摘要:
An orthodontic bracket has a base configured for attachment to a tooth surface, a bracket element with an arch wire slot attached to one side of the base, and a clip for securing the arch wire in the slot. The bracket element has a wall portion extending upward along one side of the arch wire slot. This wall portion has three indentations in a line parallel to the mesiodistal direction. There is a channel running entirely through the bracket element underneath the arch wire slot. The clip is substantially U-shaped and has three parallel protrusions shaped to fit within the three indentations of the wall portion, and a locking element. The clip is securable to the bracket by placing the clip through the channel and engaging the locking element onto the bracket element, and placing the protrusions into the indentations of the bracket element.
