Teeth repositioning systems and methods

An orthodontic appliance comprising:

• an arch shaped member configured to extend along a patient's teeth;
• and
• a plurality of arms connected to and extending away from the arch shaped member, each of the arms having a connector portion disposed at a distal region of the arch shaped member, the connector portion configured to be coupled to one of the teeth, the plurality of arms including:
• a first arm having a first geometry configured to provide flexibility between the arch shaped member and the tooth to which the first arm is coupled,
• a second arm having a second geometry configured to provide a rigid connection between the arch shaped member and the tooth to which the second arm is coupled, thereby anchoring the orthodontic appliance, and
• wherein the arch shaped member and the plurality of arms comprise a unitarily formed structure.

An orthodontic appliance, the appliance comprising:

• an elongate member configured to extend along a backside of a patient's teeth;
• and
• a plurality of arms spaced apart along the elongate member, each of the arms including:
• a first portion configured to be coupled to a corresponding one of the teeth,
• a second portion adjacent the first portion along a corresponding one of the arms, wherein the second portion is either (i) resiliently flexible such that, when the first portion is coupled to a corresponding tooth, the second portion is configured to move from a loaded state toward an unloaded state, thereby repositioning the corresponding one of the teeth from an original position toward a desired final position, or (ii) rigid such that the corresponding arm anchors a corresponding tooth in an initial position, and
• wherein the elongate member and the arms comprise a unitarily formed structure.
