Abstract

A digital control laser automatic tooth preparation method and device and a tooth positioner are provided. The device includes an intra-oral three-dimensional scanner, a dental laser, an oral working end, an oral and maxillofacial cone beam CT scanner, a computer, a tooth positioner, a negative-pressure suction device and a real-time monitoring device. The computer is connected respectively with the intra-oral three-dimensional scanner, the dental laser, the oral working end, the oral and maxillofacial cone beam CT scanner, the negative-pressure suction device, and the real-time monitoring device. The dental laser is connected with the oral working end of the digital control laser tooth preparation control system through a light guiding arm (). The oral working end of the digital control laser tooth preparation control system is connected with the tooth positioner and the real-time monitoring device. The negative-pressure suction device is connected with the tooth positioner.
