Maxillary expanders supported by two paramedian miniscrews were placed in the anterior palate. Cone-beam computed tomography (CBCT) scans were obtained before expansion (T1) and after 3 weeks of active expansion (T2) to evaluate changes in MPS width at the premolar and first molar regions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>\n                      Post-expansion measurements demonstrated a statistically significant increase in midpalatal sutural width at all evaluated sites\u2014including the first premolar, second premolar, and first molar regions\u2014compared with baseline (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.001). Greater sutural opening was observed in the premolar regions than in the molar region, indicating a V-shaped expansion pattern. Increased variability in post-expansion measurements was also noted. Patients classified as stage C showed statistically significant increases in sutural width at all sites following expansion (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.005), whereas stage D patients exhibited minimal, non-significant changes (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.068).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSION:<\/jats:title>\n                    <jats:p>The two-miniscrew MARPE appliance produced significant midpalatal sutural expansion in post-pubertal patients with incomplete sutural maturation.
