Description

Technical Field

[0001] This utility model relates to the field of denture technology, specifically to a denture structure with adjustable biting force. Background Technology

[0002] Dentures, also known as false teeth, are artificial devices that replace missing teeth. They are designed to restore the shape, function, and aesthetics of teeth and provide support for the face and neuromuscular system of people with missing teeth. However, traditional dentures cannot provide occlusal cushioning during biting, which leads to wear and tear and a shortened lifespan.

[0003] To overcome the aforementioned shortcomings, existing technology (Chinese patent publication number CN113952056B, publication date 2023-05-02) proposes a complete denture with controllable occlusal force. Addressing the issue that existing complete dentures cannot provide assisted occlusion, thus hindering daily use, the following solution is proposed: It includes an upper dental tray with a lower dental tray at its bottom. The upper and lower dental trays have identical structures. A base plate is fixedly connected to the bottom of the upper dental tray, and multiple denture bodies are mounted on the bottom of the base plate. A first spring between a first and second horizontal plate provides the first horizontal plate with adjustable vertical elasticity. A control block controls the rotation of a first threaded screw within a first groove, thereby controlling the distance between a first and second slider. This adjustment of the distance between the first and second horizontal plates changes the compression of the first spring, thus altering its elastic force. Ultimately, this achieves the goal of adjusting and controlling the occlusal force of the denture using a spring.

[0004] The aforementioned mechanism controls the biting force by utilizing the cooperation between the spring and the cross plate. However, in actual use, the presence of springs at both the top and bottom leads to a greater force required to ensure the dentures close properly during biting. This results in a decrease in the speed and efficiency of food cutting and grinding during chewing, affecting the user's normal eating. Utility Model Content

[0005] The purpose of this invention is to provide a denture structure with adjustable biting force to solve the problem mentioned in the background art that traditional dentures cannot provide biting cushioning during use, resulting in easy wear and shortened service life.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable occlusal denture structure, comprising an arc-shaped limiting member, with mounting limiting members installed on both sides of the arc-shaped limiting member, and a protective silicone block installed on the side of the mounting limiting member. The top of the protective silicone block is threadedly connected to the denture body. An adjustment mechanism for adjusting the occlusal degree is installed at the bottom of the denture body. The adjustment mechanism includes a mounting block, which is fixedly connected to the bottom of the denture body. The top of the protective silicone block has a threaded groove that matches the mounting block. A shielding mechanism for reducing gaps and increasing fit is installed at the top inside the protective silicone block.

[0007] Furthermore, a shape memory alloy sheet is installed inside the protective silicone block, and the length of the shape memory alloy sheet is equal to the length of the protective silicone block.

[0008] Furthermore, the shielding mechanism includes a fixing plate, which is positioned above the interior of the protective silicone block. A connecting spring is installed inside the fixing plate, and a movable rod is installed at the top of the connecting spring. A push plate is installed at the top of the movable rod.

[0009] Furthermore, the top end of the push plate is attached to the bottom end of the mounting block, and the diameter of the push plate is larger than the diameter of the bottom end of the mounting block.

[0010] Furthermore, a shielding block is installed at the bottom of the fixing plate, and the shielding block is located at the top inside the protective silicone block.

[0011] Furthermore, a positioning block is installed on the top of the protective silicone block, and a positioning groove matching the positioning block is opened on the top of the shielding block.

[0012] Furthermore, the top of the blocking block is provided with a fixing groove, and the bottom end of the connecting spring extends into the interior of the fixing groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By fitting the arc-shaped limiting piece to the inside of the original gum, and then placing the installation limiting piece on the outside of the intact tooth to perform basic positioning of the denture mechanism itself, the mounting block at the bottom of the denture body and the threaded groove at the top of the protective silicone block are threaded together to complete the installation and fixation of the denture body.

[0015] Furthermore, the protective silicone block itself has a certain degree of elasticity, so the installation depth of the denture body can be adjusted according to the actual occlusal surface of the teeth and the occlusal force, thereby reducing the wear of the denture body during subsequent use. When the occlusion between the denture body and the teeth is obvious, the surface of the denture body can be slightly polished by the mechanical polishing component to reduce the occlusal protrusion, thereby ensuring the comfort of the denture body during use.

[0016] Furthermore, the protective silicone block has a certain degree of elasticity, which allows the edges of the protective silicone block to remain in close contact with the denture body when the installation position of the denture body is adjusted, thereby ensuring the stability of the denture body installation.

[0017] 2. The protective silicone block is fitted to the user's gums through the inner side. The shape of the memory alloy sheet is adjusted according to the user's actual gum condition, so that the protective silicone block can maintain a comfortable fit when it is fitted to the gums. Even if the user places the denture body in a place with different temperatures, the memory alloy sheet can return to its initial state after returning to normal temperature, maintaining the fit between the denture body and the gums, and increasing the comfort of the denture body when biting.

