In the literature, several treatment options have been proposed, including orthodontic space opening with prosthetic replacements or autotransplantation and orthodontic space closure with prosthetic or restorative camouflage. The ideal treatment is the most conservative approach that fulfills both functional and esthetic needs, while being tailored to the patient. The introduction of temporary skeletal anchorage devices has broadened the possibilities for tooth movement, making orthodontic space closure a predictable and feasible treatment alternative in complex cases. Implants in the esthetic zone of young patients represent a significant challenge in terms of long-term maintenance and esthetic stability; therefore, skeletal anchorage provides valuable therapeutic potential within a multidisciplinary treatment approach. This case report describes the successful management of a young patient with hypodontia treated using lingual orthodontics with skeletal anchorage and final esthetic veneers. The interdisciplinary collaboration, combined with accurate case planning and setup, allowed for optimal functional and esthetic outcomes, while avoiding the long-term risks associated with implant placement in the esthetic zone.</div></div>","PeriodicalId":72140,"journal":{"name":"AJO-DO clinical companion","volume":"6 3","pages":"Pages 213-223"},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148141281","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 treatment plan was designed to minimize the financial burden on the patient while providing her with a stable, long-term solution. Using light intermittent forces, the maxillary right lateral incisor (UR2) was moved into the UR1 area to eliminate the bony defect, while generating bone behind it for implant placement. Periodic periapical radiographs were taken to monitor root resorption and the integrity of the periodontal ligament during treatment. An implant was placed in the UR2 area during the orthodontic treatment, and the implant crown was delivered the same day orthodontic treatment was concluded. The UR2 was restored with a composite filling to resemble a maxillary central incisor. All posterior spaces were closed. After 35 months of treatment, the patient achieved an improved smile with a Class I canine relationship and a balanced occlusion without spaces.
