Structured-light intraoral scanners require the projection of precise light patterns onto the tooth surface. DLP (Digital Light Processing) technology

ICP (Iterative Closest Point) is the most classic algorithm in the field of 3D point-cloud registration and forms one of the technical foundations for

Calibration is the process of determining the camera's intrinsic and extrinsic parameters, correcting optical distortion, and establishing a measureme

Colored 3D models contain significantly more clinical information than monochrome models. Texture mapping is the key technology that enables true-colo

The handle of an intraoral scanner generates heat during continuous operation. Heat dissipation design not only influences grip comfort but also direc

Raw scan data inevitably contains noise. Filtering and smoothing algorithms are essential steps that ensure the quality of the final 3D model. Sources

Although the scanning tip of an intraoral scanner is only the size of a finger, it houses a complex optical lens system. The design and manufacturing

Active Wavefront Sampling is the patented imaging technology used in the 3Shape TRIOS series. It is a key enabler of real-time color video scanning. T

Confocal microscopy is the core imaging technology of the iTero series intraoral scanners, renowned for its exceptionally high single-point accuracy.

Active triangulation is the most fundamental and widely used 3D measurement principle in intraoral scanners. Structured light and laser line scanning

When a thin film of saliva covers the enamel surface, strong specular reflection (glare) occurs. This glare prevents optical sensors from accurately c

The real-time 3D tooth model that appears on the intraoral scanner screen looks simple, yet it is the result of a sophisticated data-processing pipeli
