Optical Imaging: Capturing Every Detail of the Oral Cavity
The core of an intraoral scanner lies in its advanced optical imaging system. It rapidly captures high-resolution images of the oral cavity using miniature cameras and special light sources (such as blue light or lasers). These images not only clearly capture the shape of teeth and gums but also record subtle texture and color information. During the scan, the instrument continuously captures images at tens of frames per second, ensuring complete and uninterrupted data.
3D Modeling: The Magic from Plane to Solid
Point Cloud Generation: Each 2D image is converted into millions of spatial coordinate points.
Surface Reconstruction: Algorithms automatically connect adjacent points to construct triangular mesh surfaces.
Data Fusion: Multi-angle scan results are intelligently stitched together, eliminating overlaps and blind spots.
The entire process is like "sculpting" a precise replica of the patient's oral cavity with a digital paintbrush, achieving an accuracy of up to 20 micrometers.
Real-Time Interaction: Making Scanning Simple and Efficient
Modern intraoral scanners provide a "what you see is what you get" user experience. As the doctor moves the probe, the screen displays the 3D model generation process in real time, and the system provides sound or vibration alerts for incompletely covered areas. Some devices also have intelligent correction functions, which can automatically compensate for errors caused by slight patient movements, greatly improving clinical work efficiency.
