dc.description.abstractIntroduction: This study aimed to evaluate the stability of palatal rugae patterns after slow maxillary expansion (SME) treatment and the reliability of the rugae region as a reference region in digital superimposition. Methods: The SME group comprised 21 subjects with Angle Class I or Class II dental malocclusion with unilateral or bilateral crossbite and constricted maxilla and were selected before the pubertal peak. Intraoral scans were captured via the intraoral scanner iTero Element software (version 1.13; Align Technology, San Jose, Calif) before treatment and after completion of 12 rotations of the screw in the expansion appliance. Patients rotated the screw once a week by the established protocol. The digital data of the impressions were analyzed using GOM Inspect 3D analysis software (version 2018; GOM GmbH, Braunschweig, Germany). Dimensional changes in rugae after SME were measured with MeshLab software (version 2022.02, the Visual Computing Lab of CNR-ISTI, Italy). For the statistical analysis, the Shapiro-Wilk test was used to assess normality, whereas the Kruskal-Wallis and Mann-Whitney U tests were applied for group comparisons. Results: According to digital superimposition data, the root mean square value of the rugae region in the SME group was found to be 0.195 ± 0.086 mm. The greatest dimensional change was found in the third rugae (1.70 ± 0.42 mm, P <0.001). Post-hoc pairwise comparisons revealed a statistically significant difference between the dimensional changes of the first and third rugae (P <0.05). No statistically significant difference was found as a result of pairwise comparisons of the right and left rugae points (P = 0.083 and P = 0.200, respectively). Conclusions: The observed transverse dimensional changes in the rugae, particularly in the third rugae, indicate that caution should be exercised in using the rugae region as a reference in superpositions after SME treatment. © 2024 American Association of Orthodontists
