Method to verify the accuracy of model surgery and prediction tracing.

Accuracy of cephalometric tracings and model surgeries is of utmost importance in planning for orthognathic surgery. The technique described allows surgeons to verify position of the models by superimposing a cephalogram of the mounted models over that of the patient. It also reduces the chance of error during actual surgery by placing models in centric relation. Therefore, the possibility of intraoperative complications, and thus longer operating times, is minimized.
