A 3D intraoral digital scan is a modern dental imaging technique that captures a highly accurate, three-dimensional image of a patient’s teeth, gums, and bite using a small handheld device called an intraoral scanner.
How It Works
Scanning:
The dentist or dental assistant moves the scanner around the patient’s mouth.
It uses optical or laser technology to capture thousands of images per second.
Image Processing:
The software instantly stitches these images together to create a 3D digital model of the oral cavity.
Visualization:
The model can be viewed in real-time on a screen, rotated, zoomed, and analyzed for accuracy.
Uses
Digital impressions for crowns, bridges, veneers, and aligners
Implant planning and surgical guides
Orthodontic assessment and aligner fabrication
Monitoring oral changes over time (wear, gum recession, etc.)
Patient education — helps patients visualize their treatment needs.
Advantages
No messy impression materials (more comfort for patients)
High accuracy and fewer remakes
Fast turnaround for labs and digital workflows
Better communication between dentist, lab, and patient
Digital record keeping and easy comparison over time.
