Planning orthognathic surgery with three-dimensional models.

Abstract

Computerized imaging to provide the perspective of the third dimension is helpful for preoperative evaluation and has been introduced for a variety of indications. Calculated from original computerized tomographic scans, deformities in skeletal and soft tissue profiles can be visualized on a television monitor. A method of fabricating three-dimensional skeletal models that can be used for planning orthognathic surgery has been developed. Mandibular and maxillary surgical movements can be simulated exactly, and osteosynthesis materials can be chosen, adapted, and prepared to save time intraoperatively.
