Labial attachment device for use with orthodontic auxiliary and lingual appliance system
The present disclosure provides an assembly and system allowing for secure use of an orthodontic auxiliary, particularly a bite corrector, with lingually bonded appliance systems. In one aspect, the disclosure features an orthodontic assembly including a banded tube, a force module, a connector coupling the force module to the tube, and an attachment device secured to the labial surface of an anterior tooth and connected to mesial, outer end of the force module.
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.
2. The orthodontic assembly of claim 1 , wherein the opposite end of the force module includes a loop configuration, and wherein a least a portion of the loop configuration is received in the recess.
3. The orthodontic assembly of claim 1 , wherein the mesial-distal segment and the biasing segment cooperate to limit rotation of the force module about a generally mesial-distal reference axis.
4. The orthodontic assembly of claim 1 , wherein the first attachment device is adapted to be secured to a single cuspid tooth.
5. The assembly of claim 1 , further comprising a second attachment device secured to a location distal from the first attachment device, wherein the second attachment device is connected to the first attachment device with a ligature.
6. The orthodontic assembly of claim 1 , wherein the upper arch appliance is a banded tube including a body defining a passage and band configured to at least partially encircle a molar tooth, generally above the height of contour.
