Objectives of the Study: were (1) to develop a three-dimensional cephalometric analysis scheme applicable to assessing dentofacial deformities; and (2) to create a normative database of three-dimensional cephalometric measurements for adult North Karnataka population. Materials and Methods: A cross-sectional study was conducted on 40 male and 40 female adults with normal balanced facial profile and occlusion. Cone-beam computed tomography (CBCT) images obtained in digital imaging and communications in medicine format and the anatomic Cartesian three-dimensional cephalometric reference system according to Swennen et al. was used to standardize the reference planes. Cephalometric analysis was performed using various landmarks. New three-dimensional cephalometric analyses appropriate for orthognathic surgery as well as new parameters were used in this study. Results: The cephalometric norms generated in this study were comparable with those reported in the literature for conventional two-dimensional cephalometric analysis and unique features of North Karnataka population. The results showed significant differences between males and females in most of the facial measurements (P < 0.0001). Conclusion: This is the first database of three-dimensional cephalometric norms based on CBCT of the North Karnataka population. Norms generated were comparable with those reported in the literature with the conventional two-dimensional cephalometry: More accurate and reliable. Moreover, three-dimensional cephalometric analysis has the potential of incorporating new measurement methods that are difficult if not impossible in two-dimensional cepholmetric analysis. This method of cephalometric analyses can be useful in diagnosis and treatment planning for patients with dentofacial deformities. |
