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). The scan head guide (18) passes through the cavity towards the scan head (20). In particular, a control device (44) determines the shape of the cavity (40). A second extraoral scanning head (43) scans extraoral areas.

Abstract: In the case of a dental prosthesis comprising a gum-coloured prosthesis base and a tooth coloured tooth arrangement which is partially embedded into the prosthesis base, the dental prosthesis is formed as a hybrid prosthesis, wherein the prosthesis base has a contact surface which has a surface normal pointing towards the gums. The tooth arrangement (14) surrounds an external telescope (secondary part) or an abutment on at least 2 sides (26, 28, 30), is formed as a one-piece tooth quadrant or as a segmented tooth quadrant (16) and consists of a harder material than the prosthesis base (12).

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.
