A self-ligating bracket comprising:
- a bracket body having a mesial side and a distal side, the bracket body comprising an arch wire slot that extends from the mesial side to the distal side of the bracket body, a mesial channel that extends into the bracket body, a distal channel that extends into the bracket body, and a center channel extending into the bracket body between the mesial channel and the distal channel;
- a spring clip comprising a distal arm comprising a distal arm body and a distal finger, a mesial arm comprising a mesial arm body and a mesial finger, and a center arm comprising a first center arm body and a second center arm body connected by a center arm bar that define a center opening through the center arm;
- and
- a stop projection extending from the center channel and received within the center opening of the spring clip;
