The present invention is to provide an ultrasound tip for cortical resection in order to reduce the period of orthodontic treatment for improving the removing efficiency in cortical resection for large-scale tooth movement and, moreover, for supplying cooling fluid effectively to an area where ultrasonic stimulation is given. For this, the present invention is the ultrasound tip comprising a body part stretched between a proximal part mechanically connected to a hand piece for operation generating ultrasonic vibrations, and a distal part made to reproduce the ultrasonic vibrations forwarded by the hand piece, which comprises a sawtooth head where at least more than two rows of sawteeth are formed on the distal part of the body, an exhalant opening discharging the cooling fluid between each row of the sawtooth head, and an inner fluid pipe line installed between the proximal part and the exhalant opening inside the body part. |
