The Oral Health Impact Profile-14 (OHIP-14) and KFIA were administered before and after treatment. The American Board of Orthodontics Discrepancy Index and Objective Grading System (OGS) were also evaluated. The primary outcomes were group \u00d7 time interactions in OHIP-14 and KFIA; the secondary outcome was posterior disclusion in ME cases.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Baseline characteristics were similar, except for greater initial overjet and overbite in ME (\n P<\/jats:italic>\n < .05). KFIA remained stable after treatment in all groups (\n P<\/jats:italic>\n \u2265 .05). OHIP-14 improved significantly in total score and psychological discomfort for all patients, with additional improvement in the handicap domain in the MME group; however, no significant group \u00d7 time interactions were found. Baseline OHIP-14 was the only predictor of posttreatment OHRQoL (\n P<\/jats:italic>\n < .001). OGS outcomes were comparable; however, digital analysis showed second-molar posterior disclusion in 10% of ME cases.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Class II camouflage treatment improved psychosocial aspects of OHRQoL regardless of extraction pattern; in contrast, subjective masticatory function remained unchanged. Baseline OHRQoL, rather than extraction type or case complexity, predicted final OHRQoL. Posterior occlusal assessment beyond OGS criteria may be useful in ME cases.<\/jats:p>\n <\/jats:sec>","DOI":"10.2319\/122125-1048.1","type":"journal-article","created":{"date-parts":[[2026,9,26]],"date-time":"2026-09-26T10:00:00Z","timestamp":1790416800000},"source":"Crossref","is-referenced-by-count":0,"title":["Oral health\u2013related quality of life and masticatory function changes in Class II camouflage treatment: focus on maxillary premolar extraction and final posterior occlusion"],"prefix":"10.2319","author":[{"given":"Hyunjae","family":"Lee","sequence":"first","affiliation":[{"name":"Graduate Student, Department of Orthodontics, Yonsei University College of Dentistry, Seoul, Republic of Korea."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Liu","sequence":"additional","affiliation":[{"name":"Researcher, Department of Orthodontics, Institute of Craniofacial Deformity, Yonsei University College of Dentistry, Seoul, Republic of Korea."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huiqing","family":"Han","sequence":"additional","affiliation":[{"name":"Graduate Student, Department of Orthodontics, Yonsei University College of Dentistry, Seoul, Republic of Korea."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sung-Hwan","family":"Choi","sequence":"additional","affiliation":[{"name":"Professor, Department of Orthodontics, Institute of Craniofacial Deformity, Yonsei University College of Dentistry, Seoul, Republic of Korea."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jung-Yul","family":"Cha","sequence":"additional","affiliation":[{"name":"Professor and Chair, Department of Orthodontics, Institute of Craniofacial Deformity, Yonsei University College of Dentistry, Institute for Digital Healthcare, Yonsei University, Seoul, Republic of Korea."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1164","container-title":["The Angle Orthodontist"],"original-title":[],"link":[{"URL":"https:\/\/angle-orthodontist.kglmeridian.com\/view\/journals\/angl\/aop\/article-10.2319-122125-1048.1\/article-10.2319-122125-1048.1.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/angle-orthodontist.kglmeridian.com\/downloadpdf\/journals\/angl\/aop\/article-10.2319-122125-1048.1\/article-10.2319-122125-1048.1.xml","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,28]],"date-time":"2026-09-28T12:02:42Z","timestamp":1790596962000},"score":1,"resource":{"primary":{"URL":"https:\/\/angle-orthodontist.kglmeridian.com\/view\/journals\/angl\/aop\/article-10.2319-122125-1048.1\/article-10.2319-122125-1048.1.xml"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,8,5]]},"references-count":0,"URL":"https:\/\/doi.org\/10.2319\/122125-1048.1","relation":{},"ISSN":["1945-7103","0003-3219"],"issn-type":[{"value":"1945-7103","type":"electronic"},{"value":"0003-3219","type":"print"}],"subject":[],"published":{"date-parts":[[2026,8,5]]}}}
