Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis technology, specifically to a dental prosthesis fixing device based on magnetic adsorption. Background Technology

[0002] Magnetic dentures use the attraction of magnets to firmly attach the denture to a metal base plate inside the mouth. Compared to traditional removable dentures, magnetic dentures are designed to fit the shape of the mouth better, reducing pressure and discomfort on the soft tissues of the mouth, allowing patients to enjoy daily life more naturally. However, in traditional magnetic denture fixing devices, there may be some wobbling at the gaps on the mounting sides, which reduces the overall stability of the denture during use.

[0003] To overcome the above-mentioned defects, the existing technology (Chinese patent with announcement number CN213030890U, publication date 2021-04-23) provides a magnetic denture structure, including a fixator and a removable tooth. The upper end of the fixator has a removable tooth. Since the gingiva is prone to recession, the tooth root may shift along with it. The continuous fixed magnets on the upper end of the tooth root are replaced with individual fixed magnets, reducing the pain caused by the fixed magnets' inability to move due to root shift. The denture is continuously connected. For shifted tooth roots, the denture is inconvenient to install and use. The lower ends of the fixed teeth at both ends of the denture are connected together with a thread. The removable gingiva and removable tooth are installed according to the shift, causing the fixed magnets to shift without affecting the installation and use of other dentures. The lower end of the removable gingiva has a groove with a soft layer on the outside. The thread slides into the groove. The soft layer is elastic and easily returns to its original shape, limiting the removable gingiva to the thread, making it easy to install and remove, and easy to clean.

[0004] The aforementioned institutions use insertion wires to connect dentures, allowing for quick disassembly and installation of dentures and gums, which facilitates cleaning. However, in actual use, gaps may remain on the sides of the denture during installation, leading to a decrease in stability during subsequent use. Utility Model Content

[0005] The purpose of this invention is to provide a denture fixation device based on magnetic adsorption, so as to solve the problem mentioned in the background art that the denture fixation device may wobble at the gap on the installation side during use, resulting in a decrease in the overall stability of the denture during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a denture fixation device based on magnetic adsorption, comprising a base, a fixing rod installed inside the base, and a threaded rod engaged at the top of the fixing rod; a denture body threadedly connected to the outside of the threaded rod, and a fixing groove matching the threaded rod being formed at the top of the denture body; a push plate fixedly connected to the top of the threaded rod, a first magnetic block installed at the top of the threaded rod on the inner side of the push plate, and a sealing mechanism for reducing gaps and preventing shaking being provided at the top of the push plate; the sealing mechanism includes an elastic airbag, and the elastic airbag fits against the top of the denture body; a hollow rubber layer engaged at the outside of the first magnetic block, and the elastic airbag and the hollow rubber layer are connected by a flexible tube; a second magnetic block matching the first magnetic block is installed at the top of the denture body; and a positioning mechanism for connecting the fixing rod and the threaded rod is provided inside the threaded rod.

[0007] Furthermore, connecting springs are installed at both the front and rear ends of the top of the push plate, and the top of the connecting springs is connected to the top of the inside of the denture body.

[0008] Furthermore, the bottom end of the elastic airbag is attached to the top end of the push plate, and the push plate is slidably connected to the denture body.

[0009] Furthermore, the positioning mechanism includes a positioning rod, which is fixedly connected to the top of a fixed rod, and a longitudinal mating groove matching the positioning rod is provided at the middle position of the bottom end of the threaded rod.

[0010] Furthermore, the positioning rod passes through and extends into the interior of the longitudinal docking groove, and positioning rods are installed on both the left and right sides of the positioning rod. A transverse docking groove matching the docking block is opened at the top of the interior of the longitudinal docking groove.

[0011] Furthermore, the cross-section of the transverse docking groove is arc-shaped, and the transverse docking grooves are symmetrically distributed about the central axis of the vertical direction of the positioning rod.

