The present invention relates to a bite tray (2), wherein an upper jaw tray (100) and a lower jaw tray (200) are detachably coupled with each other to constitute one set such that an impression taking procedure is simultaneously performed on the upper jaw and the lower jaw while the upper jaw tray (100) is coupled with the lower jaw tray (200), and a plaster pouring procedure after the impression taking is separately performed on the upper jaw and the lower jaw while the upper jaw tray (100) is detached from the lower jaw tray (200). According to the present invention, the plaster (80) pouring procedure can be performed while the upper jaw tray (100) is detached from the lower jaw tray (200), and thus, a conventional process of first pouring plaster (80) in any one of the upper and lower jaw trays, waiting for the solidification of the plaster, and then pouring plaster (80) in the other need not be gone through. That is, plaster can be poured in both of the upper jaw tray (100) and the lower jaw tray (200), thereby shortening the total time for plaster solidification in both of the trays, compared with the conventional art, and causing no problem in that the heat or volume change occurring from the solidification of the plaster in any one of the trays influences the plaster in the other. Furthermore, the bite tray of the present invention comprises many components for preventing the detachment of an impression material (60) from the bite tray (2) during the impression taking procedure, and thus the impression material (60) need not be excessively used like in the conventional art, thereby reducing the consumption amount of the impression material (60).COPYRIGHT KIPO 2016본 발명은 인상채득(impression taking) 과정은 상악트레이(100)와 하악트레이(200)가 결합된 상태에서 상악과 하악에 대해 동시에 이루어지고, 인상채득 후의 석고를 부어 넣는 과정은 상악트레이(100)와 하악트레이(200)가 분리된 상태에서 상악과 하악에 대해 별도로 이루어질 수 있도록 상악트레이(100)와 하악트레이(200)가 분리가능하게 결합되어 한 세트를 이루는 바이트 트레이(2)에 관한 것이다. 본 발명에 의하면, 석고(80)를 붓는 과정이 상악트레이(100)와 하악트레이(200)가 분리된 상태에서 이루어질 수
