  • Patent number: 10517813
    Abstract: Methods for use in selectively conditioning and remineralizing teeth. An exemplary method comprises the steps of applying a conditioning composition to one or more of a person's teeth, and separately applying a remineralizing composition to the person's teeth. The conditioning composition includes a conditioning agent, and the remineralizing composition includes a remineralizing agent comprising calcium ions and/or fluoride ions. The conditioning composition may be applied prior to or after application of the remineralizing composition. In one embodiment, both the conditioning composition and the remineralizing composition include different remineralizing ions (e.g., one including calcium, one including fluoride).

  • Patent number: 10449123
    Abstract: Fluoride varnish compositions for temporary application and adhesion to a person's teeth include a carrier that remains stable and translucent during storage. The compositions include a carrier comprising a stable and translucent resin and a fluoride ion source (e.g., a fluoride salt such as sodium fluoride) dispersed within the carrier so as to provide biologically available fluoride ions to teeth being treated. The carrier resists formation of solids that can plug a 25 gauge (or 10 gauge) syringe brush applicator tip. The compositions may also include an adhesion promoting agent comprising an alkyl phosphoric acid. 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: 10369085
    Abstract: Dental cement compositions (including two-part compositions), kits, and related methods are used for bonding a dental prosthetic appliance to a tooth. A first part includes an amine activator component and a zinc oxide reactive filler, while a second part includes a polymerization initiator (e.g., benzoyl peroxide) and a polymerizable component having a structure including at least one acrylate or methacrylate group at one end and a carboxylic acid group at another end. A temporary cement composition advantageously exhibits reduced compressive and/or bonding strength relative to permanent cement compositions, which provides sufficient strength to facilitate normal use of the teeth while the provisional appliance is in use, while also facilitating easy removal of the provisional appliance for replacement with a permanent appliance at a later time.

  • Patent number: 10307049
    Abstract: Provided herein is a retraction device for retracting soft tissue from the dental surfaces in the oral cavity of a patient. The retraction device is comprised of a topology conformable structure, where the topology conformable structure is adaptable to be delivered to the oral cavity in a constrained shape. The device can then undergo a conformation change in the oral cavity, where the device transforms into its unconstrained shape. The unconstrained shape of the device creates a useable working field in the oral cavity. The useable working field can provide increased accessibility to and/or visibility within the oral cavity. Also provided herein are methods for using the device and kits.

  • Publication number: 20190099068
    Abstract: Systems and methods for viewing stereoscopic video images are disclosed. In one example, a stereoscopic video imaging and tracking system can include a first video camera to generate a first video feed of a subject; and a second video camera spaced a distance from the first video camera to generate a second video feed of the subject, wherein the first video camera and the second video camera are directed toward a convergent point to provide a stereoscopic image of the subject. The system can also include a tracking system to cause the first video camera and the second video camera to follow a tracking point to maintain stereopsis of the subject. A head mountable video display can be present to display the stereoscopic image.

  • Publication number: 20180332255
    Abstract: Systems and methods for viewing stereoscopic video images are disclosed. The systems can include a first video camera configured to generate a first video feed of a subject, and a second video camera configured to generate a second video feed of the subject. The first video feed and the second video feed combined generate a near real-time stereoscopic video image. A tracking module can be associated with the first video camera and the second video camera, and can be configured to cause the first video camera and the second video camera to be directed to a desired convergent point relative to a selected tracking point to maintain stereopsis. The system may further include an array of video cameras, a gesture control module, an image adjustment module, a calibration module, or a 3-D modeling module, for example.

  • Patent number: 10016258
    Abstract: Cheek and lip expansion devices including an upper frame portion configured to extend about an upper dental arch, and a lower frame portion configured to extend about a lower dental arch. The upper and lower frame portions may each include first and second side members, each with anterior and posterior regions. An upper connecting member may extend between the anterior regions of the upper side members. A lower connecting member may extend between the anterior regions of the lower side members. The posterior regions of the upper and lower side members on respective sides of the frame are joined to one another to form a bendable radius that resists bending at a distinct point. The bendable radius on opposed sides permits the frame to be collapsed top to bottom. The frame may be collapsible side-to-side. A posterior crossbar may be provided extending between the posterior regions of the side members.

  • Patent number: 9949809
    Abstract: Non-customized dental treatment trays used to provide a desired treatment are formed from elastomeric silicone or silicone-like material. They may be molded from a two-part liquid silicone composition or a silicone-like TPE material (e.g., preferably SEBS and/or VERSAFLEX™ thermoplastic elastomer). The dental treatment trays possess high adaptability, flexibility, softness, and elastic elongation while also exhibiting resiliency in order to readily conform to the ridges, depressions and contours of a person's teeth during use. The trays possess a greater ability to adhere to a person's teeth compared to non-elastomeric thermoplastic materials. Due to their high adaptability and conformability, the non-customized dental trays behave like a semi-custom dental tray when placed over conformed to a person's teeth, particularly when used in combination with a sticky, viscous treatment composition.

  • Patent number: 9901332
    Abstract: Cheek retraction devices including an upper frame element configured to bear against and retract soft oral tissue from one or more teeth of an upper dental arch, a lower frame element configured to bear against and retract soft oral tissue from one or more teeth of a lower dental arch. The upper and lower frame elements may each include left and right frame portions wherein the upper and lower left frame portions are joined to one another to form a v-shaped hinge on one side of the frame, while upper and lower right frame portions are joined to one another to form a v-shaped hinge on another side of the frame. The v-shaped hinges on opposed sides permit the upper and lower frame elements to be at least partially folded toward each other. A posterior frame element may be provided extending between the v-shaped hinges.
