The diagnostic and treatment details of the present case were documented in accordance with the CARE guidelines for clinical case reporting. This case report describes the successful non-surgical management of an 18-year-old female with severe anterior open bite, hyperdivergent facial morphology, bilateral posterior crossbite, and an atrophic mandibular first molar extraction site with a mesially and lingually tipped second molar. The patient declined orthognathic surgery, leading to the consideration of a comprehensive orthodontic approach in conjunction with Miniscrew-Assisted Rapid Palatal Expansion (MARPE) for transverse correction, skeletal anchorage for maxillary molar intrusion, and fixed orthodontic appliances for space closure and molar uprighting. Treatment resulted in a functional occlusion with Class I molar and canine relationships, normal overjet and overbite, and stable transverse correction. The patient received satisfactory facial aesthetics with a harmonious smile and was pleased with the results. The integration of skeletal anchorage enabled effective vertical and transverse correction in an adult patient without orthognathic surgery. Controlled uprighting with intrusion allowed for proper alignment of a tipped mandibular molar, followed by successful protraction across an atrophic ridge.</div></div>","PeriodicalId":45449,"journal":{"name":"International Orthodontics","volume":"24 1","pages":"Article 101072"},"PeriodicalIF":1.9,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145201708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to objectively evaluate the quality of the occlusal outcome and the transverse correction after non-surgical crossbite correction in adults compared to adult patients with no pretreatment crossbite.</div></div><div><h3>Material and methods</h3><div>This retrospective study included 80 adult patients treated consecutively with completely customized lingual appliances (CCLAs) between 2019 and 2021. Crossbite correction was performed with CAD/CAM expansion archwires in the maxilla and compression archwires in the mandible. Occlusal outcome was evaluated using the American Board of Orthodontics (ABO) Model Grading System (MGS), and transverse metric measurements were performed, both on plaster models before treatment (T1), on the set-up models (T2A) and after debonding (T2B).</div></div><div><h3>Results</h3><div>From a total of 1098 patients debonded during the observation period, 40 patients (f/m 30/10, mean age 33.6<!--> <!-->±<!--> <!-->10.9<!--> <!-->years) with unilateral or bilateral crossbite were enrolled in the crossbite group. The matched non-crossbite control group consisted of 40 Class I patients (f/m 30/10, mean age 30.7<!--> <!-->±<!--> <!-->9.1<!--> <!-->years). No statistically significant difference was observed between the crossbite and non-crossbite groups regarding the total ABO score at T2B (20.7 vs. 18.8, <em>p</em> <!-->&gt;<!--> <!-->0.05), despite the malocclusion being significantly more severe in the crossbite group at T1 (68.1 vs. 41.0, <em>p</em> <!-->&lt;<!--> <!-->0.001). In both groups, 38 out of 40 patients (95%) would have passed the ABO examination (total score at T2B<!--> <!-->≤<!--> <!-->25). All crossbites were completely corrected at T2B, with a mean total transverse correction of 6.7<!--> <!-->±<!--> <!-->2.3<!--> <!-->mm (3.2<!--> <!-->±<!--> <!-->2.1<!--> <!-->mm maxillary expansion, 3.5<!--> <!-->±<!--> <!-->2.4<!--> <!-->mm mandibular compression).</div></div><div><h3>Conclusion</h3><div>Non-surgical crossbite correction did not lead to compromised occlusal results. CCLAs in combination with CAD/CAM expansion and compression archwires can correct posterior crossbites successfully in adult patients. The final occlusal outcome can be of a similar high quality in crossbite and non-crossbite patients.</div></div>","PeriodicalId":45449,"journal":{"name":"International Orthodontics","volume":"23 3","pages":"Article 101040"},"PeriodicalIF":1.8,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144696641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
