Development and study of three-dimensional CT scanning system for dental cast measurement and analysis / 华西口腔医学杂志

<p><b>OBJECTIVE</b>To develop a computer assisted CT scanning system for 3D dental cast measurement and to study its reliability.</p><p><b>METHODS</b>20 dental stone casts were scanned by helical CT and captured a series digital sliced radiographs of them. The program which was developed by Visual C 6.0 language and run under the Windows surroundings rebuilt the 3D graphics and measured the coordinate of the dental cast. These dental casts were scanned and measured to test the reliability of the system, contrasting with manual measurement.</p><p><b>RESULTS</b>There was no significant difference between 3D CT scanning and manual measurement (P > 0.05).</p><p><b>CONCLUSION</b>The system is a valuable computer assisted system for clinical diagnosis and treatment of malocclusion.</p>
