Abstract: Disclosed is an information display system capable of efficiently browsing items of information related by links. When displaying the information obtained by accessing a network, a plurality of display areas are formed, and plural items of information are displayed in these display areas. In this case, a display history of the information displayed may be stored, and the items of information displayed at the present or in the past may be displayed in a predetermined order in the respective display areas. When a first item of information displayed in a first display area is related to a second item of information, and when given an indication of displaying a second item of information, the second item of information may be displayed in a second display area while keeping the display of the first item of information in the first display area.

Abstract: A process for making a ceramic inlay for filling a cavity in a tooth. A piece of metal foil is pressed into a depression in a jig, where the depression approximates the shape of the cavity; the pressed metal foil is annealed and the pressing and annealing steps are repeated until the foil has a concave depression roughly the same size and shape as the cavity. A ceramic layer is built up on the concave foil to form a ceramic inlay substantially reconstructing the tooth.

Abstract: A dental prosthetic device is provided comprising a coping adapted to be placed on at least one abutment tooth to an edentulous region. A pontic metal substructure adapted to be joined to the coping and a ceramic buildup to fill the edentulous region are also provided. Also provided are metal-porcelain dental restorations which can be made in a two-layer or three-layer structure. The first layer closely fits the contours of the abutment teeth and ceramic and the additional layer complete the restoration. One or both of the other layers may be stainless steel mesh.

Abstract: A metal porcelain dental restoration for filling an edentulous region is provided. The dental restoration comprises a first layer of a thin metal foil which closely fits the contours of the two abutment teeth on either side of the edentulous region, a layer of ceramic on the first metal foil layer, a second layer of thin metal foil connected to the ceramic layer and extending at least across the joint from the abutment teeth to the edentulous region and a ceramic build-up to fill the edentulous region.

Abstract: A metal foil is provided for use in a metal-porcelain dental restoration, which metal foil provides improved color qualities to the finished restoration and improved bonding of the metal to the porcelain. The metal foil is made of an alloy comprising a major amount of gold, an amount of platinum or palladium, and an amount of a non-precious metal. An improved dental veneer and dental bridge can also be made using the metal foil of the invention.

Abstract: A method is provided for uniformly fitting a foil to a die in the manufacture of a porcelain-metal dental restoration, the method including the application isostatic pressure to a foil covered die. The inventive method is more economical and not as laborious as prior art methods, and provides a superior fit of the foil to the die, resulting in a better quality restoration.

Abstract: A method is provided of coloring bakeable porcelain dental restorations. A plurality of pigmented coloring solutions is provided for application to a porcelain restoration. Each coloring solution comprises a pigment of low temperature porcelain-fusable powder and a substantially clear carrier liquid that supports a dispersion of said pigment and vaporizes when the restoration is baked. A film of the coloring solution is coated onto said restoration and then cured. The steps of coating the restoration and curing the film are repeated as necessary to match the color of the restoration to the color of a patient's teeth. The coated restoration is then baked to fuse the pigment to the porcelain and vaporize the cured carrier liquid.

Abstract: A baked metal-porcelain dental restoration is provided, including a method of making same. The restoration includes a substrate formed from a non-cast thin metal foil having a textured exterior surface onto which a dental porcelain jacket is directly bonded without any intermediate interface compositions. The exterior of the porcelain jacket may be configured as necessary to provide a desired occlusal surface.The dental restoration is made by providing a support post with a configuration that corresponds to the shape of a tooth base in a patient's mouth. The support post is coated with a thin spacing layer. A thin metal foil is swaged around the coated support post to substantially conform to the shape of the post. The exterior of the foil substrate is textured and porcelain powder is applied thereto without the use of any intermediate interface composition between the foil and powder. The metal substrate and applied powder are baked to bond the porcelain directly to the metal foil.

Abstract: An improved kiln or oven useable support structure is provided which includes a base having a surface with a plurality of vertically oriented support bores disposed thereacross. A plurality of straight and crank shaped support pins having predetermined cross-sections are removably insertable into the bores of said base. A curved support member has in one end an aperture having a configuration minimally larger than the cross-section of said support pins. When said aperture encircles a support pin and the axis of said aperture is substantially parallel with said pin the two move freely with respect to one another, but when the axis of said aperture is not substantially parallel with said pin, the two pinch-lock or bind to maintain their relative positions.

Abstract: This invention relates generally to a method and instrument for fabricating a first dental restorative having a predetermined standard occlusal contact relationship with an opposing second dental restorative and for fabricating a pattern for such first restorative.

Abstract: This invention relates generally to an instrument used in making dental restoratives and more particularly concerns a unitary instrument used to perform the functions of mixing and applying porcelain paste to a metal understructure utilized in the dental restorative and for condensing the porcelain paste subsequent to being applied to the understructure.

Abstract: A composition for marking the contact points on the occlusal surface of a dental restorative or a natural tooth and for use in evaluating the mode of contact between occluding teeth.
