ABSTRACT:
An orthodontal palatal arch wire is provided for directional control over a pair of brackets; each bracket being mounted on an opposing molar in a patient's mouth. A resiliently flexible wire with a device intermediate its length for producing corrective forces has a torquing band transversely mounted thereon. The torquing band is securable by an elastic device to a receiving unit mounted on the lingual side of each bracket, so as to bear both forward and laterally against the receiving unit for transmitting correctional forces therebetween. A bracket is provided having a receiving unit with planar surfaces capable of bearing flushly against a torquing band having planar forward and lateral bearing surfaces.
