A self-ligating bracket and a clip for a self-ligating bracket include a first clip arm and a second clip arm. The first arm terminates in a mesial arm, a distal arm, and a middle arm. The clip is moveable between an open position in which the arch wire slot is accessible and a closed position in which the arch wire slot is occluded. The second clip arm extends past the first, second, and third arms of the first clip arm. The self-ligating bracket includes a bracket body with an arch wire slot and the second clip arm positioned lingually of the arch wire slot.

Self-ligating bracket

A self-ligating bracket includes a bracket body and a spring clip. The bracket body includes a mesial channel, a distal channel, a center channel, and an arch wire slot. The spring clip includes a distal arm, mesial arm, and a center arm which are moveably within the mesial channel, distal channel, and center channel between an open position and a closed position to occlude the arch wire slot.

A self-ligating bracket include a bracket body with an arch wire slot. A mesial recess is located at a mesial side of the bracket body and extends into the bracket body from the arch wire slot. A distal recess is located at a distal side of the bracket body and extends into the bracket body from the arch wire slot. A central ridge defines a ridge surface separated from the lateral ledges respectively by mesial and distal walls. A clip includes a first arm and a second arm connected by a U-shaped portion. The first arm terminates in a mesial arm, a distal arm, and a middle arm. The clip is moveable between an open position in which the arch wire slot is accessible and a closed position in which the arch wire slot is occluded.

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.

Clip for a self-ligating bracket

An orthodontic bracket system includes a bracket and a clip. During closing, an arm of the clip rides down against an inclined rear surface of a first tie wing and a portion of the clip bends resiliently, exerting a force that locks a locking edge portion of the clip in a recess beneath second tie wings. During opening, the arm rides up against the inclined rear surface of the first tie wing as the locking edge portion of the clip is removed from the recess beneath the second tie wings. The clip is then moved to an open position to permit placement and removal of the archwire and held in that position.
