Abstract: A device including one or more preformed or customized eruption guidance appliances placed in an individual's mouth. The preformed appliances are vibrated with a pulsation device to encourage tooth eruption by increasing the force and efficiency of the eruption toward a preferred location and a preferred alignment as well as providing increased blood flow and blood oxygen flow to the muscles and tissues in and around the oral cavity of the individual. The preformed guidance appliance driven by the pulsation device is selected from a range of guidance appliances, each of which is selected by size and shape to fit an individual based on the individuals anticipated tooth and jaw size as well as the growth profile.

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.
