PATENT EXPIRED DUE TO NONPAYMENT OF MAINTENANCE FEES UNDER 37 CFR 1.362. Because the mass of handle 12 is so much greater than that of brush portion 14, and handle 12 is held in the hand of a user, the bristled end of brush portion 14 will vibrate about a greater radius (circles 38) than the handle 12 (circles 40). Because the device of this invention does not suffer from the disadvantages of the ultrasonically vibrating metal tip devices, it can safely be used a home as part of a person's every day routine of tooth brushing. Such devices can be uncomfortable due to the high intensity vibrations produced, which can cause nerve pain. Other prior art devices utilizing ultrasonics are U.S. Pat. It is preferred that a plaque softening or tooth polishing liquid or gel be applied to the teeth prior to use of the toothbrush. The ultrasonic transducer 48 is preferably a commercially available device capable of producing an ultrasonic wave in the frequency range of 10-20 MHz. 8. A further object of this invention is a toothbrush having a battery driven motor causing rotation of an eccentric member producing rotational vibration of the entire toothbrush, and an ultrasonic transducer coupled to the toothbrush which generates ultrasonic waves therein. FIG. Another object of this invention is a toothbrush that vibrates in a rotational manner, and which contains an ultrasonic transducer generating high frequency sound waves in the toothbrush in order to loosen plaque. No. The neck 24 of brush portion 14 may also be composed of plastic, and the neck 24 may have a metallic rod inserted therein to assist in the generation of high frequency sound waves therethrough as will be described. The ultrasonic waves are not focused and are general to the entire region about the brush in which the standing wave is produced. 3 is a diagrammatic view illustrating the vibration pattern of this invention; FIG. 2. The liquid or gel surrounding the teeth will respond to the ultrasonic energy by vibrating and producing cavitation, assisting in the loosening of the plaque and helping to carry it away from the teeth. The present invention provides a unique plaque removal device consisting of a toothbrush having an electric motor in the handle thereof causing rotation of an eccentric member which produces rotational vibration of the entire toothbrush. The removal of plaque is important to good dental health. Free format text: 3. What happens if you dont brush your teeth? In medicine, ultrasound has been used to examine organs without surgery, and has been found to be far safer than x-rays. An ultrasonic plaque removal device as in claim 4 in which said coupling means comprises: a) a holder having a rectangular shaped receptacle therein adapted to receive therein and hold securely the extension of said flat handle; and. It is therefore an object of this invention to produce a unique plaque removal device which comprises a vibrating toothbrush in combination with the generation and propagation of ultrasonic waves along the brush portion of the toothbrush. The ultrasonic energy, which is sufficient to cause vibration of brush portion 14 without overheating, is propagated as a moving wave in a non-focused manner throughout the mouth of the user. A device for removing plaque from teeth comprises a toothbrush having a thick, cylindrical, hollow handle in which are located an electric motor actuable to cause rotation of an eccentrically mounted member and vibration of the entire device, and an ultrasonic transducer actuable to produce high frequency sound waves along the brush. The combination of the rotational vibration of the brush and the production of the standing ultrasonic waves provides improved tooth cleaning capability. The combined action of the rotational vibration and the ultrasonic waves will be far more effective than brushing alone, or brushing combined with flossing, in loosening and removing plaque from teeth. Also in the handle is an ultrasonic transducer which produces ultrasonic waves that are coupled into the brush portion of the toothbrush and are propagated from the brush portion non-directionally in the mouth. Can You Remove Tartar Without Going To The Dentist? Dental care advice for people with disabilities, remove tartar instead of going to the dentist, remove tartar without going to the dentist, interdental brushes, floss or a water flosser here, https://www.youtube.com/watch?v=g4c2raUNKqc, Why its a bad idea to use products like these at home. c) second means located within said grip portion connected with and producing an ultrasonic wave within said brush portion. Earnings Disclosure & Privacy Policy.

The ultrasonic energy coupled into the brush portion 14 serves to soften or remove plaque from the teeth as the wave is propagated in the mouth. 4. in which a solid titanium wire is inserted into the artery of a human, and ultrasound vibrations are applied to the wire to produce a cavitation force for the removal of plaque from the artery. 3. b) wave transmitting means connecting said piezoelectric element to said holder whereby the ultrasonic waves are coupled from said piezoelectric element to said brush portion. Also connected to battery 20 is an electronics package 42 of standard construction producing high frequency oscillations which are coupled via lines 44,46 to an ultrasonic transducer 48. A still further object of this invention is a vibrating toothbrush in which an ultrasonic transducer generates high frequency sound waves to loosen plaque on the teeth.
