“…Ultimately, after undergoing a comprehensive assessment based on the predetermined inclusion criteria, a total of 7 articles were deemed eligible and subsequently included in the final analysis [9,11,[14][15][16][17][18]. The other 19 articles were excluded due to the following reasons: nine lacked maxillary cephalometric measurements [8,13,[20][21][22][23][24][25][26]; three were focused on nonsurgical RPE [27][28][29]; three included patients with orthodontic tooth movement between the two time points of obtaining radiological images [10,30,31]; two were systematic reviews [32,33]; one was reported again in a later study by the same team [34]; and one was a case series with limited sample size [35]. The PRISMA flowchart of the article inclusion and exclusion screening is shown in Figure 1.…”

Surgically assisted rapid palatal expansion (SARPE) is often performed to correct the transverse deficiency in the maxilla for skeletally mature patients. However, there is little consensus on the sagittal and vertical displacement of the maxilla after SARPE. This systematic review aims to analyze the position changes of the maxilla in the sagittal and vertical dimensions after the completion of SARPE. Registered with PROSPERO (registration number: CRD42022312103), this study complied with the 2020 PRISMA guideline and was conducted on 21 January 2023. Original studies were screened from MEDLINE (PubMed), Elsevier (SCOPUS), and Cochrane, and supplemented by hand-searching. Cephalometric changes of skeletal vertical and sagittal measurements were the focus. A fixed-effects model was applied in R for meta-analysis. After applying inclusion and exclusion criteria, seven articles were included in the final review. Four studies had a high risk of bias, and the other three had a medium risk of bias. Meta-analysis revealed that the SNA angle increased by 0.50° ± 0.08° (95% confidence interval, 0.33° to 0.66°), and the SN–PP angle increased by 0.60° ± 0.09° (95% confidence interval, 0.41° to 0.79°) after SARPE. In summary, the maxilla displayed statistically significant forward and clockwise downward movement after SARPE. However, the amounts were small and might not be clinically significant. Due to the high risk of bias of included studies, our results must be taken cautiously. Future studies are needed to discern the effects of direction and angulation of the osteotomies of SARPE on the displacement of the maxilla.

“…GMM is the statistical analysis of shape and size features, including pathologies, as they describe configurations of landmark points in two or three dimensions. Well established in anthropology (Weber & Bookstein, ) and paleobiology (Lawing & Polly, ), this method is increasingly being used in fields of medical research such as orthodontics (Bertl et al, ; Celar, Freudenthaler, Celar, Jonke, & Schneider, ), anatomy (Loth et al, ), psychology (Prasad et al, ), and craniofacial surgery (Segna et al, ; Trefný, Krajíček, & Velemínská, ). In earlier applications to mouse models, GMM has led to discoveries in ontogenetic development (Boughner et al, ), quantitative trait locus effects (Workman, Leamy, Routman, & Cheverud, ), relationships between gene and pathology (Green et al, ) and similarity of developmental processes to those of humans (Martínez‐Abadías et al, ).…”

Sclerosteosis, a rare autosomal recessive genetic disorder caused by a mutation of the Sost gene, manifests in the facial skeleton by gigantism, facial distortion, mandibular prognathism, cranial nerve palsy, and, in extreme cases, compression of the medulla oblongata. Mice lacking sclerostin reflect some symptoms of sclerosteosis, but this is the first report of the effect on the facial skeleton. We used geometric morphometrics (GMM) to analyze the deformations of the murine facial skeleton from the wild-type to the Sost gene knockout. Landmark coordinates were obtained by surface reconstructions from micro-computed tomography. Centroid size, principal component scores in shape space and form space, and asymmetry were computed by the standard GMM formulas, and dental and skeletal jaw lengths were examined as ratios. We show here that, compared to wild type controls, mice lacking Sost have larger centroid size (effect size, p-value: 4.59, <.001), higher mean asymmetry (1.14, .065), dental and skeletal mandibular prognathism (1.36, .010 and 5.92, <.001), a smaller foramen magnum (−1.71, .015), and calvaria that are more highly curved (form space p = 4.09, .002; shape space p = 12.82, .002). These features of mice lacking sclerostin largely correspond to the changes of the facial skeleton observed in sclerosteosis. This alignment further supports claims that the Sost gene plays a fundamental role in bony facial development in rodents and humans alike.

“…In the field of congenital pathological abnormalities, the 3D approach was used to explore the metrical modifications of cleft palate [13][14][15]. Other applications in orthodontics concern the assessment of palatal linear modifications after maxillary expansion therapy [16][17][18]. The main use of the novel technologies relies on the metrical assessment of different parameters, be they linear distances, surfaces or volumes: however, another important tool concerns the chance of superimposing 3D models [11].…”

The modern 3D image acquisition systems have acquired in the last decades a growing importance in clinical anatomy and in different fields of application of physical anthropology, including also forensic issues. An example can be found in the development of novel procedures concerning the comparison of palatal anatomical structures, such as palatal rugae. This study aims at exposing possible protocols of superimposition for the comparison of palatal rugae, useful for clinical and forensic purposes: the palate is acquired by a laser scanner (Dental Wing©). Superimposition is then performed according to the surface of the three main palatal rugae through VAM© software which is able to give back an estimation of RMS (root mean square) point-to-point distance between the two models. Models can be also assessed separating the right and the left side in order to test possible modifications of palatal structures in cases of maxillary expansion. The 3D superimposition provides a chromatic visualization of corresponding areas (areas with full superimposition are represented in green, whereas possible discordances are in blue or red) that offer a visual depiction of the quantified differences, useful in clinical contexts. The proposed protocol may therefore provide a relevant help in the assessment of palatal modifications in clinical anatomy and forensic anthropology.
