The dental impression bite tray comprises: a U-shaped tray body having pad entrances in both sides to attach a pad and having a coupling protrusion formed in one side thereof to fix support pieces in top and bottom sides of the pad entrances； and a handle body having a support piece. In the U-shaped tray body, a hanging unit formed by winding both ends of a disposable pad for accommodating an impression material and a support unit for preventing overflow of an impression material in the center thereof are formed by coupling an extension piece coupling hole formed in an extension piece formed in the center of the pad. The support piece includes a groove for accommodating the hanging unit formed on the pad by being coupled with the pad entrances formed in the U-shaped tray body, and a coupling groove formed to be coupled with the coupling protrusion formed in one side of the U-shaped tray body.
