“…Transverse dimensions can also be measured using dental casts, such as dental arch width, which is measured from the cusp tips, and basal arch width, which is measured as the distance between the points at the mucogingival junction adjacent to the respective cusp tips [35]. There is a high chance that dentoalveolar compensations may mask the underlying transverse deficiency while making use of these methods.…”

A new era in 3-dimensional analysis has begun with the use of cone-beam computed tomography (CBCT) in orthodontics, which promises to provide a more thorough understanding of the craniofacial skeletal architecture. This study aimed to investigate the correlation between the transverse basal arches discrepancy and dental compensation by utilizing CBCT width analysis. An observational study was conducted to retrospectively review 88 CBCT scans of patients presented to dental clinics from 2014 to 2020 obtained from the Planmeca Romexis x-ray system at three centers. Dental compensation data across normal and narrow maxillae were analyzed and a Pearson correlation was used to find the relationship between molar inclination and width difference. Significant maxillary molar compensation differences were observed between the normal maxilla and narrow maxilla group, where the amount of dental compensation (164.73 ± 10.15) was higher in the narrow maxilla group. A significant negative correlation (r = −0.37) was observed between width difference and maxillary molar inclination. Maxillary molars were tipped buccally to compensate for the reduced maxillary arch width. These findings are important to determine the amount of needed maxillary expansion taking into account the buccal inclination while treating cases.

“…The 3D CBCT has been considered the gold standard to examine the transverse skeletal and dental dimension with high sensitivity and specificity [ 24 , 46 ]. The landmarks and analysis methods used in our study have been tested or slightly modified from the previous publications, demonstrating a high degree of reproducibility, and confirming the statistical suitability of the methods [ 12 , 15 , 32 , 47 , 48 , 49 , 50 , 51 , 52 ].…”

The aim of this study is to evaluate the longitudinal transverse growth of the maxillo-mandibular complex in untreated children using the Cone Beam Computed Tomography (CBCT). Two sets of scans on 12 males (mean 8.75 years at T1 and 11.52 years at T2) and 18 females (mean 9.09 years at T1 and 10.80 years at T2) were analyzed using Dolphin 3D imaging. The transverse widths of various maxillary and mandibular skeletal landmarks and the dentoalveolar and dental landmarks at the level of first molars were measured. Overall, there were greater increases in the transverse dimension in the posterior than anterior portions of the maxilla and mandible. The increase in intergonial width of the mandible seems to be primarily due to the lengthening of the mandibular body. The dentoalveolar process at the first molar level increases at an equal rate corono-apically and is independent to the changes in molar inclination. When comparing maxillary dentoalveolar changes with that of the mandible, greater increases were noticed in the maxilla, which might be explained by the presence of sutural growth in the maxilla. Moreover, the first molars maintain their coordination with each other despite the differential increase in the maxillary and mandibular dentoalveolar processes.

El diagnóstico ortodóncico en la última década se ha potenciado con los avances tecnológicos, dejando de lado los métodos tradicionales de diagnóstico, como lo son el análisis de modelos, sobre todo cuando se trata del análisis transversal. Este trabajo busca brindar al clínico una opción sencilla en el diagnóstico del problema transversal, a través de modelos de yeso. Para sustentar esta propuesta se recolectaron datos de siete pacientes que fueron diagnosticados con compresión maxilar esqueletal, en edades comprendidas entre 10 y 14 años. Se tomaron datos de modelos de estudio en yeso extraduro, así como CBCT antes y después del tratamiento con MARPE. El análisis de UPenn se utilizó en la CBCT y el análisis de modelos se realizó midiendo desde el punto dentogingival derecho al izquierdo de los primeros molares permanentes superiores e inferiores, utilizando un calibrador Mitutoyo de 0.05mm de exactitud. Se realizó la comparación de promedios de ambas medidas la cual demostró que no hay diferencia significativa y luego se hizo la correlación de medidas que demostró ser significativa en 5 de 7 medidas. Esta propuesta de análisis de modelos (AN-BAR) puede ser útil para el clínico en la toma de decisión al momento de realizar una expansión maxilar.
