ABSTRACT:
An orthodontic attachment device especially useful for coupling interarch and intra-arch appliances to an archwire includes an elongated wire that extends alongside the archwire. The wire is fixed to a crimpable connector having a passageway that receives the archwire. Wall portions surrounding the passageway are deformable in directions toward the passageway in order to non-rotatably couple the device to the archwire. In certain embodiments, a pin having an offset portion is connected to the appliance at a location remote from the attachment device in order to increase free play of the appliance when the patient's jaws are opened.
