Problems solved by technology

In the time between ligature damage and visit, orthodontic treatment may not be as efficient or as per the orthodontist's treatment plan
This in turn can increase treatment time and the time the patient has to wear braces

Embodiment Construction

[0025] Damaged ligatures are common in orthodontic treatment. The current solution to this problem is to replace the damaged ligature with a new one. The cost and time to do this is minimal, so the physician is just a practice, with the exception that some ligatures will break and the physician will have to replace them. The term "tie" is used herein with reference to elastic ties. These include, but are not limited to, O-ring type ligatures such as molded "O" rings and chain rubber bands supplied by Ormco Corporation, Orange California. Without being bound by theory, ligature failure, while generally considered to be an inherent property of elastic materials, also involves the orthodontic brackets in which the ligatures are placed. In this regard, physicians may have difficulty stretching the ligatures around the orthodontic brackets and archwires without tearing the ligatures. The further the ligature is stretched to install, the more it is stretched and the greater the r...

Abstract

An orthodontic bracket for coupling an archwire having a ligature to a tooth includes a bracket body configured to be mounted to the tooth, the bracket body including an archwire slot opened to one side of the bracket body and adapted to receive the archwire therein. At least two tie wings extend from the bracket body, the at least two tie wings each having a tip region and an under tie wing region, and the under tie wing region is configured to receive the ligature. The under tie wing regions each include a curvature in a plane parallel to a longitudinal axis of the archwire slot and extending in the same direction that the archwire slot opens at a location adjacent an outer end of the under tie wing region.

Description

technical field [0001] The present invention relates generally to orthodontic brackets, and more particularly to orthodontic brackets with tie wings. Background technique [0002] Orthodontic brackets represent a major component of any orthodontic treatment aimed at improving the patient's occlusion. In conventional orthodontic treatment, a physician or assistant secures the brackets to the patient's teeth and then engages an archwire into the seam of each bracket. The archwire applies an orthodontic force that forces the teeth to move into the correct orthodontic position. Traditional ligatures, such as small elastic O-rings or elastic chain rubber bands, can be used to retain the archwire within each bracket slot by means of ties. [0003] Self-ligating orthodontic brackets have been developed that rely on moveable members, such as latches or slides, to retain the archwire within the bracket slot, eliminating the need for ligatures. However, many self-ligating orthodont...
