  • Patent number: 5336708
    Abstract: Novel composites are formed from a low rigidity gelatinous elastomer composition of poly(styrene-ethylene-butylene-styrene) triblock copolymer and high levels of a plasticizing oil. The gelatinous elastomer composition is physically interlocked with an open cell sponge thereby displacing the air space within the sponge and the gel rigidity is found to be greater than about the sum of the combined rigidity of the gelatinous elastomer composition and sponge alone. The gelatinous elastomer composite exhibits a novel combination of properties including unexpectedly high elongation and tensile strength and excellent shape retention after extreme deformation under high-velocity impact and stress conditions. The gelatinous elastomer composites can be made firm or soft and flexible.

  • Patent number: 5334646
    Abstract: Novel gelatinous compositions and articles are formed from an intimate melt blend admixture of poly(styrene-ethylene-butylene-styrene) triblock copolymer and high levels of a plasticizing oil.The gelatinous composition is transparent and have a novel combination of properties including unexpectedly high elongation and tensile strength and excellent shape retention after extreme deformation under high-velocity impact and stress conditions. The gelatinous products of this invention are soft, flexible, and have elastic memory, characterized by a gel rigidity of from about 20 gram to about 700 gram Bloom. These and other properties are particularly essential for the gelatinous composition to have utility as toys, therapeutic hand exercising grips, shock absorbers, acoustical isolators, components for cushions, and other uses.

  • Patent number: 5333346
    Abstract: An interdental toothbrush has a hinged locking retainer on the end of an elongated handle. The locking retainer has a hole which is positioned relative to a groove in the handle so that a twisted wire brush may be locked into place simply by inserting it and closing the retainer. A latch on the locking retainer has a top end with a double cam surface thereon. One of the cam surfaces guides the latch into a locking position as the retainer is closed. The other of the cam surfaces releases the locking retainer when pushed.

  • Patent number: 5330357
    Abstract: A method of and system for the treatment of periodontal diseases is disclosed wherein a patient, using a delivery device, applies a medicament directly to the infected site. The delivery device may comprise a piece of tufted dental floss, an interdental brush, a syringe, or a night time application tray for forcibly applying medicament to the infected site. The delivery device carries a supply of an antimicrobial or antibiotic medicament, preferably a tetracycline, dichloride or hydrogen peroxide solution or gel. By flossing, brushing, injecting, or by forcibly disbursing the medicament with the delivery device, the patient can apply the medicament directly on or in close proximity to the infected site (i.e., bony support structure of the teeth). The medicament (tetracycline) bonds with the bony structure to promote bone regeneration, decrease osteoclastic activity and to allow osteoblastic activity to continue with a consequent decrease in bone loss rate while promoting bone growth (regeneration).

    Abstract: An integrally formed dental floss and leader which lends itself to oral prophylaxis especially for implants and bridges. The floss is captured by the leader through a hinged door which swings from an open to a closed position during fabrication to provide an integral unit for use by a floss user when closed. A leading portion of the door fits flush within a complementally formed support channel within a tethered end of the leader. A trailing portion of the door projects with an extension of a floor of the support channel, defining a tongue, to provide a floss support. A hinge defines a transition between the floor extension and the door. The hinge allows the door to pivot about the floss and enter the support channel with the floss interposed between the door and the tongue. Shoulders border the support channel providing reinforcement to the tethered end.

    Abstract: A toothbrush comprising a floss bundle primary cleaning element instead of conventional bristles. The floss bundle, having no sharp tips, can clean, absorb and polish without risk of cutting gums. No toothpaste is required. Because of the soft, smooth nature of the floss bundle, the invention can be used dry as well as wet, and, thus, function safely and properly where no water is available. This floss bundle is held in a clamp, having upper and lower jaws, fixed at one end of a handle. The lower jaw comprises a sleeve which encircles a threaded bolt formed at this end of the handle. The clamp jaws are opened and closed by rotating a nut located just below the lower jaw, also encircling the bolt. In this way the floss bundle can be removed and replaced between uses. The other end of the handle is also formed into a threaded bolt, having a hole diametrically bored through it, into which the wide end of a half toothpick is removably fitted.

Once removed, the insert may be replaced or readied for reverse installation on the handle, particularly where the portion of the handle containing the aperture is angled.

  • Patent number: 5038805
    Abstract: A device for cleaning teeth comprising a stiff plastic filament one section of which is curly in shape. This curly section has a longitudinal axis along which tensional forces lie when tensional forces are applied to stretch the device. This curly section also extends laterally to provide contact lines which are oriented at an angle with respect to the longitudinal axis to scrape away unwanted materials on the surface of the teeth when the curly section is pulled longitudinally through the interdental areas. The device can be fabricated by winding a filament around metal pin, heating the filament, and then cooling the filament to provide the curly shape.

  • Patent number: 5002077
    Abstract: The periodontal pocket cleaner is a device for cleaning the deeper recesses of a periodontal pocket by the removal of debris material. The device can also be employed for ascertaining and monitoring bleeding and suppuration within such pocket so as to detect the onset of an inflamation or other pathology and for delivering medication to such pockets as a complement for the treatment of infections or inflammation. The device has a wooden composition and an elongated narrow shape with the grain of the wood running parallel to the direction of elongation. The device includes a tapered end which narrows to a functional point to facilitate the insertion of the device into the deeper recesses of the periodontal pocket. This tapered end of the device also serves for scooping material from the pocket, for scraping plaque from the tooth surfaces adjacent to the pocket, and for absorbing blood and other suspended components from the pocket.
