This treatment was proposed to improve incisor inclination and overjet while minimizing further biological risk and preserving long-term tooth vitality. A 13-year-old female patient with a history of prior orthodontic treatment presented with excessive maxillary incisor flaring, increased overjet, and radiographic evidence of moderate-to-severe external apical root resorption. Comprehensive clinical and radiographic examinations revealed shortened roots with open apices, though periodontal support and pulpal vitality were preserved. Treatment planning focused on minimizing additional root resorption through conservative biomechanics. Space was gained by extracting the maxillary second premolars, allowing controlled retraction of the maxillary incisors using light orthodontic forces. Periodontal health and pulpal vitality were closely monitored throughout the treatment. Significant improvements in maxillary incisor inclination, a reduction of overjet, and enhanced facial harmony were noted. Periodontal probing depths remained within normal limits, no pathological tooth mobility was observed, and pulpal vitality tests remained positive. Although root shortening persisted radiographically, no progression of root resorption was detected during treatment. Orthodontic re-treatment in adolescents with severe external apical root resorption can be successfully performed using conservative biomechanics and careful force control, achieving functional and esthetic improvements while preserving periodontal health and tooth vitality.<\/jats:p>","DOI":"10.4103\/jos.jos_83_26","type":"journal-article","created":{"date-parts":[[2026,9,16]],"date-time":"2026-09-16T13:01:01Z","timestamp":1789563661000},"update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Conservative orthodontic re-treatment management of severely proclined upper anterior teeth with root resorption"],"prefix":"10.4103","volume":"15","author":[{"given":"Joko","family":"Kusnoto","sequence":"first","affiliation":[{"name":"Department of Orthodontics, Faculty of Dentistry, Universitas Trisakti, Jakarta, Indonesia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Ketherin","sequence":"additional","affiliation":[{"name":"Private Practice in Periodontics, Jakarta, Indonesia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Endah","family":"Mardiati","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, Faculty of Dentistry, Universitas Padjadjaran, Bandung, Indonesia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Budi","family":"Kusnoto","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, Faculty of Dentistry, University of Illinois at Chicago, Chicago, United States"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2026,9]]},"reference":[{"key":"R1-20260916","doi-asserted-by":"crossref","first-page":"20","DOI":"10.1038\/s41368-021-00125-5","article-title":"Biomechanical and biological responses of the periodontium in orthodontic tooth movement: Update in a new decade","volume":"13","author":"Li","year":"2021","journal-title":"Int J Oral Sci"},{"key":"R2-20260916","doi-asserted-by":"crossref","first-page":"4035","DOI":"10.3390\/app13064035","article-title":"Complications arising due to orthodontic treatment: A systematic review and meta-analysis","volume":"13","author":"Alam","year":"2023","journal-title":"Appl Sci (Basel)"},{"key":"R3-20260916","doi-asserted-by":"crossref","first-page":"341","DOI":"10.1038\/s41415-024-7781-1","article-title":"The role of orthodontics in the prevention and management of gingival recession","volume":"237","author":"Fleming","year":"2024","journal-title":"Br Dent J"},{"key":"R4-20260916","doi-asserted-by":"crossref","first-page":"1603","DOI":"10.1186\/s12889-023-16241-2","article-title":"Oral-health-related quality of life in adolescents: Umbrella review","volume":"23","author":"Chimbinha","year":"2023","journal-title":"BMC Public Health"},{"key":"R5-20260916","doi-asserted-by":"crossref","first-page":"38","DOI":"10.1186\/s40510-023-00491-2","article-title":"Displacement of teeth and stress distribution on the periodontal ligament under different upper incisor proclinations with clear aligners in extraction cases: A finite element study","volume":"24","author":"Kang","year":"2023","journal-title":"Prog Orthod"},{"key":"R6-20260916","doi-asserted-by":"crossref","first-page":"135","DOI":"10.1111\/prd.12484","article-title":"Complications and treatment errors involving periodontal tissues related to orthodontic therapy","volume":"92","author":"Jepsen","year":"2000","journal-title":"Periodontol"},{"key":"R7-20260916","doi-asserted-by":"crossref","first-page":"2388","DOI":"10.3390\/ijms22052388","article-title":"Is inflammation a friend or foe for orthodontic treatment?
