Description

Technical Field

[0001] The present application relates to the technical field of dentures, and in particular to anti-loosening dentures. Background Art

[0002] Dentures are artificial teeth that are usually used to replace missing natural teeth or strengthen damaged teeth. Dentures can be divided into two types: full dentures and partial dentures. Common ones include porcelain veneer dentures, snap-on dentures, porcelain teeth, all-ceramic teeth, etc.

[0003] An anti-loosening denture mentioned in an existing Chinese public patent (authorization announcement number: CN220001968U) can be connected to a base through a connecting part, the base is fixed on the gums, the denture body is installed on the connecting part, and connected to the base through the connecting part, and stably installed on the gums, the denture body is fixed by a tapered thread structure, and is adsorbed and fixed by a magnetic groove and a magnetic block to lock the denture body, maintain the stability of the denture, and prevent the denture body from falling off.

[0004] When currently used, dentures are mostly fixed to the top of the base by threads. However, long-term use of dentures for chewing will cause friction and pressure between the denture and food. Long-term use may cause the threads between the denture and the base to loosen, making the denture unstable and causing discomfort. Utility Model Content

[0005] The purpose of the present application is to provide an anti-loosening denture to solve the problem that the chewing movement between the denture and the food will generate friction and pressure, which may cause the threads between the denture and the base to loosen.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] An anti-loosening denture comprises a denture body, a base is arranged at the bottom of the denture body, a connecting block is arranged between the denture body and the base, the top of the connecting block is fixedly connected to the denture body, the base is arranged in a cone shape, the outer surface of the base is arranged with an external thread, a placement groove is arranged inside the base, the placement groove and the connecting block are slidably arranged, a fixing groove is arranged inside the placement groove, the fixing groove is arranged inside with an internal thread, a threaded rod is fixedly connected to the bottom of the connecting block, the threaded rod is threadedly connected to the fixing groove, and a reinforcement mechanism is arranged inside the connecting block.

[0008] By adopting the above technical solution, the base is rotated and installed inside the gums, and then the threaded rod is placed in the fixing groove, and then the connecting block is rotated so that the connecting block is fixed inside the placement groove. Finally, the denture body is fixed to the connecting block by adhesive on the top of the connecting block, thereby completing the installation of the denture body. The connection strength between the connecting block and the base can be enhanced by the reinforcement mechanism.

[0009] Furthermore, the reinforcement mechanism includes a cavity opened inside the connecting block, the inner bottom wall of the cavity is equidistantly fixedly connected to a plurality of vertical plates, a telescopic rod is fixedly connected to one side of the vertical plate, a spring is sleeved on the outer surface of the telescopic rod, an end of the telescopic rod away from the vertical plate is fixedly connected to a resistance block, a plurality of movable holes are equidistantly opened on the outer surface of the connecting block, the resistance block is slidably connected to the movable holes, and a plurality of resistance grooves are equidistantly fixedly connected to the inner wall of the placement groove, and the resistance grooves are snap-connected to the resistance block.

[0010] By adopting the above technical solution, when the connecting block is connected to the base, the inner wall of the placement groove will contact the interference block, so that the telescopic rod and the spring will deform and shrink after being subjected to force, generating elastic potential energy. When the interference block moves to the position of the interference groove, the elastic potential energy of the spring is released, thereby driving the interference block to enter the interior of the interference groove, thereby completing the snap connection, achieving the purpose of enhancing the mechanical locking between the connecting block and the base, reducing the risk of loosening of the thread of the connecting block due to stress such as chewing, thereby improving the stability and durability of the connecting block.

[0011] Furthermore, the end of the resistance block away from the telescopic rod is set to be conical, and the resistance block is slidably arranged inside the placement groove.

[0012] By adopting the above technical solution, the resistance block is set to be conical, and under the action of the inclined surface of the resistance block, the resistance block is forced to move.

[0013] Furthermore, one end of the resistance block away from the telescopic rod is rotatably connected with a plurality of balls at equal distances.

[0014] By adopting the above technical solution, the balls make it easier for the abutment block to slide against the inner wall of the placement groove.

[0015] Furthermore, sliders are fixedly connected to both sides of the abutment block, and sliding grooves are provided on both sides of the inner wall of the movable hole. The sliders match the shapes of the sliding grooves, and the sliders are slidably connected to the sliding grooves.

[0016] By adopting the above technical solution, the sliding block and the sliding groove provide a guiding function for the interference block.

[0017] Furthermore, a side of the vertical plate away from the telescopic rod is fixedly connected with an oblique brace, and one end of the oblique brace away from the vertical plate is fixedly connected to the inner bottom wall of the cavity.

