导言：本研究的主要目的是通过与其他台式三维扫描仪VIVID910(柯尼卡美能达，日本东京)和R700(3Shape，哥本哈根，丹麦)进行比较，评估SureSmilleOraScanner(Orametrix，Richardson，德克萨斯州)的准确性和可靠性。一种基于激光的扫描仪，SLP250激光探测器(激光设计，底特律，密歇根州)，作为黄金标准。方法：使用5套牙列模型。首先，通过将OraScanner、VIVID910和R700创建的三维模型与SLP250的黄金标准三维模型进行比较，研究了每台扫描仪的精度。为了评估三维模型的可靠性，根据所有5组牙模基于相同表面的配准计算每个模型的壳/壳偏差。结果：与金标准相比，OraScanner、VIVID910和R700具有足够的准确性。在信度评估上，所有比较均无显著差异。结论：OraScanner系统具有完善的三维表面配准算法，可用于生成准确可靠的三维数字模型，供临床医生使用。
Introduction: The primary objective of this study was to assess the accuracy and the reliability of the SureSmile OraScanner (Orametrix, Richardson, Tex) by comparing it with other desktop 3-dimensional scanners: VIVID910 (Konica Minolta, Tokyo, Japan) and R700 (3Shape, Copenhagen, Denmark). A laser-based scanner, the SLP250 Laser Probe (Laser Design, Detroit, Mich), served as the gold standard. Methods: Five sets of dental casts were used. First, the accuracy of each scanner was studied by comparing the 3-dimensional models created by OraScanner, VIVID910, and R700 with the gold standard 3-dimensional models of the SLP250. To assess the reliability of the 3-dimensional models, the shell/shell deviation of each model was calculated based on the same surface-based registrations for all 5 sets of dental casts. Results: OraScanner, VIVID910, and R700 were sufficiently accurate when compared with the gold standard. In the assessment of reliability, there were no significant differences between all comparisons. Conclusions: The results showed that the OraScanner system has a sophisticated algorithm for 3-dimensional surface registration and can be used to generate accurate and reliable 3-dimensional digital models for use by clinicians.
