Description

Technical Field

[0001] This utility model relates to the field of dental pulp restoration technology, and in particular to a novel bean-shaped sheet. Background Technology

[0002] The incidence of caries on the proximal surfaces of posterior teeth is relatively high, often due to food impaction that is not removed in time, leading to tooth decay under the influence of bacteria, microorganisms, and other factors. Clinically, cavities affecting the proximal surfaces of posterior teeth after thorough removal of decayed material are called Class II posterior cavities. Restoration of this type of cavity requires the use of a preformed piece separated from the adjacent tooth. The preformed piece fits tightly against the decayed tooth, and resin filling is applied. This method effectively restores the morphology of the proximal contact area and prevents food impaction.

[0003] In related technologies, the combination of soybean-shaped sheets and soybean clips can effectively wedge open the gaps between adjacent parts, and after filling, they can achieve a close contact relationship. Therefore, it is widely used in clinical practice.

[0004] However, traditional bean-shaped cutting sheets have some drawbacks. They are mainly small and easily fall into the mouth if not held tightly during operation, which may lead to accidental swallowing and life-threatening situations. When the interdental spaces are tight, the bean-shaped cutting sheets are difficult to remove, and the operation may inevitably compress the gums, causing bleeding. Sometimes, it is even necessary to use a needle holder, which reduces work efficiency, increases consumables, and causes fear for patients. For beginners, the upper and lower edges of the bean may be reversed, resulting in poor recovery of the contact area and marginal ridge. Utility Model Content

[0005] To solve the above problems, this utility model provides a novel type of fermented soybean slice, the technical solution of which is as follows: A novel bean-shaped filling sheet for posterior Class II cavity filling and restoration includes: The main body of the molded sheet has a top end and a bottom end, the bottom end having an arc-shaped structure; Multiple protrusions are located on the top end and connected to the molded sheet body; During use, the main body of the molded piece is located between two adjacent teeth, and in the height direction of the teeth, the height dimension of the main body of the molded piece is greater than the height dimension of the teeth.

[0006] In some embodiments, the protrusion has a ring structure and is integral with the main body of the molded sheet.

[0007] In some embodiments, the outer diameter of the annular structure is 3 mm and the inner diameter is 1 mm; The hole in the annular structure is used to insert dental floss.

[0008] In some embodiments, the top end has two protrusions and a recess, the recess being located between the two protrusions, and each protrusion being located above the protrusion.

[0009] In some embodiments, the molded sheet body has a double-layer composite structure, wherein the outer layer is a flexible elastic layer and the inner layer is a support layer.

[0010] In some embodiments, the outer layer has a smooth layer at its surface edge.

[0011] In some embodiments, the surface edges of the outer layer and the edges of the protrusions have a rough structure.

[0012] The technological advancements achieved by this invention compared to existing technologies are as follows: The main body of the molded piece in this utility model has a top and a bottom, which can be clearly distinguished from the top and bottom, and can be accurately placed during use. The top is also provided with multiple protrusions, which allow doctors to easily pick up or place the new bean-shaped molded piece by holding the protrusions, avoiding pressure on the gums and causing bleeding, thus ensuring safety and reliability.

[0016] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0017] like Figures 1 to 9 As shown, this utility model discloses a novel bean-shaped molding sheet for filling and restoring Class II cavities in posterior teeth. It includes a molding sheet body 1 and a protruding portion 2. The molding sheet body 1 has a top end 10 and a bottom end 11, the structures of which can be different. In one example, such as... Figures 1 to 3 As shown, the bottom end 11 has an arc-shaped structure, which can fit against the gingival area 4, ensuring that the new bean-shaped molding piece can be placed stably and comfortably. Multiple protrusions 2 are located on the top end 10. On the one hand, the protrusions 2 can help beginners quickly identify and determine the direction, thereby ensuring the correct placement position. On the other hand, the protrusions 2 make it easy for doctors to pick up or place the piece, thereby avoiding pressure on the gingival 4 and causing bleeding. The protrusions 2 are connected to the molding piece body 1, and the connection method can be adapted to the needs.

[0018] During use, such as Figure 1 , Figures 7 to 9 As shown, the dentist can use tweezers or other equipment to pick up the main body 1 of the molding piece and place it between two adjacent teeth 3. Because the new type of bean-shaped molding piece can deform, it can better fit the teeth 3. That is, the two sides of the new bean-shaped molding piece are bent and moved towards the side of the tooth 3 that needs repair, and a suitable wedge is placed. The bean-shaped clamp is then fixed with bean-shaped forceps to allow for subsequent operations. In the height direction of the tooth 3, such as... Figure 3 As shown, the height of the main body 1 of the molded sheet is greater than that of the tooth 3. This makes it easier for the dentist to fill the caries in the patient's tooth 3, and also prevents the filling material from scattering to other places, thereby improving the restoration effect. It should be noted that the tooth 3 includes the crown 31 and the root 32. The gingiva 4 covers the root 32. In the new type of bean-shaped molded sheet, the top 10 of the main body 1 of the molded sheet with the protrusion 2 faces upward, and the bottom 11 contacts the gingiva 4, so that the height of the main body 1 of the molded sheet is greater than that of the root 32 in the tooth 3, thereby ensuring the quality of subsequent filling.

