Nevertheless, its potential impact on periodontal tissues, particularly gingival recession (GR), remains a matter of clinical concern. This study aimed to evaluate the relationship between orthodontic\u2013orthognathic procedures and GR based on available clinical evidence, with particular focus on potential risk modifiers, including orthodontic mechanics, surgical factors, and periodontal phenotype. Materials and Methods: This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. The review question was formulated using the PICO framework. Results: Seven observational clinical studies were included, with sample sizes ranging from 24 to 40 patients. GR outcomes varied considerably according to surgical procedure, orthodontic mechanics, adjunctive therapies, and patient-specific factors. Overall certainty of evidence was low\u2013moderate. Conclusions: GR following combined orthodontic\u2013orthognathic treatment is inconsistently reported and influenced by multiple clinical variables. Evidence suggesting roles for periodontal phenotype and adjunctive therapies, including PAOO, remains limited and context-dependent. Overall certainty of evidence is low\u2013moderate, and findings should be interpreted cautiously.<\/jats:p>","DOI":"10.3390\/jcm15051793","type":"journal-article","created":{"date-parts":[[2026,2,27]],"date-time":"2026-02-27T10:41:02Z","timestamp":1772188862000},"page":"1793","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Gingival Recession After Combined Orthodontic\u2013Orthognathic Treatment: A Systematic Review of Clinical Studies with Emphasis on Mandibular Incisors and Adjunctive Periodontal Therapies"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3393-4307","authenticated-orcid":false,"given":"Alexandru","family":"Mester","sequence":"first","affiliation":[{"name":"Department of Oral Health, University of Medicine and Pharmacy \u201cIuliu Hatieganu\u201d, 400012 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1087-8522","authenticated-orcid":false,"given":"Gabriel","family":"Armencea","sequence":"additional","affiliation":[{"name":"Department of Maxillofacial Surgery and Implantology, University of Medicine and Pharmacy \u201cIuliu Hatieganu\u201d, 400012 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6807-6162","authenticated-orcid":false,"given":"Andrei","family":"Tent","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillo-Facial Surgery, Faculty of Medicine and Pharmacy, University of Oradea, 410087 Oradea, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dacian","family":"Sabau","sequence":"additional","affiliation":[{"name":"Department of Maxillofacial Surgery and Implantology, University of Medicine and Pharmacy \u201cIuliu Hatieganu\u201d, 400012 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1076-7726","authenticated-orcid":false,"given":"Florin Gligor","family":"Onisor","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillo-Facial Surgery, Faculty of Medicine and Pharmacy, University of Oradea, 410087 Oradea, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Simion","family":"Bran","sequence":"additional","affiliation":[{"name":"Department of Oral Health, University of Medicine and Pharmacy \u201cIuliu Hatieganu\u201d, 400012 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1063","DOI":"10.1016\/j.ijporl.2015.04.027","article-title":"A retrospective analysis of dentofacial deformities and orthognathic surgeries using the index of orthognathic functional treatment need (IOFTN)","volume":"79","author":"Harrington","year":"2015","journal-title":"Int.
