Abstract
An orthodontic bracket, such as a bracket made of ceramic material, is provided with a liner that enhances sliding mechanics between the bracket and an archwire. A portion of the liner projects beyond the bracket body and optionally includes an occlusal, gingival or lingual section that extends over a mesial or distal side of the bracket body. A bottom surface of the liner is located a distance from a bottom wall of a channel receiving the liner, and the distance optionally varies along the length of the archwire slot in order to urge the attached tooth to rotate as needed about its long axis. The liner is bonded to the bracket body in such a manner that the bracket body is thereafter held by the liner in compression.
