Intraoral scanners have been widely used in the application of dentistry. Accuracy includes trueness and precision; they have an important position in the assessment of intraoral scanners. The existing standard models are divided into the inlay and the crown, but the operation is relatively complicated. In this study, in order to simplify the current standard model, we designed a new integration model to compare the accuracy of two intraoral scanners (CEREC and TRIOS) and an extraoral scanner (SHINING). The coordinate measuring machine measured value is the gold standard. Values of the length and angle were analyzed by converting the scanned digital impressions into an STL (standard triangulation language) format to evaluate the accuracy of the intraoral scanner and to verify the feasibility of the designed model. The result shows that the integration model can be successfully scanned and imaged. In the case of the powder-free integration model, intraoral scanner precision, trueness, 3D fitting, and imaging are better than the extraoral scanner. It can be seen straightly from the measurement result and the 3D fitting result that the intraoral scanner can acquire the shape of the standard model integrally with good repeatability. Therefore, it can be concluded that TRIOS is superior to CEREC and SHINING in accuracy, and the integration model is feasible as a reference in the examination of intraoral scanners. The performance of the newly designed integration model that can be scanned is clinically significant, suggesting that this model can be used as a standard reference model.

单牙模型的设计及其在口腔扫描系统评估中的应用

口腔内扫描仪已广泛应用于牙科应用中。准确度包括真实性和精确度;他们在口腔内扫描仪的评估中占有重要地位。现有的标准款分为镶嵌和表冠,但操作相对复杂。在这项研究中,为了简化当前的标准模型,我们设计了一个新的集成模型来比较两个口内扫描仪(CEREC 和 TRIOS)和一个口外扫描仪(SHINING)的准确性。三坐标测量机测量值是金标准。通过将扫描的数字印模转换为 STL(标准三角测量语言)格式来分析长度和角度的值,以评估口内扫描仪的准确性并验证设计模型的可行性。结果表明,集成模型可以成功扫描和成像。在无粉集成模型的情况下,口内扫描仪的精度、真实性、3D拟合和成像优于口外扫描仪。从测量结果和3D拟合结果可以直接看出,口内扫描仪可以整体获取标准模型的形状,重复性好。因此,可以得出结论,TRIOS在准确性上优于CEREC和SHINING,集成模型作为口腔扫描仪检查中的参考是可行的。新设计的可扫描集成模型的性能具有临床意义,表明该模型可作为标准参考模型。在无粉集成模型的情况下,口内扫描仪的精度、真实性、3D拟合和成像优于口外扫描仪。从测量结果和3D拟合结果可以直接看出,口内扫描仪可以整体获取标准模型的形状,重复性好。因此,可以得出结论,TRIOS在准确性上优于CEREC和SHINING,集成模型作为口腔扫描仪检查中的参考是可行的。新设计的可扫描集成模型的性能具有临床意义,表明该模型可作为标准参考模型。在无粉集成模型的情况下,口内扫描仪的精度、真实性、3D拟合和成像优于口外扫描仪。从测量结果和3D拟合结果可以直接看出,口内扫描仪可以整体获取标准模型的形状,重复性好。因此,可以得出结论,TRIOS在准确性上优于CEREC和SHINING,集成模型作为口腔扫描仪检查中的参考是可行的。新设计的可扫描集成模型的性能具有临床意义,表明该模型可作为标准参考模型。从测量结果和3D拟合结果可以直接看出,口内扫描仪可以整体获取标准模型的形状,重复性好。因此,可以得出结论,TRIOS在准确性上优于CEREC和SHINING,集成模型作为口腔扫描仪检查中的参考是可行的。新设计的可扫描集成模型的性能具有临床意义,表明该模型可作为标准参考模型。从测量结果和3D拟合结果可以直接看出,口内扫描仪可以整体获取标准模型的形状,重复性好。因此,可以得出TRIOS在准确性上优于CEREC和SHINING的结论,集成模型作为口腔扫描仪检查的参考是可行的。新设计的可扫描集成模型的性能具有临床意义,表明该模型可作为标准参考模型。该集成模型可作为口腔内扫描仪检查的参考。新设计的可扫描集成模型的性能具有临床意义,表明该模型可作为标准参考模型。该集成模型可作为口腔内扫描仪检查的参考。新设计的可扫描集成模型的性能具有临床意义,表明该模型可作为标准参考模型。
