    摘要： A device for accelerating tooth movement under orthodontic treatment is disclosed. The device includes a vibrational source and a patient-specific tray. The device applies vibrational forces with prescribed frequency and intensity to the teeth under orthodontic treatment with traditional appliances, such as bracket-wire system or aligner. The patient-specific tray ensures the vibrational stimulations on the teeth to be moved. The level of stimulation intensity can be controlled by varying the preload on each of the teeth based on the clinician's prescription. The tray can be further modified to ensure continuous delivery of the desired vibrational forces on the teeth when they move during the treatment.
