Materials and Methods: MEDLINE, Scopus, Cochrane Oral Health Group\u2019s Trials Register, and ScienceDirect electronic databases were systematically searched with no publication date restrictions up to January 2021. Data assessing the status of ICI after combined surgical-orthodontic treatment and forced eruption duration were extracted, and the quality of the studies was evaluated. Results: In total, 7074 studies were identified, of which 42 articles were assessed for eligibility through full-text evaluation. Seven included studies\u00a0(five retrospective studies, one randomized clinical trial, and one prospective clinical trial) met the inclusion criteria, representing 211 patients with unilaterally impacted maxillary incisors. The risk of bias ranged from moderate to high. The results show that the root length of immature ICIs increased significantly but remained shorter than that of homonym teeth at post-treatment. Periodontal parameters of treated ICIs were in a clinically acceptable range. Measurements of the alveolar bone showed a reduction of bone thickness and support. The average forced eruption duration ranged from 8.0 \u00b1 4.5 to 14.41 \u00b1 4.03 months. Conclusions: Based on existing evidence, it is reasonable to conclude that the surgical-orthodontic treatment affected the post-treatment status of ICI; however, the current literature is insufficient to draw concrete conclusions. Further well-conducted multi-center randomized studies with a large sample are needed to confirm this statement.<\/jats:p>","DOI":"10.3390\/medicina57080783","type":"journal-article","created":{"date-parts":[[2021,8,1]],"date-time":"2021-08-01T21:44:32Z","timestamp":1627854272000},"page":"783","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Post-Treatment Status of Impacted Maxillary Central Incisors following Surgical-Orthodontic Treatment: A Systematic Review"],"prefix":"10.3390","volume":"57","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2175-0524","authenticated-orcid":false,"given":"Alvyda","family":"\u017darovien\u0117","sequence":"first","affiliation":[{"name":"Department of Orthodontics, Medical Academy, Lithuanian University of Health Sciences, Luk\u0161os-Daumanto 6, LT-50106 Kaunas, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dominyka","family":"Grinkevi\u010dien\u0117","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, Medical Academy, Lithuanian University of Health Sciences, Luk\u0161os-Daumanto 6, LT-50106 Kaunas, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giedr\u0117","family":"Trakinien\u0117","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, Medical Academy, Lithuanian University of Health Sciences, Luk\u0161os-Daumanto 6, LT-50106 Kaunas, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2173-599X","authenticated-orcid":false,"given":"Dalia","family":"Smailien\u0117","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, Medical Academy, Lithuanian University of Health Sciences, Luk\u0161os-Daumanto 6, LT-50106 Kaunas, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"420","DOI":"10.1016\/0030-4220(85)90070-2","article-title":"The incidence of unerupted permanent teeth and related clinical cases","volume":"59","author":"Grover","year":"1985","journal-title":"Oral Surgery, Oral Med.
