Intraoral scanners capture optical data from teeth and oral structures to create digital three-dimensional surface models. During scanning, a handheld scanner projects light onto the target area, records successive images or surface data, and software aligns the information into a digital impression. Scan strategy, field coverage, tip size, calibration, and software processing can influence the resulting dataset. Digital files may be used in restorative, orthodontic, implant, or laboratory workflows when supported by the system. This category includes wired and wireless scanners with model-dependent software and accessories.
