AI Article Synopsis
- The study aimed to evaluate how well cone beam computed tomography (CBCT) synthesized cephalograms match traditional cephalograms and to establish a method for defining normal values in 3D assessments.
- A group of 10 adults with normal facial structures underwent imaging with both conventional and CBCT cephalograms, analyzing 21 angular and 12 linear measurements using statistical tests.
- Results indicated that most linear and angular measurements between the two methods did not show significant differences, suggesting that traditional 2D cephalometric norms can be adapted for 3D evaluations with some corrections for distortion.
Article Abstract
Purpose: This study was performed to assess the compatibility of cone beam computed tomography (CBCT) synthesized cephalograms with conventional cephalograms, and to find a method for obtaining normative values for three-dimensional (3D) assessments.
Materials And Methods: The sample group consisted of 10 adults with normal occlusion and well-balanced faces. They were imaged using conventional and CBCT cephalograms. The CBCT cephalograms were synthesized from the CBCT data using OnDemand 3D software. Twenty-one angular and 12 linear measurements from each imaging modality were compared and analyzed using paired-t test.
Results: The linear measurements between the two imaging modalities were not statistically different (p>0.05) except for the U1 to facial plane distance. The angular measurements between the two imaging modalities were not statistically different (p>0.05) with the exception of the gonial angle, ANB difference, and facial convexity.
Conclusion: Two-dimensional cephalometric norms could be readily used for 3D quantitative assessment, if corrected for lateral cephalogram distortion.
