A black triangle repair molding piece

Abstract

This invention provides a black triangular restorative patch, comprising an elastically molded patch body. Two sides of the elastically molded patch body are bent to form a covering body. The covering body has injection holes suitable for injecting fluid resin. A traction and pressing wing extends from the outer side of the covering body away from the patch body, with the outer side of the traction and pressing wing extending outwards towards the covering body and the inner side extending inwards towards the covering body. This invention not only allows the patch to fit more tightly against the tooth but also minimizes the gap between the inner side of the traction and pressing wing and the edge of the affected tooth. This ensures a tight seal with the edge of the affected tooth after resin injection, preventing the resin from forming a protrusion and creating a smooth transition. This reduces the workload of subsequent polishing. Furthermore, the resin injection holes on the covering body avoid the problem of resin being introduced through the labial side of the patch, as is common in existing methods. Polishing only requires removing the resin corresponding to the injection hole, improving restorative efficiency.

Description

Technical Field

[0001] This utility model relates to the field of oral medical device technology, specifically to a black triangle repair molding piece. Background Technology

[0002] "Black triangles" on teeth are gaps formed at the neck of adjacent teeth due to gingival papilla recession. Most black triangles are caused by tartar buildup compressing the gums and gum recession, but many are also due to gingival recession with age. Black triangles are both a pathological and age-related change; they are related not only to oral hygiene and age but also to tooth morphology. Studies show that the occurrence of black triangles is closely related to the distance between the proximal contact point and the alveolar ridge crest. If this distance is greater than 5mm, a black triangle will almost certainly appear. Because the proximal contact point of triangular-shaped incisors is closer to the incisal edge, triangular-shaped incisors are more prone to developing black triangles.

[0003] Generally, black triangles on teeth are difficult to reverse on their own, especially in adults. Although plaque and tartar can be thoroughly removed through professional cleaning, gum tissue has difficulty regenerating completely, making full recovery of black triangles challenging. Currently, the main methods for repairing black triangles are: First, improving tooth shape through interproximal enamel reduction and closing gaps using orthodontic methods to improve or eliminate the black triangles; second, eliminating black triangles using veneers; and third, eliminating black triangles using resin restorations. Because resin restorations require less tooth reduction and are less expensive, they have become the first choice for many.

[0004] The steps for resin restoration of black triangles are as follows: First, clean and polish the relevant teeth. Then, place a pair of black triangle molding pieces of the corresponding size in the interproximal space. That is, place the molding pieces on the adjacent teeth on both sides of the tooth. Then, implant the resin into the molding pieces, light-cur it, remove the molding pieces, and polish.

[0005] The inventors of this application discovered through clinical restorative research that in existing methods of resin restoration of black triangles, the resin is removed by peeling off the labial side of the molded piece, resulting in a raised and uneven contact area between the resin and the tooth edge, which increases the amount of subsequent polishing work and reduces the restoration efficiency. Utility Model Content

[0006] In response to the technical problem that existing methods for repairing black triangles with resin involve peeling off the labial side of the molded piece to release the resin, resulting in a raised and uneven contact area between the resin and the tooth, which increases the amount of subsequent polishing work and leads to low repair efficiency, this utility model provides a molded piece for repairing black triangles.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A black triangular repair molding sheet includes an elastic molding sheet body, with two sides of the elastic molding sheet body bent to form a covering body. The covering body has an injection hole suitable for injecting fluid resin. A traction and pressing wing extends from the outer side of the covering body away from the elastic molding sheet body. The outer side of the traction and pressing wing extends outward from the covering body, and the inner side of the traction and pressing wing extends inward from the covering body.

