Description

Technical Field

[0001] This invention relates to the field of oral treatment technology, and in particular to a novel implant abutment. Background Technology

[0002] Dental implants, also known as implant prostheses, have become a routine treatment for restoring missing or damaged teeth. Their effects generally last for more than ten years. Currently, dental implants, specifically intraosseous fixed prostheses, are an advanced method for restoring missing autologous teeth in oral medicine. Therefore, the implant abutment is a crucial component connecting the implant to the crown. However, existing implant abutments still present some problems in practical use:

[0003] Existing implant abutments are connected to the abutment body via threaded grooves on the abutment connector for denture installation. However, after a period of use, this connection method may cause the abutment connector to rotate in the opposite direction, leading to loosening or detachment. This results in unstable implant fixation. Furthermore, when chewing food, the denture needs to withstand significant force, and the threaded grooves on the abutment connector are relatively thin. Therefore, with prolonged use, the threads on the abutment connector may deform, causing the denture to loosen or detach. Summary of the Invention

[0004] The purpose of this invention is to provide a novel implant abutment to solve the problems mentioned in the background art, such as the abutment connection part rotating in reverse after a period of use, causing the abutment connection part to loosen or fall off, resulting in unstable implant fixation, and the threads on the abutment connection part may deform with prolonged use of the denture, leading to loosening or detachment of the denture.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a novel implant abutment, comprising an abutment body, wherein an abutment connecting part is provided inside the abutment body, an implant connecting seat is fixedly installed on the surface of the abutment connecting part, and an anti-rotation mechanism, a locking mechanism and an anti-obstruction mechanism are provided on the surface of the implant connecting seat, and an anti-loosening mechanism and a squeezing mechanism are provided inside the abutment body;

[0006] The anti-rotation mechanism includes a limiting block, an elastic block, and a limiting groove. A collar is fixedly fitted at one end of the abutment connecting part near the implant connector. The elastic block is fixedly installed inside the collar, and the limiting block is slidably installed inside the collar. A limiting groove is formed at one end of the abutment body near the implant connector. The size of the limiting groove is adapted to the size of the limiting block. The elastic block can push the limiting block into the limiting groove to prevent the abutment connecting part from rotating in the opposite direction, which could cause the abutment connecting part to loosen or fall off.

[0007] As a preferred embodiment of the present invention, the anti-obstruction mechanism includes an adsorption block, a magnetic piece, and a pull rod. The pull rod is inserted into the interior of the implant connector and the collar. The implant connector has a movable cavity inside, and the adsorption block is slidably installed inside the movable cavity. A magnetic piece is snapped into the interior of the implant connector. One end of the pull rod located on the implant connector is fixedly installed on the surface of the adsorption block, and the end of the pull rod away from the adsorption block is fixedly installed on the surface of the limiting block. The pull rod is inserted into the interior of the elastic block. The adsorption block is made of an iron alloy. The magnetic piece can hold the adsorption block in place, so that the limiting block is located inside the collar. In this way, the abutment connection will not be blocked by the limiting block when rotating.

[0008] As a preferred embodiment of the present invention, the engagement mechanism includes an upper tooth block and a lower tooth block. An upper connecting plate is fixedly installed at the end of the abutment connection portion away from the implant connector, and an upper tooth block is fixedly installed on the side of the upper connecting plate away from the abutment connection portion.

[0009] As a preferred embodiment of the present invention, a lower connecting plate is fixedly installed at the bottom of the base body, and a plurality of lower tooth blocks are fixedly installed on the surface of the lower connecting plate. The upper tooth blocks and the lower tooth blocks are spliced ​​together, which has a better contact effect than the contact between the base connection part and the bottom of the base body, and reduces the gaps on the contact surface.

[0010] As a preferred embodiment of the present invention, the anti-loosening mechanism includes a limiting ring, a spring, and a pushing block. The limiting ring is fixedly installed at the bottom of the base body. A limiting hole is formed inside the limiting ring. A sliding groove is formed on the surface of the base connecting part. When the base connecting seat is fully inserted into the base body, the first guide block and the second guide block are pushed into the limiting hole. This can prevent the denture from loosening or falling off when the threads on the base connecting part are deformed.

[0011] As a preferred embodiment of the present invention, a slider is slidably installed inside the groove, the push block is fixedly installed on the surface of the slider, and the spring is fixedly installed on one end of the push block located inside the base connection portion.

[0012] As a preferred embodiment of the present invention, the end of the spring away from the push block is fixedly installed inside the base connection part, the push block is fixedly installed with a first guide block near the outside of the base connection part, and a second guide block is fixedly installed on the side of the first guide block. The cross-sectional shape of the first guide block is a right trapezoid, and the first guide block and the second guide block can be pushed into the limiting hole by the spring.

