ABSTRACT:
An orthodontic appliance, such as a buccal tube, an edgewise bracket or an edgewise bracket having rotating pads thereon, is molded either from a ceramic material or metal. When a ceramic material is used, the color of the appliance may be coordinated with that of a tooth. The appliance has a domed outwardly facing surface which is entirely curved in both the length and width directions and which is free of angular edge surfaces. The appliance may be adapted either for bonding directly to a tooth surface or for welding to a tooth and circling band. When the appliance is bonded directly to the tooth surface, a bonding material is employed. When bonded directly to the tooth, the appliance has an aperture formed with an undercut portion therein at the point of bonding which forms the bonding material contained within the aperture thereby causing the bonding material and appliance to be mechanically interlocked.
