Table 2 Description of the measurements and intrarater reliability

Measurement	Description	ICC
Wits T1 [mm]	Distance between perpendicular projections of points A and B on the occlusal plane	0.973
SPP-OP T1 [°]	The angle between occlusal plane and spina palatal plane	0.989
ANB T1 [°]	The ANB angle measures the anteroposterior relationship between the maxilla and the mandible	0.973
Interincisal angle T1 [°]	The angle between a line through long axis of lower incisor and a line through long axis of upper incisor	0.993
Lower 1/GoMe T1 [°]	The angle between a line through long axis of lower incisor and the mandibular plane	0.994
Lower 1 displacement [mm]	Displacement of the center of resistance of the lower incisor in the structural superposition of the mandible at T1 and T2	0.923

ICC < 0.5: poor reliability; 0.5 ≤ ICC < 0.75: moderate reliability; 0.75 ≤ ICC < 0.9: good reliability; ICC ≥ 0.9: excellent reliability
