Group I included 16 early mixed dentition patients (age 7\u20139 years); Group II included 16 late mixed dentition patients (age 11\u201313 years). All patients received a palatal miniplate with a face mask. Pre- and post-treatment skeletal, dental, and soft tissue measurements were analysed. Statistical evaluation included paired t-tests, inter-group comparisons, Bonferroni correction, and effect size calculation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Skeletal changes (SNA (angle between S, Nasion and A points), ANB (angle between A, Nasion and B points), angle of convexity, maxillary length) were significantly greater in early mixed dentition. Dental changes were more pronounced in late mixed dentition, especially upper incisor proclination (Upper 1\/SN: 7.20\u00b0 vs. 2.85\u00b0). Soft tissue improvements were greater in early mixed dentition, with an H-angle increase of 7.71\u00b0 vs. 3.90\u00b0. Early intervention achieved greater skeletal-driven overjet correction, while late intervention relied more on dental compensation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Timing of palatal plate\u2013assisted maxillary protraction significantly influences treatment outcomes.
