“…Significantly decreased nasopharyngeal volumes were reported using computed tomography (CT) in patients presenting mandibular retrusion when compared to the ones presenting mandibular prognathism [8] and also if compared to control group without retrognathism [9]. On the contrary, significantly higher oropharyngeal volume was reported in Class III malocclusion patients when compared to Class I patients [10].…”

Role of mandibular displacement and airway size in improving breathing after rapid maxillary expansion

BackgroundOral breathing and maxillary deficiency are often associated with steep mandibular plane angle, and retrognathic mandible compared with the faces of healthy controls. Some studies suggested that after rapid maxillary expansion, improvement in nasal breathing and repositioning of mandible with transitory increasing of facial height and, in some cases, spontaneous forward repositioning might occur. The abovementioned mandibular effects could contribute to enlarge oropharynx volume with repositioning of tongue and soft palate with an improvement of upper airway volume after treatment. The aim of this study was to investigate by cone beam computed tomography the role of oropharyngeal volume and mandibular position changes after rapid maxillary expansion in patients showing improved breathing pattern confirmed by polysomnography exam.MethodsThe final sample of this retrospective study comprised 14 Caucasian patients (mean age 7.6 years) who undergone rapid maxillary expansion with Haas-type expander banded on second deciduous upper molars. Cone beam computed tomography scans and polysomnography exams were collected before placing the appliance (T0) and after 12 months (T1). Mandibular landmarks localization and airway semiautomatic segmentation on cone beam computed tomography scans allowed airway volume computing and measurements.ResultsNo significant differences were found between oropharyngeal airway changes and mandibular displacement after rapid maxillary expansion in growing patients.ConclusionsThe suggested improvement in upper airway and breathing after rapid maxillary expansion should be further related to different compartments of airway such as rhinopharynx and nasal cavity.

What are the key considerations for the interdisciplinary dentofacial therapy (IDT) team in the diagnostic process to evaluate a patient for surgically facilitated orthodontic therapy (SFOT)? Summary: SFOT creates a demineralized bone matrix and augments dentoalveolar deficiencies in the management of dentofacial disharmony malocclusion. Numerous indications and contraindications exist which are essential to the periodontal surgeon for proper case selection. A collaboratively focused workup by an IDT team is equally essential. Cone beam computed tomography (CBCT) and orthodontic simulation software which identifies changes in the dentoalveolar complex influenced by tooth movement are critical in providing transparency to the patient and IDT team during the treatment planning process. Such transparency can aid the team in assessing goals and outcomes that consider and respect foundational dentoalveolar parameters while contributing to sustainable outcomes. Conclusions: The SFOT IDT decision making process is complex, yet full of opportunities. Embracing SFOT IDT with innovative and novel 3D technology can optimize conditions leading to long-term outcomes that align with periodontal stability as well as patient goals and preferences which permeate beyond the achievement of "straightening teeth". Transparency of complex IDT through 3D CBCT and orthodontic simulation software engenders "collaborative accountability" and can improve patient communication which is critical to developing meaningful and essential treatment plans.
