Abstract: A dental impression tray which in a modular system can be assembled from a plurality of portions which can be connected together and is thus individually adaptable to the patient jaw situation. There may be a universal base tray with insertable additional parts both for lower jaw and also for upper jaw impressions, wherein further adaptation can be implemented by extension portions and by shortening of the portions on the basis of predetermined markings or desired breaking locations. The impression tray may be a thermoplastic material which can be heated and still more precisely formed to the respective jaw geometry within the patient's mouth.

Abstract: An individually adaptable impression tray for dental fine impression is formed substantially from a thermoplastic material which in the heated state permits adaptive forming of the impression tray in the mouth of a patient. At least in partial regions in which a fine impression is to be made the impression tray has a spacer layer of a predetermined thickness, wherein the spacer layer is completely or partially removable after the forming operation.
