Description

Technical Field

[0001] The present invention relates to the technical field of artificial tooth implantation, and in particular to an artificial tooth implant body and an artificial tooth with a self-locking structure. Background Art

[0002] People's teeth will not be replaced after they reach adulthood. Due to certain lifestyle habits or external forces, teeth may fall out. In order to prevent gum atrophy and subsequent chewing errors, denture implants are needed.

[0003] A dental implant is an artificial root replacement used in restorative dentistry to support the restoration of a similar tooth or group of teeth. Implants are usually made of metal (usually titanium) or ceramic (usually zirconia) and have external threads that engage in a hole drilled, reamed, or otherwise formed in the jawbone.

[0004] In order to enhance the stability of the implant, the side wall of the implant is processed with an external thread. During the implantation process, it is necessary to use a drill to gradually expand the hole on the alveolar bone from fine to coarse, and then use tapping to process the internal thread. However, in actual use, due to the patient's long-term chewing activities, the gap between the implant and the hole is prone to increase, causing the implant to shake, affecting the patient's comfort and use.

[0005] To this end, the present invention provides a denture implant and a denture with a self-locking structure. Summary of the invention

[0006] In order to make up for the shortcomings of the prior art, the technical problem raised in the background technology that due to the patient's long-term chewing activity, the gap between the implant and the hole is easily increased, resulting in implant shaking, affecting the patient's comfort and use.

A sliding limit groove is provided on the vertical side of the protruding block, and the sliding limit groove is used for cooperating with the vertical limit block. A rotation limit groove is provided on the lateral side of the protruding block, and the rotation limit groove is used for cooperating with the clamping block. The clamping block passes through the through hole and is located in the rotation limit groove, that is, the clamping plate can maintain a rotation connection with the protruding block and can also drive the connecting sleeve to slide along the protruding block. A central rod is fixedly connected to the upper side of the base, and the central rod is six A prism, a central platform is slidably connected to the central rod, and the central platform fits the central rod. A pressure plate is fixedly connected to the upper side of the central platform, and the pressure plate is used to facilitate the operator to press the central platform so that the central platform reaches the area to be locked. The outer side of the central platform is evenly fixedly connected to the mounting rod, and a push plate is rotatably connected to the mounting rod. When the central platform moves downward, the length of the push plate cannot be changed, so the connecting sleeve can be pushed. A clamping plate is fixedly connected to the lower side of the push plate, and a connecting sleeve is rotatably connected to the inner side of the clamping plate. The connecting sleeve is slidably connected to the protruding block, and a top plate is fixedly connected to one side of the connecting sleeve, and the top plate is used to contact the circular hole opened on the alveolar bone, thereby fixing the implant body in the alveolar bone.

[0008] Preferably, a through hole is opened on the outer side of the connecting sleeve, a vertical limit block is fixedly connected to the inner side of the connecting sleeve, a clamping block is fixedly connected to the clamping plate, the clamping block passes through the through hole and enters into the rotation limit groove on the protruding block, and the vertical limit block is located in the sliding limit groove on the protruding block, so as to make the movement of the connecting sleeve along the protruding block more stable.

[0009] Preferably, a first locking block is fixedly connected to the central rod, and the first locking block consists of two parts, one part is a spring, and the other part is a column fixedly connected to the spring and used to be inserted into the first locking hole. In a normal state, the first locking block is located inside the central rod due to the obstruction of the central platform. When the central platform is displaced to the point where the first locking hole and the first locking block coincide, the first locking block loses its obstruction and the spring releases its elastic potential energy to allow the first locking block to enter the first locking hole, thereby locking the position of the central rod and the central platform. A first locking hole is provided on the inner side of the central platform. The positions of the first locking hole and the first locking block correspond and are the same in number, which are used to lock the position of the central platform and the central rod.

[0010] Preferably, the push plate is provided with a stabilizing structure inside the implant body, which is used to further fix the implant body when it is twisted or subjected to greater pressure and becomes unstable. The upper side of the implant body is threadedly connected to a connecting base, and a base mounting hole is provided on the inner side of the central rod. The bottom of the base mounting hole has an internal thread for threaded connection with the connecting base. The position of the implant body in the alveolar bone is fixed by the expanded implant body, thereby locking the position of the implant body, avoiding the loosening of the implant body caused by the patient's chewing, thereby affecting the patient's subsequent use experience and effect.

