ORTHODONTIC BRACKET WITH LINED ARCHWIRE SLOT AND COVER

摘要

A triple wing orthodontic bracket, bracket cover, and method of use is disclosed. The bracket has a slot liner for reducing friction between an archwire and the bracket, wherein the liner is flared at its ends. The bracket cover has: a rod-shaped hinge for rotating in recesses between a bracket base, and bracket wings on one of a gingival and occlusal bracket side, a slot cover, and a cross member for rotating the slot cover between covering a bracket archwire slot, and uncovering the slot, wherein the rotation pivots the hinge in the recesses. The hinge and recesses frictionally engage one another, wherein in a first position, the hinge attaches and detaches from the bracket, and after pivoting the hinge to another position in the recesses, the hinge is secured therein. Interaction between the hinge and the recesses may cause the slot cover to move to cover the slot.
