Study of computer-assisted Delaire cephalometric analysis system / 华西口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>The purpose of this study was to establish the computer -assisted Delaire cephalometric analysis system with WinCeph8.0 in order to simplify the procedure of manual Delaire cephalometric analysis.</p><p><b>METHODS</b>On the basis of the theory of Delaire cephalometric analysis and the program module of WinCeph8.0, the landmark points and the auxiliary line were defined, the measurement and analysis program were written, then the computer-assisted Delaire cephalometric analysis system was established. Paired t-test and dispersion analysis of the computer-assisted and manual measurements were taken.</p><p><b>RESULTS</b>Computer-assisted Delaire cephalometric analysis system was convenient and accurate to trace the landmark points and the auxiliary line. It was able to proceed the measurement and calculation automatically and display the analysis results. Statistical analysis showed that computer-assisted analysis was more accurate than manual analysis.</p><p><b>CONCLUSION</b>This study provided a convenient, simplified, accurate computer-assisted analysis platform for Delaire cephalometric analysis which facilitated its clinical application.</p>
