Abstract

Introduction: Three-dimensional (3D) analysis is essential for making a precise diagnosis of craniofacial morphology. Two-dimensional (2D) x-ray films are used to understand 3D structures. However, 2D images have several limitations. This article proposes a new type of cephalometric analysis by using 3D computed tomography. Methods: Axial images of 30 subjects (16 men; mean age, 19.2 years; 14 women, mean age, 20.5 years) were reconstructed into 3D models by using Vworks 4.0 (Cybermed, Seoul, Korea). The 3D models were measured with Vsurgery (Cybermed). The zygoma, maxilla, mandible, and facial convexity were analyzed. Results: The measurements were compared with Korean normal averages, and no statistically significant differences were found. Landmark identification was reproducible. Conclusions: Three-dimensional computed tomography can provide information for use in diagnosis and treatment planning.