[0018] Furthermore, the connecting spring and movable rod inside the fixed plate can push the push plate upward, so that the top of the push plate can be in contact with the bottom of the denture body. This allows the gap between the denture body and the protective silicone block to be basically blocked. The blocking block is attached to the bottom of the fixed plate. By using the alignment between the positioning block and the positioning groove, the position of the blocking block is fixed, thereby blocking the gap between the inner side of the protective silicone block and the gum, reducing the entry of food debris.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: As Figure 1 , Figure 2 and Figure 3 The technical solution shown addresses the problem of dentures being difficult to adjust during use, leading to easy wear: the adjustable bite denture structure discloses an adjustment mechanism, including an arc-shaped limiting member 1. Both sides of the arc-shaped limiting member 1 are equipped with mounting limiting members 2, and protective silicone blocks 4 are mounted on the sides of the mounting limiting members 2. The top of the protective silicone blocks 4 is threadedly connected to the denture body 3. An adjustment mechanism for adjusting the bite is installed at the bottom of the denture body 3. The adjustment mechanism includes a mounting block 6, which is fixedly connected to the bottom of the denture body 3. The top of the protective silicone block 4 has a threaded groove 7 that matches the mounting block 6.

[0028] In this example, when installing the denture body 3, the arc-shaped limiting member 1 needs to be fitted to the inside of the original gum line. Then, the installation limiting member 2 is fitted onto the outside of the intact tooth to provide basic positioning for the denture mechanism. Next, the mounting block 6 at the bottom of the denture body 3 is threaded into the threaded groove 7 at the top of the protective silicone block 4, completing the installation and fixation of the denture body 3. During use, the protective silicone block 4 has a certain degree of elasticity, so the installation depth of the denture body 3 can be adjusted according to the actual occlusal surface and occlusal force of the teeth. Adjustments are made to reduce wear on the denture body 3 during subsequent use. When the bite between the denture body 3 and the teeth is significant, the surface of the denture body 3 can be lightly polished by a mechanical polishing component to reduce the protruding part of the bite, thereby ensuring the comfort of the denture body 3 during use. Furthermore, because the protective silicone block 4 has a certain degree of elasticity, when the installation position of the denture body 3 is adjusted, the side of the protective silicone block 4 can also maintain a close fit with the denture body 3, thereby ensuring the stability of the installation of the denture body 3.

[0029] Example 2: Figure 1 , Figure 2 and Figure 3 The technical solution shown addresses the problem that the protective silicone block 4 does not fit tightly enough against the user's gums during use: the adjustable bite force denture structure discloses a memory alloy sheet 5, which is installed inside the protective silicone block 4, and the length of the memory alloy sheet 5 is equal to the length of the protective silicone block 4.

[0030] In this example, the inner side of the protective silicone block 4 is fitted to the user's own gums. By adjusting the shape of the memory alloy sheet 5 according to the user's actual gum condition, the protective silicone block 4 can maintain comfort when it is fitted to the gums. Even when the user places the denture body 3 in a place with different temperatures, the memory alloy sheet 5 can return to its initial state after returning to normal temperature, maintaining the fit between the denture body 3 and the gums, thus increasing the comfort of the denture body 3 when biting.

[0031] Example 3: Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6The technical solution shown addresses the problem of gaps remaining between the denture body 3 and the protective silicone block 4 at the installation point. This adjustable bite denture structure discloses a shielding mechanism. A shielding mechanism for reducing gaps and increasing fit is installed at the top of the interior of the protective silicone block 4. The shielding mechanism includes a fixing plate 11, which is positioned above the interior of the protective silicone block 4. A connecting spring 10 is installed inside the fixing plate 11, and a movable rod 9 is installed at the top of the connecting spring 10. The top of the movable rod 9 is... A push plate 8 is installed; the top end of the push plate 8 is attached to the bottom end of the mounting block 6, and the diameter of the push plate 8 is larger than the diameter of the bottom end of the mounting block 6; a blocking block 13 is installed at the bottom end of the fixing plate 11, and the blocking block 13 is located at the top end inside the protective silicone block 4; a positioning block 14 is installed at the top end of the protective silicone block 4, and a positioning groove 15 matching the positioning block 14 is opened at the top end of the blocking block 13; a fixing groove 12 is opened at the top end of the blocking block 13, and the bottom end of the connecting spring 10 extends into the interior of the fixing groove 12.

[0032] In this example, there may be a gap between the denture body 3 and the bottom of the protective silicone block 4. The connecting spring 10 and the movable rod 9 inside the fixing plate 11 can push the push plate 8 upward, so that the top of the push plate 8 can be in contact with the bottom of the denture body 3. This allows the gap between the denture body 3 and the protective silicone block 4 to be basically covered. The blocking block 13 is attached to the bottom of the fixing plate 11. The position of the blocking block 13 is fixed by the alignment between the positioning block 14 and the positioning groove 15. This covers the gap between the inner side of the protective silicone block 4 and the gum, reducing the entry of food debris.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
