Table 1 The measurements of the maxillary dimensions (mm), palate surface (mm2) and volume (mm3) evaluated

From: Assessment of dental arch stability after orthodontic treatment and oral rehabilitation in complete unilateral cleft lip and palate and non-clefts patients using 3D stereophotogrammetry

Linear measurements (mm)

Definition

Inter-canine

C-C′

distance between the cusp tips of the canines.

Intermolar

M-M’

distance between the tips of the mesial-buccal cusps of the first molars.

Arch length

I-M

perpendicular line of the distance between the contact point and the maxillary central incisors up to the intermolar line.

Palate surface

–

Limits standardized: the upper limit was determined by inter-incisor papilla, the lateral limit was surrounded all marginal gingival limits of permanent teeth, and the posterior limit was the midpoint of the distal second molar.

Volume

–

Limits standardized: the upper limit was determined by inter-incisor papilla, the lateral limit was surrounded all marginal gingival limits of permanent teeth, and the posterior limit was the midpoint of the distal second molar.
