The patient presented with a Class III malocclusion (Angle classification), anterior and posterior crossbite, maxillary hypoplasia, and compromised facial esthetics. The treatment protocol consisted of 12 months of MPFM with HME, followed by retention using a modified Type III activator and chin cup, and subsequent fixed orthodontic therapy for final occlusal refinement. Cephalometric evaluation demonstrated significant skeletal improvements, with the ANB angle increasing from \u22121.0\u00b0 to 3.1\u00b0, the SNA angle increasing from 82.0\u00b0 to 84.2\u00b0, and the SNB angle decreasing from 83.0\u00b0 to 81.1\u00b0. A marked increase in maxillary incisor inclination was observed, with the U1\u2013NA angle increasing from 24.5\u00b0 to 33.8\u00b0. Mandibular incisors exhibited minor linear positional changes (L1\u2013NB, millimeters) and a reduction in angular inclination (L1.NB), indicating dentoalveolar adaptation during treatment. The overjet correction was particularly notable, improving from \u22121.7 to 3.4\u2009mm, whereas enhanced lip support contributed to improved facial esthetics. The 9\u2010year follow\u2010up examination revealed excellent stability in maxillomandibular relationships, with maintained molar and incisor positions as well as stable overjet and overbite measurements. This case demonstrates that early intervention combining HME and MPFM can effectively correct Class III malocclusion with maxillary hypoplasia and mandibular prognathism. However, the importance of continued growth monitoring following active treatment cannot be overstated, as residual growth patterns may influence long\u2010term stability. These findings support the use of interceptive orthopedic approaches in growing Class III patients while emphasizing the need for extended follow\u2010up through the remaining growth period. This stability is interpreted considering growth\u2010related drift: the postpubertal reduction in ANB and overjet reflects residual mandibular growth rather than relapse, whereas stable incisor proclination contributed to occlusal maintenance.<\/jats:p>","DOI":"10.1155\/crid\/2771248","type":"journal-article","created":{"date-parts":[[2026,5,27]],"date-time":"2026-05-27T01:41:26Z","timestamp":1779846086000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Long\u2010Term Outcomes of Class III Malocclusion Interception With Maxillary Expansion and Protraction: A 9\u2010Year Follow\u2010Up Case Report"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5524-8538","authenticated-orcid":false,"given":"Jenny Ang\u00e9lica","family":"Saldarriaga-Valencia","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3355-0001","authenticated-orcid":false,"given":"Ary","family":"dos Santos-Pinto","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3663-1416","authenticated-orcid":false,"given":"Carlos M.","family":"Ardila","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,5,26]]},"reference":[{"key":"e_1_2_13_1_2","doi-asserted-by":"publisher","DOI":"10.2319\/112609-672.1"},{"key":"e_1_2_13_2_2","doi-asserted-by":"publisher","DOI":"10.23804\/ejpd.2019.20.04.14"},{"key":"e_1_2_13_3_2","doi-asserted-by":"publisher","DOI":"10.1080\/14653125.2016.1201302"},{"key":"e_1_2_13_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajodo.2021.02.027"},{"key":"e_1_2_13_5_2","doi-asserted-by":"publisher","DOI":"10.1067\/mod.2001.110985"},{"key":"e_1_2_13_6_2","doi-asserted-by":"publisher","DOI":"10.1093\/ejo\/23.2.153"},{"key":"e_1_2_13_7_2","doi-asserted-by":"publisher","DOI":"10.2147\/CCIDE.S134303"},{"key":"e_1_2_13_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0889-5406(98)70306-3"},{"key":"e_1_2_13_9_2","first-page":"314","article-title":"Orthopedic Correction of Class III Malocclusion With Palatal Expansion and Custom Protraction Headgear","volume":"22","author":"Turley P.
