“…Furthermore, a few recent CBCT studies have shown three-dimensional asymmetrical alterations of the temporomandibular joints in unilateral posterior crossbite patients [ 10 , 36 , 37 , 38 , 39 , 40 ]. Even though these studies are very interesting, because they provide a more direct confirmation of the morphological alterations of mandibular condyles in unilateral posterior crossbite patients, the routine use of CBCT imaging on children should be viewed with caution.…”

“…However, a large number of studies have shown that the skull is not perfectly symmetrical, and this method can not be applied to cross the midline, and bilateral defects. [10][11][12][13][14][15] Another commonly used method is the SSM. 16 Its primary method is to obtain a set of bone shapes from the face of normal people and then use principal component analysis (PCA) to construct SSM for these shapes.…”

“…One of the most classic is the mirror technique, 9 whose primary method is to find the median sagittal plane and map the normal skull to the defective skull. However, a large number of studies have shown that the skull is not perfectly symmetrical, and this method can not be applied to cross the midline, and bilateral defects 10–15 . Another commonly used method is the SSM 16 .…”

“…Besides, the use of 3D FE models from CT or CBCT images is limited during childhood due to the low grey gradient between unmineralized structures at these ages. This fact makes difficult the segmentation procedure, requiring intensive manual work (Ort un-Terrazas et al 2020). As an alternative, panoramic radiographs or 2D-cephalograms in frontal, lateral, and submentovertex views are currently used to evaluate the morphological differences between both joints during childhood.…”