[0011] Preferably, the stabilizing structure includes a locking platform slidably connected to the push plate, the locking platform is rotatably connected to a connecting rod, the main body of the locking platform is a square frame, nested in the push plate, and the upper side of the locking platform is fixedly connected to a round hole rotatably connected to the connecting rod, and the lower side of the locking platform is provided with a hole for the second locking block to pass through, one end of the connecting rod is rotatably connected to a mounting frame, the mounting frame is used to install a cone head and a round rod, the mounting frame is located on one side of the top plate, the mounting frame is fixedly connected to a round rod, and the round rod passes through the top plate.

One side of the locking platform is fixedly connected with a bottom plate, and a second locking block is installed on the bottom plate. The second locking block is connected to the bottom plate through a spring. When the second locking block is not in use, it will be blocked by the push plate, and the spring is in a compressed state. When the locking platform moves to the second locking hole opened on the push plate, the spring of the second locking block will release elastic potential energy to push the second locking block into the second locking hole. The push plate is provided with a second locking hole for locking the position of the locking platform and the push plate through the second locking block. The cone head with a taper can be better connected to the alveolar bone, thereby providing more friction to the implant body, and the friction force is stronger due to the stronger extrusion force, resulting in a stronger static friction force, so that the device can resist the patient's stronger external force on the denture, which is convenient for the patient to chew harder food.

[0013] Preferably, the connecting base includes a base body, the base body is columnar as a whole, a connecting screw is fixedly connected to the lower side of the base body, the connecting screw can be threadedly connected to the base mounting hole, and U-shaped grooves are evenly opened on the outer side of the base body.

[0015] A denture is applied to the above-mentioned implant with a self-locking structure, the denture is arranged on the upper side of the connection base, the denture is an artificial crown, which is the part protruding from the gums, and the position of the denture corresponding to the third locking block is provided with a groove of the same shape as the third locking block, which is used for the denture to be installed on the connection base. The use of the third locking block can quickly install and disassemble the denture, so that it becomes convenient when the denture needs to be replaced or maintained, and improves the user's comfort.

[0016] The beneficial effects of the present invention are as follows: the denture implant and denture with a self-locking structure described in the present invention fix the position of the implant body in the alveolar bone by expanding the implant body, thereby locking the position of the implant body and avoiding the loosening of the implant body due to the patient's chewing, thereby affecting the patient's subsequent use experience and use effect.

[0017] The denture implant and denture with a self-locking structure described in the present invention can be better tightly connected with the alveolar bone through the tapered cone head, thereby providing more friction to the implant body. The friction force is stronger due to the stronger extrusion force, resulting in stronger static friction, so that the device can resist the patient's stronger external force on the denture, making it easier for the patient to chew harder food.

[0021] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0022] Embodiment 1 See also Figures 1 to 5 , a denture implant body with a self-locking structure according to an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4, including a planting body 1, a base 11 is arranged on the bottom side of the planting body 1, and protruding blocks 12 are evenly fixed on the outer side of the base 11. There are six protruding blocks 12 in total, which are in the shape of a cuboid and fixed on each rectangular surface of the hexahedron on the base 11. A sliding limit groove 13 is provided on the vertical side of the protruding block 12, and the sliding limit groove 13 is used to cooperate with the vertical limit block 114. A rotation limit groove 14 is provided on the lateral side of the protruding block 12, and the rotation limit groove 14 is used to cooperate with the clamping block 115. The clamping block 115 passes through the through hole 113 and is located in the rotation limit groove 14, that is, the clamping plate 110 can maintain a rotation connection with the protruding block 12 while also driving the connecting sleeve 111 to slide along the protruding block 12. A central rod 15 is fixedly connected to the upper side of the base 11, and the central rod 15 is a hexagonal prism. A central platform 16 is slidably connected, and the central platform 16 fits the central rod 15. A pressure plate 17 is fixedly connected to the upper side of the central platform 16. The pressure plate 17 is used to facilitate the operator to press the central platform 16 so that the central platform 16 reaches the area to be locked. The outer side of the central platform 16 is evenly fixedly connected to the mounting rod 18, and a push plate 19 is rotatably connected to the mounting rod 18. When the central platform 16 moves downward, because the length of the push plate 19 cannot be changed, the connecting sleeve 111 can be pushed. A clamping plate 110 is fixedly connected to the lower side of the push plate 19, and a connecting sleeve 111 is rotatably connected to the inner side of the clamping plate 110. The connecting sleeve 111 is slidably connected to the protruding block 12, and a top plate 112 is fixedly connected to one side of the connecting sleeve 111. The top plate 112 is used to contact the circular hole opened on the alveolar bone, thereby fixing the implant body 1 in the alveolar bone.

