Abstract
An orthodontic appliance includes a pin and a bracket. The pin has first and second portions joined by a bight. The first portion of the pin includes a pair of tie wings. The bracket includes a base with a pair of arms extending therefrom terminating in tie wings. A platform is positioned on the base between the arms. A first slot separates the tie wings. A second slot extends generally perpendicularly to the first slot through both arms and the platform. In use, the base of the bracket is attached to a tooth, an archwire is positioned in the first slot and the second portion of the pin is inserted through the second slot, such that the tie wings are adjacent the first slot. A ligature tie is then positioned about the tie wings to hold the archwire in place. In an alternative embodiment, an extension on the pin is bent about a portion of the bracket to secure the bracket to the archwire. The ligature tie is eliminated.
