Reproducibility assessment of Delaire cephalometric analysis using reconstructions from computed tomography.

Delaire computerized simplified Top12 analysis was reproducible for lateral cephalometric X-rays and for reconstructions obtained from CT scans with similar angle measures for a given patient. This analysis does not seem to be reliable for dry skulls without upper cervical spine. This study uses the example of one particular computerized cephalometric analysis in order to show that cephalometric analyses can be performed on lateral reconstructed cephalometric X-rays obtained from CT scans.
