Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis technology, and in particular to a structure for preventing dentures from falling out. Background Technology

[0002] With the development of dental implant technology, implant dentures have gradually become a more ideal way of restoring teeth. The implant is inserted into the alveolar bone to provide stable support for the denture. Dentures are important medical instruments used to restore missing teeth, which can help patients restore chewing function, improve facial appearance and enhance speech ability.

[0003] Currently, traditional denture fixing methods mainly include two types: removable dentures and fixed dentures. Fixed dentures, commonly known as fixed false teeth, cannot be removed or worn by the patient themselves, while removable dentures, commonly known as removable false teeth, can be easily removed and worn by the patient. However, the connection structure of fixed dentures is not stable enough. Under long-term chewing force or external impact, the denture is prone to separating from the implant and falling out, affecting the patient's normal use and quality of life. Therefore, it is necessary to design a denture structure that prevents it from falling out. Utility Model Content

[0004] The purpose of this invention is to provide a denture structure that prevents dentures from falling out, so as to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A denture structure designed to prevent dislodgement includes an implant and a denture. The top of the implant has a downward-facing first threaded hole, into which a connecting component is screwed. The bottom of the denture has an upward-facing receiving groove, into which a magnet is disposed. The denture is snapped onto the top of the connecting component.

[0007] By adopting the above technical solution, the connecting component is firmly fixed in the implant by screwing it in, and then the connecting component is magnetically snapped to hold the denture firmly at its top, thereby preventing the denture from falling out.

[0008] In a further embodiment, the connecting assembly includes a circular plate and threaded rods. A downward-pointing threaded rod extends from the bottom center of the circular plate. The threaded rod is screwed to the implant through a first threaded hole. Multiple threaded rods are provided, with their bottom ends passing through the circular plate and the implant in sequence. Each threaded rod is screwed to both the circular plate and the implant. Each threaded rod has an elastic unit at its top end. The elastic unit includes a spring, a connecting rod, and a round buckle. The spring is sleeved on the connecting rod. Multiple round grooves are axially provided at the top end of the threaded rod. The proximal end of the spring is fixedly connected to the proximal end of the connecting rod. The proximal end of the connecting rod is fixedly connected to the round grooves. The centrifugal end of the spring is fixedly connected to the round buckle. The round buckle is snapped into the centrifugal end of the round groove. The centrifugal side of the round buckle passes through and extends to the outside of the round groove.

[0009] By adopting the above technical solution, after the connecting component is screwed into the implant through the bottom screw, the connecting component is firmly fixed to the implant through the arrangement of multiple threaded rods distributed around the top edge of the circular plate.

[0010] In a further embodiment, the centrifugal surface of the round buckle is an inclined plane, and the top width of the round buckle is greater than the bottom width of the round buckle.

[0011] In a further embodiment, the bottom end of the magnet is provided with a plurality of clearance grooves for accommodating round buckles.

[0012] In a further embodiment, the threaded rod includes a round rod portion and a threaded portion, the round rod portion being disposed on top of the threaded portion, and the round rod portion and the threaded portion being integrally formed.

[0013] By adopting the above technical solution, the circular groove is set on the circular part of the threaded rod to avoid interfering with the threaded rod screwing into the circular plate and the implant.

[0014] In a further embodiment, the top of the circular plate is provided with a plurality of second threaded holes that extend vertically, and the top of the implant is provided with a plurality of downward threaded grooves. The number of the second threaded holes and the number of threaded grooves are the same as the number of threaded rods. The axes of the second threaded holes and the threaded grooves are collinear, and the second threaded holes and the threaded grooves are adapted to the threaded rods.

[0015] By adopting the above technical solution, the connecting component and the implant are connected by threads. A screw extends from the center of the bottom of the circular plate of the connecting component. The screw is screwed into the first threaded hole at the top of the implant to achieve a preliminary and stable connection. At the same time, the top of the circular plate has a second threaded hole that is the same number as the threaded rod and runs vertically through it. The top of the implant has a corresponding downward threaded groove. The axes of the second threaded hole and the threaded groove are collinear and both are adapted to the threaded rod. Multiple threaded rods pass through the circular plate and the implant in sequence. The threaded rods further strengthen the connection strength between the connecting component and the implant by screwing with the second threaded hole and the threaded groove, so that the connecting component is firmly fixed in the implant. Then, the connecting component and the denture are connected and fixed by a combination of magnetic snap-fit ​​and mechanical snap-fit. A magnet is provided in the receiving groove at the bottom of the denture and engages with the circular snap-fit ​​of the connecting component. The system generates a magnetic attraction that attracts the denture to the top of the connecting component. Furthermore, each threaded rod has an elastic unit at its threaded end, including a spring, a connecting rod, and a snap ring. The snap ring has a beveled centrifugal surface, and the width of its top end is smaller than its bottom end, facilitating the insertion of the denture and connecting component. When the denture approaches, the snap ring is compressed, the spring is compressed, and the snap ring retracts into its groove. After the denture is in place, the snap ring pops out under the spring's elasticity and engages in the clearance groove at the bottom of the magnet, forming a mechanical snap-lock to prevent the denture from falling off vertically. By utilizing the stability of the threaded connection and combining the reliability of magnetic attraction and mechanical snap-lock, the connection strength between the denture and the implant is greatly enhanced, effectively reducing the probability of the denture falling off due to external forces during use, thereby improving the stability and safety of denture use.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. The denture is securely fixed to the implant by screwing in the connecting components, and then the connecting components are magnetically snapped to hold the denture firmly at its top, which can prevent the denture from falling out. Attached Figure Description

