Abstract:
A core for obturating a root canal includes a body that has a pre-formed contour that closely matches a contour of the root canal. When the core is inserted in the root canal with or without sealer, there are essentially no voids in the root canal. A method of making a customized root canal obturation core includes generating a three-dimensional image of a root canal. The method also includes manufacturing the customized root canal obturation core based on the three-dimensional image of the root canal. The customized root canal obturation core has a preformed contour that closely matches a contour of the root canal such that when the core is inserted in the root canal with or without sealer there are essentially no voids in the root canal.
Abstract:
A dental arch model and method for making the same is shown and described. The dental arch model includes a connector having opposite ends that connect to a respective one of the arch legs. The connector has a three-dimensional shape but does not include a surface that is both planar and parallel to the base of the arch connector along more than two thirds of the arch connector's length. In certain examples, the connector is in the shape of a prism or a trapezoid. In other examples, the connector has an upper surface that is sloped relative to the base of the arch connector. The arch connector may also include a plurality of fluid passageways for allowing fluid flow from an interior area between the inner walls of the arch connector to a location outside of the connector.
Abstract:
Custom dental prosthesis or implants each individually designed and manufactured to replace nonfunctional natural teeth positioned in a jawbone of a specific pre - identified patient are provided. An example dental prosthesis/implant includes a dental implant body having a prosthesis interface formed therein to receive an occlusally- facing dental prosthesis component. The prosthesis interface has a custom three-dimensional surface shape positioned and formed to create a form locking fit with respect to the occlusally- facing dental prosthesis component when positioned thereon. The outer edge of the prosthesis interface is asymmetrically arranged to follow the patient's gum line.
Abstract:
A system comprises a rapid prototyping device (100) and a material cartridge (10, 101 ). The rapid prototyping device (100) comprises a chamber (102, 103) for building up the object (30). The material cartridge (10, 10') comprises a body (11) into which a channel (13) extends. A support (16) is adapted to be movably arranged within the channel (13). The material cartridge (10, 10') is adapted to be removably placed in the rapid prototyping device (100), and the rapid prototyping device (100) can move the support (16) of the material cartridge (10, 10 ' ).
Abstract:
A system for making a dental restoration, comprising a 3D digitizer for producing a 3D model digital representation of a dental restoration model, a computer in communication with the 3D digitizer and capable of creating a dental restoration milling trajectory for a selected block of given dimension and given dental restoration material, based on the 3D model, and a laser milling apparatus in communication with the computer and capable of laser milling the dental restoration from the selected block positioned therein using the milling trajectory created by the computer. The laser milling apparatus includes one or more sensor for continuously monitoring the laser milling of the selected block and to provide feedback to the computer such that the milling trajectory is continuously adjusted by the computer using the feedback from the one or more sensor.
Abstract:
Gemäss einem Aspekt der Erfindung wird ein keramisches Implantat, insbesondere ein Dentalimplantat (1) zur Verfugung gestellt, welches einen keramischen, enossalen Oberflächenbereich aufweist, d.h. einen Bereich, der zur Einbettung ins Knochengewebe bestimmt ist und aus einem keramischen Werkstoff gefertigt ist. Dieser Oberflächenbereich weist mindestens eine erste Region mit einer Oberflächenmodifikation, in welcher die Oberfläche aufgerauht oder porös ist, und mindestens eine zweite Region, in der die Oberfläche nicht aufgerauht oder porös ist, auf.
Abstract:
Systems and methods disclosed herein employ various modes of material deposition and material removal to build a complex, three-dimensional structure upon a rotating base. The systems and methods may be usefully employed to fabricate geometrically and aesthetically accurate dental articles from digital models.
Abstract:
A device and method for forming a texture on a surface of a hard material. Spatial patterns, such as an array of microbeams, are delivered to the tissue through the handpiece. The plurality of microbeams illuminate and ablate the hard material simultaneously. Each of the microbeams has of a sufficient fluence and pulse width to ablate the surface of the hard material and form the texture. Alternatively, one microbeam of a sufficient fluence and pulse width to ablate the surface of the hard material and form the texture is scanned over the surface either manually or in an automatic fashion.
Abstract:
A dental blank of the present invention has at least an inner zone (or layer) of a first color and an outer zone (or layer) of a second color wherein the inner and outer zones are concentric The inner zone can be surrounded in its entirety by the outer zone such that only the outer zone is visible on all surfaces of the blank and the inner zone is not visible on any surface of the blank Alternatively, the inner zone and the outer zone can extend to a same single surface of the blank, such that only the outer zone covers all remaining surfaces The dental blank may also have an intermediate zone between the inner and outer zones, wherein the intermediate zone is surrounded in its entirety by the outer zone and/or the intermediate zone surrounds the inner zone in its entirety.
