Description

Technical Field

[0001] This utility model relates to the field of planting bridge technology, specifically a personalized planting bridge that is easy to install and remove screws. Background Technology

[0002] An implant bridge, also known as a Malone bridge, is a type of dental implant restoration structure. It uses a bridge-like approach to fill missing teeth with dentures. The Malone bridge is based on dental implants, which involves first fixing multiple implants into the alveolar bone in the mouth, then constructing and fixing the Malone bridge onto the implants, and finally bonding the crowns to the Malone bridge.

[0003] For example, in the announcement number CN216876656U, there is a dental implant bridge. This dental implant bridge is made of a single component. When the size of one component is off, only that component needs to be replaced, which is convenient for maintenance and replacement. It will not cause pressure or friction on the gums, resulting in gum damage. Through the cooperation of the first clamping plate, the second clamping plate and the limiting hole, the fixing rod can be limited to prevent the fixing rod from detaching from the implant and causing the bridge body to loosen.

[0004] In the above-described implant bridge, when the prosthesis is installed in the bridge, the screw at the bottom of the prosthesis engages with the dental implant via threaded transmission, thereby fixing the prosthesis to the dental implant. Simultaneously, two sets of retaining plates are located at the bottom of the screw. After the screw is fully inserted into the dental implant, the two sets of retaining plates rotate and unfold, engaging with the dental implant to fix the prosthesis and prevent the screw at the bottom of the prosthesis from rotating and detaching from the dental implant. However, because the retaining plates cannot be folded after unfolding, it is impossible to separate the dental implant and screw after the screw and dental implant are installed. Furthermore, because the threaded hole on the dental implant is similar in diameter to the screw, it is difficult for the screw to enter the threaded hole of the dental implant during installation. Utility Model Content

[0005] The purpose of this invention is to provide a personalized implant bridge that facilitates screw installation and removal, addressing the issues raised in the background section regarding existing implant bridges. In these bridges, the prosthesis is fixed to the implant via a screw at the bottom of the prosthesis, which engages with the implant through threaded transmission. The screw has two sets of retaining plates at its base. After the screw is fully inserted into the implant, these plates rotate and unfold, engaging with the implant to secure it and prevent the screw from rotating and detaching. However, because the retaining plates cannot be folded after unfolding, the implant and screw cannot be separated after installation. Furthermore, because the threaded hole on the implant is similar in diameter to the screw, the screw has difficulty entering the implant's threaded hole during installation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a personalized implant bridge that facilitates screw installation and removal, comprising a bridge body and a screw body. Multiple sets of dental implants are fixedly connected to the bottom of the bridge body, and multiple sets of dentures are provided on the top of the bridge body. A screw body is fixedly connected to the bottom of each denture. A tapered hole is provided on the top of the bridge body. The outer side of the screw body is threaded to the dental implant. The outer bottom of the screw body is tapered. A safety limiting mechanism is provided at the bottom of the screw body, including a locking block that slides inside the screw body. A limit release mechanism is provided on one side of the bridge body.

[0007] Furthermore, one side of the locking block is rotatably connected to a connecting rod a via a rotating shaft, and the inside of the dental implant is provided with an annular limiting groove that matches the locking block. One end of the connecting rod a is rotatably connected to a connecting block via a rotating shaft.

[0008] Furthermore, the outer side of the connecting block is slidably connected to the screw body, and the bottom of the connecting block abuts against a spring a, and the bottom of the spring a abuts against the screw body.

[0009] Furthermore, the limit release mechanism includes a silicone membrane fixedly connected to one side of the cable tray body, a push plate provided on one side of the silicone membrane, and a push rod fixedly connected to one side of the push plate.

[0010] Furthermore, a spring b is sleeved on the outer side of the push rod, one end of the spring b abuts against the push plate, and the other end of the spring b abuts against the bridge frame body.

[0011] Furthermore, the screw body has a groove inside, and a connecting rod is slidably connected inside the groove. One end of the connecting rod is rotatably connected to a connecting rod b via a rotating shaft. One end of the connecting rod b is rotatably connected to a pressure rod via a rotating shaft. The outer side of the pressure rod is slidably connected to the screw body, and the bottom of the pressure rod is fixed to the connecting block.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the personalized implant bridge that facilitates screw disassembly and assembly connects the denture to the bridge body by threading the screw body at the bottom of the denture with the threaded hole in the bridge body. When the denture is fully inserted into the dental implant, the safety limiting mechanism will limit the screw body to prevent it from rotating. The limiting release mechanism can release the limiting of the screw body, thereby facilitating the disassembly of the screw body.

[0013] 1. By aligning the screw body at the bottom of the denture with the tapered hole at the top of the bridge body, the difficulty of alignment is reduced. When the two sets of locking blocks at the end of the screw body contact the tapered hole, they will move back into the screw body. When the locking blocks move into the annular limiting groove inside the dental implant, spring a pushes the locking blocks to move and engage with the annular limiting groove, thereby completing the limiting of the screw body. At this time, the screw body will not rotate arbitrarily.

