Aesthetics is a challenging aspect to restore for both dentists and dental technicians. One of the characteristics of aesthetic restoration is the shade. The purpose of the study is to assess the accuracy of the shade selection feature of intraoral scanners (CEREC Omnican, 3Shape TRIOS) in comparison with an already established method-the VITA Easyshade V spectrophotometer (VE)-and test if there is any significant difference between the three devices. To conduct this in vitro study, the VITA Classical shade guide was used. The intraoral scanners would not be able to scan the VITA Classical as it is, hence, a study model (SM) was fabricated. To be able to test the accuracy of the intraoral scanners (IOSs) in detecting the dental color, a spectrophotometer had to be included in the study, as it was shown that it is the most accurate instrument for this purpose. Therefore, for the current study, the VITA Easyshade V spectrophotometer (VITA Zahnfabrik, Bad Sackingen, Germany) was selected. The accuracy of the three devices when measuring the shade of the study model was calculated as a percentage. When comparing the primary results of the VE and the results obtained by the Omnicam and TRIOS, the latter is the most accurate (26.67%), whereas the other two scored 20%. The study also revealed the limitations of the instrumental devices that were used. First, both the VE and IOSs obtained unexpectedly low accuracy results. Possibly, the material VC is made of influenced the final accuracy values, but in practice, on a daily basis, dental materials represent a factor that cannot really be controlled.
美学修复对于牙医和牙科技师来说都是一个具有挑战性的方面。美学修复的特点之一是颜色。本研究的目的是评估口腔内扫描仪（CEREC Omnican、3Shape TRIOS）的颜色选择功能与已确立的方法——VITA Easyshade V分光光度计（VE）相比的准确性，并测试这三种设备之间是否存在显著差异。为了进行这项体外研究，使用了VITA经典比色板。由于口腔内扫描仪无法直接扫描VITA经典比色板，因此制作了一个研究模型（SM）。为了能够测试口腔内扫描仪（IOS）检测牙齿颜色的准确性，研究中必须纳入一台分光光度计，因为事实证明它是用于此目的最准确的仪器。因此，在本研究中，选择了VITA Easyshade V分光光度计（德国巴德萨克京的VITA Zahnfabrik公司）。将三种设备测量研究模型颜色时的准确性计算为百分比。在比较VE的主要结果与Omnicam和TRIOS获得的结果时，后两者最为准确（26.67%），而另外两者的得分是20%。该研究还揭示了所使用仪器设备的局限性。首先，VE和IOS都出人意料地获得了较低的准确性结果。可能是制作VC的材料影响了最终的准确性数值，但在实际日常操作中，牙科材料是一个难以真正控制的因素。
