  1. Note Values are presented as medians (upper and lower quartiles);
  2. *Statistically significant difference was evaluated by the Wilcoxon signed-rank test, with a significance level of P < 0.05
  3. RCX/LCX: The right/left condyle maximum sagittal anteroposterior displacement on the X-axis. RCY/LCY: The right/left condyle maximum left-right displacement on the Y-axis. RCZ/LCZ: The right/left condyle maximum superoinferior displacement on the Z-axis. RCSCI: The right condylar inclination in the sagittal plane when the displacement is 5 mm. LCSCI: The left condylar inclination in the sagittal plane when the displacement is 5 mm. RCTCI: The right condylar inclination in the transverse plane when the displacement is 5 mm. LCTCI: The left condylar inclination in the transverse plane when the displacement is 5 mm
