The aim of this study was to evaluate the accuracy of two intraoral scanners used in the dental office. A molar fixed in a typodont was prepared for a ceramic onlay. The preparation was scanned using a high-resolution scanner (reference scanner) and saved as stereolithography (STL) format. The prepared resin molar was scanned again using the intraoral scanners, and all the scans were saved as well in STL format. All STL files were compared using metrology software (Geomagic Control X). Overlapping the meshes allowed the assessment of the scans in terms of trueness and precision. Based on the results of this study, the differences of trueness and precision between the intraoral scanners were minimal.
本研究的目的是评估牙科诊所使用的两种口腔内扫描仪的准确性。将固定在牙模型上的一颗磨牙预备为陶瓷高嵌体。使用高分辨率扫描仪（参考扫描仪）对该预备体进行扫描，并保存为立体光刻（STL）格式。再次使用口腔内扫描仪对制备好的树脂磨牙进行扫描，所有扫描结果也保存为STL格式。使用计量软件（Geomagic Control X）对所有STL文件进行比较。通过网格重叠可以从准确性和精确性方面评估扫描结果。基于本研究的结果，口腔内扫描仪之间在准确性和精确性方面的差异极小。
