A study to assess the reliability and identification of craniofacial landmarks in CBCT generated 2D cephalograms compared to digital cephalograms

Abstract

Introduction: Lateral cephalograms are widely used in Orthodontics as a vital tool for treatment planning in orthodontics. The projection and identification errors of cephalometric analyses determine their reliability. In this study, we sought to ascertain whether the method utilized to synthesize CBCT cephalograms affected the repeatability of the cephalometric measurements, as well as whether cephalometric measurements made on patients' CBCT-synthesized cephalograms have been comparable with measurements made on conventional cephalograms. Methods:CBCT-generated cephalograms along with the Conventional digital cephalograms have been selected and parameters were studied using Steiner's analysis. 7 Linear and 9 angular measurements were done. The linear and angular measurements required for different analyses were determined for cephalometric analysis software named Nemoceph (updated version 7). Results: The values of the 2 imaging modalities do not show any statistically significant difference. The correlation coefficient/r-value shows that both Digital cephalograms and CBCT cephalograms are highly reliable.Conclusion: So, we can conclude that both conventional digital lateral cephalogram and CBCT-generated cephalogram can be readily used for craniofacial landmarks identification.
