There are many causes of anterior crossbite, and the presence of supernumerary tooth\/teeth is one of them. Early interceptive intervention is essential to avoid the need for more complex orthodontic treatment later. This case report describes the management of a 10\u2010year\u2010old child who presented with anterior crossbite involving Teeth 21 and 31, leading to gingival recession of Tooth 31. The crossbite malocclusion was associated with a supernumerary tooth in the upper incisor region. Extraction of the supernumerary tooth was performed, and correction of the anterior crossbite was commenced with a 2 \u00d7 4 appliance. Adequate stability with a positive overjet was observed at the 6\u2010month review. The 2 \u00d7 4 orthodontic appliance may be considered a treatment option for correcting anterior crossbite in patients with poor compliance with removable appliance therapy.<\/jats:p>","DOI":"10.1155\/crid\/1417850","type":"journal-article","created":{"date-parts":[[2026,8,8]],"date-time":"2026-08-08T07:01:41Z","timestamp":1786172501000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Correction of Supernumerary Tooth\u2010Associated Anterior Crossbite in Mixed Dentition Using a 2\u2009\u00d7\u20094 Appliance"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1387-5848","authenticated-orcid":false,"given":"Prasanna","family":"Chandraseharan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-7197-5709","authenticated-orcid":false,"given":"Bavani Sinnumu","family":"Naidu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-4200-7177","authenticated-orcid":false,"given":"Thaarani","family":"Vijayakumar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7976-5115","authenticated-orcid":false,"given":"S.
