摘要

不同环境因素的影响，包括照明，已经被研究过了。然而，环境颜色照明设置对口腔内扫描精度的影响仍然不确定。目的本体外研究的目的是评估环境彩色光照对2台口腔内扫描仪（ios）记录的全弓种植体扫描准确性的影响。材料与方法使用实验室扫描仪（DW-7-140）对6个种植体扫描体的无牙上颌铸型进行数字化处理，获得参考文件。基于所测试的IOS创建两组：TRIOS 4 （IOS-1）和i700 （IOS-2）。根据环境照明颜色（红色、绿色、蓝色、黄色、青色、品红和白色）划分了七个亚组（n=15）。扫描精度采用测量软件（Geomagic Control X）分析，数据分析采用Kruskal-Wallis、单因素方差分析和两两比较（α= 0.05）。结果组间（p < 0.05）和亚组间（p < 0.05）的准确率和精密度均有显著性差异。对于IOS-1，蓝色环境光获得了最好的真实度（19.8±1.8µm）（P< 0.05）；在精度上，白光（20.8±7.3µm）和蓝光（22.1±13.5µm）效果最好（P< 0.05）。对于IOS-2，白光的真实度最高（51.9±16.7µm）；在品红光（38.6±10.4µm）和黄光（52.6±24.0µm）下获得最佳精度（P< 0.05）。结论不同评估的ios的最佳环境色照明存在差异。由于没有找到最大化精度的最佳条件，因此必须针对所使用的IOS系统个性化环境色照明。

Influence of the ambient color lighting on the accuracy of complete arch implant scans recorded by using two intraoral scanners

Statement of problem

The influence of different ambient factors including lighting has been previously studied. However, the influence of ambient color lighting settings on intraoral scanning accuracy remains uncertain.

Purpose

The purpose of this in vitro study was to assess the influence of ambient color lighting on the accuracy of complete arch implant scans recorded by using 2 intraoral scanners (IOSs).

Material and methods

An edentulous maxillary cast with 6 implant scan bodies was digitized by using a laboratory scanner (DW-7–140) to obtain a reference file. Two groups were created based on the IOS tested: TRIOS 4 (IOS-1) and i700 (IOS-2). Seven subgroups were developed depending on the ambient color lighting (red, green, blue, yellow, cyan, magenta, and white) (n=15). Scanning accuracy was analyzed by using a metrology software program (Geomagic Control X). The Kruskal-Wallis, 1-way ANOVA, and pairwise comparisons were used to analyze the data (α=.05).

Results

Significant trueness and precision values were found across the groups (P<.05) and subgroups (P<.05). For IOS-1, blue ambient lighting obtained the best trueness (19.8 ±1.8 µm) (P<.05); in precision, white light (20.8 ±7.3 µm) and blue light (22.1 ±13.5) showed the best results (P<.05). For IOS-2, white light showed the best trueness (51.9 ±16.7 µm); the best precision was obtained under magenta (38.6 ±10.4 µm) and yellow light (52.6 ±24.0 µm) (P<.05).

Conclusions

The optimal ambient color lighting varied between the IOSs assessed. As the best condition for maximizing accuracy was not found, ambient color lighting must be individualized for the IOS system used.
