摘要： In a method of coloring a ceramic material, a coloring solution consisting of metallic salts is introduced to a ceramic slurry. In a slip casting process, a coloring solution consisting of metallic salts is introduced to a ceramic slurry which is cast into green state bodies. A coloring solution that may comprise for example a metallic salt, a solvent, an organic solvent such as derivatives of propylene oxides, and an acid can be introduced to the slip casting process. Such a coloring solution can be added to the slip casting process. In a method, the coloring solution is thoroughly mixed with the ceramic slurry, after which a ceramic body is cast, dried and finally subjected to a sintering process. After final sinter, the resulting ceramic body possesses an innate color that is homogenous throughout its composition. The method is especially useful for coloring zirconia ceramic material used for making dental restorations.

摘要： A colored ceramic powder is produced from a mixture of coloring solutions consisting of metallic salts that are introduced to a ceramic slurry and subsequently dried. The coloring solution may comprise for example of chosen metallic salts, a solvent, an organic solvent such as derivatives of propylene oxides, an acid and a possible binder. Once all the constituents are thoroughly mixed to a homogeneous state, the slip is dried to a powder form, which spray drying equipment can be used. The dried powder can then be subjected to an isostatic or biaxial press manufacturing process to create a green state ceramic body. Once pressed, the ceramic body can be subjected to a sintering process. After final sinter, the resulting ceramic body possesses an innate color that is homogenous throughout its composition. The method is especially useful for coloring zirconia dental restorations.

摘要： A process for fabricating pre-sintered zirconia blanks that are then computer machined and sintered to form dental appliances having highly advantageous features. The principal steps of a preferred embodiment of that process comprise; a) preparing a ceramic slurry of zirconia powder; b) subjecting the slurry to attrition milling down to about a 5-29 nm crystallite size; c) preparing a vacuum assisted and pressure assisted slip casting mold and pouring the milled slurry into the slip-casting mold; d) after casting, excess slurry is poured from the mold and a consolidated zirconia blank is removed; e) drying the blank and pre-sintering it to form solid blanks ready for CAD/CAM machining and sintering to net shape. The attrition is run with ball bearings that are of the sample material to prevent contamination. It also is run, up to 24 hours, to break down the crystallites to overcome the high density of zirconia.

摘要： Dental restorations such as crowns, are made from lithium silicate glass ceramic that is heated and pressed onto a metal substrate, the latter being shaped to an impression or scan of the area of the mouth to receive the restoration. The metal substrate is made from an alloy selected to exhibit a coefficient of thermal expansion which is slightly greater than the CTE of the lithium silicate. In a preferred embodiment, the CTE of the lithium silicate glass ceramic is in the range of 11.5 to 12.5 and the alloy is selected to have a CTE of 12 to 13.5. A palladium tin alloy provides that CTE in the preferred embodiment.

摘要： Methods and apparatus that permit a dentist to provide a patient with a monolithic ceramic dental restoration (e.g., crown, bridge, or the like) in one office visit. In some embodiments, a dentist is provided with a kit containing one or more near net shape (NNS) millable blanks of various shapes and shades, chair-side software, and a chair-side milling machine to convert a selected millable blank into a finished, fully contoured restoration in about one hour or less. Each such millable blank may be, for example, a dental ceramic (e.g., fully sintered zirconia, fully crystallized lithium silicate, fully crystallized lithium disilicate, or the like) NNS component. In some embodiments, the NNS component includes an integral mandrel at a precise location and orientation to minimize the amount of milling time.
