The plurality of tiewings may be located on the occlusal side of the orthodontic bracket, and may include a center post between the tiewings, for placement reference and ligation of the orthodontic bracket. A hook may be provided on the gingival side of the orthodontic bracket for anchorage and ligating of the orthodontic bracket, and the tiewings may be provided on the occlusal and gingival side of the orthodontic bracket. The posts may be provided on the gingival side, or on the occlusal and gingival sides of the orthodontic bracket, to assist in bracket placement and to direct a ligature over or under an archwire occupying the archwire slot during treatment, as desired. A biocompatible wire clip ligature and biocompatible cap ligature are also provided for retaining the archwire in the archwire slot, and the bonding base may have a recessed number for identification of the tooth location of the orthodontic bracket molded therein.
