Considerations of maxillomandibular transverse discrepancies in orthodontic treatment
Transverse discrepancy is generally diagnosed upon intraoral examination by the presence of a posterior crossbite.The etiology
of this malocclusion is multifactorial and is associated with hereditary or environmental factors such as skeletal, dental or
congenital abnormalities, nonnutritive sucking habits, mouth breathing, etc. Posterior crossbites remaining into adulthood
could pose a risk for continuous periodontal damage, unstable occlusion and even facial asymmetry. It is not uncommon
to encounter individuals with increased vertical dimensions with relatively narrower upper dental arch and posterior teeth
either compensated or in a crossbite state. In addition, class-2 and 3 patients frequently show transverse dental discrepancies
which further complicate orthodontic treatment. However, most of these clinical findings have been studied by posteroanterior
radiographs which may inevitably include magnification errors because of its 2-dimensional nature. This presentation will show
evaluations of dental arch dimensions and tooth inclinations of the molar area using 3-dimensional CBCT images in adults
with different vertical and sagittal facial types. Vertical dimensions will be categorized as high, normal, low angle based on the
mandibular plane angle and subjects with different sagittal dimensions will be grouped into Class 1, 2 and 3 using the ANB
angle. Appropriate patient cases that show orthodontic treatment in overcoming such transverse discrepancies will be presented
to help correlate the findings of this study for clinical application.