[0023] Please refer to Figure 4 A through hole 113 is opened on the outer side of the connecting sleeve 111, and a vertical limit block 114 is fixedly connected to the inner side of the connecting sleeve 111. A clamping block 115 is fixedly connected to the clamping plate 110. The clamping block 115 passes through the through hole 113 and enters the rotation limit groove 14 on the extending block 12. The vertical limit block 114 is located in the sliding limit groove 13 on the extending block 12, which is used to make the movement of the connecting sleeve 111 along the extending block 12 more stable.

[0024] Please refer to Figure 5A first locking block 116 is installed on the central rod 15. The first locking block 116 consists of two parts, one part is a spring, and the other part is a column fixedly connected to the spring, which is used to be inserted into the first locking hole 117. Under normal conditions, due to the obstruction of the central platform 16, the first locking block 116 is located inside the central rod 15. When the central platform 16 moves to the position where the first locking hole 117 and the first locking block 116 coincide, the first locking block 116 loses its obstruction, which will cause the spring to release its elastic potential energy, allowing the first locking block 116 to enter the first locking hole 117, thereby locking the position of the central rod 15 and the central platform 16. A first locking hole 117 is provided on the inner side of the central platform 16. The positions of the first locking hole 117 and the first locking block 116 correspond and are the same in number, which are used to lock the positions of the central platform 16 and the central rod 15.

[0025] Please refer to Figure 1 A stabilizing structure 2 is provided on the push plate 19. The stabilizing structure 2 is inside the implant body 1 and is used to further fix the implant body 1 when it is twisted or subjected to a large pressure and becomes unstable. A connecting base 3 is threadedly connected to the upper side of the implant body 1. A base mounting hole 118 is provided on the inner side of the central rod 15. The bottom of the base mounting hole 118 has an internal thread for threaded connection with the connecting base 3.

[0026] Specifically, when the implant body 1 needs to be implanted in the patient, a hole needs to be drilled at the implantation location first. The diameter of the drilled hole needs to be slightly smaller than the diameter of the implant body 1 after it is opened. Then the implant body 1 is placed in the hole, and the operator presses the pressing plate 17. Since the pressing plate 17 is fixedly connected to the central platform 16, the pressing plate 17 will drive the central platform 16 to move downward. The central platform 16 moving downward will drive the push plate 19 to rotate. Since the length of the push plate 19 cannot be changed, the rotation of the push plate 19 will drive the connecting sleeve 111 located on the protruding block 12 to slide along the protruding block 12. During the process, the vertical limit block 114 located in the sliding limit groove 13 can make The sliding direction of the connecting sleeve 111 is more stable, and the block 115 located in the rotation limit groove 14 allows the card plate 110 to freely adjust the angle between the connecting sleeve 111, until the position of the first locking hole 117 on the central platform 16 coincides with the position of the first locking block 116 on the central rod 15, so that the end spring of the first locking block 116 releases the elastic potential energy, and the column part of the first locking block 116 is ejected into the first locking hole 117, completing the position locking between the central rod 15 and the central platform 16. Even if the implant body 1 remains in the open state, the top plate 112 in this state will tightly press against the opening of the alveolar bone, so that the device as a whole remains stable. The position of the implant body 1 in the alveolar bone is fixed by the expanded implant body 1, so as to lock the position of the implant body 1, and avoid the loosening of the implant body 1 caused by the patient's chewing, thereby affecting the patient's subsequent use experience and use effect.

