ABSTRACT:
An improved edgewise orthodontic bracket is disclosed. In one embodiment, a bracket comprises a single pair of opposing T-shaped tie wings which define an archwire slot therebetween. Notches are provided on each of the mesial and distal sides of the center leg of each T-shaped tie wing for selectively receiving a ligating device. The notches are defined in the gingival/occlusal edges of the tie wings and comprise sloped portions that extend labially towards the archwire slot. Convex sidewall portions and convex floor portions are provided in the archwire slot adjacent to the notches. The body of the bracket is interconnected to a base that includes a continuous series of characters that serve as texturing to facilitate bonding of the bracket with a tooth. A discontinuous perimeter rail may be used at the edge of the base. A method for forming a bracket is also provided.
