ABSTRACT OF THE DISCLOSURE A combined dental impression tray with a syringe is provided, wherein the communication between the syringe and the tray is effected, in the most preferred embodiment, by way of a side opening in the wall of the barrel of the syringe. The opening communicates with the bottom section of the tray and is very short compared to the diameter or cross-sectional area of the passage for the impression material. The opening is arranged such that it can be closed by the piston of the syringe while a first impression of the tissue area is taken. A device detachably secured to the tray apparatus is also provided to facilitate cutting out of a portion of the dental mixture, the cutting device being preferably of the type of a reciprocating tubular cutting die whose edge engages the bottom wall of the tray at a close spacing about the said opening. The advance in the art is in an arrangement which avoids any narrow passages between the syringe and the tray or channels difficult to clean and causing entrapment of air bubbles which may result in a reduced quality of the impression.