[0027] Embodiment 2 See also Figures 6 to 8 , which is another embodiment of the present invention, please refer to Figure 6 , Figure 7 The stabilizing structure 2 includes a locking platform 21 slidably connected to the push plate 19, and a connecting rod 22 is rotatably connected to the locking platform 21. The main part of the locking platform 21 is a square frame, which is nested on the push plate 19, and a round hole that can be rotatably connected to the connecting rod 22 is fixedly connected to the upper side of the locking platform 21, and a hole for the second locking block 27 to pass through is opened on the lower side of the locking platform 21. One end of the connecting rod 22 is rotatably connected to a mounting frame 23, and the mounting frame 23 is used to install a cone head 25 and a round rod 24. The mounting frame 23 is located on one side of the top plate 112, and a round rod 24 is fixedly connected to the mounting frame 23, and the round rod 24 passes through the top plate 112.

[0028] Please refer to Figure 7 The end of the round rod 24 is fixedly connected with a cone head 25, which is located in a square groove pre-opened on the top plate 112 and is used to stabilize the implant body 1 so that the cone head 25 can extend out of the outside of the top plate 112 to support the hole in the alveolar bone. One side of the locking platform 21 is fixedly connected with a bottom plate 26, and a second locking block 27 is installed on the bottom plate 26. The second locking block 27 is connected to the bottom plate 26 through a spring. When the second locking block 27 is not in use, it will be blocked by the push plate 19, and the spring is in a compressed state. When the locking platform 21 moves to the second locking hole 28 opened on the push plate 19, the spring of the second locking block 27 will release the elastic potential energy to push the second locking block 27 into the second locking hole 28. The push plate 19 is provided with a second locking hole 28, which is used to lock the position of the locking platform 21 and the push plate 19 through the second locking block 27.

[0029] Specifically, when the implant body 1 has been fully opened, the stabilizing structure 2 needs to be further opened, that is, the operator needs to continue to push the locking platform 21 located on the push plate 19, and the locking platform 21 slides along the push plate 19. The movement of the locking platform 21 will cause the angle between the connecting rod 22, the locking platform 21 and the mounting frame 23 to change. Because the length of the connecting rod 22 remains unchanged, when the locking platform 21 moves downward along the push plate 19, the connecting rod 22 will push the mounting frame 23 to move toward the top plate 112, thereby pushing the round rod 24 and the cone head 25 to the outside of the top plate 112 until the cone head 25 fits tightly into the alveolar bone. The cone head 25 with a taper can be better connected to the alveolar bone, thereby providing more friction to the implant body 1, and the friction force is stronger due to the stronger extrusion force, resulting in a stronger static friction force, so that the device can resist the patient's stronger external force on the denture 4, which is convenient for the patient to chew harder food.

[0030] Please refer to Figure 8The connecting base 3 includes a base body 31, which is columnar as a whole. A connecting screw 32 is fixedly connected to the lower side of the base body 31, and the connecting screw 32 can be threadedly connected to the base mounting hole 118. U-shaped grooves 33 are evenly opened on the outer side of the base body 31.

[0031] Please refer to Figure 8 An active block 34 is slidably connected to the inner side of the U-shaped groove 33, a straight plate 35 is fixedly connected to one side of the active block 34, a third locking block 36 is fixedly connected to one side of the straight plate 35, the two transverse square grooves of the U-shaped groove 33 have different lengths, the longer transverse square groove is used to accommodate the active block 34, and the shorter transverse square groove is used to accommodate the third locking block 36, and the straight plate 35 is fixedly connected to the inner wall of the U-shaped groove 33 by a spring.

[0032] Please refer to Figure 8 , a denture is applied to the above-mentioned implant with a self-locking structure, the denture 4 is arranged on the upper side of the connecting base 3, the denture 4 is an artificial tooth crown, which is the part extending out of the gums, and a groove of the same shape as the third locking block 36 is opened at the position corresponding to the denture 4 and the third locking block 36, which is used for the denture 4 to be installed on the connecting base 3.

