“…Heiser et al [7] assessed the three-dimensional dental arch and palatal form changes after extraction and nonextraction treatment and concluded that there was no much difference in the palatal forms of both the extraction and nonextraction groups. The palatal form both vertically and sagittally showed different reactions to orthodontic treatment with premolar extraction compared to the nonextraction group from pretreatment to follow-up.…”

“…Compared to the extraction group, the stability of palatal form was more in nonextraction group. [7] A study was conducted by Bishara et al [8] for assessing the dental arch changes in patients with Class-II division 1 malocclusion with extraction and nonextraction treatments. The results of our study could not be compared although the intermolar changes were similar to their study.…”

Superimposition of serial cephalometric radiographs has been widely used to evaluate orthodontic tooth movement. [1] A cephalometric radiograph is a two-dimensional projection of three-dimensional structures, which has certain limitations such as blurring, overlapping of anatomic structures, and magnification. Superimposition of serial cephalometric radiographs uses skeletal structures such as cranial base, maxilla, or mandible as reference points or lines. On the other hand, superimposition of dental casts has inherent limitations due to lack of anatomic reference points or areas for superimposition. Some authors evaluated the stability of the palatal rugae during orthodontic treatment. [2][3][4] Husain [5] used a flatbed scanner for imaging the plaster models, and this method can be used for scanning multiple sets of models simultaneously. [5] The medial points of the third palatal rugae and palatal vault were suggested to be the most stable and suitable reference points for the assessment of anteroposterior tooth movement. [1] Palate, due to its morphology and position, is one of the key anatomic structures in determining the type of skeletal pattern, and most importantly, the palate can be influenced by orthodontic treatment procedures.

“…These methods are fast and sufficiently simple for clinical applications, and they allow creation of databases for several subsequent quantitative evaluations. [18][19][20] In the present study, the size and shape of the hard palate of Italian subjects with hypohidrotic ectodermal dysplasia were analyzed using a computerized 3D electromagnetic instrument that provides the spatial coordinates of actual landmarks directly digitized on dental stone casts. 18,19 Data were used in mathematical and geometrical models to distinguish the effect of size from that of shape on palatal features as compared with reference measures collected on healthy subjects of the same age, sex, and ethnicity.…”

“…These include laser scanning, stereophotogrammetry, optical electronic systems, electromagnetic digitizers, and 3D digital computer-aided procedures. [5][6][7][8][9][10] Oral parafunctions or harmful habits can affect normal palatal growth. Breathing, sucking, mastication, swallowing, and sound pronunciation are part of the neuromuscular functional system.…”

Objective: To measure palatal landmarks of healthy nonpatient children aged 3 to 6 years with a normal deciduous dentition and to evaluate palatal shape independent of size. Materials and Methods: Fifty-eight dental casts of children with a normal and complete deciduous dentition were obtained and digitized with a computerized 3D instrument. At all ages, male and female data did not differ (Student's t-test), so the pooled values were considered. Dimensions were compared between ages by analyses of variance. Results: Palatal slope and height increased significantly as a function of age (P Ͻ .001). Palatal length did not change with age (average: 23.1 mm). In the frontal plane, the intermolar width increased slightly with age by about 1.8 mm at the second molars, 1.1 mm at the first molars, and 0.9 mm at the canines. Palatal height in the frontal plane did not change in the posterior part of the palate, but decreased anteriorly. The intercanine distance increased by 0.9 mm with age. However, this change did not reach statistical significance. Conclusions: Between 3 and 6 years of age, palatal shape changed and became proportionally higher in both the frontal and sagittal planes.