[0018] By adopting the above technical solution, the diagonal brace can enhance the stability of the connection and effectively transmit force.

[0019] Furthermore, a fixing pad is fixedly connected to the inner bottom wall of the placement groove, and a plurality of protrusions are fixedly connected to the top of the fixing pad at equal intervals.

[0020] By adopting the above technical solution, the protrusions can increase the friction between the base and the connecting block.

[0021] Furthermore, positioning blocks are fixedly connected to both sides of the bottom of the connecting block, positioning grooves are provided on both sides of the top of the base, the positioning blocks are adapted to the shapes of the positioning grooves, and the positioning grooves and the positioning blocks are slidably arranged.

[0022] By adopting the above technical solution, accurate positioning of the denture can be achieved through the sliding arrangement of the positioning block and the positioning groove.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. In the present application, when the connecting block is connected to the base, the resistance block will move inside the movable hole after being subjected to pressure. When the resistance block moves to the position of the resistance groove, the spring drives the resistance block to enter the inside of the resistance groove, thereby completing the engagement, thereby achieving the purpose of enhancing the mechanical locking between the connecting block and the base, reducing the risk of loosening of the thread of the connecting block due to stress such as chewing, thereby improving the stability of the connecting block body.

[0025] 2. In the present application, when the spring retracts under force, a stable triangular structure is formed by the connecting block, the vertical plate and the diagonal brace, which can enhance the stability of the connection and effectively transmit force, thereby ensuring the normal use of the resistance block. When the connecting block is fixed to the base, the friction between the base and the connecting block can be increased by the convex points on the fixing pad, thereby further improving the connection strength between the base and the connecting block.

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiments of the present application disclose an anti-loosening denture.

[0034] Reference Figure 1 , Figure 2 and Figure 3 , an anti-loosening denture comprises a denture body 1, a base 2 is arranged at the bottom of the denture body 1, a connecting block 3 is arranged between the denture body 1 and the base 2, the top of the connecting block 3 is fixedly connected to the denture body 1, the base 2 is arranged in a cone shape, the outer surface of the base 2 is arranged with an external thread, a placement groove is arranged inside the base 2, the placement groove and the connecting block 3 are slidably arranged, a fixing groove 4 is arranged inside the placement groove, the fixing groove 4 is arranged inside with an internal thread, a threaded rod 5 is fixedly connected to the bottom of the connecting block 3, the threaded rod 5 is threadedly connected to the fixing groove 4, and a reinforcement mechanism is arranged inside the connecting block 3.

[0035] When installing the denture body 1, first, the doctor will pre-drill a hole on the gums, then rotate the base 2 to install it inside the gums, then place the threaded rod 5 in the fixing groove 4, and then rotate the connecting block 3, which is threadedly connected to the fixing groove 4 through the threaded rod 5, so that the connecting block 3 is fixed inside the placement groove, and finally the denture body 1 is fixed to the connecting block 3 on the top of the connecting block 3 by an adhesive, thereby completing the installation of the denture body 1. When the connecting block 3 is connected to the base 2, the connection strength between the connecting block 3 and the base 2 can be enhanced by the reinforcement mechanism, thereby reducing the risk of thread loosening.

[0036] Reference Figure 2 , Figure 3 and Figure 4 The reinforcement mechanism includes a cavity opened inside the connecting block 3, and the inner bottom wall of the cavity is fixedly connected to a plurality of vertical plates 6 at equal intervals. A telescopic rod 7 is fixedly connected to one side of the vertical plate 6. A spring 8 is sleeved on the outer surface of the telescopic rod 7. An end of the telescopic rod 7 away from the vertical plate 6 is fixedly connected to a resistance block 10. A plurality of movable holes 9 are opened at equal intervals on the outer surface of the connecting block 3. The resistance block 10 is slidably connected to the movable holes 9. A plurality of resistance grooves 11 are fixedly connected to the inner wall of the placement groove at equal intervals. The resistance grooves 11 are engaged with the resistance block 10.

[0037] The end of the abutment block 10 away from the telescopic rod 7 is set to be conical, and the abutment block 10 is slidably arranged inside the placement groove.

[0038] In addition, one end of the abutment block 10 away from the telescopic rod 7 is rotatably connected to a plurality of balls 12 at equal distances.

[0039] In addition, sliders 13 are fixedly connected to both sides of the abutment block 10 , and sliding grooves are provided on both sides of the inner wall of the moving hole 9 . The sliders 13 match the shapes of the sliding grooves, and the sliders 13 are slidably connected to the sliding grooves.

