Self-ligating bracket

摘要

A self-ligating bracket includes a bracket body with a mesial and a distal channel. A spring clip includes a distal arm with a distal arm body and a distal finger and a mesial arm with a mesial arm body and a mesial finger. The spring clip is slidably secured within the bracket body by a sliding engagement of the distal arm with the distal channel and the mesial arm with the mesial channel. The spring clip is movable between an open position and a closed position wherein in the open position, the arch wire slot is unobstructed and in the closed position the mesial finger and distal finger extend into and across the arch wire slot to occlude the arch wire slot.

1. 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 from the mesial side, and a distal channel that extends into the bracket body from the distal side; and a spring clip comprising a distal arm comprising a distal arm body and a distal finger and a mesial arm comprising a mesial arm body and a mesial finger, wherein the distal finger extends in a plane different from the distal arm body and the mesial finger extends in a plane different from the mesial arm body, the spring clip is slidably secured within the bracket body by respective sliding engagement of the distal arm with the distal channel and the mesial arm with the mesial channel; wherein the spring clip is movable between an open position and a closed position wherein in the open position the arch wire slot is unobstructed and in the closed position the mesial finger and the distal finger extend into and across the arch wire slot to occlude the arch wire slot; and wherein when the spring clip is in the open position, the mesial finger is slidably received within the mesial channel and deformed within the mesial channel such that the mesial finger is generally coplanar with the mesial arm body and the distal finger is slidably received within the distal channel and deformed within the distal channel such that the distal finger is generally coplanar with the distal arm body and in the closed position, the mesial finger extends out of the mesial channel and the distal finger extends out of the distal channel.
