An orthodontic appliance comprises a base portion adapted to be affixed to a patient's tooth and an upper portion including a flexible and resilient hook for forming a tubular channel for receiving an archwire. The upper portion includes a flange affixed to the hook, and is sized and shaped to connect to loops of an elastomeric power chain.

Low profile bracket with elastomeric chain

A tool for insertion and removal of an archwire into low-profile orthodontic brackets includes a handle section and at least one end section having a pair of claws separated by a gap. Each of the pair of claws has a pair of lobes with internal pathways for accommodating an archwire. This enables the archwire to be alternately pushed into and pulled away from an orthodontic bracket.
