Final Treatment Planning
After tile completion of the presurgical periodontics, restorative dentistry, and orthodontics, the patient returns to the oral and maxillofacial surgeon’ for final presurgical planning. The evaluation completed at the initial patient examination is repeated. The patient’s facial structure and the malocclusion are reexamined. Presurgical photographs, radiographs, and presurgical
models are taken, a centric relation bite registration and face-bow recording for model mounting are completed, and computer images are obtained when available.
Model surgery on a duplicated set of presurgical dental casts determines the exact surgical movements necessary to accomplish the desired postoperative occlusion (Fig. 25-7). Prediction tracings of the anticipated surgical
movements provide a visual treatment objective of the desired skeletal movements and resulting postoperative soft tissue changes from the lateral perspective (Fig.5-8).
