Claim 9:
10. An orthodontic appliance as claimed in claim 1 and wherein the individual archwire couplers on the same archwire are axially slidably movable along the respective archwire between an adjacent mesial orthodontic bracket and an adjacent distal orthodontic bracket when the individual fasteners are not tightened into frictional engagement with the respective archwire; and
cooperation of a generally rectilinear cross-sectional configuration of the respective archwire, and a generally rectilinear peripheral configuration of the archwire receiving region defined by the archwire coupler and a distal end of fastener prevents axial rotation of the archwire coupler relative to the archwire; and
the distal end of the fastener maintains the respective archwire in the generally rectilinear archwire receiving region defined in the archwire coupler.
