To provide a dental impression tray for preventing gap formation in an impression material.
The dental impression tray has a wall member 14. When the tray is used, the wall member 14 is disposed facing to the jaw inside the tray, opposite to the dental arches facing the palate or the tongue respectively, and forms a fluid surface 26 for leading an impression material 25 into a region between teeth 21 or low teeth 22 and the gum. Therefore, gap formation in the coagulated impression material is prevented.
