  • Patent number: 6309222
    Abstract: A portable dental containment device for use in manipulating dental fixtures, including veneers, in-lays, partials, dentures and other prosthodontics, the device including a transparent enclosure with hand-holes. The dental containment device provides a protected work space in which a dentist, dental assistant, technician, or the like, can manually adjust small fixtures using various hand tools without the risk of ejecting the fixtures, or parts thereof, onto the floor and other unsterile surfaces. The containment device may include autoclavable materials, attachment mechanisms for attaching the shield to a tray, counter top, or other surface, and a magnified viewing area.

  • Patent number: 6206698
    Abstract: A hand-held dental instrument for use in condensing and packing soft, composite filling material. The condenser includes resiliently pliable, bulbous tips of various diameters, having a pliable surface such as rubber or soft plastic that deforms under hand pressure and returns to its original shape upon removal of said pressure. The condenser enables a dentist, dental assistant or technician to condense efficiently and uniformly composite filling material into a prepared tooth cavity. The condenser is an improvement over the typical existing art, which comprises rigid metal, plastic or ceramic tips of relatively small diameter, designed for condensing silver amalgam filling material. The condensing instrument provides a solution to the problem of rigid tipped condensing instruments applying uneven pressure into the soft composite, pushing holes or air pockets into the material rather than condensing it.
