Extraoral orthopedic traction device anchored on the chin and connected by elastic straps to a headcap. Delivers backward and upward force to the mandible to redirect growth and reduce mandibular prominence in growing Class III patients. Variants include occipital-pull (for horizontal control) and vertical-pull designs.
Mini chin cup versions can be integrated with intraoral appliances. Effectiveness depends on patient compliance and growth stage.
