    Abstract:
    In order to mobilize and reposition the maxilla when treating dentofacial deformities, the Le Fort I maxillary osteotomy is commonly used. Like other surgical procedures, this procedure is not without inherent difficulties. At times, it may be difficult to initially mobilize the maxilla after performing the osteotomies. Techniques used to help in the initial mobilization and downfracture of the maxilla from the pterygoid plates include digital pressure to the dentoalveolus, disimpaction forceps, spreaders, and other instruments. These techniques are similar in that they all apply a unidirectional downward vector of force on the maxilla and have various drawbacks. We present a technique that uses a 0.5-mm stainless steel traction wire to facilitate Le Fort I maxillary downfracturing by applying a forward and downward vector of force simultaneously. After vertical downfracture of the maxilla, lateral traction on the wire can be used to complete the pterygomaxillary disjunction. This technique has several advantages and is atraumatic, and requires no special instrumentation; thus, downfracturing of the maxilla is done with relatively little effort and minimal risk.
