.
A method of orthodontic treatment with an archwire comprising:
- attaching an orthodontic bracket including a bracket body and a rotatable clip to a tooth, the bracket body defining an archwire slot and the rotatable clip including a first extension and a second extension that each extend laterally outward from a clip body;
- inserting an archwire into the archwire slot;
- rotating the rotatable clip to a first closed position in which the first extension and the second extension enclose the archwire in the archwire slot so as to passively ligate the archwire;
- and
- rotating the rotatable clip to a second closed position in which the first extension and the second extension enclose the archwire in the archwire slot so as to actively ligate the archwire,
- wherein rotating the rotatable clip to the first closed position includes rotating the rotatable clip in one of the clockwise or counterclockwise directions and rotating the rotatable clip to the second closed position includes rotating the rotatable clip in the other of the clockwise or counterclockwise directions.
A method of orthodontic treatment with an archwire comprising:
- attaching an orthodontic bracket including a bracket body and a rotatable clip to a tooth, the bracket body defining an archwire slot and the rotatable clip including a first extension and a second extension that each extend laterally outward from a clip body;
- inserting an archwire into the archwire slot;
- rotating the rotatable clip to a closed position in which a bottom surface of each of the first extension and the second extension closes off the archwire slot.
