3D printing, or additive manufacturing, is an evolving technology that enables the precise fabrication of customized orthodontic appliances by layering and curing photosensitive resin with a light source such as a laser. Its adoption is growing rapidly in orthodontic practices as it provides a more efficient and streamlined alternative to traditional techniques like dental impressions and plaster models. Although incorporating 3D printing into a digital workflow can present challenges—such as the need for specialized equipment and staff training—the advantages are substantial. These include greater accuracy, fewer errors, quicker production times, and long-term cost savings. When proper materials and standardized protocols are followed, 3D printing proves to be a reliable and effective tool for contemporary orthodontic care.
