### Sex Comparison in Habitual Occlusion and Splint Wearing  
The comparison between men and women (Table 1, Figures 1 and 2) showed significant differences in habitual occlusion for the area of the ellipse while standing on the right leg (\(p\geq 0.001\); \(\mathcal{O}\alpha\)\(\vdots\) 695.50 mm\({}^{2}\); \(\mathcal{O}\varsigma\)\(\vdots\) 478.00 mm\({}^{2}\)) and the ROM in cervical extension (\(p\geq 0.001\); \(\mathcal{O}\alpha\)\(\vdots\) 58\({}^{\circ}\); \(\mathcal{O}\varsigma\)\(\vdots\) 62\({}^{\circ}\)). All other parameters of both the balance control and cervical spine movements were not significant.

Table 1: Median, 1 st and 3 rd quartiles of all parameters for men and women. A comparison between men and women in the habitual occlusal position (HO) and the splint (S) condition. Significant \(p\)-values are marked in bold following Bonferroni-Holm correction.  
Apart from the CoP length when standing on the left leg (\(p\leq 0.01\); \(\mathcal{O}\odot\): 366.5 mm\({}^{2}\); \(\mathcal{O}\odot\): 292.0 mm\({}^{2}\)), all other parameters were non-significant in the sex comparison when wearing the splint (Table 1, Figure 3). For the cervical ROM, it can be seen that the male subjects had approximately 74.5 mm more anterior-posterior CoP sway on the left-legged single leg stance than the women.
