Abstract：
Successful closure of edentulous spaces with clear aligners (CAs) is influenced by many factors. CAs are tailored orthodontic devices whose predictability may have relevant medico-legal implications. This study presents a scoping review about missing molar space closure (MMSC) with CAs and a clinical case. This study aims to highlight the feasibility of molar space closure by mesialization with CAs without hybrid supports. Following PRISMA Sc-review guidelines, English-written randomized/non-randomized/observational clinical studies on PubMed, Scopus, Cochrane and Lilacs were searched. An 18-year-old patient, with upper and lower edentulous spaces due to the loss of two first molars, was rehabilitated with CAs (Sorridi®, Sorridi srl, Latina, Italy) without hybrid supports and attachments. The therapy was carried out over 10 months. Currently, there are no studies documenting MMSC by mesialization with only CAs. Existing articles document the closure of premolar or incisor spaces. The upper and lower left second molars replaced the missing first molars, and erupting third molars replaced adjacent teeth. The biomechanical effects in space closure with CAs related to extraction cases appear as priorities of clinical/medico-legal interest. Our case turns attention to this movement of CAs without attachments/hybrid supports, indicating that even such a complex treatment can be comfortable for patients and safely predictable for specialists.
摘要：
使用清晰的矫正器（CA）成功闭合无牙空间受许多因素的影响。CA是量身定制的正畸设备，其可预测性可能具有相关的医学法律意义。这项研究提供了有关CAs缺失磨牙空间闭合（MMSC）和临床病例的范围审查。这项研究旨在强调通过在没有混合支撑的情况下与CA进行中间化来闭合磨牙空间的可行性。遵循PRISMASc审查指南，PubMed上的英语编写的随机/非随机/观察性临床研究，Scopus,搜索了科克伦和丁香花。一个18岁的病人,由于失去了两个第一磨牙，上下缺牙空间，被CA修复(Sorridi®，Sorridisrl,Latina,意大利）没有混合支架和附件。治疗进行了10个月。目前,没有通过仅CA的中介化记录MMSC的研究。现有的文章记录了前磨牙或门牙空间的闭合。左上和左下第二磨牙取代了丢失的第一磨牙，爆发的第三磨牙取代了相邻的牙齿。与拔牙有关的CA在空间闭合中的生物力学作用似乎是临床/医学法律利益的优先事项。我们的案例将注意力转向没有附件/混合支撑的CA的这种运动，这表明，即使是这样一个复杂的治疗可以舒适的病人和安全可预测的专家。
