  • Publication number: 20150062957
    Abstract: Disclosed herein is an improved dental operatory lamp having an LED light source that directs light to a reflector that in turn reflects the light to illuminate a treatment area. In one embodiment, the lamp is adapted for efficient transfer of heat from the light source and into the environment. In another embodiment, the lamp is adapted to generate a predetermined pattern of light optimal for the treatment area. In other embodiments, the lamp includes structural features that enable the lamp to maintain optimum light intensity and/or temperature. Also, disclosed herein are unique reflector embodiments that intentionally provide a generally smooth surface, without facets, that reflect light at all visible and infrared wavelengths.

  • Patent number: 8096807
    Abstract: An instrumentation delivery unit which supports hand-held dental instruments. In one example first and second housing members form a sealed chamber. When the members are separated, access is permitted to the interior of the chamber, e.g., for maintenance purposes. A first portal suitable for connection to a vacuum line provides a partial vacuum in the chamber, and second portals provide connection via second vacuum lines between the chamber and dental devices to operate the devices. The housing includes hand piece holders each of an initial diametric size for receiving hand pieces up to a maximum diametric dimension, with one of the hand piece holders formed along two adjoining ones of the housing members. The adjoining housing members secure inserts between one another to provide a second diametric size smaller than the initial diametric size to thereby selectably accommodate hand pieces having a smaller diametric dimensions.

  • Patent number: 7922138
    Abstract: Disclosed herein is a dental apparatus having a flexible arm for a dental apparatus. A benefit of the inventive flexible arm is the ability to make fine adjustments in orientation of one end of the arm relative to the other. More specifically, the ability to adjust or optimize the horizontal attitude of a movable end of the arm quickly and easily without resorting to expensive and time consuming remanufacture of the arm components. Adjustment of the end of the arm is accomplished via an adjusting mechanism with a rotatable shaft having an offset pin, where rotation of the shaft caused the pin to translate as defined by the offset of the pin center relative to the shaft center.

  • Publication number: 20100190131
    Abstract: Disclosed is a dental utility system for managing dental utilities, including a dental utility housing, a dental delivery assembly base fixed to the front side of the dental utility housing, and a dental delivery assembly main arm horizontally pivotably connected to the dental delivery assembly base and which permits vertical movement of a dental delivery assembly main arm distal end. The dental delivery assembly base and a dental delivery assembly base cover define a dental utility housing utility pathway that directs dental utilities from the dental utility platform to the dental delivery assembly main arm. Also included are a dental utility platform, and a dental utility platform extendable mount. The dental utility platform extendable mount permits the dental utility platform to be positioned anywhere along a continuous range of positions.

  • Publication number: 20100061798
    Abstract: Disclosed herein is an articulated arm (60) of a dental examination light having a pivot bearing (20) with an adjustable resistance feature. The pivot bearing (20) includes a split bushing (40) with first and second edges (42, 48) is mounted in a channel (28) in an interior diameter (23) of a housing (22). A ramp (30) forms an end of the channel. An axle (24) is rotatably mounted in the bushing. A setscrew (36) is mounted in the housing tangentially to the bushing. A cutout (46) in the bushing receives a portion of the setscrew. Turning the setscrew pushes a front end of the setscrew against an abutment (47) of the bushing, pushing the first edge of the bushing into the ramp, which redirects the first end of the bushing radially inward against the axle when the setscrew is tightened, thus providing bearing resistance adjustment. The tangential orientation of the setscrew minimizes housing thickness required for the setscrew.