[0009] Compared with existing technologies, the black triangular restorative molding piece provided by this utility model is used by holding the elastic molding piece and placing it in the interproximal space of adjacent teeth. The covering body covers more than half of the buccal and lingual teeth. The two traction and pressing wings extending outward from the covering body are clamped with clamps and pulled away from the elastic molding piece. This not only allows the molding piece to fit more tightly to the teeth, but also applies pressure to the inner surfaces of the traction and pressing wings extending inward from the covering body during the pulling process. This minimizes the gap between the inner surfaces of the traction and pressing wings and the edge of the affected tooth, allowing for a tight fit with the edge of the affected tooth after resin injection. This prevents the resin from forming a protrusion between the resin and the edge of the affected tooth, resulting in a smooth transition and saving on subsequent polishing work. At the same time, by opening a resin injection hole in the covering body, the problem of resin entering from the labial side of the molding piece can be avoided. In subsequent processing, only the resin corresponding to the injection hole needs to be removed and polished, thus effectively improving the restoration efficiency.

[0010] Furthermore, the elastic molded sheet is made of elastic silicone or elastic plastic.

[0011] Furthermore, a shank is formed on the top of the elastically molded sheet.

[0012] Furthermore, the injection hole is located in the upper part of the coating.

[0013] Furthermore, the pulling and pressing wing has multiple clamping holes horizontally formed on it. Attached Figure Description

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Please refer to Figure 1 As shown, this utility model provides a black triangular restorative patch, including an elastically molded patch body 1. Two sides of the elastically molded patch body 1 are bent to form a covering body 2. The covering body 2 has an injection hole 21 suitable for injecting fluid resin. A traction and pressing wing 3 extends from the outer side of the covering body 2 away from the elastically molded patch body 1. The outer surface 31 of the traction and pressing wing 3 extends outward from the covering body 2, and the inner surface 32 of the traction and pressing wing 3 extends inward from the covering body 2. The outer surface 31 of the traction and pressing wing 3 extends outward from the covering body 2 to facilitate clamping the outer surface of the traction and pressing wing 3 with clamps for traction of the entire patch. The inner surface 32 of the traction and pressing wing 3 extends inward from the covering body 2 so that after traction of the entire patch, the inner surface 32 of the traction and pressing wing 3 can fit more closely to the edge of the affected tooth.

[0020] Compared with existing technologies, the black triangular restorative molding piece provided by this utility model is used by holding the elastic molding piece and placing it in the interproximal space of adjacent teeth. The covering body covers more than half of the buccal and lingual teeth. The two traction and pressing wings extending outward from the covering body are clamped with clamps and pulled away from the elastic molding piece. This not only allows the molding piece to fit more tightly to the teeth, but also applies pressure to the inner surfaces of the traction and pressing wings extending inward from the covering body during the pulling process. This minimizes the gap between the inner surfaces of the traction and pressing wings and the edge of the affected tooth, allowing for a tight fit with the edge of the affected tooth after resin injection. This prevents the resin from forming a protrusion between the resin and the edge of the affected tooth, resulting in a smooth transition and saving on subsequent polishing work. At the same time, by opening a resin injection hole in the covering body, the problem of resin entering from the labial side of the molding piece can be avoided. In subsequent processing, only the resin corresponding to the injection hole needs to be removed and polished, thus effectively improving the restoration efficiency.

[0021] As a specific embodiment, the elastic molding sheet 1 is made of elastic silicone or elastic plastic, so that when the molding sheet is placed in the interdental space of adjacent teeth and pulled, it can fit better against the teeth.

[0022] For a specific embodiment, please refer to Figure 1 As shown, the top of the elastic molded sheet 1 has a protruding handle 4, which makes it easy to use tweezers to clamp the protruding handle 4 and quickly place the molded sheet in the interdental space of adjacent teeth to achieve wearing.

[0023] For a specific embodiment, please refer to Figure 1 As shown, the injection hole 21 is located in the upper part of the coating body 2, thereby allowing the flowable resin to be quickly injected into the inverted triangular gap between the teeth, thus filling the gap between the molded sheet and the teeth.

[0024] For a specific embodiment, please refer to Figure 1 As shown, the pulling and pressing wing 3 has multiple clamping holes 33 horizontally opened on it, so that the existing small clamping pins at the front end of the clamp can be inserted into the clamping holes 33 to pull and fix the entire molded piece, which is convenient and reliable.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
