摘要：
An orthodontic bracket has a load bearing framework embedded in a plastic body. The framework includes archwire-engaging end portions that are coplanar with a lingual side of an archwire slot. The end portions faciliate control of movement of the bracket and the associated tooth. A buccolabial surface of the bracket is roughened to enhance aesthetics.