[0012] Furthermore, magnets are installed on the sides of the docking block and the inner side of the transverse docking groove, and the positions of the magnets correspond to each other.

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

[0014] 1. By utilizing the interaction between the fixing rod and the base, the fixing rod can be fixedly connected to the inside of the denture body. The fixing rod can fix the position of the denture body and prevent the denture body from shifting during use.

[0015] Furthermore, the threaded rod and the fixed rod are aligned and fixed in position, thereby fixing the position of the threaded rod. Then, the denture body is rotated and threadedly connected to the threaded rod, thus installing the denture body. The denture body has a second magnetic block inside, and the threaded rod has a first magnetic block installed at the top. When the denture body is rotated and threadedly connected to the threaded rod, the threaded rod moves upward inside the denture body, causing the first and second magnetic blocks to attract and fix each other.

[0016] Furthermore, when the first magnetic block moves, it simultaneously drives the push plate to move as well. The push plate applies pressure to the elastic airbag as it moves, causing the gas inside the elastic airbag to be delivered to the interior of the hollow rubber layer through the hose. The hollow rubber layer can fill the gap between the first magnetic block and the interior of the denture body, reducing the shaking of the denture body during installation. It also avoids the problem of positional displacement between the first and second magnetic blocks after magnetic attraction.

[0017] 2. By adapting the docking block to the longitudinal docking groove, the docking block passes through the longitudinal docking groove and extends to the uppermost end of the threaded rod. Then, the fixing rod and the positioning rod are rotated, so that the docking block set at the top of the positioning rod synchronously drives the magnet block to rotate. The docking block and the transverse docking groove are also adapted to each other, so that the docking block can slide inside the transverse docking groove after rotation, thereby making the docking block and the magnet block mutually attracted and fixed.

[0018] Furthermore, after the push plate is pushed upward by the threaded rod, the push plate automatically resets through the elastic force of the connecting spring, causing the push plate to stop squeezing the elastic airbag. This allows the elastic airbag to automatically reset and extract the gas inside the hollow rubber layer and transport it back into the elastic airbag, thereby restoring the interior of the hollow rubber layer to its initial state and reducing the amount of gas inside the hollow rubber layer.

[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 , Figure 3 and Figure 6 The technical solution shown addresses the problem that the gaps on the installation side of the denture fixation device may wobble during use, leading to a decrease in the overall stability of the denture. This magnetically adsorbed denture fixation device discloses a positioning mechanism, including a base 1. A fixing rod 3 is installed inside the base 1, and a threaded rod 4 is engaged at the top of the fixing rod 3. The threaded rod 4 is externally threaded to the denture body 2, and a fixing groove 5 matching the threaded rod 4 is provided at the top of the denture body 2. A push plate 11 is fixedly connected to the top of the threaded rod 4, and a first magnetic block 6 is installed at the top of the threaded rod 4 inside the push plate 11.

[0028] In this example, the fixing rod 3 is installed inside the base 1. The fixing rod 3 and the base 1 cooperate with each other to fix the fixing rod 3 inside the denture body 2. The fixing rod 3 can fix the position of the denture body 2 and prevent the denture body 2 from shifting during use. Then, the threaded rod 4 is aligned and fixed with the fixing rod 3 to fix the position of the threaded rod 4. Then, the denture body 2 is rotated and threadedly connected to the threaded rod 4 to install the denture body 2. The denture body 2 is provided with a second magnetic block 7 inside, and a first magnetic block 6 is installed at the top of the threaded rod 4. When the denture body 2 is rotated and threadedly connected to the threaded rod 4, the threaded rod 4 moves upward inside the denture body 2, so that the first magnetic block 6 and the second magnetic block 7 attract and fix each other.

