ABSTRACT:
An archwire locking device for an orthodontic bracket system is provided. The system includes a series of conventional edgewise brackets which engage the teeth of a patient by means of an adhesive which bonds the bracket to the tooth. Each bracket includes a laterally extending slot for selectively receiving an orthodontic archwire. The archwire locking device of the invention is used for maintaining the archwire within the laterally extending archwire slot of the bracket. The locking device is selectively moveable between a first locked position and a second unlocked position.
