ABSTRACT:
An orthodontic bracket comprises a bracket base, an arch wire slot configured to receive an arch wire, a ligation cover, an elongate film hinge that interconnects the bracket base and ligation cover, and a cam structure. The ligation cover is selectively rotatable about the film hinge relative to the bracket base between an open, non-ligating position and closed, ligating position relative to the arch wire slot. The cam structure includes a curved surface proximal to the elongate film hinge that assists in distributing forces throughout the entire length of the film hinge as the cover is rotated relative to the bracket base. The cam structure also includes a camming surface that biases the ligation cover toward the open, non-ligating position. The ligation cover covers at least a portion of the slot when in the closed, ligating position.
