[Industrial applications]

 The present invention relates to an aluminum dental impression tray.

[0002]

[Prior art]

 Conventionally, there have been dental impression trays that use press-molded aluminum, but in the process of manufacturing the impression-maintaining part, the aluminum plate is curved by press-drawing and then used for maintaining the impression material. I was making a hole. However, since the aluminum plate itself was not already flat at the drilling stage, drilling was not easy and there were many processes. Alternatively, even if a hole was opened before bending, the hole was extremely deformed when drawn, so it was not bent enough to form a sufficient angle, and a shape suitable for the oral cavity could not be obtained.

[0003]

[Problems to be solved by the device]

 The present invention is a process of manufacturing an impression maintaining part, in which a hole for maintaining an impression agent is formed by a press die process before the aluminum plate is curved, and the aluminum plate is curved to an angle suitable for the oral cavity. It aims to reduce the number of manufacturing steps, reduce the cost of this product, and lower the selling price.

[0004]

[Means for Solving the Problems]

 (A) Cut a soft aluminum plate into a suitable shape by press die processing. (B) In the process of (c) afterwards, a large number of holes for maintaining the impression material are pre-drilled in places where the holes are not extremely deformed or the aluminum plate is not torn from it. The aluminum plate with holes in the steps (c) and (b) is bent into a shape suitable for the oral cavity by press die drawing.

[0005]

[Operation] Since the present invention has the structure as described above, since the aluminum plate is a flat surface during the drilling process, all the holes can be processed by the press die machining only in one direction perpendicular to the flat surface. It can be opened at once. As a result, holes must be drilled in multiple directions (almost perpendicular to the plane and at an angle that does not burden the drill) depending on the position of the hole to be drilled in the already curved surface as in the past. Needless to say, the number of manufacturing steps and the number of dies for press die processing are reduced, and it becomes possible to reduce the selling price as a product. Further, in the conventional method, the aluminum plate is bent by the press die drawing and then the hole for maintaining the impression material is formed.Therefore, even after the plate is bent, the aluminum plate can be bent only to the extent that the drilling work is possible. However, it was not possible to make a shape suitable for the oral cavity, which should be the shape of the impression maintaining part of the impression tray, but the method of the present proposal was more suitable for the oral cavity by the same press die drawing process as the conventional method. It is possible to bend it into a shape and make an ideal impression tray.

【Example】

 In implementing the present invention, the following can be done. (B) Make a hole for maintaining impression in the aluminum plate used for the impression maintaining part, bend it by press die machining, and then add a hole for maintaining impression. (B) Fix the impression maintaining unit 1 and the handle 2 with the screw 3. (C) Weld the impression maintaining part 1 and the handle 2.

[0007]

[Effect of device]

 Therefore, it is possible to sell aluminum trays that are highly accurate and easy to handle in terms of disinfection, etc., at a lower price than before.

Claims (1)

[Scope of utility model registration request] 1. A dental impression tray using a press-molded aluminum plate as an impression-maintaining portion, for pre-impression-maintaining at a position where a hole is not crushed when the impression-maintaining portion is bent by press-mold drawing. It is made by bending the impression maintaining part to an angle suitable for the oral cavity by punching a hole in the.
