Face scanners capture a patient's three-dimensional facial anatomy, including lip dynamics, smile line, and midline, to integrate with intraoral scan and CAD design data for digital smile design and esthetic treatment planning. By overlaying facial and dental data, clinicians and technicians can design restorations, veneers, and full-arch prostheses proportioned to the patient's face and smile rather than the dental arch alone. Face scanning is increasingly used in complex esthetic and full-mouth rehabilitation cases, implant-supported prosthetic planning, and orthodontic treatment planning, forming an added data layer in the modern digital workflow.
