Title: CRIMPABLE RETRACTION LOOP
Abstract:
An accessory allows for straight archwires to be converted to looped archwires. The accessory has an archwire receiving channel which is defined between a first elongated coupling member and a second elongated coupling member. The archwire receiving channel is used for crimping the accessory to an existing archwire. An elastically deformable bridge, connected between the first elongated coupling member and the second elongated coupling member, imparts retraction or protraction once activated. The elastically deformable bridge is formed from one or more segments. Curved segments and linear segments are possible, which can be combined to form various shapes, for example omega loops and mushroom shapes. The first coupling member and the second coupling member have an angled lower portion and upper portion to facilitate engagement with existing archwires. Anchoring notches can also be used in conjunction with elastic bands for enhanced orthodontic corrections.
