1. An automated orthodontic bracket positioning system, comprising:
a computer system, configured for constructing a digital 3D dental model, and the computer system predicting positions of orthodontic brackets on patient's tooth surface based upon the 3D dental model; an automatic bracket positioning device, coupled with the computer system and controlled by the computer system; the automatic bracket positioning device comprising a multi-joint robotic arm capable of performing a multi-angle, multi-axle, and multi-curvature movement; a holder disposed at a distal toggle of the multi-joint robotic arm to hold or release a bracket; a bite record device, coupled with the computer system, and comprising a bite recorder and a sensor; the bite recorder comprising a tray for being bitten by the patient's upper and lower dentitions, and at least two calibrating markers disposed on the tray; the sensor mounting on the automatic bracket positioning device and configured for detecting the calibrating markers and transmitting a detected message to the computer system; the computer system executing a program computation to convert the detected message of the bite record device to an intra-oral coordinate record, and then using the intra-oral coordinate record to calibrate the digital 3D dental model, to ensure that the predicted position of the bracket accurately match with the patient's tooth surface, the automatic bracket positioning device connected with the bite recorder and transferring bracket onto the patient's tooth surface according to the predicted position; and a light emitting module, disposed at the remote toggle of the multi joint robotic arm, the light emitting module configured for providing a curing light to harden light-curing adhesive on the bracket held by the holder and positioned on the patient's tooth surface. |
