The invention relates to a method for producing a monolithic form body, in particular a dental restoration, comprising the steps of: providing of a blank, producing of the form body through pressing and/or machining of the blank, and softening of the form body exclusively in its surface region by irradiation with infrared radiation.

An additively manufactured dental crown with a wall having a bottom edge and an occlusal portion joined with the wall opposite the bottom edge. The wall and occlusal portion form an interior surface and an opposing exterior surface. By using additive manufacturing and materials for such, the dental crown can have thin walls with a thickness of less than 300 microns at the thinnest portion of it and can include fine printed features such as identifiers, internal ribs, slots, porous meshes, and retention elements.

The invention relates to a method for constructing a restoration (1), in which a dental situation (3) is measured by means of a dental camera (2) and a 3D model (4) of the dental situation (3) is generated. In this case, a computer-assisted detection algorithm is applied to the 3D model (4) of the dental situation (3), wherein a type of restoration (17) and/or at least a tooth number (18) and/or a position of the restoration (1) to be inserted are automatically determined.

A computer-implemented method for generating a virtual depiction of an orthodontic treatment of a patient is disclosed herein. The computer-implemented method may involve gathering a three-dimensional (3D) model modeling the patient's dentition at a specific treatment stage of an orthodontic treatment plan. An image of the patient's face and dentition may be gathered. A first set of reference points modeled on the 3D model of the patient's dentition and a second set of reference points represented on the dentition of the image of the patient may be received. The image of the patient's dentition may be projected into a 3D space to create a projected 3D model of the image of the patient's dentition. Based on a comparison of the first reference points and projections of the second set of reference points, a plurality of modified images of the patient may be constructed to depict progressive stages of a treatment plan.

A dental all-ceramic restoration and manufacturing method thereof; the outer surface of the dental all-ceramic restoration has neither visible marks remaining from the removal of the connecting bars (7) nor local grinding traces and chipping, and is smooth with uniform structure. The manufacturing method thereof is wet-forming or milling. No connecting bars are needed to connect the dental restoration bodies (3) with a surrounding mould blank or ceramic blank. This eliminates the need for manually cutting off the connecting bars (7) to separate the forming body from the surrounding ceramic blank, further grinding and polishing process to treat the excessively rough outer surface, and thereby reducing the risk of chipping and premature failure. In the manufacturing processes thereof, the hardened ceramic green body (2) made by wet-forming technique has more homogenous microstructure and less particle packing defects than the dry-pressed blanks and partially sintered blanks. Furthermore, higher surface smoothness can be obtained by milling unsintered hardened ceramic green body than by milling partially sintered blanks. The dental all-ceramic restoration has a high degree of surface finish, and can be directly used without polishing, veneering or glazing.

A matrix adapted is for the specific tooth type, and is positioned on the tooth to covers the tooth, so that an injected curable material is encased by the matrix over the tooth. When the curable material has cured, the matrix is removed, resulting in a veneer on the tooth.
