3D Printing In Orthodontics- A Review

AbstractThe integration of 3D printing technology into orthodontics has revolutionized treatment planning and appliance fabrication processes. This paper reviews the current applications, benefits, and limitations of 3D printing in orthodontic practice. From the production of custom aligners and indirect bonding trays to the creation of precise orthodontic models and surgical guides, 3D printing enhances treatment accuracy, efficiency, and patient comfort. Various printing technologies such as stereolithography (SLA), fused deposition modeling (FDM), and selective laser sintering (SLS) are discussed in terms of their relevance and suitability for specific orthodontic applications. Furthermore, this review highlights ongoing research, material advancements, and the potential future role of fully digital orthodontic workflows.Despite certain challenges related to cost, regulatory standards, and material bio-compatibility, 3D printing continues to drive significant innovation in the field, pointing toward a more customized and patient centric approach in orthodontic care.Key words - Aligners, Orthodontic retainers, 3D printing
