An apparatus serves to produce dental impressions for the subsequent manufacture of crowns, bridges and other dental prostheses. The apparatus serves to produce so called injection correction impressions of teeth contained in a jaw. The apparatus includes an injection correction impression tray having an interior for containing impression material. The tray includes a bottom opening. The apparatus further includes a bottom plate having a top side and a protrusion. The bottom plate is connectable to the tray in a way that the protrusion protrudes into the interior of the tray to form an injection channel for a correction impression material.
