  • Patent number: 10531934
    Abstract: A system and method for repositioning teeth in a patient jaw includes an attachment bonded to a tooth. The attachment has at least one force receiving component for receiving a force. A polymeric shell repositioning appliance is positioned over at least some of the teeth in the patient jaw. The polymeric shell has at least one force transmitting component for engaging the force receiving component to form a locus of engagement. The locus of engagement transmits the force and moves but is maintained as the tooth is repositioned. In specific embodiments the locus of engagement is maintained over a substantial range of motion. The force transmitted at the locus of engagement increases in response to the tooth lagging an intended position. A space between the positioned appliance and the tooth permits the tooth to move into an intended position.

    Abstract: A method for segmenting a feature of interest from a volume image acquires image data elements from the image of a subject. One or more boundary points along a boundary of the feature of interest are identified according to one or more geometric primitives with reference to the displayed view. A foreground seed curve is defined according to the one or more identified boundary points. A background field array that lies outside of, and is spaced from, the foreground seed curve by a predetermined distance, is defined. Segmentation is applied to the volume image according to foreground values obtained according to image data elements that are spatially bounded on or within the foreground seed curve and according to background field array values to create a segmented feature of interest.

  • Patent number: 8298329
    Abstract: Unlike conventional dental ceramic powder made by grinding, dental ceramic nanocrystals are formed by vaporization into individual particles. Tetragonal zirconia particles thus formed are not broken into pieces, and so do not transform to weaker monoclinic zirconia and weaker sintered products. The particles created by this approach can be much smaller, and dental prostheses sintered from this powder can be stronger and more realistic. For instance, the smaller size of sintered tetragonal zirconia crystals increases optical translucence by reducing scattering from birefringence, and the small average particle size and tight distribution of sizes and shapes can essentially eliminate pores in a sintered product. Cylindrical and spherical particles can be manufactured by this approach, whereas prior art dental ceramic particles were generally neither.

  • Publication number: 20080038696
    Abstract: To fabricate a new denture from an existing denture, the existing denture for a patient is sensed. The existing denture corresponds to one or more of a mandibular edentulous ridge, maxillary edentulous ridge, and palate of the patient. In addition, a model is generated of the one or more of the mandibular edentulous ridge, maxillary edentulous ridge, and palate and a wax arch of teeth is modulated in response to a sensed arch of the existing denture. Furthermore, a wax up is generated corresponding to the existing denture by filling a gap between the wax arch and the model and the new denture is fabricated corresponding to the existing denture by investment casting the wax up.

  • Patent number: 7322821
    Abstract: A positioning device for dental implant has a post and multiple guides. The post is cylindrical and has a diameter corresponding to a diameter of a hole in a dental model. The guides are mounted detachably on the post and are semi-tubular tabs and each has an inner concave, an inner diameter, and an outer diameter. The guides are mounted concentrically one another. A dentist can use the positioning device to precisely position a drill bit of a drilling device on an edentulous place of a patient's jaw bone and drills a bone cavity suitable for a dental implant. The drill bit can be easily inserted into the patient's mouth without opening excessively.

  • Patent number: 7252509
    Abstract: Templates are disclosed that permit an orthodontist to accurately place appliances such as bracket shims or brackets on a tooth or teeth at a desired position. The templates can be used for accurately locating the position of other dental or orthodontic procedures, such as varnishing, tooth etching and root canals. The templates are made from a flexible sheet of material adapted to be adhered directly to the surface of the tooth or teeth. The sheet of material is formed with the outline of the tooth or teeth or in the shape of the tooth to allow the template to be posited in a proper, reference position. The sheet of material is also formed with one or more marks indicating the location of the bracket on the tooth, for example one mark indicting the bracket base location and other marks indicating the orientation of the base and bracket slot.

  • Patent number: 7097449
    Abstract: The present invention is directed to a dental bracket and associated kit used to attach a medicament-releasing pellet on a tooth. The kit is designed to provide slow release of fluoride or other medicament over a desired period of time. The medicament release kit includes a medicament-releasing pellet and a dental bracket. The bracket comprises a base and a socket configured to receive and retain the pellet at least partially therein. The device may be installed by a dental practitioner and remain attached to a patient's tooth for a few months or up to 20 years. The medicament-releasing pellet, designed to slowly release small quantities of fluoride or another medicament, may be replaced, for example, every 6 months to 2 years. Replacement of the medicament-releasing pellet may be performed at home or at a dentist's office.

  • Patent number: RE44046
    Abstract: A light hardening device is provided for hardening a light hardenable mass applied for dental purposes that has a first light emitting diode for emitting light at a range of intensities corresponding to a set of wavelengths which at most only partially overlap a range of light sensitivities of a photo initiator comprised in the mass. The light hardening device also includes a second light emitting diode for emitting light at a range of intensities corresponding to a set of wavelengths which overlap the set of photo initiator light sensitivities to a relatively greater extent than the partial overlap of the range of first light emitting diode intensities with the range of photo initiator light sensitivities.
