Palatal volume and area assessment on digital casts generated from cone-beam computed tomography scans

Abstract: Objectives: The objective of this study was to develop a reproducible method to measure the change of palatal volume and area through superimposition using maxillary expansion digital cast models. Materials and Methods: A total of 10 pre-and 10 postexpansion dental cast models were scanned by the same cone-beam computed tomography machine. Superimposition was performed using a fully automated surface-best fit of the palatal surfaces on the digital cast models. A gingival plane, identified only once on superimp… Show more

“…The first attempt to measure palatal volume was made by Heiser et al in 2004 where the volume was measured indirectly by weight correlation . The palatal volume assessment has been done on digital study cast using 3D software programs in mouth breathing subjects, obstructive sleep apnoea patients, skeletal Class III and crossbite subjects. Recently, only one study has been done on palatal volume assessment in UCLP (Table ).…”

“…With the introduction of 3D imaging tools such as dental cone-beam computed tomography (CBCT), most limitations in 2D imaging have been theoretically overcome [2]. Many research groups have been developing 3D analysis based on CBCT superimposition to analyze treatment and/or growth changes [37]. Currently, two main methods developed by two different research groups are used to superimpose CBCT images.…”

“…In last years, some studies evaluated clinical reliability and validity of the 3D measurements of features such as the palatal volume, occlusal relation, arch height, overjet and overbite, which are difficult to measure accurately using a Vernier caliper and stone models in MSD or CBCT digital model [ 35 ]. A study of the validity of 3D measurements in ISD would also be helpful.…”
