Abstract: A mixer for mixing a dental composition comprises a mixer housing with a wall of the mixer housing forming a light filter. The light filter provides for substantially blocking light of certain wavelengths, whereas it transmits light of at least some other wavelengths. The invention may help to prevent dental compositions from degrading.

Abstract: A method in the preparation of a dental restoration, in which the dental restoration has an implant unit and a head structure interconnectible with one another, comprises the steps of providing an auxiliary material, providing a computerized head receiving surface representation (A?), manufacturing from the auxiliary material a measuring element having a measuring surface (M) and an implant unit coupling surface (X). The measuring surface (M) is adapted such that it can be captured by an optical measuring device, and the measuring element coupling surface (X) is adapted for mating with the head receiving surface (A). The method may help making the preparation of a dental restoration more time and cost efficient.

Abstract: Provided is a capsule for storing and dispensing dental material. The capsule comprises a cartridge for the dental material, and a nozzle. The nozzle being pivotable with respect to the cartridge between a first position in which the capsule is closed for storage and a second position in which the capsule is opened for dispensing the dental material. One of the nozzle and the cartridge comprises a bearing member and the other one of the nozzle and the cartridge comprises a bearing shell, wherein the bearing member and bearing shell form a pivot. Upon pivoting the nozzle from the first to the second position, the seal between the bearing member and the bearing shell is improved.

Abstract: A method of making a dental restoration comprises steps of transmitting from a scanning device scan data to a central processing unit and receiving on a Computer Numerical Control (CNC) device machine control data for manufacturing a dental restoration from the central processing unit. The machine control data are associated with the scan data. Further the scanning device and the CNC device are at the same first location, whereas the central processing unit is at a different second location remote from the first. The method further comprises steps of providing a dental blank and shaping the dental blank based on the machine control data to provide the dental restoration. The method and a system for performing the method help maximizing the timely efficiency in a restoration of a tooth and helps maximizing the quality of a chairside manufactured dental restoration.

Abstract: A method of making a dental workpiece is provided. The method comprises the steps of suspending machining of the workpiece, exposing the workpiece to a first air jet; and causing relative movement between the first air jet and the workpiece under numeric control. The method may facilitate manufacturing of dental workpieces.

Abstract: The invention includes a support frame for producing a dental workpiece. The frame has a Z axis and comprising wall sections defining a hole that extends along the Z axis through the frame. At least one of the wall sections comprises an adhesive-directing surface extending along the Z axis in a non-parallel relationship. Such a configuration provides optimized methods for affixing a blank to the support frame and optimized properties of the blank after fixation to the support frame.

Abstract: A nozzle head (5) for a powder jet device (1), for use in applying dental material, comprises a first fluid flow path (8) for delivering a powder/fluid mixture to a first discharge nozzle (8A). A second fluid flow path (6) is provided for delivering a liquid to a second discharge nozzle (6A) located adjacent the first discharge nozzle (8A), so that the materials discharged by the first and second discharge nozzles combine at a desired location to form a dental composition. A nozzle-clearing member (10) is located inside the nozzle head and is movable to remove powder material from the first discharge nozzle when the flow of powder/fluid mixture to the nozzle ceases.

Abstract: In one embodiment, a system for making a dental restoration is provided. The system includes a machine unit for processing a dental material to form the dental restoration, and a control unit for controlling the operation of the machine unit. An air channel for discharging a process-originated material from the machine unit provides an air connection between the machine unit and the control unit. Certain embodiments of invention are advantageous in that they help to increase the reliability of the machining operation.
