An injection correction impression tray (18) serves for producing dental impressions for the subsequent manufacture of crowns, bridges and other dental prostheses. The tray (18) includes a base body (23) containing impression material and a profile bottom plate (27). The plate (27) includes a first channel (41) and a second channel (43) being arranged in the bottom side of the plate (27). The plate (27) is connected to the base body (23) in a way to close the bottom opening (6) of the tray (18) and such that the bottom side and the channels (41, 43) face the interior of the base body (23). The first channel (41) forms a rib of a first impression material being introduced into the interior of the base body (23) and flowing through the bottom opening (6) into the first channel (41). The first channel (41) is designed and arranged such that a channel for introducing correction impression material is formed by the first channel (41) and a remainder of the first impression material after the rib of the first impression material has been partly removed.
