  • Training method for evaluating bonding accuracy of orthodontic brackets
    Patent number: 11657733
    Abstract: A training method for evaluating the bonding accuracy of orthodontic brackets is provided. The evaluation method includes a training device for racket bonding accuracy evaluation which includes virtual teeth with root-shaped connectors and an evaluation base to fix the virtual teeth. Multiple reference lines are marked on the evaluation base, and their intersection is set as the evaluation point. When the virtual tooth is fixed to the evaluation base, the reference lines and the evaluation points are utilized for rapid evaluation of the bonding accuracy of the bracket. Moreover, thanks to their horizontal arrangement, when there are multiple virtual teeth, the evaluation of bracket bonding would be more intuitive and efficient than using the traditional articulator.
