The result? A highly accurate, digital 3D model of your mouth.

The Magic Behind the Scan

The technology behind intraoral scanners is quite impressive. Here's a simplified breakdown:

1. Light Source: The scanner projects a light source (either a laser or structured light) onto the oral tissues.
2. Image Capture: Multiple images are captured by the scanner as it moves around the mouth.
3. Data Processing: Sophisticated software stitches these images together to create a comprehensive 3D model.
4. Digital Model: The final product is a digital impression that can be used for various dental applications.

The beauty of this process is that it's quick, precise, and much more comfortable for patients compared to traditional methods. No more messy impressions!
