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 of a digital control laser tooth preparation control system, 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 of the digital control laser tooth preparation control system, 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. The digital control laser automatic tooth preparation method and device according to embodiments of the present invention can replace part of manual operations of a doctor, uses a laser to replace a conventional mechanical grinding instrument, and can effectively improve the standard level and efficiency of clinical oral tooth preparation.
