The present article describes the resin infiltration technique to address white spots lesions presented on anterior and premolar teeth of a young patient after orthodontic treatment and the digital workflow for planning a diastema closure on the maxillary anterior teeth using facial photographs, an intraoral scanner, a facially driven diagnostic waxing using a dental computer-aided design (CAD) software, and 3-piece additive manufactured (AM) clear silicone indices. The virtual design of the silicone indices was completed using an open-source CAD software and included a flexible clear buccal piece, flexible clear lingual piece, and rigid clear custom tray. The unique 3-piece index design allows a horizontal path of insertion, controlled uniform thickness of the indices, flexible and rigid material properties combination, accurate translation of the diagnostic waxing into the patient´s mouth, and digital storage of the designs.
本文介绍了一种树脂渗透技术，用于解决正畸治疗后前牙和前磨牙出现的白斑病损，以及使用面部照片、口内扫描仪、基于面部的 CAD 软件蜡型诊断、以及 3 件式增材制造（AM）透明硅橡胶指套来规划上颌前牙间隙关闭的数字化工作流程。硅橡胶指套的虚拟设计使用开源 CAD 软件完成，包括灵活的透明颊侧部分、灵活的透明舌侧部分和刚性透明定制托盘。独特的 3 件式指套设计允许水平插入路径、控制指套的均匀厚度、灵活和刚性材料特性的组合、准确地将诊断蜡型转化到患者口腔中，以及数字化设计的存储。
