System and method for realizing automatic air cutting of dental handpiece under navigation technology

The invention discloses a system for realizing the automatic air cutting of a dental handpiece under a navigation technology. The system comprises a navigator, a computer, a relay controller, a pneumatic solenoid valve, an air compressor and a dental handpiece. When the system works, the computer reads the state of the navigator in real time; when the navigator captures errors of the dental handpiece or a jaw position, the relay controller is controlled to carry out power supply; and the relay controller controls the pneumatic solenoid valve through a control panel to make the pneumatic solenoid valve carry out air cutting off, so that an air supply channel through which the air compressor supplies air for the dental handpiece is cut off, and therefore, automatic air cutting is realized, and the dental handpiece stops rotating. According to the system and method for realizing the automatic air cutting of the dental handpiece under the navigation technology provided by the invention, the state of the navigator
