This application is a reissue application of U.S. Pat. No. 8,162,660 (application Ser. No. 12/592,078, filed Nov. 20, 2009), which is hereby incorporated by reference herein in its entirety for all purposes.
The present invention is directed to a locking orthodontic bracket that contains a mechanism that rotationally locks an orthodontic archwire within the bracket archwire slot.
Orthodontic brackets attached to teeth transmit forces, such as produced by an archwire, to move the teeth. Brackets usually contain an archwire slot for reception of the archwire. Orthodontic brackets today are typically bonded to a tooth or welded to an orthodontic band that is cemented to the tooth.
Brackets commonly use tie wings that project upwardly and downwardly in pairs at the top and bottom of the installed bracket, respectively. These wings permit the archwire to be held within the archwire slot of the bracket by means of a twisted wire (ligature) or an elastomeric o-ring. Currently there are varieties of brackets that are self-ligating. These self-ligating brackets have taken several forms.
U.S. Pat. No. 5,094,614 to Wildman, issued Mar. 10, 1992, discloses a sliding closure that engages the front of the archwire. The closure is recessed from the front or anterior surfaces of the disclosed bracket. These sliding closures are also found in U.S. Pat. No. 2,549,528 to Russell, U.S. Pat. No. 2,671,964 to Russell et al. and in U.S. Pat. No. 3,131,474 to Johnson. Sliding closures require the archwire also to be recessed within the archwire slot before the closure can be moved over the archwire making it very difficult for the user to visually confirm that the archwire is properly seated within the archwire slot. A conventional bracket has a visual front surface adjacent to the archwire slot making it easy to see if the archwire is seated in the archwire slot. This is not true in the recessed sliding closures. The actual archwire slot surface is beneath the sliding closure. Damon solved this problem in U.S. Pat. Nos. 5,275,557 (Jan. 4, 1994), 5,429,500 (Jul. 4, 1995) and 5,466,151 (Nov. 14, 1995).
An achievement of these patents is a ligating slide within a bracket that maintains the normal features of protruding tie wings or lugs and a closure in the form of a ligating slide that can complete a continuous tube surrounding the archwire when the closure is in a closed position. This can be achieved in a Siamese or twin bracket configuration without covering or interfering with projecting extensions on the bracket.
Pletcher, U.S. Pat. No. 5,322,435, discloses a locking slide member that is flat and guided by upright slots formed along both sides of the bracket and spanning the archwire slot thereby obscuring visual access to the critical corners of the archwire slots at the side edges of the bracket. Without this visual access being clear, one installing an archwire within a bracket cannot be certain as to proper seating of an archwire within the archwire slot before the slide cover is moved to a closed position. No tie wings or lugs are included in the illustrated bracket forms.
There is a modern esthetic requirement that the brackets be small. A drawback of many self-ligating brackets the locking covers increase the size of the bracket.
Damon, U.S. Pat. No. 6,071,118, discloses a sliding cover which gives visual access to the archwire slot, but have achieved the enclosure of the sliding cover by thickening the bracket in the gingival area
A sliding spring cover, a hinged locking cover, a rotary sliding cover, a ball type rotatable cover etc. have been disclosed in different U.S. Patents. “Activa” produced by A Company, “Speed” and “Edgelock” produced by Ormco Corporation, and others are typical examples of ligature-less brackets that are commercially available.
Of all these different locking means a sliding closure has been considered desirable because it can be easily manipulated and it reduces the time required for opening and closing of the arch wire slot during periodic adjustments of the arch wire and provides more precise control of the archwire. There are other means that are more complex and difficult and expensive to manufacture. Springs used as locking means are not strong enough to hold the arch wire into the slot.
The present invention is directed to a locking orthodontic bracket. The locking orthodontic bracket is comprised of an orthodontic bracket that contains a rotating clip device for locking an orthodontic arch wire within the arch wire slot of the orthodontic bracket. The orthodontic bracket is comprised of a body containing a slot to receive an arch wire, wings for tying ligature wires, a base that is attachable to an orthodontic band or directly to a tooth surface and a central recess on the front surface of the body that extends inwardly towards the base of the bracket. The invention is a rotating clip for locking the orthodontic arch wire within the arch wire slot. Rotation of the clip in one direction leaves the archwire slot open for the insertion or removal of an archwire and rotation in the opposite direction locks the archwire in the archwire slot.
