    • A power toothbrush (10) is disclosed having a handle (15) containing a rechargeable battery (12), an ultrasonic drive circuit (14), a sonic component (16) such as a motor, and a control unit (18). The handle is connected to a toothbrush head (20) preferably having a plurality of bristles (26) and an ultrasonic transducer (22) that is operatively connected to a waveguide (24) that extends from the toothbrush head generally adjacent the bristles. The waveguide facilitates the transmission of acoustic energy into the dental fluid. It is contemplated that the waveguide may be utilized in manual or power toothbrushes, and in a combination without the sonic component, or in a combination without the ultrasonic transducer. Toothbrushes disclosed herein achieve improved plaque and stain removal from the teeth as well as interproximal and subgingival regions, while enhancing the user experience, massaging the gums, and stimulating dental tissue.
    • 公开了一种电动牙刷(10),其具有包含可再充电电池(12)的手柄(15),超声波驱动电路(14),诸如电动机的声音部件(16)和控制单元(18)。 手柄连接到优选地具有多个刷毛(26)的牙刷头(20)和可操作地连接到从牙刷头大致相邻于刷毛延伸的波导(24)的超声波换能器(22)。 波导有助于将声能传输到牙科液体中。 可以想到,波导可以用于手动或动力牙刷,并且在没有声音部件的情况下组合,或者在没有超声换能器的情况下组合。 本文公开的牙刷实现了从牙齿以及邻间和龈下区域改进的斑块和污渍去除,同时增强了使用者体验,按摩牙龈和刺激牙齿组织。
