Orthodontic bracket assembly

Claim 1

An orthodontic bracket assembly for use with an archwire to impart corrective forces on a tooth, including: a base pad for attachment to the tooth, a distal tie wing fixed to said base pad and including a gingival tip and an occlusal tip defining between them an archwire slot, a mesial tie wing fixed to said base pad and including a gingival tip and an occlusal tip defining between them an archwire slot, each of said distal and mesial tie wings having parallel distal and mesial sides, said archwire slots being in mutual alignment and providing a reference line for orientation parallel to the occlusal plane of a patient, said sides of said tie wings are inclined at an oblique angle to said reference line, whereby said tie wings can be generally vertically disposed parallel to the tooth long axis and still be inclined at an oblique angle to said reference line, said gingival tips and said occlusal tips of said tie wings having respectively top and bottom surfaces which are in mutual alignment parallel to said reference line and substantially equidistant therefrom, whereby said tie wings together form a rhomboidal configuration and the axis of said archwire slots bisects said tie wings so that said gingival tips and said occlusal tips are of equal size.
