An orthodontic system includes an orthodontic bracket that has a base configured to be attached to a surface of a tooth. The bracket includes a rotatable module having a first member and a second member, the rotatable module being rotatably coupled to the base, the first and second members being spaced apart to define an archwire slot configured to receive an archwire. The base includes a miniature gear system to drive the rotatable module relative to the base.
