Abstract: The invention relates to a recording device (10) comprising a scan head carrier (18) for moving the scan head (20) across a scan area (42) of a cavity, the scan area (42) extending around the scan head (20). A flat or film-like, elastically stretchable material extends between the scan head (20) and the scan area (42), which material can be pressed against the scan area (42) in a balloon (12)-type manner using overpressure. The scan head guide (18) passes through the balloon outlet (16) of the balloon (12) towards the scan head (20). In particular, a control device (44) determines the shape of the cavity (40) against which the material is pressed, from deformation of the material when applying said overpressure. A second extraoral scanning head (43) scans deformations during pressurization of the film-like material.

Abstract: A system of a dental restoration part or several dental restoration parts, and/or with a dental restoration part which is possibly embedded in a muffle, and a cooling device is provided. The cooling device comprises cooling bodies as bulk material and a movement device by means of which cooling bodies and the dental restoration part(s) may be moved relative to one another.

Abstract: The invention relates to an image-recording device (10), comprising a scanning-head guide (18) for moving the scanning head (20) across a scanning region (42) of a cavity, which scanning region (42) extends around the scanning head (20). A planar or film-like, elastically extensible material extends between the scanning head (20) and the scanning region (42), which material can be pressed against the scanning region (42) by the application of overpressure in the manner of a balloon (12). The scanning-head guide (18) extends through the balloon connection (16) of the balloon (12) to the scanning head (20). In particular, a control device (32) determines the shape of the cavity (40) against which the material rests from the deformation of the material while the overpressure is present.
