During orthodontic-surgical treatment of dentofacial deformities, centric relation of the mandibular condylar head to the fossa articularis must be maintained. Intraoperative application of the condylar positioning appliance, in combination with different surgical splints, allows three-dimension adjustment of the jaw segments. The condylar positioning appliance can be used in osteotomies of the mandible alone, is isolated Le Fort I osteotomies, or in simultaneous osteotomies of the maxilla and mandible.
