摘要： A dental prosthesis is made by externally machining successive layers of wax, each of which is formed on a previous prosthesis layer and/or on a coping. Each wax layer is used to form a mold in situ over the previous prosthesis layer/coping, and the appropriate prosthesis material is cast or otherwise molded to conform to the wax layer by the mold.

摘要： A resin block that can be favorably used for obtaining dental prosthetics through the milling work, containing very little voids, having excellent property for being cut, exhibiting excellent appearance and mechanical strength, and without permitting the formation of defective products. The resin block contains a thermoplastic resin having a fluidizing temperature in a range of 310 to 500° C. and inorganic particles in an amount of 30 to 150 parts by mass per 100 parts by mass of said thermoplastic resin. The inorganic particles are at least one kind of inorganic oxide particles selected from the group consisting of silica particles, silica composite particles of silica and other metal oxides, titania particles, and titania composite particles of titania and other metal oxides. The resin block has a thick portion of a thickness of at least not less than 5 mm, and does not contain any void whose length is not less than 1.0 mm.

摘要： A dental restorative device is shown as comprising a first cured or hardened layer in the form of an occlusal surface of the tooth being restored and a second uncured dental composite layer joined to the first layer enabling a dental professional to perform direct dental restoration procedures with results replicating indirect direct dental restoration procedures. A system comprising the multi-layered dental restorative device and packaging provides for sufficient support and protection of the uncured second layer and facilitates positioning and finishing of the dental restorative device by cooling the uncured portions to a rigid state while in the packaging, positioning the dental restorative device, and modifying the second layer to fit, curing the second layer and permanently placing the fully cured and hardened dental crown on the tooth being restored.

摘要： Provided are dental articles, and methods of making articles, having an aesthetic inorganic coating based on zirconia at least partially stabilized with yttrium oxide, calcium oxide, cerium oxide, or magnesium oxide. Stabilized zirconia coatings were found to provide a smooth, low friction surface having high abrasion resistance. These coatings are particularly applicable to orthodontic appliances. While virgin stabilized zirconia coatings can often have an undesirable color cast, it was discovered that this color cast can be substantially eliminated by heat treating the coated appliance in an oxygenated environment. The combination of depositing a stabilized zirconia coating and subsequently heat treating to decolorize the coating provides a surprisingly robust, stable, low-friction coating that is also aesthetic.

摘要： The invention relates to a method for manufacturing a colored blank, which contains zirconium dioxide and is intended for the manufacture of a dental restoration, whereby raw materials in powder form, at least some of which contain one coloring substance each, are mixed with, zirconium dioxide as the main ingredient, the resulting mixture is pressed and subsequently subjected to at least one thermal treatment. To generate the desired fluorescence, it is intended that in the raw materials in powder form one uses as coloring substances at least terbium, erbium, cobalt, as well as one substance that generates a fluorescence effect in the dental restoration, however not iron, aside from naturally occurring impurities.

摘要： A dental prosthesis is disclosed includes a prosthetic tooth element comprising ceramic and a veneer located on a surface of the prosthetic tooth element, the veneer comprising cured dental composite. The prosthetic tooth element can be fixed to a mount in a patient's mouth using the same dental composite used for the veneer. A method of forming a prosthetic tooth element is disclosed including filling a mould that is formed at least partially from flexible polymeric material with a dental mixture comprising ceramic, and applying pressure to the filled mould to form a prosthetic tooth element comprising ceramic with a roughened surface.

摘要： The invention relates to a method for the production of a dental restoration from a blank, which has regions or layers of ceramic materials with differing compositions, under use of the method steps, filling of the ceramic materials into a mold, pressing of the ceramic materials to form a blank, removal of the blank from the mold, temperature treatment of the blank, wherein the ceramic materials are filling into the mold in such a way that layers and/or regions after temperature treatment have a profile that is available as a digital set. There is then a virtual contouring of the dental restoration taking shrinkage into account, a virtual representation of the blank, positioning of the virtually represented dental restoration in the virtually represented blank taking into account the material characteristics of the layers and/or regions, determination of the data for the blank which correspond to the position of the virtually arranged dental restoration or the mold in the blank, as well as transfer of the data to a machine to produce the dental restoration from the blank.

摘要： A process for making a dental restoration includes forming a dental restoration base, selecting a decal representing a natural oral cavity characteristic, and attaching the selected decal to the base. Thereafter, the decal and the dental restoration base are conditioned to create a finished dental restoration having desired oral cavity color and characteristics such as teeth, enamel, dentin, crazing lines, stains, veins, blood vessels, bony coloration, hyper-calcification, mucosal tissue or gum tissue. In an alternative embodiment, the process may include placing a sealant over the decal and at least a portion of the dental restoration base. Additionally, a secondary decal may be attached over the sealant, followed by glazing the secondary decal.

摘要： The invention relates to a method for producing a dental restoration part, in which method, geometrical data, in particular data with respect to spatial dimensions, position and/or volume of the restoration part, are determined and stored in order to form a virtual restoration part. In a further process step, the virtual restoration part is provided for the tooth (10) to be replaced by using data of the tooth (10) to be replaced, a neighboring tooth (60) and/or a tooth stump, and said data is stored as color data and is used for the computer-assisted production of the virtual restoration part.
