Abstract: A microcapsule for use in the treatment of dental malocclusions/misalignments based on plastic splints or aligners. The microcapsule is a few μm, such as 0.5 μm to 200 μm in size and has a shell made of plastic or glass or ceramic, the shell is filled with a liquid in the interior, and the shell breaks open when it experiences a force and releases the liquid, which can be detected optically, for example, by a color change or illumination with UV light.

Abstract: A building plate assembly for use in an additive manufacturing apparatus including means for additively manufacturing a component through curing photocurable resin, the building plate assembly including: a building plate having a front surface on which the component can be attached during the additive manufacturing; a plurality of through holes formed between the rear surface and the front surface of the building plate; further including: a detachment means having one or more projections which can be relatively moved towards the rear surface and into the through-holes to detach the component from the front surface and, retracted to at least partly clear the through-holes. The through-holes and the corresponding projections are arranged in a two-dimensional array.

Abstract: The invention relates to a method (100) and to a corresponding system (1) for providing a dental prosthesis (10) made from ceramic material (2) having a colour matched to the patient comprising the following steps:—receiving (110) a desired nominal colour for the dental prosthesis (10), determining (120) a deviation between the nominal colour and actual colour of the sintered ceramic material (2) by the control unit (4) and defining (130) a temperature time cycle havoing a cycle time (TH), suitable for compensation of the deviation, for sintering at a defined sintering temperature (TS) and creating a corresponding sintering program (5) by the control unit (4); and—adjusting (140) the actual colour of the selected ceramic material (2) to the nominal colour (4) in the sintering furnace (3) by the sintering program (5) executed by the sintering furnace (3).

Abstract: An aligner for use in the treatment of malocclusions/misalignments by using force measurement of the aligner on the teeth. The aligner has at least two referencing features located on it in the initial state. The referencing features are of such a size, about or at least 10 micrometers, that they can be accurately detected by a camera or other means. The referencing features are of an optical or topographic kind.

Abstract: A method for color customization of dental restorations is presented with the steps of providing tooth measurement data, wherein the tooth measurement data comprise at least one insertion area in which the dental restoration is to be inserted, providing restoration data, providing information about staining or glazing colors, generating a color characteristic from the tooth measurement data taking into account the restoration data, and calculating a multicolor target coloration from the color characteristic taking into account the information on staining or glazing colors, as well as output of the multicolor target coloration for color customization of the dental restoration.
