Distraction osteogenesis of the maxilla is indicated for jaw deformities in patients with extreme dysgnathia. First, extraoral appliances were introduced, and currently intraoral appliances are in vogue. These have significantly reduced the amount of physical and psychological stress placed on the patients. The direction of force vector may be varied according to the individual patient's requirements. This paper presents positioning devices for bilateral intraoral maxillary distraction plates, which have been developed to place maxillary distraction plates parallel to the direction of lengthening.
