Intraoral scanners are handheld optical devices that capture a direct digital impression of a patient's teeth and soft tissues, replacing conventional impression materials and trays. The resulting 3D scan data feeds directly into CAD software for restoration design, streamlines communication with the laboratory, and can integrate with face scan and CBCT data for comprehensive digital treatment planning. Intraoral scanning improves patient comfort, reduces impression-related remakes, and shortens turnaround time between clinical data capture and laboratory fabrication, making it a foundational entry point into the modern digital dental workflow.
