Table 1.
Descriptive statistics of the studied parameters in the two study groups and significance levels from the hypothesis tests. GCD, global coronal deviation; Cx, Cy, Cz, vectoral components of GCD; HCD, horizontal coronal deviation; GAD, global apical deviation; Ax, Ay, Az, vectoral components of GAD; HAD, horizontal apical deviation; AD, angular deviation; τ, torque; t, time. *Az = vertical deviation (VD)
