Such devices can be uncomfortable due to the high intensity vibrations produced, which can cause nerve pain. The gums begin to pull away from the teeth and form pockets that may become infected. This results in considerably cleaner, plaque free teeth and prevents gum disease and bone loss. Earnings Disclosure & Privacy Policy.
2. 4 is a diagrammatic pictorial block diagram illustrating the internal components of this invention; and. An ultrasonic plaque removal device as in claim 5 and including an electrical battery located within said grip portion, and circuit means including a switch means connecting said battery with said electric motor and with said circuit means to provide electrical power thereto. Many prior art devices use ultrasound to remove plaque from teeth. 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. Cleaning is often accomplished by immersing the object into a cleaning liquid into which ultrasonic waves are propagated, with the cavitating liquid removing film or dirt even from inaccessible regions. An ultrasonic plaque removal device as in claim 7 in which said grip means has a removable end portion at the end opposite the said brush portion for providing access to said battery. 
5 is a cross sectional view along line 5--5 of FIG. 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 stickiness of the plaque keeps these acids in contact with teeth. Plaque is a thin, colorless, sticky film that constantly forms on the teeth. 
Bristles 26 are attached at one end of brush portion 14. After many such attacks, the enamel breaks down and a cavity forms. When foods containing sugars and starches are eaten, the bacteria in plaque produces acids which attack tooth enamel. Ultrasound has found wide industrial use, particularly in the nondestructive testing of manufactured objects and the cleaning of many objects. 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. FIG. 1 a toothbrush device 10 having a thick cylindrical hollow handle 12 to which is connected a removable brush portion 14. In addition to the ultrasonic loosening of the plaque, the brush vibration caused by the motor driven eccentric member 30 will, in conjunction with the polishing liquid or gel, also assist in removing or loosening plaque from the teeth. 1 is a diagrammatic perspective view of the present invention; FIG. 3. In U.S. Pat. 4,944,296 to Suyama incorporates a piezoelectric element into the handle of a toothbrush, the bending of the handle which occurs during normal tooth brushing causing the generation of electrons which remove that dental plaque which is charged with positive electricity. 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. If this gum disease is not treated promptly, the bone supporting the teeth is destroyed and healthy teeth may be lost. 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). Contained within the hollow center of handle 12 is an electric motor 28 to which is attached an eccentrically mounted member 30 via a rotatable shaft 32. Devices of this type are primarily dentist's tools and cannot be used at home. Other prior art devices utilizing ultrasonics are U.S. Pat. Ultrasonic sound wave vibrations above 20 KHz are generally produced by a transducer containing a piezoelectric or similar substance such as a quartz crystal oscillator which converts high frequency electric current to into vibrating ultrasonic waves. No. 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. They become swollen and may bleed. 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. Free format text: Commercially available units incorporate a solid metal tip to which appropriate ultrasonic energy is applied. PATENT EXPIRED DUE TO NONPAYMENT OF MAINTENANCE FEES UNDER 37 CFR 1.362. 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. 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.

Moving the member 16 to its other position turns the device 10 off. 5,013,241 to vonGutfeld et al., a dental tool is shown for cleaning plaque from teeth by focusing an ultrasound wave into a jet of liquid such as water which is then directed as a stream upon the teeth. The combination of the rotational vibration of the brush and the production of the standing ultrasonic waves provides improved tooth cleaning capability. Handle 12 has a removable end portion 18 which contains a replaceable battery 20. Can You Remove Tartar Without Going To The Dentist? If plaque is not removed by daily brushing, flossing or other techniques, it hardens into calculus (tartar).
This invention relates to an improved plaque removal device for teeth consisting of a toothbrush which vibrates and generates in the brush portion an ultrasonic wave to assist in loosening plaque. The combination of brush vibration and the propagation of ultrasonic waves in the mouth is considerably more efficient at removing plaque than brushing alone, or brushing and flossing. The outside case 22 of handle 12 is preferably of strong plastic to withstand hard use and being dropped on a bathroom floor. In accordance with a preferred embodiment of this invention where similar reference numerals denote similar elements throughout the drawings, there is shown in FIG. The energy is coupled directly from the transducer 48 through a connector 49 which acts as a wave guide and into holder 50 from which it propagates into the handle 24 of brush portion 14. No. The vibrating metal tip is used to contact the surface of a tooth in order to remove plaque therefrom. An ultrasonic plaque removal device as in claim 1 wherein said first means comprises an electric motor connected with and operable to produce rotation of an eccentric member. The use of separable components for device 10 permits each member of the family to use the invention and have their personal brush portion. Motor 28 will rotate eccentric member 30 and the entire device 10 will vibrate in a rotary direction as shown by the plurality of circles 38 in FIG. 6. FIG. 7. 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. c) coupling means for coupling said ultrasonic wave to said brush portion to produce ultrasonic vibration of said brush portion.
