The anchor brackets fix the traction rodonto bony foundation of a patient's jaw.

A tractionbracket freely slides along the traction rod, and the traction bracket is fixed to a movable bony segment. A translator nut is threaded onto the traction rod to abut against a side of thetraction bracket. Selective rotation of the translator nut pushes the traction bracket to movethe movable bony segment a predetermined distraction distance. When assembled and installed, the working components of the curved distractor are exposed in the oral cavity tothe facial side for easy access. Tools are provided to operate the translator nut.
