Abstract: The invention relates to a furnace having a vertical orientation for dental components, comprising a combustion chamber, which is open at the bottom and the opening of which can be closed by means of a furnace door, which is lowered in the vertical direction in the open position, and comprising a depositing region for the heated component, which depositing region is arranged at a distance from the opening in the combustion chamber. The depositing region is part of the furnace, and a cooling device that acts on the depositing region is arranged on or in the furnace. A heat-resistant base has a heat-resistant support arranged in a housing, which support has an active or passive cooling device, which, for example, has a Peltier element.

Abstract: An extraoral dental scanner for three-dimensional capture of the surface of a dental shaped part (300) with a 3D measuring camera (102) having an optical axis (106), wherein the means for the machine-controlled relative positioning of the 3D measuring camera (102) and the dental shaped part (300) are embodied in such a way that the means for taking up and positioning the dental shaped part (300) can be moved into a parking position outside a region that can be captured optically by the 3D measuring camera (102), with a work plate (708) for manually positioning the dental shaped part (300) in the measurement volume (144) of the 3D measuring camera (102), wherein the work plate (708) is aligned perpendicularly to the optical axis (106) and wherein the work plate (708), as viewed from the 3D measuring camera (102), is arranged behind the means for taking up and positioning the dental shaped part (300), makes it possible to record uninterrupted 3D image data with very short recording times both by automatic and by manual positioning of dental shaped parts of different sizes and embodiment variants.
