Abstract
The invention is directed to an orthodontic bracket assembly having a trapezoidal configuration for ease of positioning and aligning the bracket on the tooth. The bracket assembly comprises a pair of tie wings, each having non-parallel mesial and distal edges and further having an occlusal edge substantially parallel to the occlusal plane and to the sight line of the archwire slot. The edges of the tie wings form sight lines that intersect at a focal point located at the tip of the root tooth to assist in positioning the bracket. The edges of the tie wings also are substantially parallel to the tooth edges to assist in aligning and positioning the bracket on the tooth. Further, a V groove is provided along the longitudinal axis of the bracket and forms a sight line that also intersects the focal point to facilitate alignment of the bracket during mounting. The occlusal edge of the tie wings is parallel to the sight line of the archwire slot and both form sight lines that are substantially parallel to the edge of the tooth. The various sight lines forming a trapezoidal configuration for ease in positioning and aligning the bracket during mounting.
