Patent Application
20240299139
The present invention relates to orthodontic appliances and, more specifically, to an orthodontic appliance employing an archwire protecting tube.
Conventional braces typically include an archwire coupled between two anchoring brackets and placed across the patient's teeth. The arch wire is typically held in place by a plurality of intermediate brackets that are affixed to the teeth between the anchoring brackets. The anchoring brackets are typically affixed to the rear-most molars of the patient with an adhesive. In some cases, the anchoring brackets are soldered to metal bands that are fitted around the patient's rear-most molars.
Pediatric patients often have gaps between teeth while waiting for adult teeth to grow into the locations of removed baby teeth. Chewing food can result in substantial pressures on the archwire in these gaps. Frequently, this pressure can result in the breaking of the archwire, which can result in damage to the tissues in the area of the broken archwire. Also, archwire breakage is one of the most common reasons for emergency visits to the orthodontist.
Therefore, there is a need for a system that prevents archwire breakage.
The disadvantages of the prior art are overcome by the present invention which, in one aspect, is an orthodontic system for use with a patient having an arch that includes a plurality of teeth. The orthodontic system includes an anchoring bracket; a first affixing mechanism, a tube and an archwire. The first affixing mechanism is configured to affix the anchoring bracket to a selected first one of the teeth. The tube is affixed to the anchoring bracket and is configured to extend along a portion of the arch. The archwire is secured to the anchoring bracket and extends from the tube.
In another aspect, the invention is an orthodontic appliance for use with a patient having an arch that includes a plurality of teeth. The orthodontic appliance includes an anchoring bracket that defines two parallel passages and that includes a door that selectively covers the two parallel grooves. A first affixing mechanism is configured to affix the anchoring bracket to a selected first one of the teeth. A tube is affixed to the anchoring bracket and is configured to extend along a portion of the arch. The tube has a proximal end and includes: two parallel wires that extend from proximal end of the tube, each having a first end, wherein each of the parallel wires is configured to fit into a different one of the parallel grooves and a stop that couples the first ends of the two parallel wires and that is placed outside of the anchoring bracket so that when the door is in a closed position, the two parallel wires hold the tube in a fixe d relation to the anchoring bracket. An archwire is secured to the anchoring bracket and extends from the tube.
In yet another aspect, the invention is a method of preventing damage to a portion of an archwire in an orthodontic braces set for moving a plurality of teeth, in which an anchoring bracket is affixed to a selected first one of the teeth. A tube is secured to the anchoring bracket so that the tube extends around the portion of the archwire.
These and other aspects of the invention will become apparent from the following description of the preferred embodiments taken in conjunction with the following drawings. As would be obvious to one skilled in the art, many variations and modifications of the invention may be effected without departing from the spirit and scope of the novel concepts of the disclosure.
A preferred embodiment of the invention is now described in detail. Referring to the drawings, like numbers indicate like parts throughout the views. Unless otherwise specifically indicated in the disclosure that follows, the drawings are not necessarily drawn to scale. The present disclosure should in no way be limited to the exemplary implementations and techniques illustrated in the drawings and described below. As used in the description herein and throughout the claims, the following terms take the meanings explicitly associated herein, unless the context clearly dictates otherwise: the meaning of “a,” “an,” and “the” includes plural reference, the meaning of “in” includes “in” and “on.”

In the present invention, the tube itself is removable so that, as treatment progresses and when the tube is no longer required, it can be removed and the archwire by itself can be secured to the anchor bracket. As a result, the present invention is multifunctional and gives the orthodontist the ability to use it with brackets and wires, or with the tubes according to the patient's treatment progress. In a course of treatment, the orthodontist can start with conventional braces and then add the tubes later without having to remake and re-glue the fittings. The orthodontist can employ separate attachments that fit in the brackets on an as-needed basis as treatment progresses. The brackets, tubes and eyelets can be assembled extra-orally and stabilized with rope wax while awaiting oral placement. Molar tubes can be used as regular archwire slots. Occlusal slots can act as base archwires. Gingival slots can be used to have an auxiliary full sized wire to be steel tied to the anterior to create an intrusive force. Archwires can be first employed to de-rotate molars and then they can be replaced with tubes.
Although specific advantages have been enumerated above, various embodiments may include some, none, or all of the enumerated advantages. Other technical advantages may become readily apparent to one of ordinary skill in the art after review of the following figures and description. It is understood that, although exemplary embodiments are illustrated in the figures and described below, the principles of the present disclosure may be implemented using any number of techniques, whether currently known or not. Modifications, additions, or omissions may be made to the systems, apparatuses, and methods described herein without departing from the scope of the invention. The components of the systems and apparatuses may be integrated or separated. The operations of the systems and apparatuses disclosed herein may be performed by more, fewer, or other components and the methods described may include more, fewer, or other steps. Additionally, steps may be performed in any suitable order. As used in this document, “each” refers to each member of a set or each member of a subset of a set. It is intended that the claims and claim elements recited below do not invoke 35 U.S.C. § 112(f) unless the words “means for” or “step for” are explicitly used in the particular claim. The above-described embodiments, while including the preferred embodiment and the best mode of the invention known to the inventor at the time of filing, are given as illustrative examples only. It will be readily appreciated that many deviations may be made from the specific embodiments disclosed in this specification without departing from the spirit and scope of the invention. Accordingly, the scope of the invention is to be determined by the claims below rather than being limited to the specifically described embodiments above.
