Figure 4

Illustration of the maxillary and mandibular arches’ lengths as described by Al-Zubair [11]. Anterior palatal length: the vertical distance from the incisal point to the intercanine distance line; molar vertical distance (palatal length): the vertical distance from the incisal point perpendicular to a line between the mesial lingual cusp tips of the first molars; total palatal length: the vertical distance from the incisal point to the midpoint of a line between the distal buccal cusp tips of the second molars; anterior mandibular length: the vertical distance from the incisal point to the intercanine distance line; molar vertical distance (mandibular length): the vertical distance from the incisal point perpendicular to a line between the mesial lingual cusp tips of the first molar; total mandibular length: the vertical distance from the incisal point to the midpoint of a line between the distal buccal cusp tips of the second molar.
