【摘要】 目的　对牙颌模型三维激光扫描系统的可靠性进行研究 ,并为其临床应用提供科学依据。方法　利用D .0 1-L - 3DSCANNER系统扫描和测量了 30例基本正常石膏模型。采用三种方法检验了牙颌模型三维激光扫描系统的可靠性 ,并与手工测量进行了比较。结果　可靠性研究三个方法的结果显示无显著性差异 ;与手工测量的比较无显著性差异 ,但牙颌模型三维激光扫描系统具有一些手工测量所无法达到的功能。结论　牙颌模型三维激光扫描系统可靠性强 ,稳定性好 ,可应用于临床、科研、教学中的牙颌模型测量更多还原

【Abstract】 Objective To test the reliability of the three-dimensional dental cast laser scanner for clinical applications.Methods 30 dental casts were scanned and measured to test the reliability of the three-dimensional dental cast laser scanner using the D.01-L-3D SCANNER system.And it was also compared with the direct manual measurement.Results There were no significant differences between scanming and manual.Conclusion The three-dimensional dental cast laser scanner is a highly reliable system.It can be used in analysis and storage of the dental cast.更多还原
