The hard palate and mid-palatal suture are highly important for orthodontic treatment. In cases of transverse maxillary deficiency, palatal expansion is the treatment of choice. As nowadays a growing number of adult patients receive orthodontic treatment, an understanding of suture development throughout life is important to derive tailored orthodontic treatment techniques for each age group. Histological, histochemical and immunohistochemical stains (haematoxylin & eosin, Azan, Movat pentachrome, Masson-Goldner trichrome, Sirius Red, CD 31, osteopontin and TRAP) and histomorphometric analyses were re-established to detect the structural conditions of the mid-palatal suture in human cadavers of three different age groups (20-39, 40-59 and 60-80 years). The mid-palatal suture of the selected age groups (total of n = 12; n = 4 in every group m = f) exhibited marked differences in sutural morphology and metabolism. A wide, interdigitated and well-vascularized suture was observed in younger specimens compared with straighter and smaller sutures with fewer vessels and lower bone density in the 60-80 year group. The fibre composition within the sutural gap differed between the three age groups. Delicate fibres were found in the 20-39 year group, and a tightly interwoven 3D fibre-network was observed in the 40-59 year group. Atrophy primarily characterized the fibres in the 60-80 year group. This evidence demonstrates differences between the evaluated groups. These results suggest that the staining methods used are suitable for the description and evaluation of the morphology and metabolism of mid-palatal sutures. Further investigation is necessary to provide an in-depth description of sutural maturation over a lifetime.

“…The measured mean value of the gap width in the upper jaw after transverse expansion at the end of the therapy period (4.0 mm, SD 1.2) corresponded to the following published values for transverse expansion (with the reminder that these were only measured on plaster models after the end of treatment! ): 2.9 mm (SD 1.68) [3], 3 mm [8], 3.01 mm (SD 1.82) [5], 3.5 (SD 1.54) [14], 3.9 mm (SD 2.1) [4], and 4.62 (SD 1.16) [19]. The recently published high value of 6.18 mm (SD 1.82) [18] was obtained by measuring three-dimensional (3D) X-ray images and differs greatly from all other published data.…”

Comparison of a Modified RME Appliance with Other Appliances for Transverse Maxillary Expansion

Abstract: The modified RME appliance can be used effectively for rapid maxillary expansion in the early mixed dentition. At the end of the retention phase, the overall effect of the modified appliance is similar to that of the other methods.