The rotating clip is comprised of a hollow cylindrical body with wings extending from the body. The cylindrical body has a circular base and two opposing vertical walls separated by opposing open sides. The opposing open sides allow for the passage of an archwire through the archwire slot and reduce friction during rotation of the rotating clip. The circular body is fitted and mechanically retained within the recess within the orthodontic bracket. The bracket recess is shaped and sized to receive the hollow circular body. The circular body and bracket recess may contain retentive devises such as circular grooves with matching ridges that also allow rotation of the rotating clip within the bracket recess. The wings extend laterally from the vertical cylindrical body over the surface of the orthodontic bracket. The tubular body is rotatable within the recess of the orthodontic bracket. The rotation moves the wings in a clockwise or counterclockwise motion. The bracket clip insertion hole can be slightly skewed from a perfect circle to allow friction grip when the clip is fully open or fully closed.
In a preferred embodiment, the tips of the wings enclose an orthodontic arch wire within the arch wire slot of the orthodontic bracket when the rotating clip is rotated counterclockwise. A clockwise rotation of the rotating clip opens the arch wire slot for placement or removal of the orthodontic arch wire. The strength transmitted to the wing tip is partially derived from the circular shape of the attached cylindrical body and the intimate fitting of the cylindrical body within the circular recess. The resulting strength is increased allowing the wings to be thinner which is advantageous for patient comfort. The underside of the wing, in one embodiment, has a bump that actively holds the archwire in the slot, as opposed to passively holding the archwire when the underside of the wing is flat. In another embodiment the rotating clip has two sets of wings wherein one pair actively engage the archwire when the rotating clip is rotated in one direction and passively holds the archwire when the rotating clip is rotated in the opposite direction. In another preferred embodiment, the locking clip wing is shaped to enclose most of the arch wire in the archwire slot. In another preferred embodiment, the underside of the locking clip wing contains a bevel to push the arch wire into the arch wire slot. In a further embodiment, the underside of the wing contains bumps for active clip design.
The bracket wall that retains the rotating clip remains open to self cleanse, reducing calculus build up and stuck moving parts. Tooth brush bristles can access the walls of bracket body. The bracket body design remains the same for both active and passive and active passive designs. The design allows the clinician to go from passive to active to conventional and back at any point in treatment. Height gauges may be used conventionally. The rotating clip does not interfere with anatomical structures, such as gums and other teeth, when in the open position. The rotating clip orthodontic bracket may be comprised of metal, plastic or ceramic or combinations thereof. Equivalent materials may be used. MIM technology can be used for the bracket body wherein retention for the clip is built within and there is a potential to use a breakaway design in MIM for one piece bracket body assembly. The door design will allow only the mesial or distal aspect of wing to be engaged on severely rotated teeth as the wing door can close around one wing while leaving the wire exiting the center of the bracket. The wire can be engaged from both the gingival and the occlusal in door design
There is an ability to cut out the facial aspect of the bracket leaves latitude to maintain slot integrity while increasing bulk of metal in body and arms , but allowing slot cover part of clip to be thin for springiness (passive/active). It can be designed with reciprocal open and closed doors. There are many designs in the clip. The designs may be passive or active with the same bracket body which can be a stand-alone twin without the rotating clip. The wings may be altered for the use of non-binding power chains for closing spaces or rotating teeth. Horizontal slots can be added lateral surfaces of the wings. Vertical and horizontal channels may be placed for accessories such as hooks and rotators.
The invention is comprised of a self-ligating orthodontic bracket assembly 1.
When orthodontic brackets are placed upon teeth they are ideally positioned with the bracket slot a predetermined distance from the incisal edge or occlusal surface of the tooth. In addition, the horizontal direction of the orthodontic bracket is placed at a right angle to the long axis of the tooth. An index pin 45,
The invention may include integral hooks for rubber band wear by the patient. In the alternative, channels may be placed in the invention to receive removable hooks for rubber band and other attachments. The rotating clip orthodontic bracket may be comprised of a variety of materials including metal, plastic and ceramic and decorative forms consisting of a variety of colors, glow-in-the-dark and LED lights which may be activated by the patient tapping their teeth together.
The invention, as described, is not limited to the specific embodiments described as these are preferred embodiments. The invention is claimed in any of its modifications within the proper scope of its claims.
