[0020] Combination Figure 1-Figure 2 As shown, a dental plate protective cover comprises a first film layer 10 and a second film layer 20; the adjacent edges of the first film layer 10 are arc-shaped transitions; at least three sides of the second film layer 20 are integrally bonded to the edges of the first film layer 10, and form a chamber 1 with one end closed and the other end open, and the chamber 1 can hold a dental plate; the first film layer 10 comprises a first light-shielding section 11, a second light-shielding section 12, and a light-transmitting section 13; the first light-shielding section 11 and the second light-shielding section 12 are respectively arranged at the two ends of the first film layer 10 along the length direction, and the light-transmitting section 13 is arranged between the first light-shielding section 11 and the second light-shielding section 12.

[0021] The dental film protective cover in the present application is mainly used in the environment where the dental film is placed when the patient's teeth are filmed, and its outer wall is usually in contact with the patient's oral surface or gum surface. The dental film protective cover in the present application is composed of a first film layer 10 and a second film layer 20. The arc transition of the adjacent edges of the first film layer 10 avoids scratching or rubbing the patient's mouth due to the flat peripheral surface. The edge of the first film layer 10 and at least three sides of the second film layer 20 are integrally bonded to form an independent open chamber 1 for placing and removing the dental film. The setting of the first shading section 11 and the second shading section 12 can ensure that the dental film can effectively map the health of the patient's tooth surface during the filming process. The setting of the light-transmitting section 13 is to provide a scattered light source for the dental film on the one hand, and on the other hand, to separate the first shading section 11 and the second shading section 12 to ensure the authenticity of the tooth surface film.

[0022] A concave structure 30 is provided on one side of the first film layer 10 and the second film layer 20 near the closed end of the chamber 1, and the bottom of the concave structure 30 is close to the closed end of the chamber 1. The setting of the concave structure allows the staff to directly tear open the first film layer 10 and the second film layer 20 and take out the dental piece, thereby preventing the staff from inserting their fingers into the chamber 1 to clamp out the dental piece, resulting in black spots on the test results of the dental piece.

[0023] The dental film in the present application is placed in the area of ​​the first light-shielding section 11. To ensure that the dental film can effectively cover the patient's tooth surface during the filming process and that the dental film can be completely mapped to the light source, the length of the first light-shielding section 11 is greater than the length of the second light-shielding section 12, and the length of the first light-shielding section 11 is greater than the length of the dental film.

[0024] The joint of the first film layer 10 and the second film layer 20 is vertically extended from the outer end surface and evenly distributed with convex strips 40. The setting of the convex strips 40, on the one hand, ensures that the staff can stably take the tooth piece protective cover of the present application to avoid falling to the ground and contaminating the surface of the tooth piece protective cover of the present application; on the other hand, it increases the friction between the tooth surface and the tooth piece protective cover to ensure stable contact between the tooth and the surface of the first film layer 10 and the second film layer 20.

[0025] The two sides of the light-transmitting section 13 along the width are smooth, and the end of the light-transmitting section 13 away from the first light-shielding section 11 can move closer to or farther away from the first light-shielding section 11. The side of the light-transmitting section 13 of the present application is smooth, and the purpose of such a setting is to be able to bend the second light-shielding section 12 toward one side of the first light-shielding section 11, thereby constraining the tooth piece within the light-shielding area of ​​the first light-shielding section 11, and preventing the tooth piece from shifting within the first light-shielding section 11.

[0026] To ensure that light can normally pass through the second film layer 20 and reflect from the surface of the first film layer 10 during the dental film shooting process, the second film layer 20 is made of a transparent material. The transparent second film layer 20 can be made of polyethylene or polystyrene, and the material of the second film layer 20 is not limited in this application.

[0027] The material of the dental film protective cover in the present application is one or more of silica gel, agar, high molecular weight sodium polyacrylate and repeatedly frozen and thawed polyvinyl alcohol gel, and a combination of different materials is used to maximize the economy. In order to avoid scratching the patient's soft tissue during the patient's dental radiograph, the edges of the sleeve formed by the bonding of the first film layer 10 and the second film layer 20 in the present application are all arc transitions, so that the edges of the formed dental film protective cover are more rounded.

[0028] It should be further explained that the size of the dental plate stored in the dental plate protective cover in the present application is 4×3cm. In order to well protect the dental plate, the size of the dental plate protective cover in the present application is designed to be 4.5×3.5cm. The specific size of the dental plate protective cover is not limited in this application. Those skilled in the art can choose dental plate protective covers of different sizes to suit dental plates of different sizes according to specific circumstances.

[0029] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0030] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