[0019] In some embodiments, the shape of the protrusion 2 can be adapted as needed, such as... Figure 1 and Figure 3As shown, the protrusion 2 has a circular ring structure. The smooth edge of the protrusion 2 ensures safety. During use, the protrusion 2 and the main body 1 of the forming sheet are integrated. The new type of bean curd forming sheet with an integrated structure is sturdy and durable. In actual operation, doctors do not need to worry about the connection between the parts being loose or falling off, reducing the possibility of accidents during operation.

[0020] In some embodiments, the size of the protrusion 2 can be adaptively set as needed. In one example, the outer diameter of the annular protrusion 2 is 3 mm and the inner diameter is 1 mm to ensure operational flexibility. Figure 1 , Figure 3 and Figure 4 As shown, the hole in the protrusion 2 of the circular structure is used to insert dental floss. After the dental floss passes through the hole, it is knotted, and the end of the dental floss is tied and looped on the doctor's finger. This can effectively prevent the new type of bean-shaped molding sheet from falling off and ensure the quality of the restoration.

[0021] In some embodiments, such as Figures 1 to 4 As shown, the structure of the top 10 is different from that of the bottom 11 of the arc-shaped structure, so that the position can be clearly identified. The top 10 has two protrusions 101 and a recess 102. The recess 102 is located between the two protrusions 101, thus forming a wave shape, which is different from the bottom 11 of the arc-shaped structure. This avoids the position being reversed and causing poor restoration of the tooth shape. In one example, the number of protrusions 2 is the same as the number of protrusions 101, so that each protrusion 2 is located above the corresponding protrusion 101. When the doctor places it, it will be placed with the two protrusions 101 and the recess 102 facing upwards. During operation, it can effectively wrap the tooth 3 to be restored. That is, the recess 102 is located between two adjacent teeth 3, and each protrusion 101 is located on the side of the tooth 3 to be restored, which facilitates subsequent filling and restoration.

[0022] In some embodiments, such as Figure 1 and Figure 5 As shown, the main body 1 of the molding piece has a double-layer composite structure, including an inner layer 6 and an outer layer 5. The outer layer 5 is a flexible elastic layer, which can be made of medical silicone or thermoplastic polyurethane rubber. It can deform according to the external shape of the tooth 3, better conforming to the complex structure of the tooth 3 in the oral cavity, thereby ensuring a close fit between the new bean-shaped molding piece and the tooth 3. At the same time, the flexible elastic layer can improve the patient's comfort when wearing it, reduce material stress, and improve the accuracy of operation. The inner layer 6 is a support layer, which provides structural strength and stability for the main body 1 of the molding piece. The support layer can be made of polyimide or stainless steel, etc., which effectively supports the bean-shaped molding piece, so that it maintains the stability of its shape during operation and is not easily deformed or displaced, thereby efficiently completing the subsequent restoration work.

[0023] In some embodiments, continue to refer to Figure 1 and Figure 5 The outer layer 5 has a smooth layer 7 at its surface edge to prevent damage to soft tissue during use. In some embodiments, the novel soybean-shaped sheet may have a rough structure 8, such as in one example, as shown below. Figure 5 and Figure 6 As shown, the outer layer 5 has a roughened surface edge structure 8, which increases friction and allows for a tighter connection between the bean-shaped clip and the new bean-shaped molding piece. This ensures the new bean-shaped molding piece is more stable during the repair process, reducing potential slippage or displacement. This helps doctors to place materials and sculpt shapes more precisely, ensuring a lasting repair effect. In another example, as... Figure 9 As shown, the edge of the protrusion 2 has a rough texture 8 (not shown in the attached figure), which allows the doctor to firmly grasp the protrusion 2 with tweezers or hook it with a pointed probe, ensuring stability during removal or placement. The rough texture 8 on the surface edge of the outer layer 5 and the edge of the protrusion 2 effectively ensures the stability of the doctor's operation.

[0024] The working principle of the novel fermented soybean slice of this application is as follows: like Figures 1 to 9 As shown, first, the dentist inserts dental floss into the central hole of the protrusion 2 on the new type of bean-shaped molded piece. The end of the dental floss is tied and looped around the dentist's finger to ensure that the new type of bean-shaped molded piece does not fall off easily. The top 10 with the protrusion 2 is facing upwards. Then, the dentist uses tweezers to clamp the main body 1 or the protrusion 2 of the molded piece and places it in the gap between two teeth 3 so that the bottom 11 contacts the gum 4.

[0025] Next, place a suitable wedge and fix the bean clamp with bean clamp pliers. Check that the bean clamp is not pressing on the gum 4. Ensure that the new bean molding piece is tightly attached to and wraps around the patient's tooth 3. Gently shake it. If it does not loosen, it means that the installation is successful, thereby filling the caries in the patient's tooth 3.

[0026] Finally, after the filling is completed, remove the wedge and the bean-shaped clip, hook the protrusion 2 with a circular structure on the top 10 with a pointed probe, and pull it from the left and right towards the occlusal side until it is completely removed, thus completing the restoration operation.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
