ABSTRACT:
An adjustable bracket for use in orthodontic appliances. The bracket can be fixed to a band to surround a tooth, or to a wire mesh to be cemented directly to a tooth. The bracket has a base to be carried by the tooth, and a movable member to which wires are attached, and a retainer to fix the movable member to the base. In the preferred embodiment, the base and the movable member have spherical surfaces so that motion of the movable member can dispose the bracket at any desired angle in any plane for the desired torque, and in all embodiments the movable member is rotatable about the retainer through 360 degrees and can be set at any desired angle.
