  • Patent number: 10472485
    Abstract: The present invention relates to a composite powder of scoria powder and a porous polymer. More particularly, the present invention relates to a composite powder (scoria sphere) in which the surface and the inside of a porous polymer are uniformly impregnated with scoria powder particles prepared by spraying in one-step a dispersion in which scoria powder is dispersed in a solution in which a polymer is dissolved; a cosmetic composition containing the same; and a process for producing the same. When the scoria impregnated powder, of the present invention, in which the porous polymer is uniformly impregnated with the scoria powder particles, is formulated as a cosmetic composition, the porous polymer supplements the sebum absorption performance of the scoria miniaturized in a micro size, and thus the sebum absorption power is greatly improved.

  • Patent number: 10213281
    Abstract: A non-surgical treatment for receding gums utilizes the fact that tissue responds to continuous controlled mechanical forces with growth. The treatment system includes an impression of the upper and/or lower teeth, including the surrounding existing gums, so that a vacuum can be established within the impression around teeth and gums. Before use, selected portions of the impression are carved out a desired amount to create a location for the expansion and regrowth of the gums. Additionally, one or more channels may be included in the impression for delivery of the vacuum to all areas encompassed by the impression. The treatment system also includes a vacuum source operatively attached to the impression so as to be able to deliver a vacuum to the impression once the impression is place in the patient's mouth over the teeth and gums.

  • Patent number: 9801701
    Abstract: Digital design and/or fabrication of a dental prosthesis that includes a gingiva part having retention pockets and corresponding injection channels that extend from the retention pockets to an exterior of the gingiva part. The positioning of a matrix mated to a ball attachment of a dental implant is fixed in the retention pocket by injection of a curable adhesive through the injection channels and into the retention pockets. The location of the retention pockets and the injection channels may be automatically generated by a computer-aided design/computer-assisted manufacturing (CAD/CAM) system. The gingiva part including the retention pockets and injection channels can further be designed and fabricated by the CAD/CAM system.

  • Patent number: 9801700
    Abstract: A dental prosthesis has a gum sealing rim that snugly contacts the patient's gum. The cavity formed within the gum sealing rim is accessed by through holes via which a pressurized cleaning fluid may be injected into the cavity. The cleaning fluid swirls around and washes of bacteria and deposits. Through a number of cleaning fluid drains, the cleaning fluid exits again the cavity. An additional drain blocker may be configured such that it blocks the cleaning fluid drains while it is clamped by the patient between the teeth. The resulting pressure build up in the cavity causes the cleaning fluid to squeeze out and clean the sealing interface between the gum sealing rim and the patient's gum.

  • Publication number: 20080299517
    Abstract: The denture with suction attachment is an upper or lower denture plate having a floor with at least one suction cavity formed therein, at least one check valve for sealing the chamber formed by the suction cavity and the user's mouth when the denture is installed therein, and at least one suction passage extending between the valve and one suction cavity. The suction cavity may have one or more cavities extending generally across the span of an upper plate, or along the gum line of a lower plate. The suction cavity or cavities are preferably provided with a peripheral seal of a soft, resilient silicone material, or other suitable seal. A suction pump is also provided for removable attachment to the check valve. A magnetic attachment is preferably provided for securing the end of the interconnecting suction pump line to the check valve of the denture.

  • Patent number: 7338285
    Abstract: A dental cleaning attachment for a dental handpiece which comprises a disposable prophy angle having a neck and a right angle head, wherein the neck is removably attached to the dental handpiece. A polishing cup is rotatably connected to the head of the prophy angle. An encompassing toroidal pouch has a tube fluidly formed to and extending from the toroidal pouch. The tube runs externally along a top surface of the neck, is bent at a right angle, goes through a rear aperture in the head of the prophy angle and into a top aperture in the polishing cup. A paste material is carried within the toroidal pouch, the tube and the polishing cup. When the dental handpiece is gripped by a hand of a dental hygienist and the polishing cup is applied to a tooth, any finger of the hand of the dental hygienist can squeeze the toroidal pouch to force some of the paste material through the tube and out of the polishing cup, so that the paste material can be applied onto the tooth for cleaning.

  • Patent number: 7040895
    Abstract: A skin contacting plate is formed in the shape of the gums to which the plate is secured by a skin adhering compound on a perforated layer. A protruding ridge along the teeth line has an internal reservoir to receive a skin adhering compound solvent from a syringe-type liquid pump to dissolve the compound to remove the skin contacting plate when desired. A denture plate conforms to the shape of the skin contacting plate and the protruding ridge. A syringe-type vacuum air pump draws the air from between an internal passageway between the plates through a valve in the denture plate to form a vacuum to maintain the plates together. Pumping air into the internal passageway immediately releases the plates.

  • Patent number: 4583949
    Abstract: A dental prosthesis of the type secured to the alveolar ridge within the mouth of the user through the application of a partial vacuum which serves to stabilize and maintain a dental plate in secure operative position. A full or partial dental plate incorporates false teeth at least some of which have a hollow interior portion in which valve means are mounted in fluid communication with a pressure differential channel itself extending along and being disposed in fluid communication with exposed surface portions of the alveolar ridge. Application of negative pressure to the interior of the mouth serves to direct fluid flow from the differential pressure channel through the valving structure within the hollow interior portion wherein such valving structure prohibits reverse flow therethrough. A partial vacuum is thereby created and maintained between the undersurface of the dental plate, in the area of the differential pressure channel, and the exposed surface of the alveolar ridge.

  • Patent number: 4204322
    Abstract: Apparatus for securing a denture plate in position is disclosed. The illustrated and preferred embodiment incorporates a vacuum pump which has the exterior form and shape of a tooth embedded in a denture plate. The tooth incorporates a reciprocally operated pump. The pump pulls air from an exposed, lower indention or chamber. This chamber is connected via multiple passages to similar chambers around the denture, all of the chambers collectively open to the gum of the wearer. As air is evacuated from the chambers, a vacuum is formed. The vacuum increases holding power of the denture against the gum.
