IMPROVED EDGEWISE BRACKET Abstract An orthodontic bracket for use with an archwire to orthodontically treat a patient by imparting corrective forces to a tooth. The bracket includes a base portion for attachment to the tooth, mesial and distal tie wings extending from the base portion, each of which includes gingival and occlusal tips defining therebetween a buccolabial opening archwire slot. The archwire slots are in mutual alignment and define a reference line for orienting the bracket in parallel relation to the occlusal plane and the tie wings are oriented such that they areobliquely angled to the reference line. The gingival tips have surfaces that arein parallel alignment with the reference line and substantially equidistant therefrom, and the outer borders of the tie wings form a trapezoidal configuration as the tie wings are of unequal size.
