“…The present study found no difference when the sides were compared, corroborating the study by Kang et al 23 A statistically significant difference occurred between genders, with a lower mean in women (1.97 to 11.83 mm) and a higher mean in men (2.08 to 14.26 mm), thus showing a greater bone thickness in males than in females for most measurements performed, in agreement with the study by Ning et al 30 This significant difference found between men and women can be explained by sexual dimorphism affecting the hard palate, as men tend to have denser and larger bones than women 31 …”

Rapid palatal expansion (RPE) with expanders such as the Hass and Hyrax devices is used for the treatment of patients with transverse maxillary deficiency. 1,2 The side effects caused by these devices become more common as skeletal expansion decreases and include bone dehiscence or fenestration, gingival recession, root resorption, buccal tipping of the posterior teeth and post-treatment relapse. 3,4 The MARPE (microimplant-assisted rapid palatal expansion) technique is a modification of the rapid palatal expansion method, whose main difference is the insertion of mini-implants adjacent to the midpalatal suture to ensure greater bone expansion and less tooth movement. 5 Studies have observed that an average of 10% of

“…The aforementioned issue is referred to just to provide a better understanding, but the focus of this study was the influence of software, and there is no intention to draw attention to the findings of previous studies. [33][34][35] Since the group without an open bite had smaller dimensions according to both software packages, and given the intentional use of a higher threshold for the NemoStudio software, as well as the relationship of this threshold with the algorithm configuration, the values obtained with Ne-moStudio were higher, leading to significant differences in the measurements for the non-open bite group.…”

Background. Using different software to evaluate the airways, with different thresholds, but within the range for airway recognition, could yield different measurements in the same patient with or without craniofacial disharmony. Objectives.The aim of the present study was to compare the volume and the most constricted area (MCA) of the oropharynx in individuals with or without an open bite by using 2 software programs meant for cone-beam computed tomography (CBCT).Material and methods. This comparative study included 60 cases selected from 137 CBCT scans obtained from individuals with the presence or absence of an open bite. Each group included adults of both genders -in total 30 women and 30 men -with a mean age of 27.57 ±11.85 years in the open bite group and 26.23 ±6.78 years in the control group. The oropharyngeal volume and MCA were measured with 2 three-dimensional (3D) software packages: Planmeca Romexis ® ; and Nemotec NemoStudio ® . Two calibrated orthodontists trained in the use of the software made the measurements. Data was analyzed using Student's t tests for independent and paired samples (p < 0.05). Results.In general, the oropharynx volume measurements obtained with the NemoStudio software were significantly higher than those obtained with Romexis (19,007.17 ±8005.79 mm 3 and 17,823.47 ±7148.62 mm 3 , respectively) (p = 0.020). However, when the groups were analyzed separately, the measurements of the group with an open bite did not differ according to the software used (p = 0.352). The measurements of the MCA of the oropharynx were significantly higher when obtained with the NemoStudio software (MD (mean difference) = 19.02 mm 2 ) (p = 0.005). In contrast, no difference in the MCA results for the 2 software packages was found in the open bite group (p = 0.728).Conclusions. The volumetric and cross-sectional measurements of the oropharyngeal airway, particularly in individuals without an open bite, were affected by the software used.

“…Furthermore, subjects with Skeletal Class II had a smaller MWC than those with Skeletal Class I in this study. Previous studies had reported that the maxillary width was smaller in subjects with Skeletal Class II than in those with Skeletal Class I [ 21 ]. Nasal obstruction, a low tongue position, abnormal swallowing, and sucking habits contribute to a reduction in maxillary width in individuals with Skeletal Class II [ 41 ].…”

“…Although some research attempted to analyze airways in people with different sagittal relationships using three-dimensional (3D) evaluation, these studies primarily focused on individuals with nasal breathing (NB) pattern [ 7 , 9 , 19 , 21 ]. The relationship between pharyngeal airway and skeletal malocclusion in mouth breathing subjects was not extensively studied in previous literature.…”

Objective This study aimed to investigate whether the subjects with mouth breathing (MB) or nasal breathing (NB) with different sagittal skeletal patterns showed different maxillary arch and pharyngeal airway characteristics. Methods Cone-beam computed tomography scans from 70 children aged 10 to 12 years with sagittal skeletal Classes I and II were used to measure the pharyngeal airway, maxillary width, palatal area, and height. The independent t-test and the Mann–Whitney U test were used for the intragroup analysis of pharyngeal airway and maxillary arch parameters. Results In the Skeletal Class I group, nasopharyngeal airway volume (P < 0.01), oropharyngeal airway volume (OPV), and total pharyngeal airway volume (TPV) (all P < 0.001) were significantly greater in subjects with NB than in those with MB. Furthermore, intermolar width, maxillary width at the molars, intercanine width, maxillary width at the canines, and palatal area were significantly larger in subjects with NB than in those with MB (all P < 0.001). In the Skeletal Class II group, OPV, TPV (both P < 0.05) were significantly greater in subjects with NB than in those with MB. No significant differences in pharyngeal airway parameters in the MB group between subjects with Skeletal Class I and those with Skeletal Class II. Conclusion Regardless of sagittal Skeletal Class I or II, the pharyngeal airway and maxillary arch in children with MB differ from those with NB. However, the pharyngeal airway was not significantly different between Skeletal Class I and II in children with MB.
