EXTRAORAL DENTAL SCANNER

摘要

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.

主权项

1. Extraoral dental scanner for the three-dimensional capture of the surface of a dental shaped part having:
a) a 3D measuring camera for the three-dimensional capture of the surface of the dental shaped part in a measurement volume of the 3D measurement camera, the 3D measurement camera having an optical axis; b) means for holding and positioning the dental shaped part; b) means for the relative positioning of the 3D measurement camera and of the dental shaped part; c) the means for the machine-controlled relative positioning of the 3D measurement camera and of the dental shaped part being designed such that the means for holding and positioning the dental shaped part can be moved into a parking position outside a region which can be optically captured by the 3D measurement camera; d) a work plate for manual positioning of the dental shaped part within the measurement volume of the 3D measurement camera, d1) the work plate being aligned perpendicularly to the optical axis and d2) the work plate as seen from the 3D measurement camera being arranged behind the means for holding and positioning the dental shaped part.
