Development of the 3D-cephalogram: a technical note.

INTRODUCTION: The authors developed the 3D-cephalogram via combination of 3D-CT and cephalometric analysis. METHODS: The 3D-cephalogram can directly express cephalometric data on the surface of skeletal structures in a manner similar to a conventional cephalogram. RESULTS: This analysis revealed complex facial asymmetries in particular, on either side of the mandible. Images displayed no geometric error due to magnification nor any overlap effect inherent in the conventional cephalogram. CONCLUSIONS: The 3D-cephalogram is helpful in instructing physicians, and patients themselves regarding pathological anatomy and treatment procedures.
