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.

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.

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 and 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.

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.

A dental curing light includes a device body that efficiently conducts heat away from the light emitting diode (LED) portion of the curing light. The device body is one-piece body formed from a continuous seamless piece of thermally conductive material extending between a proximal end and a distal end. The one-piece body includes a gripping handle portion extending to the proximal end and a light-emitting head portion extending to the distal end. The one-piece thermally conductive body acts as a heat sink to efficiently conduct heat away from the LED dies during use. The one-piece body eliminates problems of multi-segmented curing lights that include one or more joints between adjacent segments. Eliminating joints increases thermal conductivity of the body, eliminates crevices where microbes can grow, and eliminates the risk of accidental separation if the curing light is dropped.

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.

A dental curing light includes a device body that efficiently conducts heat away from the light emitting diode portion of the curing light. The device body includes a proximal gripping end and a distal head end. The device body is formed from a thermally conductive body material. Excellent heat conduction away from the LED dies is achieved using a thermally conductive layer disposed over the device body. The thermally conductive layer serves as a conduit to quickly conduct heat away from the LED dies for dissipation within the material of the device body. In this manner, the material of the device body serves as a highly efficient heat dissipater. The surface area coupling the thermally conductive layer to the device body is sufficiently large that a majority (e g, substantially all) of heat being conducted by the thermally conductive layer is transferred to the device body during operation of the device.
