  • Patent number: 6202897
    Abstract: An nozzle for storage and application of liquid dental material, such as primer or adhesive, to a preparation site at a patient's teeth, gums or mouth. The nozzle includes a hollow nozzle for containing the liquid dental material. The hollow nozzle can include a flocked, open tip through which the liquid dental material is dispensed. The nozzle also includes a storage block having a plurality of cavities formed therein. A plurality of hollow nozzles can be inserted into the cavities to form substantially air-tight seals between the open tips of the hollow nozzles and the exterior of the cavities. An end of the hollow nozzles opposite from the open tip and exposed above the block includes a breakable seal. Accordingly, the hollow nozzles can be stored in the block for an extended period of time. To apply the liquid dental material to a preparation site, an applicator can be attached to the end of the hollow nozzle exposed above the block.

  • Patent number: 6187838
    Abstract: The use of polymerizable monomeric conditioning agents for treating the enamel and dentin of a tooth prior to application of a primer and subsequent application of a bonding resin, or a combination of a primer/bonding resin has been found to provide good shear bond strength on both moist and dry dentin. In addition, the contact angles provided by water on dentin conditioned with the polymerizable conditioners as compared to the non-polymerizable phosphoric acid are much lower, reflecting improved spreading over the surface of the tooth.

  • Patent number: 6182820
    Abstract: A holder for dental implants namely dental veneers. The holder has a bottom tray and a top cover both opaque. The top cover has a recessed portion that is designed to receive a foam sheet. The foam sheet is designed to cover the top cover so that it blocks light from entering the closed holder. The bottom tray has recessed wells that are designed to receive dental veneers. When the cover is closed over the tray, the light is blocked out so that light-sensitive resin placed upon the dental veneers does not harden before the dental veneers are placed upon the patient's teeth.
