Jaw correction system and monitoring method

The invention discloses a jaw correction system and a monitoring method. The system comprises an extraoral anchorage, a tractor, a positioning system and a wearing information collection subsystem, during a correction treatment course, the positioning system can collect positioning data of extraoral anchorage, a forehead pad, a lower jaw pad and a fixing screw after the tractor is adjusted each time, corresponding positioning data sequences are generated respectively, stress and force attenuation of each monitoring point in different periods can be obtained through the wearing information collection subsystem, and a mechanical data sequence is formed. According to the technical scheme provided by the invention, the wearing duration and the stress magnitude and direction of each monitoring point can be displayed in real time; the correction effect of the child patient can be evaluated according to the positioning data sequence and the mechanical data sequence, so that medical staff can adjust the height positi
