The majority of studies however focus on relapse of the increase in the transverse dimension, but not relapse of the crossbite itself, which is an essential outcome. The aim of the present study was to determine long\u2010term stability (2\u2009years minimum post\u2010treatment) of posterior crossbite correction, treated in mixed or early permanent dentitions of growing children. Following registration in PROSPERO (CRD42022348858), an electronic literature search including PubMed, Embase, Web of Science, the Cochrane Library, and a manual search were conducted up to January 2023, to identify longitudinal studies looking into the long\u2010term stability of crossbite correction in growing children. Data extraction and risk of bias assessment were carried out, and subsequently, a random\u2010effects meta\u2010analyses models were used to calculate estimates for relapse of the crossbite and relapse at the transverse level. Twenty\u2010two studies were included, of varying designs and quality, representing 1076 treated patients, with different expansion appliances and protocols. Meta\u2010analysis results showed that 19.5% (95% CI: 15%; 25%) of patients present with relapse of posterior crossbite at long\u2010term follow\u2010up. At the transverse level, 19.3% of the total expansion (including overexpansion) relapsed (95% CI: 13%; 27%) regardless of whether there a was relapse of the crossbite itself. Data from existing studies, with a moderate level of evidence, indicate that the long\u2010term stability of posterior crossbite correction in growing children is unfavourable in roughly 1 in 5 growing children, with crossbite relapse long\u2010term. On average, 19% of the maxillary expansion performed (including overexpansion) relapses long\u2010term, which may occur in cases with or without relapse of the crossbite.<\/jats:p>","DOI":"10.1111\/ocr.12690","type":"journal-article","created":{"date-parts":[[2023,7,9]],"date-time":"2023-07-09T07:04:16Z","timestamp":1688886256000},"page":"1-14","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Long\u2010term stability of posterior crossbite correction, treated in the mixed or permanent dentition of growing children: A systematic review and meta\u2010analysis"],"prefix":"10.1111","volume":"27","author":[{"given":"Fara","family":"Beltrami","sequence":"first","affiliation":[{"name":"Division of Orthodontics University Clinics of Dental Medicine, University of Geneva  Geneva Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stavros","family":"Kiliaridis","sequence":"additional","affiliation":[{"name":"Division of Orthodontics University Clinics of Dental Medicine, University of Geneva  Geneva Switzerland"},{"name":"Department of Orthodontics and Dentofacial Orthopedics, Dental School\/Medical Faculty University of Bern  Bern Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6741-6922","authenticated-orcid":false,"given":"Gregory S.","family":"Antonarakis","sequence":"additional","affiliation":[{"name":"Division of Orthodontics University Clinics of Dental Medicine, University of Geneva  Geneva Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,7,9]]},"reference":[{"key":"e_1_2_11_2_1","first-page":"411","article-title":"Maxillary expansion of unilateral cross\u2010bite in preschool children","volume":"94","author":"Linder A","year":"1986","journal-title":"Scan J Dent Res"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1590\/2177-6709.23.6.40.e1-10.onl"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9416(82)90285-8"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9416(78)90183-5"},{"key":"e_1_2_11_6_1","first-page":"73","article-title":"Rapid expansion of the maxillary dental arch and nasal cavity by opening the midpalatal suture","volume":"31","author":"Haas AJ","year":"1961","journal-title":"Angle Orthod"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1590\/2177-6709.22.2.035-044.oar"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/ocr.12244"},{"key":"e_1_2_11_9_1","first-page":"155","article-title":"Long\u2010term dental arch changes after rapid maxillary expansion treatment:a systematic review","volume":"75","author":"Lagravere MO","year":"2005","journal-title":"Angle Orthod"},{"key":"e_1_2_11_10_1","first-page":"1046","article-title":"Long\u2010term skeletal changes with rapid maxillary expansion:a systematic review","volume":"75","author":"Lagravere MO","year":"2005","journal-title":"Angle Orthod"},{"key":"e_1_2_11_11_1","doi-asserted-by":"publisher","DOI":"10.5005\/jp-journals-10024-2932"},{"key":"e_1_2_11_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jclinepi.2009.06.006"},{"key":"e_1_2_11_13_1","first-page":"463","article-title":"Volumetric upper airway changes after rapid maxillary expansion: a systematic review and meta\u2010analysis","volume":"39","author":"Buck LM","year":"2017","journal-title":"Eur J Orthod"},{"key":"e_1_2_11_14_1","unstructured":"WellsGA SheaB O'ConnellD et al.The Newcastle\u2010Ottawa Scale (NOS) for assessing quality of nonrandomised studies in meta\u2010analysis.
