In this study, we evaluated the repeatability of scans of stone models and impressions of abutment teeth using a blue LED scanner and compared the findings between different abutment teeth types. For the stone models as well as impression of the canines, premolars, and molars, we generated 10 color-difference-maps and reports for each tooth type (n=10 per tooth type). One-way analysis of variance (ANOVA) and independent t-tests were performed to evaluate the repeatability of scans of the stone models and impressions obtained from a blue LED scanner. Our results indicate a high repeatability of scans of stone models and impressions of abutment teeth using the blue LED scanner and suggest a possible clinical advantage for scanning impressions of different abutment teeth types.
在本研究中，我们使用蓝色发光二极管（LED）扫描仪评估了牙石模型和基牙印模扫描的可重复性，并比较了不同类型基牙之间的结果。对于犬齿、前磨牙和磨牙的牙石模型以及印模，我们针对每种牙齿类型生成了10张色差图和报告（每种牙齿类型n = 10）。进行了单因素方差分析（ANOVA）和独立t检验，以评估从蓝色LED扫描仪获得的牙石模型和印模扫描的可重复性。我们的结果表明，使用蓝色LED扫描仪对牙石模型和基牙印模进行扫描具有很高的可重复性，并表明扫描不同类型基牙印模可能具有临床优势。
