  • Patent number: 10123860
    Abstract: A method employs a closed system mouthpiece using light and heat generation to activate a gel formulation to increase its volume. The gel formulation is coated into the mouthpiece, which is inserted into the user's mouth. Application of heat above a threshold temperature causes the gel to transform into foam and expand out of the mouthpiece and into the oral cavity. The mouthpiece creates a hermetic seal such that the foam expands out throughout the oral cavity into nooks and crannies that are normally difficult to access. Activation of a light source embedded within the mouthpiece enhances the bacteria killing properties of the foam material. The pH balance of the mouth is restored by the inventive method and apparatus to a neutral level in the range of 6.75 to 7.25.

  • Patent number: 8585404
    Abstract: Efficiency-modulated ultrasonic dental inserts (12) are disclosed for preventing the overpowering of power-sensitive tips (18). The inserts (12) are useful in a handpiece (10) having an induction coil (20) disposed about a well and operable with an adjustable power supply having a maximum power output setting. An efficiency-modulated magnetostrictive element (14) is adapted to be received in the well. A velocity transducer (16) has proximal and distal ends. The proximal end is attached to a distal end of the magnetostrictive element (14). A power-sensitive tip (18) has a proximal end secured to the distal end of the velocity transducer (16). The efficiency of the magnetostrictive element (14) is matched with the power range of the tip (18) to prevent overpowering the tip (18) at the maximum power output setting.

  • Publication number: 20130273498
    Abstract: A dental implant comprising an implant body which has an asymmetric root portion receivable in an asymmetric open root cavity of the patient and engagement means on the asymmetric root portion to at least in part engage a surface of the root cavity so as to prevent or inhibit unintentional extraction. The asymmetric root portion is complementarily shaped to fit the said asymmetric open root cavity, thus substantially dispensing with the need for protracted preparation of the root cavity and providing substantially immediate stability for the prosthetic tooth.

  • Publication number: 20130122458
    Abstract: A system and a method for detecting irregular bone defects during dental implant osseointegration process. The system comprises a detecting abutment, an ultrasonic driver, a signal receiving and analyzing device. When dental detection is performed, the detecting abutment is disposed on a substrate holder of a dental implant. The ultrasonic driver configures the piezoelectric transducers disposed on the detecting abutment to produce ultrasonic wave and transmits the ultrasonic wave to the contact surface between the dental implant and the alveolus bone. The piezoelectric transducers can receive the reflected wave caused by the each portion of the contact surface reflecting the ultrasonic wave and transform the reflected wave into time domain voltage signal. The signal receiving and analyzing device receives the time domain voltage signal to determine the depth, the severity and the location of the irregular bone defects of the contact surface.

  • Patent number: 8435034
    Abstract: The present invention describes an ultrasonic dental insert capable of enhanced operating efficiency. A first transducer generates ultrasonic vibrations. A connecting body has a proximal end and a distal end having a tip attached thereto. The proximal end is attached to the first transducer so as to receive the ultrasonic vibrations therefrom and to transmit the ultrasonic vibrations toward the tip attached to the distal end. The ultrasonic dental insert may be inserted into a handpiece for providing electromagnetic energy to the first transducer to generate the ultrasonic vibrations. The ultrasonic insert, when seated in the handpiece, is substantially decoupled, on a rotary axis, from the handpiece. A rotary force need only be applied to the insert to rotate it in the handpiece. At least one light source substantially proximate or distal to the tip may also be provided.
