The invention relates to an impression tray, such as in particular a
dental impression tray, which carries a deformable impression
mass in order to prepare an impression of arrangements, shapes and / or dimensions, in particular in or on the
human body, preferably in the mouth, and further preferred an impression of at least part of a tooth or of dental structures, wherein furthermore sensor devices are present, by means of which a change of at least one
physical property and / or variable of the impression
mass can be captured in a
spatially resolved manner when preparing an impression and can be provided in a form that is suited for
electronic data processing. The invention further relates to a method for capturing structures, arrangements or shapes, such as preferably for capturing dental structures, arrangements or shapes in the mouth or in the
human body, whereby a deformable impression compound is brought onto or into the structures, arrangements or shapes in particular, is introduced, into the mouth or body and a change of at least one
physical property and / or variable of the impression compound is transmitted there in a
spatially resolved manner directly to sensor devices when preparing an impression and is captured by the sensor devices and, furthermore, provided in a form that is suitable for
electronic data processing.
