An intraoral scanner is a portable device used to directly create digital imprint data of the oral cavity. The scanning software interprets the data to build a real-time 3D model that is displayed on a touch screen by projecting light onto scan objects, such as complete dental arches. This produces high-quality photos with accurate details of the hard and soft tissues of the mouth.These intraoral scanners operate using non-invasive optical technologies such as confocal microscopy, light triangulation, and active sampling wavefront, typically combined for intraoral use. They capture light projection as individual images or video, compiling them via software to reconstruct 3D models accurately. In addition, they facilitate treatment planning and orthodontic diagnosis and also provide quick electronic data transfer, which lowers the need for storage space.
