  • Patent number: 10646315
    Abstract: 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.

  • Patent number: 8356412
    Abstract: This patent relates to a machine that automatically assembles, inspects, and packages disposable prophylaxis angles. The machine includes a movable table including a plurality of fixtures on which angle components are assembled and the assembled angles are inspected. The movable table is surrounded by a number of stations, each of which performs a different operation of the assembly and inspection procedure. Feeders automatically supply the angle components to their respective stations for assembly. Angles that are incorrectly assembled are automatically rejected. Properly assembled angles are automatically sealed in individual bags. Individually bagged angles are counted into batches by the machine and automatically sealed into cartons.

  • Patent number: 8261748
    Abstract: A device for treating sleep apnea, the device comprising a tongue attachment member and a maxilla attachment subassembly. The tongue attachment member is fabricated having a sheath interlock member extending upward from a dorsal side of a sheath. The sheath is shaped to conform to a surface of an individual's tongue. A tongue receiving cavity is formed within the sheath, the cavity comprising an opening provided at a proximal end for receiving the individual's tongue. The sheath is referenced having a dorsal side and a ventral side. A sheath interlock member extends outward from the dorsal side. The maxilla tray is shaped to conform to and removably engage with an individual's upper dental arch. A tray interlock member extends from an interlock side of the maxilla tray and is positioned to interlock with the sheath interlock member, whereby the system extends an individual's tongue forward to treat sleep apnea.

  • Patent number: 8210847
    Abstract: A sterile, substantially maintenance free disposable dental handpiece is constructed from two shells and a center core, the center core having a flow deflector on one end. The shells are joined around the core with mating protrusions and/or tapered walls to form the body and head of the handpiece. A base is integrally-formed with the center core. The base has conduits that allow entry of light and pressurized air and/or water into the body. The head at the opposite end of the body from the base rotatably mounts an impeller assembly having an impeller shaft. The impeller shaft includes blades driven by the pressurized air. The blades can have cavities to reduce weight.