[0033] Specifically, after the implant body 1 is implanted and tightened, the connecting base 3 can be installed into the implant body 1 through the bottom connecting screw 32 and the base mounting hole 118 in the implant body 1, thereby completing the connection between the implant body 1 and the connecting base 3, and then the denture 4 can be directly inserted into the upper end of the connecting base 3. Because the insertion of the denture 4 can squeeze the third locking block 36, the third locking block 36 is retreated into the U-shaped groove 33, until the preset groove of the denture 4 coincides with the position of the third locking block 36, the spring at the end of the third locking block 36 will push the third locking block 36 out and lock the denture 4 and the connecting base 3. If the denture 4 needs to be replaced, the operator only needs to use a 90° straight rod to push the active block 34 located in the U-shaped groove 33, thereby driving the third locking block 36 to enter the U-shaped groove 33, so that the third locking block 36 releases the lock on the denture 4, which can facilitate the replacement of the denture 4. The third locking block 36 can be used to quickly install and disassemble the denture 4, so that it is convenient to replace or maintain the denture 4, thereby improving the user's comfort.

[0034] How it works When the implant body 1 needs to be implanted in the patient, a hole needs to be drilled at the implantation location first. The diameter of the drilled hole needs to be slightly smaller than the diameter of the implant body 1 after it is opened. Then the implant body 1 is placed in the hole, and the operator presses the pressing plate 17. Since the pressing plate 17 is fixedly connected to the central platform 16, the pressing plate 17 will drive the central platform 16 to move downward. The central platform 16 moving downward will drive the push plate 19 to rotate. Since the length of the push plate 19 cannot be changed, the rotation of the push plate 19 will drive the connecting sleeve 111 located on the extending block 12 to slide along the extending block 12. During the process, the vertical limit block 114 located in the sliding limit groove 13 can make the connecting sleeve 111 slide along the extending block 12. The sliding direction of the sleeve 111 is more stable, and the block 115 located in the rotation limit groove 14 allows the clamping plate 110 to freely adjust the angle between the clamping plate 110 and the connecting sleeve 111 until the position of the first locking hole 117 on the central platform 16 coincides with the position of the first locking block 116 on the central rod 15, so that the end spring of the first locking block 116 releases the elastic potential energy, and the column part of the first locking block 116 bounces into the first locking hole 117, completing the position locking between the central rod 15 and the central platform 16. Even if the implant body 1 remains in the open state, the top plate 112 will tightly press against the opening of the alveolar bone in this state, so that the device as a whole remains stable. When the implant body 1 has been fully opened, the stabilizing structure 2 needs to be further opened, that is, the operator needs to continue to push the locking platform 21 on the push plate 19, and the locking platform 21 slides along the push plate 19. The movement of the locking platform 21 will cause the angle between the connecting rod 22, the locking platform 21 and the mounting frame 23 to change. Because the length of the connecting rod 22 remains unchanged, when the locking platform 21 moves downward along the push plate 19, the connecting rod 22 will push the mounting frame 23 to move toward the top plate 112, thereby pushing the round rod 24 and the cone head 25 to the outside of the top plate 112 until the cone head 25 fits tightly into the alveolar bone. After the implant body 1 is implanted and tightened, the connecting base 3 can be installed into the implant body 1 through the bottom connecting screw 32 and the base mounting hole 118 in the implant body 1, thereby completing the connection between the implant body 1 and the connecting base 3. Then the denture 4 can be directly inserted into the upper end of the connecting base 3. Because the insertion of the denture 4 can squeeze the third locking block 36, the third locking block 36 is retreated into the U-shaped groove 33 until the preset groove of the denture 4 coincides with the position of the third locking block 36. The spring at the end of the third locking block 36 will push the third locking block 36 out and lock the denture 4 and the connecting base 3. If the denture 4 needs to be replaced, the operator only needs to use a 90° straight rod to push the active block 34 located in the U-shaped groove 33, thereby driving the third locking block 36 to enter the U-shaped groove 33, so that the third locking block 36 releases the lock on the denture 4, which can facilitate the replacement of the denture 4.

[0035] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
