jaw impression tray

Abstract

According to the present invention there is disclosed an impression tray for mandibular made of plastic, which can prevent solidified impression material from floating up and peeling off from the tray, and can be used to make a high-precision impression. In the plastic impression tray for the mandible, the impression tray has an outer wall (2) and an inner wall (3) in the outer side and inner side of the bottom (1) forming a U-shaped flat surface with an approximately uniform width, along the outer wall ( 2) and each upper end of the inner wall (3) is provided with a flange (4) with a specific height in the bottom (1) side, from the part directly below the flange (4) perpendicular to the flange (4) to the bottom ( 1), the through holes (5) having a specific length and being formed as elongated holes are arranged so that the distance between adjacent through holes (5) is a specific multiple of the width of the through holes (5), at the bottom (1 ) in the center of the adjacent distance of the elongated through hole (5) is provided with a circular through hole (6) with a specific diameter, and at the side where the connection is located closest to the end of the U-shaped part and is formed as On the line of the bottom side end of the through hole (5) of the elongated hole, or in the side closer to the end than the line, a bottom through hole (7) is provided, and the bottom through hole (7) has A specific width and a specific length and is formed as an elongated hole.