[0013] As a preferred embodiment of the present invention, the extrusion mechanism includes a connecting ring, an extrusion block and a soft pad. The connecting ring is fixedly installed inside the base body. A sliding groove is provided inside the connecting ring, and a sliding frame is slidably installed inside the sliding groove.

[0014] As a preferred embodiment of the present invention, a connecting rod is fixedly installed on the surface of the sliding frame, and a pressing block is fixedly installed at the end of the connecting rod away from the sliding frame. When the base connecting part enters the base body, the base connecting part can be clamped by the two pressing blocks to prevent the base connecting part from loosening longitudinally.

[0015] As a preferred embodiment of the present invention, the soft pad is fixedly installed on the surface of the extrusion block, and multiple protrusions are fixedly installed on the surface of the soft pad. Threaded grooves are opened in the interior of the connecting ring and on the surface of the base connection part. The hollow protrusions can increase the thrust provided by the soft pad to the extrusion block, thereby increasing the fixing effect.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The present invention, by setting a magnetic sheet, a limiting block, an elastic block and an adsorption block, can push the limiting block into the limiting groove through the elastic block, so as to prevent the base connection part from rotating in the opposite direction and causing the base connection part to loosen or fall off. The magnetic sheet can hold the adsorption block, so that the limiting block is located inside the collar, so that the base connection part will not be blocked by the limiting block when it rotates.

[0018] 2. By setting a spring, a first guide block, a second guide block, and a limiting ring, the present invention can prevent the denture from loosening or falling off when the base connecting seat is fully inserted into the base body, by pushing the first guide block and the second guide block into the limiting hole through the spring.

[0019] 3. By setting up extrusion blocks, soft pads and protrusions, when the base connecting part enters the base body, the base connecting part squeezes the two connecting rods in a direction away from each other. In this way, the base connecting part can be clamped by the two extrusion blocks to prevent longitudinal loosening of the base connecting part. The hollow protrusions can increase the pushing force provided by the soft pads to the extrusion blocks to enhance the fixing effect. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-6 This invention provides a novel implant abutment technical solution: Example

[0029] according to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a novel implant abutment includes an abutment body 1, an abutment connecting part 6 is provided inside the abutment body 1, an implant connector 5 is fixedly installed on the surface of the abutment connecting part 6, and an anti-rotation mechanism, a locking mechanism and an anti-obstruction mechanism are provided on the surface of the implant connector 5. An anti-loosening mechanism and a squeezing mechanism are provided inside the abutment body 1.

[0030] The anti-rotation mechanism includes a limiting block 208, an elastic block 207, and a limiting groove 209. A collar 202 is fixedly sleeved on one end of the abutment connection part 6 near the implant connector 5. The elastic block 207 is fixedly installed inside the collar 202. The limiting block 208 can be pushed into the limiting groove 209 by the elastic block 207. The limiting block 208 is slidably installed inside the collar 202. A limiting groove 209 is opened on one end of the abutment body 1 near the implant connector 5. The size of the limiting groove 209 is adapted to the size of the limiting block 208, so that the limiting block 208 is inserted into the limiting groove 209. This can prevent the abutment connection part 6 from rotating in the opposite direction, which would cause the abutment connection part 6 to become loose or fall off. The anti-obstruction mechanism includes an adsorption block 205, a magnet 201, and a pull rod 203. The pull rod 203 is inserted into the inside of the implant connector 5 and the collar 202.

[0031] The implant connector 5 has a movable cavity 206 inside. The adsorption block 205 is slidably installed inside the movable cavity 206. A magnet 201 is snapped into the inside of the implant connector 5. A pull rod 203 is fixedly installed at one end of the implant connector 5 and on the surface of the adsorption block 205. The end of the pull rod 203 away from the adsorption block 205 is fixedly installed on the surface of the limiting block 208. The pull rod 203 is inserted into the inside of the elastic block 207. The adsorption block 205 is made of iron alloy. The magnet 201 can hold the adsorption block 205, so that the limiting block 208 is located inside the collar 202, preventing the abutment connection part 6 from being blocked by the limiting block 208 when rotating.

[0032] The engagement mechanism includes an upper tooth block 210 and a lower tooth block 211. An upper connecting plate 204 is fixedly installed at the end of the abutment connection part 6 away from the implant connector 5. An upper tooth block 210 is fixedly installed on the side of the upper connecting plate 204 away from the abutment connection part 6. A lower connecting plate 212 is fixedly installed at the bottom inside the abutment body 1. Multiple lower tooth blocks 211 are fixedly installed on the surface of the lower connecting plate 212. The upper tooth block 210 and the lower tooth block 211 are spliced ​​together to have a better contact effect, which can effectively reduce the gaps on the contact surface.

