A bendable impression tray includes a base portion and a handle portion. In one embodiment, the bendable impression tray includes a U-shaped portion and at least three projections extending outwardly from the U-shaped portion by at least 5 millimeters in bottom view. In one embodiment, the bendable impression tray includes a base portion that is substantially U-shaped in bottom view, and defines at least two peripheral notches, each extending inwardly from an outer periphery of the base portion by at least 5 millimeters in bottom view.

A cap mountable on and detachable from an intraoral scanner including a housing having an opening for connecting to at least a part of the intraoral scanner, a measurement window provided in the housing and located opposite to the opening, and a mirror that reflects light from the measurement window toward the opening. The housing has a longitudinal length shorter than that of a probe defining a depth-of-field, of the intraoral scanner extending from the measurement window to a predetermined extent.

A method of producing a dental restoration, including the steps of producing (S101) the dental restoration in an initial geometry having an excess volume compared to the final geometry to be produced; infiltrating (S102) the initial geometry with an investment material; and removing (S103) the excess volume with the investment material to produce the final geometry.

A system includes an optical probe with a sensing face. The optical probe to emit optical signals and receive reflected optical signals. The system includes a computing device, coupled to the optical probe, to receive intraoral scan data of a tooth. The intraoral scan data includes first optical scan data and second optical scan data. The computing device to process the received intraoral scan data to adjust the first optical scan data associated with a sub-gingival surface of the tooth based on the second optical scan data associated with a material covering the sub-gingival surface of the tooth. The computing device to generate a three-dimensional model that includes the sub-gingival surface of the tooth using the adjusted first optical scan data that is associated with the sub-gingival surface of the tooth.

A method of producing a dental object (100), including the steps of producing a pillared support structure (101) on the dental object (100); and producing a lattice structure (103) for reinforcing the support structure (101).

A dental milling machine comprising a workpiece holder (2) and a changer arm (10) is characterized in that the changer arm (10) has a substantially U-shaped gripping attachment (12) and in that a tool (14) of the dental milling machine (1) has a tool fixation element (16). The tool fixation element has grooves (18) or holding projections at two mutually opposed positions which face away from each other, over which grooves or holding projections the U-shaped gripping attachment (12) of the changer arm (10) can engage, wherein parts of the U-shaped gripping attachment (12), more particularly the side flanks (12a, 12b) of the U-shaped gripping attachment (12), make contact with the grooves (18) or holding projections of the tool fixation element (16) under preload.

The invention relates to a dental machining unit (1) having a milling chamber (10), wherein the workpiece arm (22) passes through a movement flange (24) at which the workpiece arm (22) passes through a passage wall (25) of the milling chamber (10), and that the passage wall (25) comprises a membrane (26) which permits movement of the workpiece arm (22) in at least two spatial directions and consists of a highly elastic material and particularly comprises corrugations (28).

The present invention relates to an implantable medical device comprising a layer consisting of or comprising zirconia, and to a method for the preparation thereof.

Quartz solid solution glass ceramics and precursors thereof are described. which are characterized by very good mechanical and optical properties and can be used in particular as restorative materials in dentistry.

A resin block suitable for dental cutting work may include a resin matrix (A) and spherical filler (B) whose average particle size ranges from 230 to 1000 nm. When 10 mm thick and measured with a colorimeter, the lightness (V) is less than 5.0 and the saturation (C) is less than 2.0 in a Munsell color system of colored light on a black background and a white background. When 1 mm thick, the lightness (V) is less than 5.0 and the saturation (C) is 0.05 or more on a black background, but on a white background, the lightness (V) is 6.0 or more and the saturation (C) is less than 2.0 for Munsell colored light. Resin blocks can be used for dental restoration such that dental prostheses produced from the block not using a pigment/dye are compatible with natural teeth color tone, and the color tone compatibility endures.
