With the advancement of 3-dimensionally (3D) printing technology, orthodontists can design and fabricate 3D-printed indirect bonding trays and transfer jigs for lingual brackets independently from the laboratory. The present article describes, in detail, the digital workflows for designing and fabricating 3D-printed lingual bracket indirect bonding trays and transfer jigs. Additionally, it aims to demonstrate the effectiveness of this approach in managing common orthodontic issues in adult patients. The first case report exemplifies the successful management of moderate crowding in a Class I adult patient using a non-extraction approach with lingual brackets and flexible 3D-printed indirect bonding trays. The second case illustrates the application of lingual brackets and rigid 3D-printed indirect bonding trays in managing a skeletal Class II adult patient with mouth protrusion requiring four-bicuspid extractions. The achieved good treatment results might demonstrate the high transfer accuracy of 3D-printed lingual bracket indirect bonding trays. Additional studies with large sample sizes should be conducted to compare the effectiveness and efficiency of 3D-printed trays with other tray types.
随着三维(3D)打印技术的进步,正畸医生可以独立于实验室设计和制作用于舌侧托槽的3D打印间接粘接托盘和转移夹具。本文详细描述了设计和制作3D打印舌侧托槽间接粘接托盘及转移夹具的数字工作流程。此外,旨在证明该方法在处理成年患者常见正畸问题方面的有效性。第一例病例报告展示了一名I类成年患者使用舌侧托槽和灵活的3D打印间接粘接托盘,采用非拔牙方法成功矫治中度牙列拥挤。第二例病例说明了舌侧托槽和刚性3D打印间接粘接托盘在治疗一名需要拔除四颗双尖牙的骨性II类成年突嘴患者中的应用。所取得的良好治疗效果可能证明了3D打印舌侧托槽间接粘接托盘的高转移精度。应进行更多大样本量的研究,以比较3D打印托盘与其他类型托盘的有效性和效率。