[0033] In practical use, when connecting the abutment connecting part 6 to the abutment body 1, the abutment connecting part 6 needs to be rotated and inserted into the interior of the abutment body 1. After the abutment connecting part 6 is fully inserted into the interior of the abutment body 1, the limiting block 208 is aligned with the limiting groove 209. Since the magnetic piece 201 attracts the adsorption block 205, the limiting block 208 is located inside the collar 202. In this way, the abutment connecting part 6 will not be blocked by the limiting block 208 when rotating. Therefore, at this time, the magnetic piece 201 can be detached from the implant connector 5 to release the obstruction. In addition to fixing the adsorption block 205, the elastic block 207 in a compressed state can push the limiting block 208 into the limiting groove 209. This can prevent the base connecting part 6 from rotating in the opposite direction, which could cause the base connecting part 6 to loosen or fall off. When the base connecting part 6 is fully inside the base body 1, the upper tooth block 210 will engage with the lower tooth block 211, so that the upper tooth block 210 and the lower tooth block 211 are spliced ​​together. Compared with the contact between the base connecting part 6 and the bottom of the base body 1, the contact effect is better and the gaps on the contact surface are reduced. Example

[0034] Based on Example 1, such as Figure 4 and Figure 5 As shown, the anti-loosening mechanism includes a limiting ring 307, a spring 306, and a pushing block 302. The limiting ring 307 is fixedly installed inside the bottom of the base body 1. A limiting hole 308 is formed inside the limiting ring 307. A sliding groove 301 is formed on the surface of the base connecting part 6. A slider 305 is slidably installed inside the sliding groove 301. The pushing block 302 is fixedly installed on the surface of the slider 305. The spring 306 is fixedly installed at one end of the pushing block 302 inside the base connecting part 6. The end of the spring 306 away from the pushing block 302 is connected to the base connecting part 6. Internally fixed installation: the first guide block 303 and the second guide block 304 can be pushed into the limiting hole 308 by the spring 306. The first guide block 303 is fixedly installed on the circle near the outside of the base connecting part 6 of the pushing block 302. The second guide block 304 is fixedly installed on the side of the first guide block 303. The cross-sectional shape of the first guide block 303 is a right trapezoid. When the first guide block 303 and the second guide block 304 are inserted into the limiting hole 308, it can prevent the denture from loosening or falling off when the threads on the base connecting part 6 are deformed.

[0035] In practical use, when connecting the abutment connecting part 6 to the abutment body 1, the abutment connecting part 6 needs to be rotated and inserted into the abutment body 1. When the abutment connecting part 6 enters the abutment body 1, the inclined surfaces of the first guide block 303 and the second guide block 304 will contact and squeeze with the limiting ring 307, thereby squeezing the two first guide blocks 303 and the second guide blocks 304 into the interior of the abutment connecting part 6. At this time, the spring 306 is in a compressed state, allowing the abutment connecting seat to be smoothly inserted into the interior of the abutment body 1. When the abutment connecting seat is fully inserted into the abutment body 1, the first guide block 303 and the second guide block 304 are aligned with the limiting hole 308. At this time, the spring 306 can push the first guide block 303 and the second guide block 304 into the limiting hole 308. In this way, when the threads on the abutment connecting part 6 deform, it prevents the denture from becoming loose or falling out. Example

[0036] Based on Example 1, such as Figure 6 As shown, the extrusion mechanism includes a connecting ring 401, an extrusion block 404, and a soft pad 405. The connecting ring 401 is fixedly installed inside the base body 1. A sliding groove 407 is provided inside the connecting ring 401. A sliding frame 403 is slidably installed inside the sliding groove 407. A connecting rod 402 is fixedly installed on the surface of the sliding frame 403. An extrusion block 404 is fixedly installed at the end of the connecting rod 402 away from the sliding frame 403. The soft pad 405 is fixedly installed on the surface of the extrusion block 404. When the base connecting part 6 enters the base body 1, the base connecting part 6 can be clamped by the two extrusion blocks 404 to prevent the base connecting part 6 from loosening longitudinally. Multiple protrusions 406 are fixedly installed on the surface of the soft pad 405. The hollow protrusions 406 can increase the thrust provided by the soft pad 405 on the extrusion block 404 to increase the fixing effect. Threaded grooves are provided inside the connecting ring 401 and on the surface of the base connecting part 6.

[0037] In practical use, when connecting the abutment connecting part 6 to the abutment body 1, the abutment connecting part 6 needs to be rotated and inserted into the interior of the abutment body 1. When the abutment connecting part 6 enters the abutment body 1, the end of the abutment connecting part 6 located inside the abutment body 1 will be squeezed against the inclined surface of the compression block 404, thereby causing the two connecting rods 402 to move away from each other, so that the soft pad 405 is squeezed, deformed and tightly attached to the interior of the abutment body 1. In this way, the abutment connecting part 6 can be clamped by the two compression blocks 404 to prevent longitudinal loosening of the abutment connecting part 6 inside the abutment body 1. The hollow protrusion 406 can increase the pushing force provided by the soft pad 405 to the compression block 404, thereby increasing the fixation effect.

[0038] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
