A fixation pin for fixing a dental drill template. The fixation pin has a head having a bearing surface that is intended to bear at least partially on the drill template, or a sleeve provided in the drill template. The fixation pin has a rod having a shape of an essentially circular cylinder and extending from the bearing surface at an essentially right angle. The rod is intended to be inserted into the drill template or the sleeve provided in the drill template.

The invention relates to a three-dimensional orthodontic retainer (2) and to a method for producing such a retainer (2) in which the three-dimensional orthodontic retainer (2) is matched to the exact shape of the adjacent teeth (3) and is produced from a blank (1) in such a manner that the physical properties of the material of the remaining part of the blank (1) are unchanged in the retainer (2). The method for producing the three-dimensional orthodontic retainer (2) comprises the following method steps: creating three-dimensional model of the structure of the patient's teeth (3); designing a customised, precisely fitting model of the retainer (2); producing the retainer (2) on the basis of the designed 3D model by computer-controlled deposition or application of material.

A method includes determining depth values associated with a first set of pixel locations in a first image of a mouth. One or more function is generated for one or more color channels based on intensities of the one or more color channels at the first set of pixel locations and depth values associated with the first set of pixel locations. Image data comprising a new representation of the teeth is received, wherein the image data comprises a second set of pixel locations and new depth values associated with the second set of pixel locations. A new image is generated based on the image data and the one or more functions.

A method of making a dental restoration has the step of providing a precursor of the dental restoration. The dental restoration has at least a first and a second surface portion which are delimited by a physical boundary structure. The method further has the steps of applying a first coloring solution associated with the first surface portion onto the first surface portion, sintering the dental restoration precursor, and removing the physical boundary structure.

Orthodontic brackets and methods for the manufacture of orthodontic brackets including identification marks indicating placement, thickness, or torque.

[Problem]

A technique for imparting high translucency which is similar to an enamel of a natural tooth to a zirconia sintered body, has been required.

[Solution]

To provide a zirconia mill blank for dental cutting and machining, containing, an yttrium compound and an indium compound as stabilizers, wherein, an amount of the yttrium compound is within a range of 3.0 mol % to 6.0 mol % in terms of oxide, an amount of the indium compound is within a range of 0.2 mol % to 3.0 mol % in terms of oxide, and a total amount of the yttrium compound and the indium compound is within a range of 5.5 mol % to 7.0 mol % in terms of oxide.

The present invention provides Dental implant configured to be inserted into a hole in jaw bone and to be at least partially situated in bone tissue when implanted, comprising:

a coronal implant region, the surface of which is at least partly covered by an oxide layer with an average thickness in the range from 60 nm to 170 nm and has an average arithmetical mean height Sa in the range from 0.1 μm to 1.0 μm. Further provided is a component for dental applications, preferably dental abutment, wherein the surface of the component is at least partly covered by an oxide layer with an average thickness in the range from 60 nm to 170 nm and has an average arithmetical mean height Sa in the range from 0.05 μm to 0.5 μm and an implant system comprising the dental implant and the component. Method for forming a protective layer on the surface of an implantable or implant component, the method comprising a) applying a solution on the surface of component, the solution having a pH at 25° C. of 6.8 or less and b) drying the solution applied in step a) to form a protective layer on the surface of the component for dental applications. Finally, part of the present invention is an implantable or implant component having a protective layer obtainable as above and a use of such layer for storage.

A blank for milling or grinding a dental article, the blank having a plate-shaped body adapted to be received in a blank holder of a CAM system, which plate-shaped body comprises one or more ceramic or glass ceramic blank portions and two or more through holes, wherein each through hole is contiguous with at least one of the ceramic or glass ceramic blank portions for receiving a working end of a milling or grinding tool of the CAM system.

Disclosed is a pre-sintered ceramic block for a dental restoration, which has a low pre-sintering temperature, contains a silica main crystal phase, but does not contain or contains a small amount of lithium metasilicate crystal phase. The pre-sintered ceramic block has a low hardness, with a Vickers hardness of 0.5-3 GPa, which is significantly lower than that of a ceramic block containing a lithium metasilicate crystal phase, and same is suitable for dry machining and also wet machining when being machined into a dental restoration.
