The document discusses several generations of fixed functional appliances used in orthodontic treatment, including the Herbst appliance, various types of mandibular protraction appliances (MPA), the universal bite jumper, and the Ritto appliance. It also covers clinical considerations for using fixed functional appliances, such as appliance and archwire selection, initial patient adaptation, stepwise advancement if needed, and retention planning.
