ABSTRACT:
An orthodontic bracket having an archwire slot includes a arc-shaped leaf spring capable of exerting a lateral force onto an archwire inserted into the archwire slot. The leaf spring is secured to a structure of said bracket at positions spaced along the slot. The bracket may have a slider plate to close the slot to avoid ligatures. In another embodiment the structure comprises an undercut holding the archwire in a position defined by the pressure exerted by the leaf spring. A bent slider may be interposed between said leaf spring and the archwire.
