  • Patent number: 8978189
    Abstract: The inventive device object of the present application is an innovative automatic toothbrush that fits like a mouth guard between the user's top and bottom teeth. Moving bristles will clean all around each tooth at the same time, so teeth can be cleaned well and in less time than using a conventional toothbrush. Omnibrush is a revolutionary new way to have enhanced dental care. It fits around the top and bottom teeth like a mouth guard. There are bristles for the outside, the inside and the tops and bottoms of each individual tooth. While positioned comfortably within the mouth, the bristles will work automatically to clean every tooth thoroughly. The unit is electrically powered, using a charger or rechargeable batteries. The cleaning bristles can be replaced when they become worn, eliminating the need to replace the whole cleaning unit. It will be available in a small size so children can use it as well.

  • Patent number: 8516642
    Abstract: The curved-head electric toothbrush includes an elongate housing having a drive assembly contained therein. The housing provides a handle portion and a tapering section that holds a curved brush mount. The curved brush mount has a plurality of rotatable brush units mounted thereon. The brush mount is shaped to conform to the curved row of teeth of a user's mouth. The drive assembly drives one of the brush units, and the rest of the brush units are driven by the driving brush unit so that adjacent brush units rotate in opposite directions. Each brush unit includes curved, outer bristles and straight, inner bristles, the former for cleaning the outer side surfaces and the latter for the top surface of teeth. In use, the curved-head electric toothbrush simultaneously cleans substantially the whole row of teeth with minimal manual manipulation.

  • Patent number: 8434183
    Abstract: A brush section for use with an electric toothbrush includes a movable contact element holder and a fixed contact element holder. The movable contact element holder is driven to move relative to the fixed contact element holder by an electric drive in a handle section which is coupled to the movable contact element holder. The risk of oral mucosa being pinched by the movement is minimized by any one of several methods, such as for example reducing the width of the gap between the two holders, adding a cover member, reducing the movement of the movable contact element holder, and the like. In addition, a low profile brush section is provided.
