Measurement methods of variable factors.

Factor variables	Measurement methods
	Distance between a point on each side of the midpalatal suture corresponding to the bilateral cuspids
	Width across the buccal cusp of the right and left first premolar
	Distance between a point on each side of the midpalatal suture corresponding to the bilateral maxillary first molars
	Maximum width of the nasal part at the first maxillary molar level on both sides
	Distance between the lowest points of the alveolar bone on the buccal side of the first maxillary molar level, bilaterally
	Distance between the points of the palatal roots on each side of the first maxillary molar level, bilaterally
	Distance between the points of the buccal cusps on both sides at the first maxillary molar level bilaterally
	Medial angle between the line of the buccal cusp of the right molar and the cusp of the palatal root and the palatal plane
	Medial angle between the line of the buccal cusp of the left molar and the cusp of the palatal root and the palatal plane
	The angle between the extension of the line between the buccal cusp of the right molar and the tip of the palatal root and the extension of the line between the buccal cusp of the left molar and the tip of the palatal root