[0029] Example 2: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The technical solution shown addresses the potential issue of magnetic misalignment during installation of the denture body 2. This magnetically-based denture fixing device discloses a sealing mechanism. The top of the push plate 11 is equipped with a sealing mechanism to reduce gaps and prevent wobbling. The sealing mechanism includes an elastic airbag 9, which fits against the top of the denture body 2. A hollow rubber layer 8 is engaged with the outer side of the first magnetic block 6, and the elastic airbag 9 and the hollow rubber layer 8 are connected by a flexible tube. A second magnetic block 7, matching the first magnetic block 6, is installed at the top of the denture body 2. Connecting springs 10 are installed at both the front and rear ends of the top of the push plate 11, and the tops of the connecting springs 10 are connected to the top of the denture body 2. The bottom of the elastic airbag 9 fits against the top of the push plate 11, and the push plate 11 and the denture body 2 are slidably connected.

[0030] In this example, when the first magnetic block 6 moves, it synchronously drives the push plate 11 to move as well. When the push plate 11 moves, it applies pressure to the elastic airbag 9, thereby causing the gas inside the elastic airbag 9 to be transported to the interior of the hollow rubber layer 8 through the hose. The hollow rubber layer 8 can fill the gap between the first magnetic block 6 and the interior of the denture body 2, reducing the shaking of the denture body 2 during installation. It also avoids the problem of positional misalignment between the first magnetic block 6 and the second magnetic block 7 after magnetic attraction. After the push plate 11 is pushed upward by the threaded rod 4, the push plate 11 automatically resets through the elastic force of the connecting spring 10, so that the push plate 11 stops squeezing the elastic airbag 9. This allows the elastic airbag 9 to automatically reset and extract the gas inside the hollow rubber layer 8 and transport it back to the interior of the elastic airbag 9, thereby restoring the interior of the hollow rubber layer 8 to its initial state and reducing the amount of gas inside the hollow rubber layer 8.

[0031] Example 3: Figure 1 , Figure 2 , Figure 3 and Figure 4The technical solution shown addresses the problem of the denture body 2 being difficult to disassemble and clean quickly: This magnetically adsorbed denture fixation device discloses a positioning mechanism. The threaded rod 4 has an internal positioning mechanism for connecting the fixing rod 3 and the threaded rod 4. The positioning mechanism includes a positioning rod 12, which is fixedly connected to the top of the fixing rod 3. A longitudinal mating groove 15 matching the positioning rod 12 is formed at the middle of the bottom end of the threaded rod 4. The positioning rod 12 passes through and extends into the interior of the longitudinal mating groove 15, and positioning rods 12 are installed on both the left and right sides of the positioning rod 12. A transverse mating groove 16 matching the mating block 13 is formed at the top of the interior of the longitudinal mating groove 15. The transverse mating groove 16 has an arc-shaped cross-section and is symmetrically distributed about the vertical central axis of the positioning rod 12. Magnet blocks 14 are installed on the sides of the mating block 13 and the inner sides of the transverse mating groove 16, and the positions of the magnet blocks 14 correspond to each other.

[0032] In this example, the positioning rod 12 is inserted into the lower end of the threaded rod 4. The mating block 13 and the longitudinal mating groove 15 are mutually adapted. The mating block 13 passes through the longitudinal mating groove 15 and extends to the uppermost end of the threaded rod 4. Then, the fixing rod 3 and the positioning rod 12 are rotated, so that the mating block 13 set at the top of the positioning rod 12 synchronously drives the magnet block 14 to rotate. The mating block 13 and the transverse mating groove 16 are also mutually adapted, so that the mating block 13 can slide inside the transverse mating groove 16 after rotation, thereby attracting and fixing the mating block 13 and the magnet block 14 to each other. The direction of rotation of the positioning rod 12 is opposite to the rotation direction of the threaded connection of the denture body 2. Therefore, when the denture body 2 is connected and fixed by the threaded connection, the threaded rod 4 will not become loose due to the disassembly of the denture. When the thread groove on the outside of the threaded rod 4 is worn, the threaded rod 4 and the denture body 2 can be replaced separately, thereby effectively reducing the cumbersome operation when replacing the denture.

[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.
