The invention relates to an adaptation system (), comprising a mouthpiece (), configured to be positioned in a mouth of a person, and an external sensoring device (). The external sensoring device () is configured to be positioned at the person, wherein the external sensoring device () comprises at least one sensor () configured to sense at least one measurable quantity when the mouthpiece () is positioned in the person's mouth and the external sensoring device () is positioned at the person. Further, the adaptation system () comprises an analysis device () configured to determine a compliance of the adaptation system and/or to determine an orientation of an upper jaw () and a lower jaw () to each other derived from the at least one sensed measurable quantity.

This disclosure relates to a milling blank for the production of medical-technical molded parts, in particular dental splints or ear molds, as well as a method for the production of such a blank.

Milling blank for the production of medical-technical molded parts

A milling blank for producing medical-technical molded parts made from a material produced from at least two components, wherein a first component A comprises a poly(alkyl methacrylate) polymer, and wherein a second component B comprises at least one alkyl acrylate monomere and/or one alkyl methacrylate monomer, in which the poly(alkyl methacrylate) polymer of component A is at least partially soluble, wherein the material comprises a flexibilizer as a further component, wherein the flexibilizer is selected from the group of citric-acid-based, adipic-acid-based, phthalic-acid-based or aliphatic esters.

The invention relates to a device and to a method for the production of a three-dimensional object by the consecutive layered bonding of a material that can be bonded by means of electromagnetic radiation, wherein in the so-called vat an at least n-phase system, where n&#x3e;2, is present, of which at least one phase comprises the building material and at least one other a phase that cannot be mixed with the building material.

Device and method for the generative production of three-dimensional objects on the basis of a multiphase system

A dental modal for making a dental prosthesis has a base body formed with model teeth and model gingiva and with a cutout in an edentate area and with a hole in a floor of the cutout. A plate is releasably fittable complementarily in the cutout and is formed with a hole aligned with the hole of the cutout. A gingiva mask is fittable on the plate in the cutout and is in turn formed with a hole aligned with the holes of the plate and of the cutout. A model implant insert is releasably fittable in the holes of the mask, plate, and cutout and carries a model implant or an implant-screw mockup.
