An intraoral scanner is a digital data acquisition device used in the field of oral medicine. Its core principle is optical 3D reconstruction technology-high-resolution blue or white structured light is projected onto the tooth surface, and multi-angle cameras simultaneously capture the reflected patterns. Algorithms then calculate millions of spatial coordinate points in real time to generate a precise 3D model of the dental arch.
This technology eliminates the need for traditional silicone impressions, avoiding patient nausea and swallowing discomfort, and also avoids errors caused by impression material deformation. It has become a crucial front-end step in the digital orthodontic, restorative, and implant workflow.
