ORTHODONTIC PALATAL ARCH WIRES FOR ACCURATE TRANSMITTAL OF CORRECTIONAL FORCES

摘要

ABSTRACTAn orthodontal palatal arch wire is provided for directional con-trol over a pair of brackets; each bracket being mounted on an oppos-ing molar in a patient's mouth. A resiliently flexible wire with adevice intermediate its length for producing corrective forces has atorquing band transversely mounted thereon. The torquing band is se-curable by an elastic device to a receiving unit on the lin-gual side of each bracket, so as to bear both forward and laterallyagainst the receiving unit for transmitting correctional forces there-between. A bracket is provided having a receiving unit with planarsurfaces capable of bearing flushly against a torquing band havingplanar forward and lateral bearing surfaces.
