Figure 2 The three sagittal dimensions used to measure the size and position of the rugal zone: a–b = incisive papilla (IP) to the anterior-most point; a–c = IP to the last primary or secondary ruga; a–d = IP to the posterior border of the last ruga.

Figure 3 The four coronal dimensions of the dental arch and palate: a–b = mesiopalatal cusp of first permanent molar or second primary molar to mesiopalatal cusp of first permanent molar or second primary molar; a–c and b–c = mesiopalatal cusp of first permanent molar or second primary molar to median palatal raphae in relation to first permanent molar or second primary molar; d–c = the perpendicular distance.
