This invention allows exact midface-related maxilla repositioning during mono- or bimaxillary surgery. The jaw positioning device comprises three splints (primary-, secondary- and reference splint) and three connection bars. The maxillary shift is planned preoperatively by model-surgery and encoded by the difference between primary- and secondary splint. There is no need for navigational systems or complex bone models based on three-dimensional imaging.
During surgery, the primary splint, which fits exactly to the occlusional surfaces of the maxillary teeth, is placed on the dental arch. The primary splint’s outer face features a definded surface profile, on which the reference splint is placed. In the next step, connection bars to three intraorally accessible points of the patient’s bony midface are fixed on the reference splint. In this way, the reference splint can be replaced exactly in a well-defined midface-related position, also without the primary splint. After LeFort I osteotomy, the maxilla can be precisely positioned at the target position by use of the secondary splint, that also fits exactly to the corresponding surface of the reference splint.
