Abstract
A treatment technique for the orthodontic management of extraction cases, using a modified Johnson twin arch wire, has been described. The areas in which this technique differs from the conventional twin arch wire technique are (1) the use of sectional appliances in the distal movement of canines, (2) the use of palatal anchorage accompanying the sectional arch wires, (3) the use of twin-tie attachments and round wires in the mandibular dental arch, and (4) the utilization of extraoral anchorage to augment the intraoral anchorage.
