Dv, deviated side; NDv, nondeviated side; SD, standard deviation; UM, maxillary first molar; FHP, Frankfort horizontal plane; ΔNDv−Dv, difference between the NDv and Dv; UC, maxillary canine; LM, mandibular first molar; LC, mandibular canine; -, not applicable.

Values in the same row with no superscript are not statistically significant, and those with different superscript letters (a,b,c) are significantly different at P < 0.05 according to one-way analysis of variance with Tukey’s post-hoc test.

Paired t test was performed to compare the Dv and NDv; ***significant difference at P < 0.001 between the Dv and NDv.
