<p>A twin tie wing orthodontic bracket (10) having a pair of substantially parallel spaced tie wings (12, 13) extending from a base portion (11) adapted to be attached to a tooth, and a horizontally opening buccolabially extending archwire slot (34) and cutouts (38, 39) at the mesial and distal sides (16, 17) of the bracket at the archwire slot and the buccolabial face which increases the interbracket distance and thereby increases the range of the archwire and decreases the force the archwire exerts on the brackets. <IMAGE></p> |
