Abstract: A process to make/seat a permanent crown in only one patient visit, without the need for a temporary crown, after a digital scan or other impression has been taken prior during a dental cleaning appointment or status check up. The dental information is filed and can be used whenever the patient needs a dental restoration to be made. The impression information will have previously been forwarded to a dental laboratory where a shell-crown can be made that is a perfect match to the outer contour of the existing tooth. Needed improvements/corrections can be made with the use of digital software. Also the margins can be determined and corrected, even in the inter-proximal spaces. Now the laboratory is able to manufacture and provide a finished shell-crown in time for the following doctor appointment of this patient.

Abstract: A colored ceramic powder is compacted into a green state body via isostatic or biaxial pressing. The colored ceramic powder is produced from a mixture of a coloring solution consisting of metallic salts that is introduced to a ceramic slurry and subsequently dried. A coloring solution may comprise for example a metallic salt, a solvent, an organic solvent such as derivatives of propylene oxides, and an acid. Such a coloring solution can be used as a coloring agent for a ceramic body. The solution is thoroughly mixed with the ceramic slurry. Following the addition of the coloring agent, a binder can be added to the color slip. The amount of binder added can be anywhere from 0.5% to 10% by weight. Such a binder can be organic based, alcohol based, or acrylic based. Once all the constituents are thoroughly mixed to a homogeneous state, the slip is dried. The drying process can range from a conventional means to a more sophisticated methods which use spray drying equipment.. The slip can be subjected to a heating process over a range of temperatures such that all residual moisture is removed, leaving only a dried press-able powder. 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.

Abstract: Coloring in a slip casting process by which a ceramic slurry is cast into green state bodies. It is during this slip casting that a coloring solution consisting of metallic salts is introduced to the slurry and subsequently slip-cast. A coloring solution 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. The solution is thoroughly mixed with the ceramic slurry, after which the 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 dental restorations.

Abstract: 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.

Abstract: Rapid sintering techniques for densifying zirconium dioxide based ceramic materials employing electromagnetic induction heating or inductive coupled plasma to obviate stress limitations of conventional resistive heating elements of prior art sintering ovens, reducing processing time from hours to minutes. In a first embodiment a water-cooled copper tube forms a coil which is connected to a radio frequency power supply. The coil surrounds a susceptor body which in turn surrounds the ceramic to be sintered. The susceptor heats up in response to the rotating magnetic field emanating from the coil as the coil receives electric power. The heat in turn is radiated from the susceptor and heats the ceramic. In a second embodiment, the coil is connected to a radio frequency power supply of sufficiently high frequency and power to establish a plasma in the gas which surrounds the ceramic. The plasma then heats the ceramic. The method is especially useful for sintering ceramic dental appliances, such as crowns and bridges, in minutes which can lead to in situ fabrication of such appliances while a dental patient waits in the dental office.
