A 26-year-old woman had a history of fixed treatment with the extraction of her four first premolars and splint therapy because of temporomandibular disorder. She had a normally positioned maxilla (SNA, 82.1°), retrusive mandible (SNB, 74.0°), skeletal Class II malocclusion (ANB, 8.1°; overjet, 6.9 mm), and shallow overbite (0.4 mm). In stage 1 treatment, with the help of four OMIs installed at the palate and the buccal attached gingiva of the mandible, a series of 34 clear aligners were applied to obtain intrusion of the maxillary and mandibular posterior teeth and sequential distalization of the maxillary teeth, and mesialization of the mandibular teeth. Counterclockwise rotation of the mandible, distal movement of the maxillary dentition, and mesial movement of the mandibular dentition helped to obtain a Class I relationship. Stage 2 treatment was performed with 15 sets of aligners and OMIs for additional distalization of the maxillary teeth and intrusion of the maxillary and mandibular anterior teeth. Improvement of the retrusive mandible (SNB, 76.0°), Class I relationship, and normal overbite and overjet (3.1 mm; 2.7 mm) were obtained. The total treatment duration was 1 year and 5 months. Treatment outcomes were well maintained at 1-year retention. Combining clear aligners and OMIs might help clinicians obtain good treatment outcomes in retreatment of Class II malocclusion and excessive overjet. However, meticulous monitoring of the counterclockwise rotation of the mandible and the resulting change in overbite and overjet is necessary.</div></div>","PeriodicalId":72140,"journal":{"name":"AJO-DO clinical companion","volume":"4 6","pages":"Pages 469-482"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143179937","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}

However, it is associated with dentoalveolar side effects such as mandibular incisor protrusion, limiting its effectiveness. In this study, we introduced the bimaxillary anchored Forsus-FRD appliance system with a superior anchorage mechanism. The appliance design incorporates a fail-safe attachment system, offering the following advantages: fail-safe design, customizable dimensions, simple fabrication, cost-effectiveness, versatility in angulation, and a quick-release system. The bimaxillary anchored Forsus-FRD demonstrated skeletal Class II correction with greater skeletal and less dentoalveolar effects. The technique resulted in increased mandibular length, anterior mandibular positioning, and minimal posterior displacement of the maxillary region. Dental changes included retroclination of maxillary incisors and limited proclination of mandibular incisors. The molar relationship was corrected to Class I, primarily because of skeletal changes. Soft tissue analysis showed improved facial esthetics, with notable improvement in the position of the lower lip. The bimaxillary miniplate–anchored Forsus-FRD offers an effective treatment modality for patients in late adolescence, either because of noncompliance with removable functional appliances or those who consult the orthodontist at an older age. This technique not only minimizes the undesirable effects but also circumvents the need for orthognathic surgery by using residual growth.</div></div>","PeriodicalId":72140,"journal":{"name":"AJO-DO clinical companion","volume":"4 6","pages":"Pages 445-468"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143179938","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}

However, it has been difficult for clinicians to obtain accurate 3D soft-tissue images because of the technique sensitivity and the challenges in the superimposition of the 3D skeletal, dental, and soft-tissue information.
