A, CBCT transversal dimensions in the molar region; B, maxillary permanent first molar inclination. NCW, Nasal cavity width: width of the nasal cavity measured at the level of the intersection between the nasal cavity and the maxillary sinus floor; when the right and left intersections were not leveled, and only the right side was used as the reference for a measurement parallel to the horizontal plane. MxW, Maxillary width: maxillary width at the level of the hard palate. CW, Cleft width was measured from the right cleft border to the left cleft border parallel to the horizontal plane. ACW, Alveolar crest width: maxillary width at the level of the interpalatal alveolar crest. AW, Arch width: dental arch width measured at the level of the palatal cusp points. I, Tooth Inclination: the angle between lines passing through the buccal and lingual cusp tips of the first molars.