[0014] 2. By pushing the silicone membrane, the push plate on one side moves, which in turn drives the push rod to move the connecting rod. The connecting rod then drives the connecting rod b on one side to rotate, causing the connecting rod b to push the pressure rod downward. When the pressure rod moves downward, it causes the locking block to move and disengage from the annular limiting groove inside the dental implant. At this time, the screw body can be rotated to disengage from the bridge body and the dental implant. Attached Figure Description

[0022] 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.

[0023] Example 1: Please refer to Figures 1-3This utility model provides the following technical solution: a personalized implant bridge that facilitates screw installation and removal, comprising a bridge body 1 and a screw body 4. Multiple sets of dental implants 2 are fixedly connected to the bottom of the bridge body 1, and multiple sets of dentures 3 are provided on the top of the bridge body 1. The bottom of each denture 3 is fixedly connected to the screw body 4. A tapered hole 5 is provided on the top of the bridge body 1. The outer side of the screw body 4 is threaded to the dental implant 2. The outer side of the bottom of the screw body 4 is tapered. A safety limiting mechanism is provided at the bottom of the screw body 4, including a locking block 6 that slides inside the screw body 4. This personalized implant bridge, which facilitates screw installation and removal, allows for the installation of dentures 3 onto the bridge body 1 and dental implants 2 during implantation, followed by the placement of the dental implants 2 into the patient's oral cavity.

[0024] Please see Figures 3-6 One side of the locking block 6 is rotatably connected to a connecting rod a7 via a rotating shaft. The dental implant 2 has an annular limiting groove inside that matches the locking block 6. One end of the connecting rod a7 is rotatably connected to a connecting block 9 via a rotating shaft. The outer side of the connecting block 9 is slidably connected to the screw body 4. The bottom of the connecting block 9 abuts against a spring a8, and the bottom of the spring a8 abuts against the screw body 4. When installing the denture 3, the screw body 4 at the bottom of the denture 3 is aligned with the tapered hole 5 at the top of the bridge body 1. The tapered hole 5 has a larger opening, making alignment easier. After alignment, the screw can be rotated. The screw body 4 is threadedly driven to the bridge body 1. When the two sets of locking blocks 6 at the end of the screw body 4 contact the tapered hole 5, they move and push the connecting rod a7 on one side to rotate. The connecting rod a7 will drive the connecting block 9 to move down, so that the connecting block 9 squeezes the spring a8 at the bottom. As the screw body 4 continues to rotate, the locking block 6 will move into the annular limiting groove inside the dental implant 2. At this time, the spring a8 will reset and push the locking block 6 to move and engage with the annular limiting groove, thereby completing the limiting of the screw body 4. At this time, the screw body 4 will not rotate arbitrarily and will be disengaged from the bridge body 1 and the dental implant 2.

[0025] The above operations facilitate the quick installation of the screw body 4 and limit its movement to prevent rotation.

[0026] Example 2:

[0027] Please see Figures 3-6Based on Embodiment 1, a limit release mechanism for facilitating the disassembly of the screw body 4 is also disclosed. Its specific structure is as follows: A limit release mechanism is provided on one side of the cable tray body 1. The limit release mechanism includes a silicone membrane 10 fixedly connected to one side of the cable tray body 1. A push plate 11 is provided on one side of the silicone membrane 10, and a push rod 13 is fixedly connected to one side of the push plate 11. A spring b12 is sleeved on the outer side of the push rod 13. One end of the spring b12 abuts against the push plate 11, and the other end of the spring b12 abuts against the cable tray body 1. A sliding groove is provided inside the screw body 4, and a connecting rod 14 is slidably connected inside the sliding groove. One end of the connecting rod 14 is rotatably connected to a connecting rod b15 via a rotating shaft. One end of the connecting rod b15 is rotatably connected to a pressure rod 16 via a rotating shaft. The outer side of the pressure rod 16 is slidably connected to the screw body 4, and the bottom of the pressure rod 16 is fixed to a connecting block 9.

[0028] Please see Figures 3-6 This personalized implant bridge, which facilitates screw removal and installation, allows for the removal of the screw body 4 from the bridge body 1 and the dental implant 2. By pushing the silicone membrane 10, a push plate 11 on one side moves. The push plate 11 compresses a spring b12 on one side, causing a push rod 13 to move into the screw body 4. This, in turn, pushes the connecting rod 14, which in turn rotates a connecting rod b15 on one side. This causes the connecting rod b15 to push the pressure rod 16 downwards. When the pressure rod 16 moves downwards, it causes the locking block 6 to move and disengage from the annular limiting groove inside the dental implant 2. At this point, the screw body 4 can be rotated to disengage from the bridge body 1 and the dental implant 2, thus completing the removal of the screw body 4.
