Abstract
The invention relates to a dental impression tray comprising a base and at least two walls defining said base. At least one of these walls is at least partially formed by hollow bodies made of flexible material. Said hollow bodies can be filled in order to form, when taut, the desired shape for using the mould tray. In order to provide sufficient longitudinal stability for the impression tray, at least one of the walls is fitted with a rigid longitudinal rib. Said wall can also be rigid in its entirety. The hollow bodies which are to be filled can be fitted with openings. The moulding material filling the hollow bodies can flow from said openings into the moulding region of the dental impression tray. The base is flexible.
