The wall that is engaged by the retainer member end preferably in narrower than the bracket body and may comprise a small piece of the spring material used for the retainer member welded to the bracket body. The engaging faces of the retainer member and the retainer slot may be inclined to retain the retainer member in the slot-closed position.

Abstract: An orthodontic appliance for counteracting rotational forces acting on a tooth where such forces originate from the action of an arch wire on the surface mounted conventional orthodontic bracket, said arch wire forces being primarily intended for the linear translation of the tooth. Rotational forces are counteracted by means of a lever arm that is rigidly attached to the conventional orthodontic bracket and in contact with the arch wire at a point spaced apart from the junction of the arch wire and the orthodontic bracket. The counteracting forces generated by the lever arm are proportional only to the rotational forces induced in the tooth by the force from the arch wire. The lever arm may also be configured with a shank capable of being inserted in a rectangular hole located in the conventional orthodontic bracket. Such an appliance is capable of being positively locked into the aforementioned rectangular hole by means of a deformable tail section.
