DENTAL ULTRASONIC CLEANING DEVICE AND METHOD FOR CLEANING TEETH OR DENTURES BY USING ULTRASONIC WAVES

摘要

Provided is a dental ultrasonic cleaning device that efficiently cleans teeth or dentures in an oral cavity using ultrasonic waves. A dental ultrasonic cleaning device 1 emits ultrasonic waves through a cleaning-liquid (W1) to the surface of a cleaning-target 26, ultrasonically cleaning it. An ultrasonic born 24 propagates ultrasonic waves being generated by an ultrasonic-wave transducer 23 and emits them from the vibratory surface 25 provided at the tip-end of the horn 24. A liquid-reserving part 27 is provided, surrounding the vibratory surface 25 of the ultrasonic horn 24, which temporarily reserves the cleaning-liquid (W1) between the vibratory surface 25 and the cleaning-target 26. A cap-member 33 is provided at a certain interval opposite the liquid-reserving part 27. A cleaning-liquid discharge-tube inlet 35 is connected to a vacuum tube 36 within the cap-member 33, allowing the cleaning-liquid W1 used during the ultrasonic cleaning to be vacuumed from the oral cavity, into the cap-member 33, and then discharged through the vacuum tube 36.

主权项

1. A dental ultrasonic cleaning device for cleaning the teeth or dentures ultrasonically by emitting ultrasonic waves through a cleaning-liquid to a cleaning-target, such as a surface of teeth or dentures in an oral cavity, which is characterized by an ultrasonic-wave transducer for generating the ultrasonic waves; by an ultrasonic-wave propagating unit for propagating the ultrasonic waves to an ultrasonic-wave emitting surface at a tip-end side of the ultrasonic-wave propagating unit; by a liquid-reservoir part for temporarily reserving the cleaning-liquid between a surface of the cleaning-target and the ultrasonic-wave emitting surface in a state of being in contact with the cleaning target, the liquid-reservoir part being provided in such a manner as to surround the ultrasonic-wave emitting surface; by a liquid-supply tube for supplying the cleaning-liquid to the liquid-reservoir part; by a suction tube having a liquid-suction part and for sucking and draining the cleaning-liquid that had been used during the ultrasonic cleaning through the liquid-suction part, the liquid-suction part being disposed at a predetermined distance from the liquid reservoir part.
