“…Several studies have shown that the volume of the nasal cavity increases after rapid maxillary expansion 14 . In addition, the area of the upper airways and nasopharynx increases, 15–18 as does the transverse dimension of the maxillary complex, 14 results that were obtained in the present clinical case.…”

ObjectiveWe report the orthodontic treatment of a class II malocclusion with anterior open bite and posterior crossbite in a patient with Down syndrome (DS) treated with mini‐implants.MethodsTreatment began with rapid maxillary expansion with a Haas appliance, followed by dental alignment and leveling with a fixed appliance and the correction of class II dental relationships with the use of orthodontic mini‐implants associated with a sliding jig.ResultsThe results obtained at the end of the treatment were satisfactory, with improvements in occlusion, including bite closure; maxillary expansion; and the correction of dental relationships.ConclusionWhen well‐planned, orthodontic treatment in a patient with DS achieves satisfactory results from a skeletal, occlusal, and facial perspective.

Introduction. Upper maxillary compression syndrome is characterized by a deficit in transversal development and is recognized within the classification system of the German school. Regardless of the schools’ affiliation according to which this malocclusion is classified, the objective is to determine and select the treatment method with maximum efficiency. Thus, the compression of the upper jaw can also be included as a component in class II subdivision 1 malocclusions, presenting in 2 clinical forms. In addition, the types of palatal suture and their impact on the development of the maxilla in the transverse plane were identified. The purpose of the study was to assess the importance of cone beam computed tomography (CBCT) n providing a comprehensive diagnosis of this malocclusion and formulating an elaborate treatment plan. Material and methods. After applying the inclusion and exclusion criteria, 165 patients were enrolled in the study. The research included patients with jaw compression syndrome diagnosed orthodontically during the mixed and permanent dentition periods. The patients were divided into 3 groups according to the stages of formation of the medio-palatine suture, correlating with their biological age. The research sample was calculated using ANOVA program: fixed effects, omnibus, one-way Analysis. Results. Determining the shape and degree of formation of the median palatal suture at the ages studied in the research, favors the selection of modality, type, and speed of expansion. These factors are directly related to the stage of formation of the palatal suture, which may or may not coincide with the patient’s biological age. CBCT is the method of choice for assessing this. Furthermore, the range of movement in millimeters that can be achieved after separating the upper jaw can be determined, regardless of the type of expansion. Conclusions. Based on the analysis of the data, we can appreciate the variety of expansion methods depending on the degree of formation of the medio-palatine suture. Through a comprehensive paraclinical examination and accurate interpretation, we can establish the definitive diagnosis of this clinical entity and create a treatment plan that minimizes the chance of recurrence.

“…The maturation and density of the midpalatal suture (MS) were assessed by Christovam et al 29 Patients with greater MS density (MSD) had a smaller sagittal area than those with lower density (MSD < 0.75). When compared with stage C, patients in stages D and E MS maturation had a lower sagittal area and intermediate thickness.…”

Objectives: This study used computed tomography (CT) to compare the bone thickness and density values around the zygomaticomaxillary, zygomaticotemporal, and pterygomaxillary sutures that are resistant to rapid maxillary expansion (RME) treatment according to age, sex, and cervical vertebrae maturation (CVM) stage. Methods: The study included 200 paranasal sinus records obtained for medical diagnosis and examination in a radiology clinic. The records provided data on 110 males and 90 females aged between 4 and 28 years. Bone thickness and density values around the zygomaticomaxillary, zygomaticotemporal, and pterygomaxillary sutures were measured using CT imaging. The correlations of bone thickness and density values with the variables of age, sex, and CVM stage were evaluated. Results: No statistically significant difference was revealed between the bone thickness values around the zygomaticomaxillary and zygomaticotemporal sutures and age, sex, CVM stage, and the right and left regions of the same individual (P>0.05). A strong correlation was identified between Hounsfield units (Hu) values on bone density in all 3 regions and age and sex (P<0.001). No correlation was found between the CVM stage and density values around the zygomaticomaxillary, zygomaticotemporal, and pterygomaxillary sutures (P>0.05). Conclusions: The Hu values of the records from females were higher than those of males in all age groups. It was observed that with increasing age, bone density values increased in all 3 regions, and thus circummaxillary region’s Hu value increased.