[0040] When the connecting block 3 is connected to the base 2, the inner wall of the placement groove will contact the contact block 10. After the contact block 10 is under pressure, it will move inside the moving hole 9, thereby squeezing the telescopic rod 7 and the spring 8. The telescopic rod 7 and the spring 8 will deform and shrink after being stressed, generating elastic potential energy. When the contact block 10 moves to the position of the contact groove 11, the elastic potential energy of the spring 8 is released, thereby driving the contact block 10 to enter the inside of the contact groove 11, thereby completing the snap connection, achieving the purpose of strengthening the mechanical locking between the connecting block 3 and the base 2, reducing the risk of the thread loosening of the connecting block 3 body due to stress such as chewing, thereby improving the connection The stability and durability of the connecting block 3 are improved. When the resistance block 10 slides with the inner wall of the placement groove, a ball 12 is provided at one end of the resistance block 10. The ball 12 reduces the friction between the resistance block 10 and the inner wall of the placement groove, thereby ensuring the smooth movement of the connecting block 3 during the installation process. When the placement groove contacts the resistance block 10, the resistance block 10 is set to a cone shape. Under the action of the inclined surface of the resistance block 10, the resistance block 10 is forced to move. When the resistance block 10 moves, it is slidably connected with the slide groove through the slider 13. The slider 13 and the slide groove provide a guiding effect for the resistance block 10, so that the resistance block 10 can maintain the correct trajectory of movement.

[0041] Reference Figure 1 , Figure 2 and Figure 3 A side of the vertical plate 6 away from the telescopic rod 7 is fixedly connected with an oblique brace 14, and one end of the oblique brace 14 away from the vertical plate 6 is fixedly connected to the inner bottom wall of the cavity.

[0042] When the spring 8 retracts under force, the force will be transmitted to the vertical plate 6, the diagonal brace 14 and the connecting block 3 in sequence. By setting the diagonal brace 14 to be inclined, the connecting block 3, the vertical plate 6 and the diagonal brace 14 form a stable triangular structure, which can enhance the stability of the connection and effectively transmit force, thereby ensuring the normal use of the resistance block 10.

[0043] Reference Figure 1 , Figure 2 and Figure 3 A fixing pad 15 is fixedly connected to the inner bottom wall of the placement groove, and a plurality of convex points 16 are fixedly connected to the top of the fixing pad 15 at equal intervals.

[0044] When the connection block 3 is fixed to the base 2 , the friction between the base 2 and the connection block 3 can be increased by the protrusions 16 on the fixing pad 15 , thereby further improving the connection strength between the base 2 and the connection block 3 .

[0045] Reference Figure 1 , Figure 2 and Figure 3 The bottom sides of the connecting block 3 are fixedly connected with positioning blocks 17 , and the top sides of the base 2 are provided with positioning grooves 18 . The positioning blocks 17 are adapted to the shapes of the positioning grooves 18 , and the positioning grooves 18 and the positioning blocks 17 are slidably arranged.

[0046] When installing the denture body 1 , the denture body 1 can be accurately positioned by sliding the positioning block 17 and the positioning groove 18 .

[0047] Working principle: rotate and install the base 2 inside the gums, then place the threaded rod 5 in the fixing groove 4, and then rotate the connecting block 3 so that the connecting block 3 is fixed inside the placement groove, and finally fix the denture body 1 on the connecting block 3 by adhesive on the top of the connecting block 3, thereby completing the installation of the denture body 1. When the connecting block 3 is connected to the base 2, the inner wall of the placement groove will contact the interference block 10. The interference block 10 will move inside the moving hole 9 after being subjected to pressure, thereby squeezing the telescopic rod 7 and the spring 8. The telescopic rod 7 and the spring 8 will deform and shrink after being subjected to force, generating elastic potential energy. When the interference block 10 moves to the position of the interference groove 11, the elastic potential energy of the spring 8 is released, thereby driving the interference block 10 to enter the inside of the interference groove 11, thereby completing the snap connection and enhancing the mechanical locking between the connecting block 3 and the base 2.

[0048] When the spring 8 retracts under force, the force will be transmitted to the vertical plate 6, the diagonal brace 14 and the connecting block 3 in sequence. By setting the diagonal brace 14 to be inclined, the connecting block 3, the vertical plate 6 and the diagonal brace 14 form a stable triangular structure, which can enhance the stability of the connection and effectively transmit force, thereby ensuring the normal use of the resistance block 10. When the connecting block 3 is fixed to the base 2, the friction between the base 2 and the connecting block 3 can be increased through the protrusions 16 on the fixing pad 15, thereby further improving the connection strength between the base 2 and the connecting block 3.
