ABSTRACT

砄bjective To develop a computer aided cephalometric analysis system running under the environment of Windows 9X/NT and based on screen input of landmark and contour line. Methods: The analysis system was made with object oriented method, the program was written with Visual Basic 6.0 and Access 8.0, and the data on the screen was converted. Results: Cephalometric landmark points and contour lines were input through computer screen, then analyzed (22 modes), superposed and managed statistically. The system showed the advantages of using popular hardware, good compatibility, easy expansion, friendly user interface, simple input of landmark points, artful input of cephalometric contour, intuition and diversification of superposition, deversification of statistic analysis, integrated information collection and convenient search. Conclusions: The system can be used in clinic and research.
