ABSTRACT:
A self-ligating orthodontic bracket includes a bracket base, an arch wire slot in the bracket base, and a ligation cover. The bracket base and the ligation cover comprise a polymer resin reinforced with c-glass fibers. The cover is hingedly connected to the bracket base and rotatable relative to the bracket base between an open, non-ligating position and a closed, ligating position. Reinforcing the polymer resin with c-glass fibers provides substantially increased overall strength and durability while providing increased flexibility and toughness in the region of the hinge connection between the ligation cover and the bracket base.
