Impression tray for oral cavity

Abstract

The invention discloses an oral cavity impression tray which structurally comprises a connecting concave plate, an impression tray body, a tray handle, an overflow discharging hole, a butt joint buckle, a separating device and a tongue-shaped plate. When the oral cavity impression tray is used, a first supporting plate and a second supporting plate are connected to the connecting position of the connecting concave plate and the bottom of the impression tray body respectively; the butt joint inserting rods on the first supporting plate and the second supporting plate can be buckled with the butt joint buckles in a matched mode, the impression material is pressed on the dentition through cooperation of the connecting concave plate and the impression tray, medical staff can firstly separate the impression material on the connecting concave plate, after separation is completed, the medical staff can press the connecting concave plate downwards, and the impression material on the dentition can be separated. The second supporting plate can drive the connecting concave plate to move downwards to be separated from the impression tray under the action of the second fastener after being subjected to downward pressure, the medical staff can segment the impression material on the impression tray again, and the formed impression is not prone to deformation.

Description

technical field [0001] The invention relates to the technical field of dental medical instruments, in particular to an impression tray for oral cavity.

Problems solved by technology

[0003] When using the impression tray, put the oral impression tray into the mouth, and press the impression material firmly on the dentition. After the impression material hardens, you can get the imprint of the teeth after taking it out from the teeth. Because After the impression material hardens, it will solidify and stick to the tray, so that when the oral impression is removed, the medical staff can quickly separate the impression material on both sides of the impression tray, while the impression material in the middle of the impression tray is separated If you do not pay attention, it may cause bending and deformation in the middle of the formed impression, which will directly affect the accuracy of the impression and increase the workload of medical staff
