An intraoral scanner (IOS) is a device that uses light or laser technology to capture thousands of tiny images per second, thereby creating an accurate 3D model of teeth and gums. This device completely replaces traditional physical impression taking, and is used in the design of dental crowns, aligners, and surgical trays on a computer with micron.

In a digital dental clinic, Intraoral Scanner (IOS) and CBCT two mandatory pieces of equipment.

Here is the detailed comparison of why digital scanning is the superior choice today:

  • The scanner uses a small, sleek wand that “photographs” your teeth. There is no mess, no bad taste, and most importantly, no gag reflex
  • Pause and Resume: If a patient needs a break, the dentist can simply stop the scan and resume exactly where they left off—something impossible with traditional materials.
  • Intraoral scanners capture data with micron-level precision. The 3D model is a perfect digital twin of your mouth
  • Real-Time Validation: The software alerts the dentist instantly if a spot was missed, ensuring the “perfect fit” for crowns, veneers, or aligners on the very first try
  • Many clinics use an integrated CAD/CAM system. This means your teeth are scanned, the crown is designed, and it’s milled in-office—allowing you to walk out with a permanent restoration in just one hour
