This study aimed to investigate the overall and regional accuracy (trueness and precision) of digital three-dimensional (3D) facial scans obtained from four tablet-based applications, which were (Bellus) the Bellus Dental Pro® (Bellus3D, Inc. Campbell, CA, USA), (Capture) the Capture®: 3D Scan Anything (Standard Cyborg, Inc. San Francisco, CA, USA), (Heges) the Heges® (by Marek Simonik, Ostrava, North Moravia, Czech Republic), and (Scandy) the Scandy Pro 3D Scanner® (Scandy LLC, New Orleans, LA, USA).
A mannequin's face was marked with 63 landmarks. Subsequently, it was scanned 5 times using each scan application on an iPad Pro® (Apple Inc., Cupertino, CA, USA). The digital measurements were obtained with MeshLab® (CNR-ISTI, Pisa, Tuscany, Italy) and compared to the manual measurements using a digital vernier calliper (Truper Herramientas S.A., Colonia Granada, Mexico City, Mexico). The absolute mean difference and the standard deviation of the dimensional discrepancies were calculated. Moreover, the data were analysed by using one-way ANOVA, Levene's test, and Bonferroni´s correction.
The absolute mean trueness values were Bellus 0.41 ± 0.35 mm, Capture 0.38 ± 0.37 mm, Heges 0.39 ± 0.38 mm, and Scandy 0.47 ± 0.44 mm. Moreover, precision values were Bellus 0.46 mm, Capture 0.46 mm, Heges 0.54 mm, and Scandy 0.64 mm. Comparing the regions, Capture and Scandy showed the highest absolute mean difference, which was 0.81 mm in the Frontal and Zygomaticofacial regions, respectively.
The trueness and precision of all four tablet-based applications were clinically acceptable for diagnosis and treatment planning.
The future of the three-dimensional facial scan is auspicious, and it has the potential to be affordable, accurate, and of great value for clinicians in their daily practice.
本研究旨在探究四种基于平板电脑的应用程序（Bellus Dental Pro®[Bellus3D 公司，美国加利福尼亚州坎贝尔]、Capture®：3D Scan Anything[Standard Cyborg 公司，美国加利福尼亚州旧金山]、Heges®[由 Marek Simonik 创立，捷克北摩拉维亚州奥斯特拉瓦]和 Scandy Pro 3D Scanner®[Scandy LLC 公司，美国路易斯安那州新奥尔良]）所获取的数字三维（3D）面部扫描的整体和局部准确性（准确性和精密度）。
用人造模型的面部标记 63 个标志点。随后，在 iPad Pro®（苹果公司，美国加利福尼亚州库比蒂诺）上使用每种扫描应用程序对其进行 5 次扫描。使用 MeshLab®（意大利国家研究委员会-ISTI，意大利托斯卡纳比萨）获取数字测量值，并使用数字游标卡尺（墨西哥城墨西哥城 Granada 殖民地的 Truper Herramientas S.A.）与手动测量值进行比较。计算了各维度差异的绝对平均差值和标准差。此外，还通过单向方差分析、莱文检验和 Bonferroni 校正对数据进行了分析。
Bellus 的绝对平均准确性值为 0.41±0.35mm，Capture 为 0.38±0.37mm，Heges 为 0.39±0.38mm，Scandy 为 0.47±0.44mm。此外，精度值分别为 Bellus 0.46mm、Capture 0.46mm、Heges 0.54mm 和 Scandy 0.64mm。比较各区域发现，Capture 和 Scandy 的绝对平均差异最大，分别为额面和颧骨面区域的 0.81mm。
四种基于平板电脑的应用程序的准确性和精密度均适用于诊断和治疗计划，具有临床意义。
三维面部扫描的前景一片光明，它具有经济实惠、准确且对临床医生日常工作有重大价值的潜力。
