Claim:
1. A self-ligating bracket system having variable resistance to sliding, the system comprising: a bracket body, including an archwire slot formed therein for receiving an archwire; at least a first tie wing attached to the body and having a clip receiving slot extending therein; a clip retainably receiveable within the receiving slot of the at least a first tie wing, such that at least a portion of the clip extends over at least a portion of the archwire when the archwire is received in the archwire slot, the retainably received clip being configured to retain the received archwire; and a deflection control component configured to cooperate with the clip to securely retain the clip, wherein the deflection control component has a first end and a parallel section which has an axis parallel to the archwire slot, wherein the first end and the parallel section together form a substantially 90° angle, and wherein the first end of the deflection control component is fixed to the bracket body via at least a first point, such that the deflection control component is pivotable about the first point, thereby varying a position of the parallel section relative to the archwire slot and the clip, and wherein a flexibility of the clip to resist deflection to the archwire varies with a pivoted position of the deflection control component.
