Description

Technical Field

[0001] This utility model relates to the field of dental caries filling technology, specifically a molded sheet for filling proximal caries. Background Technology

[0002] During the filling process, the molded piece is a crucial protective component. It seals the cavity caused by the decay, protecting the tooth from further damage. It also isolates the filling material from the influence of saliva, blood, and other liquids, ensuring that the filling material can fully harden and achieve the best restorative effect.

[0003] The existing method of tooth filling involves placing a molded piece on the adjacent surface of the affected tooth, and then filling the space between the molded piece and the tooth with filling material to complete the filling. However, due to the different shapes of teeth, it is impossible to guarantee that the molded piece can fit tightly with the adjacent teeth, which can lead to leakage of filling material, forming overhangs and gaps, affecting the filling effect and having limitations.

[0004] The reason for this problem is that the main function of the molded piece is to fit tightly against the adjacent teeth to form a closed space so that the filling material can accurately fill the defect. Due to the differences in tooth shape and the limitations of the interproximal space, it is not possible to guarantee that the tooth can fit tightly against the molded piece, which will cause the filling material to overflow, affecting the aesthetics, and will also irritate the gums, causing inflammation or discomfort. Furthermore, due to the poor protective effect, the filling material may not cure completely or the curing quality may be reduced, which has limitations. Therefore, we propose a molded piece for interproximal caries filling to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a molded sheet for filling proximal caries, which solves the problem that due to the different shapes of teeth and the limited space on the proximal surfaces, it is impossible to ensure that the molded sheet can fit tightly with adjacent teeth, which can lead to leakage of filling material, the formation of overhangs and gaps, and affect the filling effect, thus having limitations.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a molding sheet for filling proximal caries, comprising a proximal filling unit disposed on one side of the tooth, wherein the proximal filling unit comprises a molding sheet, an injection hole, and a retaining strip;

[0007] The injection hole is located inside the molded piece. High-flow resin is injected into the tooth through the injection hole to fill it. The retaining strip is located on one side of the molded piece. The retaining strip and the tooth clamp the molded piece in the middle. The retaining strip is used to clamp and fix the molded piece after it is installed.

[0008] Preferably, the molding piece is arc-shaped, and one side of the molding piece fits into the tooth.

[0009] Preferably, the retaining strip is arc-shaped, and the arc-shaped surface of the retaining strip fits tightly against the injection hole inside the molded sheet. The retaining strip is used to prevent the overflow of highly flowing resin.

[0010] Preferably, a cheek-side clamping member is provided on one side of the molded sheet, and the cheek-side clamping member includes a clamping strip and fixing teeth;

[0011] The fixing teeth are located on one side of the clamping bar and are arranged symmetrically along the central axis.

[0012] Preferably, the clamping strip is U-shaped, and the inner wall of the clamping strip fits tightly against the injection hole to prevent the filler from overflowing and forming protrusions and gaps.

[0013] Preferably, the fixing teeth are continuous sawtooth-shaped, and the fixing teeth fit tightly with the teeth. The fixing teeth are used to fix the position of the clamping strip and prevent the clamping strip from moving during the curing process of the filler.

[0014] This utility model discloses a molded piece for filling proximal caries, which has the following beneficial effects:

[0015] This device reduces the need for adjacent space during material filling by creating injection holes in the molding sheet, making it easier to fill teeth.

Clamping strip 13 is set on one side of the molded piece 11. Clamping strip 13 and tooth clamp the molded piece 11 in the middle. Clamping strip 13 is used to clamp and fix the molded piece 11 after installation.

[0027] The molding sheet 11 is arc-shaped, and one side of the molding sheet 11 fits against the teeth. The retaining strip 13 is arc-shaped as a whole, and the arc-shaped surface of the retaining strip 13 fits tightly against the injection hole 12 inside the molding sheet 11. The retaining strip 13 is used to prevent the overflow of high-flow resin.

[0028] In this embodiment, when using the device, the molding sheet 11 is placed between the normal tooth and the carious tooth, and high-flow resin is injected into the interior of the carious tooth through the injection hole 12. After injection, the retaining strip 13 is placed between the normal tooth and the molding sheet 11, so that the retaining strip 13 holds the molding sheet 11 in place, making it fit tightly against the carious tooth. The end of the retaining strip 13 abuts against the injection hole 12, so that the high-flow resin cannot flow out through the injection hole 12 and gaps, avoiding overhangs that would affect the normal filling of the material. The existing retaining strip 13 is arc-shaped, which can fit the tooth better and meet the user's needs. Example
