  • Patent number: 10368814
    Abstract: A method for 3-D cephalometric analysis of a patient, executed at least in part on a computer processor, displays reconstructed volume image data from a computed tomographic scan of a patient's head from at least a first 2-D view and accepts an operator instruction that positions and displays at least one reference mark on the at least the first displayed 2-D view. One or more dentition elements within the mouth of the patient are segmented and cephalometric parameters for the patient computed and displayed according to data from the at least one reference mark and the one or more segmented dentition elements. Using the computed cephalometric parameters, one or more results indicative of maxillofacial asymmetry are computed and a graphical or text display energized to show the computed results indicative of asymmetry.

    Abstract: Composition and methods include a dental bleaching agent, potassium nitrate a fluoride salt for enhanced whitening and reduced tooth sensitivity. The potassium nitrate and fluoride salt both reduce or eliminate tooth sensitivity that may otherwise be caused by the bleaching agent. For prolonged treatment of teeth, lower quantities of potassium nitrate (e.g., 0.5%) have actually been found to work better than larger quantities (e.g., 3%). The dental compositions may be applied directly to the person's teeth, or they may be loaded into a comfortable fitting, flexible, thin-walled dental tray and placed over the person's teeth. In that case, the dental compositions will include a tackifying agent, such as carboxypolymethylene, which assists the composition in retaining the dental tray over the person's teeth as a result of the adhesive properties of the dental composition rather than due to mechanical interlocking of the tray over the person's teeth.

    Abstract: A hand-held, ergonomic instrument with an LED that emits actinic light in visible wavelengths mounts a replaceable applicator cup with a reservoir for a tooth whitening composition held in place against a user's tooth during a whitening procedure. Actinic light is directed onto the tooth surface through a window in the cup and the tooth whitening composition substantially without attenuation, delivering at least about 100 milliwatts per square centimeter of light energy to the tooth surface. The cup includes a rigid body for mounting the cup to the instrument and an opaque flexible sleeve molded in place over the outside of the body to form a seal with the tooth surface and prevent exposure of soft mouth surfaces to the actinic radiation during a whitening procedure. A safety switch disables the LED when the applicator cup is not in contact with a tooth surface.

  • Patent number: 8852561
    Abstract: Fluoride varnish compositions for temporary application and adhesion to a person's teeth. The composition includes a carrier comprising a resin and an adhesion promoting agent comprising an alkyl phosphoric acid. A fluoride ion source (e.g., a fluoride salt such as sodium fluoride) is dispersed within the carrier so as to provide biologically available fluoride ions to the tooth tissue being treated. The composition adheres only temporarily to tooth tissue (e.g., for a period of at least about 4 minutes, but not more than about 1 year), after which the composition spontaneously wears away as a natural result of the action of the tongue, saliva and/or other factors.

  • Patent number: 8852560
    Abstract: A dental bleaching composition comprises a dental bleaching agent and a polyvinylpyrrolidone thickening agent. The bleaching composition may include water, flavoring agents, a basic substance and desensitizing agents, as desired. Polyvinylpyrrolidone avoids acid etching and chelation of teeth that were problematic in bleaches using carbomer as a thickener. A delivery system for delivering the bleaching composition comprises the aforementioned dental bleaching composition in combination with a moisture-resistant barrier layer such as a dental tray or a flexible strip of material.

  • Publication number: 20140271781
    Abstract: A composition is provided, wherein the composition comprises a water-swellable, water-insoluble polymer, a blend of a hydrophilic polymer with a complementary oligomer capable of hydrogen or electrostatic bonding to the hydrophilic polymer. The composition also includes a backing member. Active ingredients, such as a whitening agent, may be included. The composition finds utility as an oral dressing, for example, a tooth whitening composition that is applied to the teeth in need of whitening. The composition can be designed to be removed when the degree of whitening has been achieved or left in place and allowed to erode entirely. In certain embodiments, the composition is translucent. Methods for preparing and using the compositions are also disclosed.

  • Patent number: 8813364
    Abstract: Methods for making a layered dental appliance. Some methods can include providing a solid structure (e.g., a die or a dental core, such as a fully sintered ceramic dental core) having a desired outer shape, and applying a first slurry to the solid structure to form a first free form layer on the solid structure. The method can further include solidifying the first free form layer on the solid structure, and machining the solidified first free form layer to a desired shape to form a first article comprising the solid structure and a first shaped layer. The method can further include applying, solidifying, and machining a second layer in a similar way to form a second article comprising the solid structure, the first shaped layer, and a second shaped layer. In some methods, the free form layers are not exposed to a high temperature prior to being machined.

  • Patent number: 8795638
    Abstract: This invention pertains to dental care compositions with antimicrobial benefits. In particular, the invention provides for compositions of oral tissue-adherent salts that release biocidal ions on a controlled release basis and thereby provide and maintain an essentially uniform concentration of biocidal ions above the MBC or MIC of the target bacteria at the site of application in the mouth for an extended period of time. The compositions are useful for treating or preventing oral diseases resulting from bacteria, fungal or yeast infections, such as caries, gingivitis, periodontal disease and candidiasis.

  • Publication number: 20140170593
    Abstract: Adhesive patches for non-invasive pain relief comprising a molded backing layer including first and second well portions. An adhesive composition (e.g., chitosan derived) is disposed within the first well composition, and a skin penetrating anesthetic composition is disposed within the second well portion. The first well portion surrounds the perimeter of the second well portion, creating a barrier to prevent or minimize migration of the anesthetic composition outside the perimeter of the second well portion, targeting delivery to the desired site. The skin penetrating anesthetic composition includes a skin penetrating carrier (e.g., DMSO with small fractions of water and ethanol), a primary adhesive component (e.g., hydroxypropyl cellulose) to render the anesthetic composition sticky to the person's tissue, and at least one anesthetic component (e.g., -caine based components). Where two anesthetic components are included, one may act more rapidly to anesthetize pain than the first anesthetic component.
