Lingual orthodontics provides a highly esthetic treatment alternative but remains technically demanding due to limited access, complex lingual tooth morphology, and sensitivity to appliance positioning. Traditionally, successful lingual treatment has depended on meticulous manual set-up procedures and indirect bonding protocols, which are highly operator-dependent and prone to variability. In recent years, the integration of digital technologies has fundamentally transformed lingual orthodontic workflows. Three-dimensional digital set-up models enable precise visualization and planning of tooth movements, while virtual bracket positioning improves accuracy and reproducibility of appliance placement. Furthermore, CAD/CAM-designed lingual bracket systems introduce individualized bracket bases and customized archwires, allowing enhanced force control, reduced chair time, and improved treatment efficiency compared with conventional prefabricated lingual appliances. Customized archwire design based on digital treatment planning further contributes to predictable tooth movement and minimizes the need for manual adjustments. This review summarizes the evolution from traditional lingual set-up concepts to contemporary digital workflows, critically discusses the advantages and limitations of digital set-up and CAD/CAM-designed lingual systems, and highlights their current clinical applications. Despite higher initial costs and technical requirements, digital technologies have significantly enhanced precision, comfort, and predictability in modern lingual orthodontic treatment.
