1. An orthodontic assembly for applying therapeutic forces between a patient's upper and lower dental arches in the absence of a labially bonded archwire, the orthodontic assembly comprising:
a connector for coupling to an upper arch appliance;
a first attachment device comprising a base having a tooth-facing surface adapted for bonding to a labial surface of an anterior tooth and comprising a facial surface and a mounting bar coupled to and spaced from the facial surface of the base the mounting bar comprising:
a first end attached to the facial surface of the base by a first strut;
a second end attached to the facial surface of the base by a second strut;
a mesial-distal segment; and
a biasing segment,
wherein the mesial-distal segment and the biasing segment are between the first end and the second end, wherein the mesial-distal segment and the biasing segment cooperate to define a first recess, wherein the second strut cooperates with the mesial-distal segment to provide a second recess, wherein the biasing segment extends at an acute angle relative to the mesial-distal segment; and
a force module having two opposing ends, with one end adapted for coupling to the connector and the opposite end adapted for coupling to the mounting bar of the first attachment device.
