  • Patent number: 7806689
    Abstract: The present invention relates to a disposable dental instrument used by dental professionals to polish a patient's teeth. The dental instrument can be connected to a hand motor used to rotate a prophy cup with a plurality of grinding wings that rub against the patient's teeth as a predetermined amount of tooth cleaning fluid is discharged directly on the patient's teeth through a drain hole within the prophy cup. The tooth cleaning fluid is discharged from a tube that is assembled in a tube room of the dental instrument. The tube is a flexible bladder similar in function and form to a tube of toothpaste. The tube is made of a flexible polymer material that allows it to be squeezed when pressure is applied to it. A roller is assembled within the tube room and on top of the tube. As the roller is pushed forward with a finger, the tube is squeezed to discharge the tooth cleaning fluid directly on the patient's teeth.

  • Patent number: 7510396
    Abstract: The present invention relates to a hand tool used by dental professionals to polish a patient's tooth. The hand tool can be connected to a hand motor used to rotate a wheel cup with a plurality of grinding wings that rub against the patient's tooth as a predetermined amount of dentifrice material is discharged directly on the patient's tooth through a drain hole within the wheel cup. The dentifrice material is discharged from a tube that is assembled in the housing of the hand tool. The tube has a plurality of folds formed on the tube body in such a manner as to be folded by a given distance while being compressed to discharge the dentifrice material therefrom. The tube is compressed by a link with a push button that is guided in the forward direction as it is pushed by a finger.
