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.
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.
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.
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.
本研究的主要目的是通过与其他台式三维扫描仪（日本 Konica Minolta 的 VIVID910 和丹麦 3Shape 的 R700）比较，评估 SureSmile OraScanner（Orametrix，Richardson，Tex）的准确性和可靠性。激光扫描仪 SLP250 Laser Probe（Laser Design，底特律，密歇根州）作为金标准。
使用了五组牙模。首先，通过比较 OraScanner、VIVID910 和 R700 创建的三维模型与 SLP250 的金标准三维模型，研究了每个扫描仪的准确性。为了评估三维模型的可靠性，根据所有五组牙模的相同基于表面的配准，计算了每个模型的壳/壳偏差。
与金标准相比，OraScanner、VIVID910 和 R700 具有足够的准确性。在可靠性评估中，所有比较之间均无显著差异。
结果表明，OraScanner 系统具有先进的三维表面配准算法，可用于为临床医生生成准确可靠的三维数字模型。
