ABSTRACT:
In accordance with the present invention, an improvement is provided in an annular orthodontic band for encircling the crown of a molar or bicuspid tooth wherein an antitip rest extends inwardly from a location along the mesial portion of the occlusal edge for a distance which is sufficient for the rest to be engageable with the occlusal surface of the tooth to prevent the mesial side of the band from sliding past the mesial ridge of the tooth. Additional antitip rests can be provided along the occlusal edge of one or more of the buccal, lingual and distal portions of the band for additional bodily support for proper positioning of the band. A ledge can be provided on the band for engagement by an instrument to seat the band on the tooth. A ball hook can be positioned on the gingival side of the ledge of a band for an upper tooth.
