Abstract: A dental prosthetic positioning assembly comprises an occlusal assembly and a maxillary arch subassembly. The occlusal assembly includes a maxillary tray configured to be formed in a patient's maxillary alveolar ridge, wherein the maxillary tray comprises a occlusal rim component. The occlusal assembly further includes a carriage frame component composed of biocompatible magnetic metal material anchored to the maxillary tray. The maxillary arch subassembly comprises a plurality of prosthetic maxillary teeth components magnetically anchored to the occlusal rim component. The carriage frame component is moveable with respect to the maxillary tray. The prosthetic maxillary teeth components are individually moveable with respect to each other to achieve a desired dental positioning.

Abstract: Disclosed are compositions and methods for bleaching and optionally coloring a shaded zirconia, particularly mono-chromatic pre-shaded dental zirconia. The compositions and methods are useful in generating a shade gradient in milled dental restorations. The compositions comprise metal salts or complex dissolved in a solvent.

Abstract: Disclosed herein are methods for creating opalescence in dental materials and restorations, compositions used in such methods, and the resultant dental materials and restorations. More particularly, the opalescence may be created by directly embedding opalescent particles into a matrix material. In some embodiments, photonic crystals are embedded in the dental material to achieve the opalescent effect. Photonic crystal particles may be embedded in dental materials matrices such as ceramics, composites, and polymers, and can generate opalescence in the materials. Some embodiments disclose compositions for applying the opalescence to a dental restoration.

Abstract: Adapters and dental mill blanks are provided which permit use of dental mill blanks of various shapes in dental mills designed for use with only a single shape. In particular, a mill blank assembly may include an adapter which allows for the use of rectangular, framed dental blanks in milling machines designed for use with puck-like milling blanks.

Abstract: A collaborative approach, incorporating a server for data transmission, security verification, and authentication verification, is implemented between a dental office and a dental laboratory to fabricate a designed dental restoration. A scanner is used in a dental office to take a scan of a patient's mouth. The dental laboratory designs the dental restoration with specialized design software taking into account the scan of the mouth as well as a prescription from the dental office. The parameters defining the designed dental restoration are contained in a design file. The design file is used to create milling specifications defining instructions for milling the designed dental restoration. The materials for the dental restoration are loaded into a mill, where the dental restoration is fabricated in accordance with the milling specifications. Security verification ensures authorized materials are used, and authentication verification ensures authorized materials and processes are used.

Abstract: An adjustable shelf personal care cabinet that employs a plurality of snap-in support rods that are removably mounted in the rear wall of the cabinet wherein the rods are structured to receive the edge of a shelf with the opposite edge received in a side wall of the cabinet or another support rod. The support rods are bifurcated at one end for contaction and entry into the rear wall to snap-in and remain until removed.

Abstract: An ozone generator utilizes one or more cylindrical anodes having disposed centrally therein an elongated cylindrical dielectric tube. The dielectric tube is filled with an inert gas at low pressure and contains at a first end thereof beyond the encirclement of the anode a relatively short electrode. In a preferred embodiment, the electrode takes the shape of a cone having the small end thereof coupled through the first end of the dielectric envelope to a source of high energy alternating electric power. The large end of the cone is open and directed toward the far end of the dielectric envelope. Electrons are emitted from the electrode and focused down the length of the dielectric envelope, creating an electron haze which induces a variety of electron focusing phenomena in an annular reaction space between the dielectric envelope and the encircling anode.
