An orthodontic bracket, such as a bracket made of Stainless steel and stainless material, is provided with a liner that changes the dimensions of the bracket systementirely. A portion of the liner may project beyond the bracket body and may include 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 arch" wire slot in order to urge-the attached tooth to rotate as needed about its long axis. The liner is secured to the bracket body in such "a manner that the bracket body is thereafter held injtight lock with compression using a ball and socket mechanism. The liners have various different measurements built- in such as tip, torque and in-out measurements and can also inverted to have opposite dimensions effective while placing the arch- wire. The clinician can pull out the liner from the base bracket by using instruments such as Damon TM opening instrument or even explorer and then change to a different insert if warranted.