2. 4 is a diagrammatic pictorial block diagram illustrating the internal components of this invention; and. An ultrasonic plaque removal device as in claim 5 and including an electrical battery located within said grip portion, and circuit means including a switch means connecting said battery with said electric motor and with said circuit means to provide electrical power thereto. Many prior art devices use ultrasound to remove plaque from teeth. 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. Cleaning is often accomplished by immersing the object into a cleaning liquid into which ultrasonic waves are propagated, with the cavitating liquid removing film or dirt even from inaccessible regions. An ultrasonic plaque removal device as in claim 7 in which said grip means has a removable end portion at the end opposite the said brush portion for providing access to said battery. 5 is a cross sectional view along line 5--5 of FIG. 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 stickiness of the plaque keeps these acids in contact with teeth. Plaque is a thin, colorless, sticky film that constantly forms on the teeth. Bristles 26 are attached at one end of brush portion 14. After many such attacks, the enamel breaks down and a cavity forms. When foods containing sugars and starches are eaten, the bacteria in plaque produces acids which attack tooth enamel. Ultrasound has found wide industrial use, particularly in the nondestructive testing of manufactured objects and the cleaning of many objects. 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. FIG. 1 a toothbrush device 10 having a thick cylindrical hollow handle 12 to which is connected a removable brush portion 14. In addition to the ultrasonic loosening of the plaque, the brush vibration caused by the motor driven eccentric member 30 will, in conjunction with the polishing liquid or gel, also assist in removing or loosening plaque from the teeth. 1 is a diagrammatic perspective view of the present invention; FIG. 3. In U.S. Pat. 4,944,296 to Suyama incorporates a piezoelectric element into the handle of a toothbrush, the bending of the handle which occurs during normal tooth brushing causing the generation of electrons which remove that dental plaque which is charged with positive electricity. 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. If this gum disease is not treated promptly, the bone supporting the teeth is destroyed and healthy teeth may be lost. 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). Contained within the hollow center of handle 12 is an electric motor 28 to which is attached an eccentrically mounted member 30 via a rotatable shaft 32. Devices of this type are primarily dentist's tools and cannot be used at home. Other prior art devices utilizing ultrasonics are U.S. Pat. Ultrasonic sound wave vibrations above 20 KHz are generally produced by a transducer containing a piezoelectric or similar substance such as a quartz crystal oscillator which converts high frequency electric current to into vibrating ultrasonic waves. No. 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. They become swollen and may bleed. 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. Free format text: Commercially available units incorporate a solid metal tip to which appropriate ultrasonic energy is applied. PATENT EXPIRED DUE TO NONPAYMENT OF MAINTENANCE FEES UNDER 37 CFR 1.362. 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.

Moving the member 16 to its other position turns the device 10 off. 5,013,241 to vonGutfeld et al., a dental tool is shown for cleaning plaque from teeth by focusing an ultrasound wave into a jet of liquid such as water which is then directed as a stream upon the teeth. The combination of the rotational vibration of the brush and the production of the standing ultrasonic waves provides improved tooth cleaning capability. Handle 12 has a removable end portion 18 which contains a replaceable battery 20. Can You Remove Tartar Without Going To The Dentist? If plaque is not removed by daily brushing, flossing or other techniques, it hardens into calculus (tartar). This invention relates to an improved plaque removal device for teeth consisting of a toothbrush which vibrates and generates in the brush portion an ultrasonic wave to assist in loosening plaque. The combination of brush vibration and the propagation of ultrasonic waves in the mouth is considerably more efficient at removing plaque than brushing alone, or brushing and flossing. The outside case 22 of handle 12 is preferably of strong plastic to withstand hard use and being dropped on a bathroom floor. In accordance with a preferred embodiment of this invention where similar reference numerals denote similar elements throughout the drawings, there is shown in FIG. The energy is coupled directly from the transducer 48 through a connector 49 which acts as a wave guide and into holder 50 from which it propagates into the handle 24 of brush portion 14. No. The vibrating metal tip is used to contact the surface of a tooth in order to remove plaque therefrom. An ultrasonic plaque removal device as in claim 1 wherein said first means comprises an electric motor connected with and operable to produce rotation of an eccentric member. The use of separable components for device 10 permits each member of the family to use the invention and have their personal brush portion. Motor 28 will rotate eccentric member 30 and the entire device 10 will vibrate in a rotary direction as shown by the plurality of circles 38 in FIG. 6. FIG. 7. 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. c) coupling means for coupling said ultrasonic wave to said brush portion to produce ultrasonic vibration of said brush portion.
