Short lingual osteotomy without fixation : A new strategy for mandibular osteotomy called the “ Physiological Positioning Strategy ”

This article advocates the physiological positioning strategy (PPS) as a novel alternative treatment strategy to conventional orthognathic surgeries. Eighteen patients with skeletal mandibular prognathism were treated with surgery using the PPS. SNB and FMA as well as the Me position were measured after surgery to determine the skeletal stability, and the changes in the angle and perpendicular length of the upper and lower central incisors were also calculated after surgery to determine the dental stability. Excellent skeletal and dental stabilities were confirmed. The width of the jaw opening recovered early, and one temporomandibular joint disorder case was observed. Short lingual osteotomy with the PPS represents an effective new treatment approach for mandibular jaw deformities.
