The invention relates to a single- or multi-unit dental restoration, which consists of a support structure and a veneer, which support structure is in particular made from oxide ceramics by means of additive manufacturing, particularly preferably by means of rapid prototyping, wherein the veneer is produced by pressing a ceramic material, such as a glass ceramic or composite material, which is more translucent than the support structure, characterized in that the veneer fills and/or penetrates recesses of the support structure (12) configured as a net or frame structure or as a reinforcement, wherein it is particularly provided that the recesses penetrate through the support structure (12).

There is provided at least any of a layered body which has a change in color tone and in which it is unnecessary to select a colorant and the content of the colorant in consideration of a difference in the sintering behavior between layers, a precursor thereof, or a method for producing these. Provided is a layered body which has a structure, in which two or more layers containing stabilizer-containing zirconia and a colorant are layered, and in which types and contents of the colorants contained in the layers are equal to each other, the layered body including at least: a first layer containing a colorant and zirconia which has a stabilizer content of higher than or equal to 3.3 mol %; and a second layer containing a colorant and zirconia which has a stabilizer content different from that of the zirconia contained in the first layer.

A method for defining at least one boundary surface inside an artificial tooth element, the method comprising the steps of: aligning the tooth element with a coordinate system which preferably relates to anatomically defined directional terms; defining a first boundary curve on the tooth surface; determining a tooth surface located incisally/occlusally with respect to the first boundary curve; and moving this tooth surface inwards in the direction of the surface normal by different amounts in order to produce the at least one boundary surface, in particular the first boundary surface, wherein the different amounts of the movement involve variable design parameters.

A dental multi-colored milling blank having at least two layers (16), a transition zone, where material from both layers is present. In the transition zone, a transition geometry exists that extends three-dimensionally. The transition geometry comprises round surfaces facing towards both directions of extension of the layers.

A virtual model of an intraoral cavity is provided, wherein this process is initialized by a dental clinic, and the design and manufacture of a suitable dental prosthesis for the intraoral cavity is shared between a dental lab and a service center.

A custom tool for forming a dental restoration in a mouth of a patient includes a mold body providing for a customized fit with at least one tooth of the patient. The mold body includes a facial portion forming a facial surface corresponding with a facial surface of the tooth, and a separate lingual portion forming a lingual surface corresponding with a lingual surface of the tooth. The mold body is configured to combine with the tooth of the patient to form a mold cavity encompassing missing tooth structure of the tooth.

The invention relates to a polymerization and post-tempering device (10) for tempering, in particular post-tempering, dental restoration parts (54) made of polymerizable plastics. At least one light source (38) which emits light in the visible and/or ultraviolet wavelength range and a light chamber with a door (14) to the light chamber are provided. The door (14) comprises a window (20) with a window pane (22) which consists of at least two layers (56, 58) whose layer facing the light chamber reflects at least 90%, in particular approximately 95%, of light, and whose layer facing away from the light chamber filters out UV light and/or blue light.
