's [14] studies on 3D models for malocclusion evaluation suggest that there is variability in maxillary arch variations among different malocclusion groups. The authors used the values from the ICD-intercanine distance and IM-intermidar distances, and for the measurements of palatal height, they used the length of the perpendicular line from the deepest point on the palate on the mid palatal raphe joining a straight line from the deepest portion of gingival contours of teeth 16 and 26 in [PERSON] et al. study [14]. Last but not least, [PERSON] et al. 's 2019 study compared dental malocclusion and palatal dimensions in correlation with fingerprint dermatoglyphics [14]. On the other hand, upper incisors and upper anterior teeth also are valuable for study purposes [19; 20]. [PERSON]'s [19] study indicated that the angle of circumferences of upper anterior teeth of the narrow, short, and deep palates will be more tapered than that of the wide, long, and shallow palates. With this conclusion from the study, it seems that vertical and horizontal dimensions, along with palate depth, are essential for teeth's position in the bone. On the other hand, [PERSON] et al. 's [20] study estimated that the height and shape of central maxillary incisors vary in men and women along with occlusion type and are greatly related to anterior facial height. Similar results had been seen in the authors' study; however, the data on gender and palatal dimensions on stereolithographic models were not conclusive enough. Since the shape and volume in all stereolithographic models vary in statistical analysis, it seems that anterior maxillary dimensions are more asymmetrical than posterior ones, which might correspond with the time of teeth loss and therefore bone remodeling. Therefore, 3D stereolithographic models should be used for planning and evaluation purposes rather than gender classification. However, if a bigger test group would be evaluated, perhaps then a statistically significant result on palatal: gender values can be concluded. Patients undergoing orthodontics treatment also require 3D jaw evaluation, mostly to establish the type of malocclusion. In edentulous patients, the shape and size of alveolar bone are shaped by the movement of teeth during orthodontic treatment. A significant correlation between torque variations and bone thickness changes was observed for the apical buccal level of the anterior side [21] (\(p<0.05\)). According to [PERSON] et al., limited and not significant alveolar bone resorption for the apical thickness of anterior teeth occurred at \(\pm 5\) degrees of torque variation, while for tooth inclination exceeding +5 or \(-5\) degrees, the bone remodeling was more evident [21]. This result was more visible in the anterior region, which had been the most affected area by bone remodeling and that torque variation was highly related to apical bone thickness adaptation for maxillary and mandibular incisors and maxillary canines [22]. Also, orthognathic surgery and surgically assisted maxillary surgery SARME impact palatal dimensions. In this study, three-dimensional palatal measurements, including depth, length, and width, were measured in an attempt to discover their correlation with each maxillary arch form and perimeter based on six measurement proportions, which in theory should be more asymmetrical in the anterior region due to the SARME procedure surgically enhancing bone formation between anterior incisors. It seems that measurements of inter-molar width, inter-canine width, and arch perimeter are evaluated quite a lot [21; 22]. The mentioned authors concluded, that about two-thirds of those seeking orthodontic treatment were females. Nearly 80% of the tested sample had a narrow palate, followed by 15 and 5% with an intermediate palate and broad palate, respectively.
