CLINICAL FEATURE
change the difference between the twin
siblings’ scans, suggesting a minor role of
the surface morphology on alignment. 19
Therefore, the significant impact of
mirroring may indicate the asymmetry
in the palatal vault. Nevertheless, the
perimeter of the palate determined
by the tooth arch may also impact
symmetry measurement. 21 Overall, the
extent of the discrepancy between
mirrored and non-mirrored counterparts
indicates that if the contralateral
side is available either in the ante- or
postmortem database, the accuracy of
the palatal scan-based identification
process could be challenged or hardly
possible. DA
