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.
