“…Controversy still exists concerning the accuracy of the lateral cephalograms since they depict a two‐dimensional view of a three‐dimensional structure . However, we chose this method instead of cone‐beam computed tomography scans for ethical reasons and because the potential benefits of diagnosis and treatment planning do not outweigh the potential risks of an increased radiation dose …”

Structured Abstract Introduction Planning successful treatment for the correction of anatomic abnormalities of the upper airways, by surgical advancement of the mandible, depends on extensive knowledge of the pharyngeal airway space (PAS). However, there is limited scientific evidence about changes in PAS after mandibular advancement surgery. Aim To evaluate the immediate changes in superior posterior airway space (SPAS) in Class II patients, after mandibular advancement surgery. Materials and Methods A cephalometric evaluation of 37 patients with skeletal Class II deformity was performed at 2 distinct time intervals: Pre‐operative (T0) and immediate post‐operative (T1), using Dolphin Image & Management Solutions, version 11.9, according to the method of Arnett/Gunson FAB Surgery. The differences due to the surgical intervention were assessed with Student's t test, and a Principal Component Analysis was used to evaluate the relationship between mandibular advancement and SPAS variables. Anticlockwise and clockwise rotation groups were also evaluated with Mann‐Whitney tests. The statistical analysis was conducted in SPSS and R assuming a 0.05 level of significance. Results As an effect of mandibular advancement, an anteroposterior statistically significant increase in SPAS (P < 0.001) was perceived at all points measured. Conclusion Our findings indicate that mandibular advancement surgery is a viable option to achieve widening of the SPAS in patients with Class II skeletal morphology.

Aim: The aim of this study was to evaluate, through cone beam computed tomography (CBCT), the transverse dimension of the alveolar bone in the posterior region of the maxilla and mandible in subjects with different patterns of mastication, comparing both sides of the arches according to the performance of the masticatory function. Methods: 39 subjects not orthodontically treated, with normal occlusion or symmetrical malocclusion, and normal periodontal condition were selected. Twenty-one subjects (54%) were identified as having preferential unilateral mastication, 11 subjects (28%) had bilateral mastication and 7 (18%) had exclusive unilateral mastication. All participants were submitted to CBCT and the buccolingual dimension of the posterior regions was evaluated at a height of 2, 4, 6, 8, and 10mm from the alveolar crest. Results and Conclusion: Subjects with bilateral mastication showed statistically significant difference between the right and left sides at the heights of 6 (p=0.030) and 8mm (p=0.023) between the first and second maxillary premolars. There was no difference in the transverse dimension of the alveolar bone in the posterior regions of maxilla and mandible between preferred and non-preferred sides in subjects with preferred unilateral mastication and between right and left sides in subjects with bilateral mastication.

“…Superimposition of a patient's 2D cephalograms is traditionally indicated whenever evaluation of orthodontic treatment and/or growth is needed. More recently, superimposing the 3D digital models or CBCT images makes it possible to assess these changes in a 3D manner . A recently developed software (Ortho Mechanics Sequential Analyzer OMSA) was introduced to enable visualization and superimposition of digital dental models .…”

Structured Abstract Objective To assess validity and reliability of palatal superimposition of holograms of 3D digital dental models using a customized software, (Ortho Mechanics Sequential Analyzer OMSA), installed on Microsoft HoloLens device as compared to the OMSA application running on a regular computer screen. Methods The sample consisted of pre‐ and post‐treatment digital maxillary dental models of 20 orthodontic cases (12.3 ± 1.9 years) treated by rapid maxillary expansion (two turns per day). For each case, the pre‐ and post‐treatment digital models were superimposed using hand gestures for marking the dental models holograms in mixed reality using the Microsoft HoloLens. The same models were then superimposed using the conventional landmark‐based method with OMSA software running on a regular computer screen. The same set of dental arch parameters was measured on the superimposed 3D data by the two software versions for comparison. Agreement in the superimposition outcomes among the two superimposition methods was assessed using Dahlberg error (DE), concordance correlation coefficients (CCCs) using two‐way ANOVA mixed model for absolute agreement and Bland‐Altman analysis. Results Repeatability was acceptable for all variables based on the high values of CCCs over 0.99 with a lower 95% confidence limit over 0.95 for any variable. The DE ranged from 0.14 mm to 0.36 mm. The absolute error did not exceed 0.5 mm for any variable. Conclusion Using the depth vision capabilities of the Microsoft HoloLens, 3D digital dental models can be reliably superimposed allowing virtual assessment of orthodontic treatment outcomes.
