Despite being perceived as a minor health condition, presence of uneven gingival margins usually impacts the smile aesthetics and could affect the individual's appearance, self\u2010esteem, and overall quality of life, especially in subjects with a high smile line. Uneven gingival margins may result from different causes, which makes an accurate diagnosis fundamental for its treatment planning. Orthodontic treatment often serves as a conservative approach for leveling these margins, by achieving the most appropriate tooth position. This article reviews the rationale, differential diagnosis, and clinical management of uneven gingival margins using orthodontic tooth movements, providing insights for orthodontists, periodontists, and restorative dentists on the interdisciplinary care needed to correct this condition, and hence, to improve the subject's smile aesthetics.<\/jats:p>","DOI":"10.1111\/prd.12613","type":"journal-article","created":{"date-parts":[[2024,10,17]],"date-time":"2024-10-17T04:21:51Z","timestamp":1729138911000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Orthodontic management of uneven gingival margins in patients with healthy or reduced periodontium to improve smile aesthetics"],"prefix":"10.1111","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3997-6900","authenticated-orcid":false,"given":"Conchita","family":"Martin","sequence":"first","affiliation":[{"name":"Section of Orthodontics, Department of Dental Clinical Specialties Complutense University of Madrid  Madrid Spain"},{"name":"BIOCRAN (Craniofacial Biology: Orthodontics and Dentofacial Orthopedics) Research Group Complutense University of Madrid  Madrid Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1968-3326","authenticated-orcid":false,"given":"Spyridon N.","family":"Papageorgiou","sequence":"additional","affiliation":[{"name":"Clinic of Orthodontics and Pediatric Dentistry, Center for Dental Medicine University of Zurich  Zurich Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3957-4872","authenticated-orcid":false,"given":"Oscar","family":"Gonzalez\u2010Martin","sequence":"additional","affiliation":[{"name":"Department of Restorative Dentistry and Biomaterials Sciences Harvard School of Dental Medicine  Boston USA"},{"name":"Section of Periodontics, Department of Dental Clinical Specialties Complutense University of Madrid  Madrid Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1287-6320","authenticated-orcid":false,"given":"Mariano","family":"Sanz","sequence":"additional","affiliation":[{"name":"Section of Periodontics, Department of Dental Clinical Specialties Complutense University of Madrid  Madrid Spain"},{"name":"ETEP (Etiology and Therapy of Periodontal and Peri\u2010implant Diseases) Research Group Complutense University of Madrid  Madrid Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,10,16]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1080\/00016357.2020.1758773"},{"issue":"2","key":"e_1_2_8_3_1","doi-asserted-by":"crossref","first-page":"162","DOI":"10.15644\/asc56\/2\/7","article-title":"Impact of gingival margin asymmetries on the smile esthetic perception of dental specialists, doctors of dental medicine, students, and laypeople: a comparative pilot study","volume":"56","author":"\u010calu\u0161i\u0107 \u0160arac M","year":"2022","journal-title":"Acta Stomatol Croat"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajodo.2017.12.010"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.2319\/082606-349"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.prosdent.2021.04.005"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.14219\/jada.archive.2008.0043"},{"volume-title":"Bonded Porcelain Restorations in the Anterior Dentition.
