Novel laser scanning system for digital dental

Abstract

A novel laser scanning system is established for digital dental CAD/CAM. The system structure, kinematic model and calibration method are described in detail. The system integrates advanced motor control technology, laser scanning technology, and data processing technology. Based on the principle of laser triangulation, mechanical and electronic technologies, the surface of dental wax can be scanned without any blind point. Experiment shows that the scanning precision of the system is 0.18mm, scanning speed is 8 000 pts/s, 3D model of the dental wax can be reconstructed conveniently.
