This becomes critical when palatal bone is thin at the miniscrew insertion sites, potentially leading to miniscrew failure. In this article, a maxillary skeletal expander (MSE), a particular type of MARPE appliance, was adopted to skeletally expand the maxilla in a postpubertal patient with a thin palatal bone. To reinforce the skeletal anchorage, the MSE was modified by adding 2 lateral miniscrews in the palatal slope between the second premolar and first molar. A virtual model of the MSE with 4 miniscrews was imported into the merged model of the patient's cone-beam computed tomography and maxillary dental arch. Then, a computer-aided design/manufacturing structure with appliance arms, 2 bushings for additional lateral miniscrews, and molar bands was 3-dimensionally designed and manufactured with selective laser melting technology and was laser welded to the MSE body to produce the modified MSE with 6 miniscrews. Because appliance arms tend to slide along the additional lateral miniscrews during maxillary expansion because of the lateral force vector, a steel ligature (the “tadlock”) is tied between the miniscrew head and the bushing pin present on the appliance arms to eliminate the problem. The digital workflow to fabricate the MSE with 6 miniscrews and the tadlock mechanism are presented along with the procedure to expand the maxilla in a postpubertal patient with a thin palatal bone.</div></div>","PeriodicalId":72140,"journal":{"name":"AJO-DO clinical companion","volume":"5 3","pages":"Pages 260-269"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144271814","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}

A 38-year-old male was referred for molar uprighting before implant placement in the mandibular right second premolar and first molars. To avoid low bone density in the retromolar triangle and mobile soft tissue in the retromolar pad, a mini-implant was strategically placed on the distal side of the mandibular right second molar to ensure better bone quality and minimal soft tissue irritation. A lever extension was placed in the bracket slot on the mini-implant head using the novel subslot overtie method through the hole beneath the bracket. This setup directed the distal traction force through the molar's center of resistance in the occlusal plane, preventing undesirable rotational moments. To generate an intrusive force on the distal marginal ridge, an elastomeric chain configured in a slingshot manner was applied from a button on the mesial surface of the second molar to the lever extension, crossing over the occlusal surface. The treatment was completed within 5 months. For retention, a minitube was bonded to the distal surface of the second molar and ligated into the lever. Using this lever extension allowed ideal placement of the mini-implant, enabling a straightforward force application that included an intrusive component while minimizing unwanted movements.</div></div>","PeriodicalId":72140,"journal":{"name":"AJO-DO clinical companion","volume":"5 2","pages":"Pages 156-163"},"PeriodicalIF":0.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143825816","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}
