The ATOZ™ orthodontic distractor was invented in 2017 in Korea with the primary directive of growing the maxillary apical base without involving teeth or general anesthesia-required surgery in its application. Its 8.2 mm transverse footprint is ideal for patients who display craniofacial dysmorphism with a severely constricted maxillary apical base. ATOZ™ can withstand up to 50 kg-force of compression without permanent deformation and reverts to its original shape effortlessly. This unique property allows ATOZ™ to apply heavy orthopedic force to the median palatine suture and circummaxillary sutures in a continuous manner over a long period of time. Three exemplary clinical cases treated with ATOZ™ are presented in this article with an emphasis on its slow activation protocol, different from the conventional rapid activation protocol for Rapid Palatal Expander (RPE) or Mini-implant Assisted RPE. With its innovative design and unique biomechanical property of springiness coupled with the slow activation protocol inducing physiological sutural distraction osteogenesis, ATOZ™ may present a ground-breaking opportunity in enlarging the maxillary apical base without adverse effects for post-adolescents with craniofacial dysmorphism and reduce the need for complex craniofacial surgeries.</div></div>","PeriodicalId":48688,"journal":{"name":"Seminars in Orthodontics","volume":"31 2","pages":"Pages 240-251"},"PeriodicalIF":2.2,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141712165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bone Anchored Maxillary Protraction (BAMP) aims to correct the maxillomandibular deficiency for skeletal Class III patients in the middle or late stages of growth. The combination of mini-screw-assisted maxillary skeletal expansion (MARPE) with BAMP is the efficient solution for skeletal transverse and sagittal deficiencies, which aims to maximize skeletal effects while minimizing dental effects. This article presents a novel digital workflow for orthodontic treatment, focusing on mini-screw-assisted maxillary skeletal protraction following transverse expansion. The digital clinic workflow encompasses data acquisition, virtual design and planning, and 3D printing, which minimized the hands-on time of the dental laboratory as much as possible to improve efficiency. Additionally, the article provides a detailed description of the digital methodology for creating custom auxiliaries for maxillary protraction, including types and protocols of 3D printing auxiliaries.

The method involves strategically placing four mini-implants in the palate<span> before inserting the RPE screw. Subsequently, right and left bracket plates are fixed over the mini-implant heads to connect two anteroposterior mini-implants. The RPE screw is then attached to the bracket plates, securing the RPE connecting arms into 0.032 × 0.040-inch slot brackets on the bracket plates. The primary advantage of this method is that the RPE screw is replaceable and adjustable. This enhances the freedom in selecting mini-implant placement sites, ensuring better skeletal anchorage on the palatal bone compared to tooth-bone-borne RPE, where mini-implant placement sites are limited to the periphery of the RPE screw.
