Problems solved by technology

[0035] The above-mentioned lost torque problem caused by the vertical gap between the archwire and the traditional square archwire slot has been exacerbated in recent years by the fact that rectangular archwires of substantially smaller dimensions have been adopted in straight archwire technology.

Embodiment Construction

[0079] The improved square wire bracket of the present invention solves the problem of capturing lost torque during the final stages of orthodontic treatment due to the need for vertical clearance between the archwire slot and the wire itself to Created in square wire brackets to allow insertion of the arch wire. Heretofore, the present invention avoids the capture of lost torque typically employed by archwire bending techniques by locating the conduit and lumen in the bracket at an angle relative to the archwire slot, which accepts a thin, flexible archwire , to apply force to the bracket, so that the obliquely opposite end of the arch wire groove fits with the upper and lower surfaces of the rectangular arch wire, so as to obtain the predetermined torque value of the bracket.

[0080] The present invention includes the use of a tube and lumen to receive a movable thin flexible wire, while in the case of a rectangular archwire, said rectangular archwire should remain in the r...

Abstract

An edgewise orthodontic bracket 10 for use in an edgewise or straight-wire technique having a standard horizontally opening rectangular archwire slot 18 and a mesiodistally extending tunnel or lumen 20 separate from and vertically angled to the archwire slot for receiving a relatively small flexible wire 34 during the use of an undersize rectangular archwire 30 in the archwire slot to apply a force to the bracket for capturing lost torque.

Description

technical field [0001] The present invention generally relates to an edgewise orthodontic bracket having a rectangular archwire slot for receiving a rectangular archwire and a conduit for receiving a thin flexible archwire for feeding Brackets apply force and eliminate gaps or gaps between archwires and archwire slots with slightly smaller vertical dimensions, particularly with respect to a new and improved square wire orthodontic bracket that captures lost torque (lost torque) and achieve more accurate results in final tooth positioning. Background technique [0002] When Dr. Edward Angle first proposed the bracket and arch wire of the square wire arch mechanism in 1925, the arch wire was made of gold, and the bracket was composed of a solid metal block. Dr. Angle originally claimed that his square wire arches were "...exactly .022 inches thick and .028 inches wide to fit exceptionally precisely into the archwire slots of the brackets" (Angle, E.H., The latest and best in ...
