Abstract
  • The purpose of this study was to determine whether Cone Beam Computed Tomography (CBCT) synthesized cephalograms provide the same measurement accuracy and precision as conventional cephalograms. In Part I, cephalometric measurements of conventional and CBCT synthesized orthogonal or perspective projections of 10 skulls were compared with each other and with the actual skull measurements. In Part II, actual patient data was used to compare the three imaging modalities and both soft and hard tissue landmarks were utilized. This study demonstrated that most cephalometric measurements are not different for conventional and CBCT synthesized orthogonal and the perspective projections. Although there is a statically significant difference between mid-sagittal image measurements compared to actual skull measurements, these differences are very small .and are unlikely to have clinical relevance. Both of the projections can be used with an expectation of precision and accuracy similar to conventional cephalograms.
