摘要： Oral treatment devices formed from wax-based compositions that are thermally stable when formed into a three-dimensional shape to a temperature of at least 45° C. and plastically deformable at room temperature (25° C.). The wax-based compositions include a wax fraction homogeneously blended with a polymer fraction. The wax fraction includes at least one wax. The polymer fraction includes at least one polymer selected such that, when the wax and polymer are homogeneously blended together, they yield a wax-based composition having the desired properties of thermal stability and plastic deformability. Oral treatment devices are dimensionally stable to a temperature of at least 40° C. without external support and can be plastically deformed in a user's mouth to become at least partially customized to the size and shape of user's unique dentition and/or an appliance in a user's mouth.

摘要： A dental curing light includes a thermally conductive device body that efficiently conducts heat away from a light emitting diode (LED) assembly. The thermally conductive device body extends between a proximal end and a light emitting distal end to which the LED assembly is thermally coupled. The thermally conductive device body includes a handle portion extending to the proximal end and that is sized and configured for a dental practitioner to hold and manipulate with the hand. The thermally conductive device body acts as a heat sink to efficiently conduct heat away from the LED assembly during use. An electronics assembly and a rechargeable battery are disposed within a cavity of the thermally conductive device body. A sleeve or collar can be attached to the proximal end of the thermally conductive device body.

摘要： 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.

摘要： Wax-based compositions for making barrier layers used in oral treatment devices are thermally stable when formed into a flat sheet or three-dimensional article to a temperature of at least 45° C. and are plastically deformable at room temperature (25° C.). The wax-based compositions include a wax fraction homogeneously blended with a polymer fraction. The wax fraction includes at least one wax and the polymer fraction includes at least one polymer selected such that, when the at least one wax and at least one polymer are homogeneously blended together, they yield a wax-based composition having the desired properties of thermal stability and plastic deformability. Barrier layers in oral treatment devices made from such wax-based compositions are dimensionally stable to a temperature of at least 40° C. without external support and can be plastically deformed in a user's mouth to become at least partially customized to the size and shape of user's unique dentition.

摘要： 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).
