Publication number: 20110159461Abstract: A power toothbrush (10) is disclosed having a handle (15), battery (12), ultrasonic drive circuit (14), motor (16), control unit (18), and toothbrush head (20). The toothbrush head includes bristles (26) and a waveguide (24) that is operatively connected to an ultrasonic transducer (22). The waveguide facilitates the transmission of acoustic energy into the dental fluid to achieve improved cleaning and stain removal and improved cleaning in interproximal and subgingival regions. In one embodiment an ultrasound transducer module (30) includes a plurality of piezoelectric elements (32, 34) that may be mechanically connected in series, and electrically connected in parallel. One or more contacts (36) connect the elements, and a waveguide structure (50). An impedance matching layer (38) may be provided between the waveguide and the ultrasonic transducer module. The waveguide may be formed from a relatively soft material, for example, a polymer having a hardness between 10 and 65 Shore A.Type: ApplicationFiled: March 14, 2011Publication date: June 30, 2011Applicants: WASHINGTON, UNIVERSITY OF, ULTREO, INC.Inventors: Pierre D. Mourad, James Christopher McInnes, George A. Barrett, David A. Ballard, Gerald K. Brewer, Frederick Jay Bennett

Patent number: 7448109Abstract: An oral hygiene device having an ultrasound transducer 22 and an acoustic waveguide 24 facilitating the transmission of ultrasonic acoustic energy to fluids in the oral cavity is disclosed. Preferred ultrasound operating parameters for operation in aqueous environments and in dental slurries are disclosed. Devices may incorporate a drive motor 16 for oscillating a device head 23, acoustic waveguide 24 and one or more bristle tuft(s) 26 at sonic frequencies, and preferred sonic operating parameters are also provided. Multi-element piezoelectric transducer assemblies 30, 40, and various control and communications features are disclosed. Oral hygiene devices 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, stimulating dental tissue, and disrupting biofilm.Type: GrantFiled: December 20, 2006Date of Patent: November 11, 2008Assignee: Ultreo, Inc.Inventors: Gerald K. Brewer, James Christopher McInnes, Daniel Bayeh, Frederick Jay Bennett, Richard K. Taylor, David A. Ballard, George A. Barrett

Publication number: 20080209650Abstract: Oral hygiene devices employing an ultrasound transducer are disclosed. The device is user-activatable to commence an operating cycle, and has a controller that may provide a timing function and may provide a variable level of ultrasound transducer output during an operating cycle. The controller may provide a monitoring function that is capable of detecting an ultrasound transducer fault condition and alert a user, through a user interface, when an ultrasound transducer fault condition is detected. The controller may be programmed to count the number of device operating cycles or accumulate the total device operating time and activate a transducer replacement signal following a predetermined number of uses or a predetermined accumulated operating time.Type: ApplicationFiled: February 22, 2008Publication date: September 4, 2008Applicant: ULTREO, INC.Inventors: Gerald K. Brewer, James Christopher McInnes, Daniel Bayeh, Frederick Jay Bennett, Richard K. Taylor, David A. Ballard, George A. Barrett, Marc W. Bommarito
