Crimpable retraction loop

A crimpable retraction loop apparatus comprising:

• a first elongated coupling member;
• a second elongated coupling member;
• an elastically deformable bridge;
• the elastically deformable bridge comprising a first free end and a second free end;
• the first free end and the second free end being oppositely located to each other;
• the first elongated coupling member comprising a first elongated opening, a first concave crimping surface and a first archwire-receiving channel;
• the second elongated coupling member comprising a second elongated opening, a second concave crimping surface and a second archwire-receiving channel;
• the first free end being connected to the first elongated coupling member;
• the second free end being connected to the second elongated coupling member;
• the first elongated coupling member being connected to the second elongated coupling member by the elastically deformable bridge;
• the first archwire-receiving channel being delineated by the first elongated opening and the first concave crimping surface;
• the second archwire-receiving channel being delineated by the second elongated opening and the second concave crimping surface;
• the first elongated coupling member and the second elongated coupling member being substantially aligned with each other;
• the first concave crimping surface comprising a first lower portion and a first upper portion;
• the first lower portion and the first upper portion being offset from each other;
• the first lower portion and the first upper portion being separate from each other via the first elongated opening;
• the second concave crimping surface comprising a second lower portion and a second upper portion;
• the second lower portion and the second upper portion being offset from each other;
• and
• the second lower portion and the second upper portion being separate from each other via the second elongated opening.
