Figure 4

3D-fitting comparison of digital impression files ((a) SHINING, (b) CEREC, and (c) TRIOS) with gold standard file. Within the specified accuracy range, green represents the overlap between test groups and control group, yellow represents higher than the control group, and blue represents lower than the control group. The greener areas mean the more accurate the scanned image.