[0026] like Figures 1-4 As shown, an anti-dislodgement denture structure includes an implant 1 and a denture 2. The top of the implant 1 is provided with a downward-facing first threaded hole, and a connecting component 3 is screwed into the first threaded hole. The bottom of the denture 2 is provided with an upward-facing receiving groove, and a magnet 4 is provided inside the receiving groove. The denture 2 is snapped onto the top of the connecting component 3.

[0027] The connecting assembly 3 includes a circular plate 31 and threaded rods 32. A downward-pointing screw 33 extends from the bottom center of the circular plate 31. The screw 33 is screwed to the implant 1 through a first threaded hole. Multiple threaded rods 32 are provided, with their bottom ends passing through the circular plate 31 and the implant 1 in sequence. Each threaded rod 32 is screwed to both the circular plate 31 and the implant 1. Each threaded rod 32 has an elastic unit 34 at its top. The elastic unit 34 includes a spring 341, a connecting rod 342, and a round buckle 343. The round buckle 343 is an armature, and its centrifugal end attracts the magnet 4. The spring 341 is sleeved on the connecting rod 342. Multiple round grooves are axially provided at the top of the threaded rod 32. The proximal end of the spring 341 is fixedly connected to the proximal end of the connecting rod 342, and the proximal end of the connecting rod 342 is fixedly connected to the round grooves. The centrifugal end of the spring 341 is fixedly connected to the round buckle 343, which is snapped into the centrifugal end of the round groove. The centrifugal side of the round buckle 343 passes through and extends to the outside of the round groove. The centrifugal surface of the round buckle 343 is an inclined surface, and the top width of the round buckle 343 is greater than the bottom width. The bottom end of the magnet 4 is provided with multiple clearance grooves for accommodating the round buckle 343. The threaded rod 32 includes a round rod part and a threaded part. The round rod part is located on top of the threaded part, and the round rod part and the threaded rod 33 part are integrally formed. The top end of the round plate 31 is provided with multiple second threaded holes that pass through vertically. The top end of the implant 1 is provided with multiple downward threaded grooves. The number of second threaded holes and threaded grooves is the same as the number of threaded rods 32. The axes of the second threaded holes and threaded grooves are collinear, and the second threaded holes and threaded grooves are adapted to the threaded rods 32.

[0028] Specific implementation process: The connecting component 3 and the implant 1 are connected by threads. A screw 33 extends from the center of the bottom of the circular plate of the connecting component 3. The screw 33 is screwed into the first threaded hole at the top of the implant 1 to achieve a preliminary and stable connection. At the same time, the top of the circular plate 31 has a second threaded hole with the same number of threads as the threaded rods and extending vertically. The top of the implant 1 has a downward threaded groove. The axes of the second threaded hole and the threaded groove are collinear and both are adapted to the threaded rods 32. Multiple threaded rods 32 pass through the circular plate 31 and the implant 1 in sequence. The threaded rods 32 further strengthen the connection strength between the connecting component 3 and the implant 1 by screwing with the second threaded hole and the threaded groove, so that the connecting component 3 is firmly fixed in the implant 1. Then, the connecting component 3 and the denture 2 are connected and fixed by a combination of magnetic snap-fit ​​and mechanical snap-fit. A magnet is provided in the receiving groove at the bottom of the denture 2, which generates a magnetic attraction with the circular snap 343 of the connecting component. The denture 2 is attached to the top of the connecting component 3. In addition, each threaded rod 32 has an elastic unit 34 on its threaded part, including a spring 341, a connecting rod 342 and a round buckle 343. The centrifugal surface of the round buckle 343 is inclined, and the width of the top of the round buckle 343 is smaller than the width of its bottom end, which facilitates the insertion of the denture 2 and the connecting component 3. When the denture 2 is close, the round buckle 343 is squeezed, the spring 341 is compressed, and the round buckle 343 retracts into the round groove. After the denture 2 is installed in place, the round buckle 343 pops out under the elastic force of the spring 341 and is locked into the clearance groove at the bottom of the magnet 4, forming a mechanical buckle to prevent the denture 2 from falling off in the vertical direction. By utilizing the stability of the threaded connection and combining the reliability of magnetic adsorption and mechanical buckle, the connection strength between the denture and the implant can be greatly enhanced, effectively reducing the probability of the denture falling off due to external force during use, thereby improving the stability and safety of denture use.
