ABSTRACT:
A twin tie wing orthodontic bracket having a pair of substantially parallel spaced tie wings extending from a base portion adapted to be attached to a tooth, and a horizontally opening buccolabially extending archwire slot and cutouts at the mesial and distal sides 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.
