Abstract: A peeling type laser tooth preparing method, apparatus and device, and a medium. Method comprises: acquiring a first STL model of a target tooth and a second STL model of a tooth preparation of the target tooth; generating a conical peeling curved-surface STL model, in a manner of taking a three-dimensional curve of a peripheral edge contour of a shoulder in the second STL model as a bottom edge; carrying out Boolean calculation on the peeling curved-surface STL model and the first STL model to obtain a third STL model; carrying out Boolean calculation on the second STL model and the third STL model to obtain a fourth STL model required to be removed; generating a multilayer laser cutting path according to the fourth STL model, controlling a laser tooth preparing device to perform the tooth preparing process of the target tooth according to the multilayer laser cutting path.

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 (1).
