The present invention provides a plastic dental impression acquisition bite tray having a metallic reinforcement inserted into a central connection link and a body area of an impression acquisition frame and in particular, a dental impression acquisition bite tray in which the top, bottom, left and right walls of the impression acquisition frame are divided into plural parts at regular intervals with respect to an impression acquisition film such that the profile of the plastic dental impression acquisition bite tray is adaptively bent little by little in correspondence with the curvature of teeth alignment, thereby enabling the acquisition of an impression of any type of teeth. The plastic dental impression acquisition bite tray, having a handle to be held by an impression acquirer and an impression acquisition frame provided at one side of the handle, the impression acquisition frame being formed of a wall to support an impression material from the side during the acquisition of an impression, comprises: an impression acquisition film provided at the central portion of the impression acquisition frame, for providing a space to receive an impression material for the acquisition of an impression and a metallic reinforcement inserted into a central connection link and the impression acquisition frame, wherein the top, bottom, left and right walls of the impression acquisition frame are divided into plural parts at regular intervals such that all or part of the profile of the dental impression acquisition tray can be freely deformed through adaptive bending by degrees to be in correspondence with the curvature of teeth alignment, thereby enabling the acquisition of an impression of any type of teeth.
