Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of dental implantation, and in particular relates to a dental implant system and a manufacturing device thereof. Background Art
[0002] The basic structure of the dental implant system includes the implant, abutment, connecting screw and upper crown. The implant is a structure implanted in the bone tissue, acting as a natural tooth root, and taking on functions such as support and retention. The abutment is the part located above the implant, passing through the gums and exposed in the mouth, and is the key structure connecting the upper crown and the lower implant. The connecting screw is a part that connects the abutment and the implant.
[0003] A dental implant system disclosed in publication number CN108852539B includes an implant with external threads and a base for connecting a crown, the implant having an implant center hole for inserting the base, a plurality of slots are arranged on the inner side wall surrounding the implant center hole, a bayonet that can be elastically buckled in the slot is arranged on the outer side wall of the base corresponding to each slot, the bayonet is arranged in a bayonet hole arranged on the outer side wall of the base, a magnetic connecting plate is arranged at the bottom of the bayonet, and a spring that supports the magnetic connecting plate is arranged at the bottom of the bayonet hole. The present invention provides a buckle structure so that the base can be easily buckled on the implant through the buckle structure. On the one hand, this buckle structure saves a structural component, and on the other hand, it can be disassembled and assembled without tools, the connection is convenient and fast, the buckle position is accurately positioned, and the operation is repeatable, which greatly reduces the pain caused to the patient.
[0004] However, the technical solution disclosed in the above invention has the following problems when used: when the implant and the base are fixed by the cooperation of the marble and the pit, the tightness of the buckle needs to be determined by the elastic force of the spring, so there are problems of unstable installation or difficult disassembly during use. When the abutment and the implant are fixed by the cooperation of the pin and the slot, although the stability between the abutment and the implant after fixation can be ensured, two magnetic suction methods are used when the abutment is disassembled from the implant. One method is to drive the magnet close to the magnetic suction plate through the rotation of the capstan in the center hole of the abutment, so that the pin is sucked out of the slot under the action of magnetic suction; the other method is to set an electromagnet in the center hole of the abutment, and provide power to the electromagnet so that the electromagnet and the magnetic suction plate can suck the slot out of the slot. Both methods are not only complex in structure, but also cannot be removed from the implant if any component fails during use, making it impossible to replace the abutment. The abutment can only be forcibly removed from the implant or the implant can only be removed, resulting in implantation failure and the need to start the implant again, which brings great psychological and physiological harm to the patient and increases the cost of dental implantation.
[0005] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention
[0006] The object of the present invention is to provide a dental implant system and a manufacturing device thereof, which can solve the problem that the implant and the base are inconvenient to be disassembled and assembled when a snap-fit connection is adopted.
[0007] In order to achieve the above object, a technical solution provided by a specific embodiment of the present invention is as follows:
[0008] A dental implant system, comprising:
[0009] The implant includes an implant body. The implant body is the foundation of the dental implant system, so the stability and strength of the implant body determine the success or failure of the dental implant. The implant body is provided with an outer layer and an inner layer. Usually, the implant body is made of pure titanium material, but the production cost of pure titanium material is high. Therefore, the implant body is composed of an outer layer and an inner layer, which increases the strength of the implant body and reduces its cost. The inner layer is provided with an implant center hole, which is used to install the components of the dental implant system.
[0010] The abutment includes an abutment body, which is a bridge in the dental implant system for installing the crown on the implant. The implantation of the tooth is completed by connecting the abutment body. The abutment body is provided with an upper abutment and a lower abutment. The upper abutment is used for installing the crown, and the lower abutment is installed in the implant so that the implant, the abutment and the crown can be installed together. The upper abutment and the lower abutment are provided with a center hole of the abutment in a through manner. The center hole of the abutment can not only reduce the weight of the abutment, but also be used for the installation of components.
[0011] The fixing assembly includes a mounting groove and a clamping groove. The mounting groove is provided on the side wall of the upper base, and the clamping groove is provided on the inner side wall of the inner layer. A clamping rod is slidably connected in the mounting groove, and one end of the clamping rod is placed in the clamping groove. When the base is sleeved on the implant, that is, when the lower base is sleeved in the center hole of the implant, the positions of the mounting groove and the clamping groove need to correspond, so that one end of the clamping rod in the mounting groove can slide in the clamping groove, so that the base can be stably installed on the implant under the action of the clamping rod.
[0012] The disassembly and assembly components include a push-disassembly and assembly component, a magnetic disassembly and assembly component, and a stretch-disassembly and assembly component. After the dental implant, if there are subsequent problems, the abutment may need to be removed from the implant. Therefore, the clamping rod needs to be retracted into the installation slot as a whole so that the clamping rod does not block the clamping slot, and the abutment can be removed from the implant. Therefore, in order to ensure that the clamping rod can be retracted into the installation slot by external force during use, a push-disassembly and assembly component, a magnetic disassembly and assembly component, and a stretch-disassembly and assembly component are provided. All three disassembly and assembly components can retract the clamping rod into the installation slot. Therefore, when any of the three components fails during use, the remaining two components can be used to retract the clamping rod into the installation slot to ensure that the abutment can be removed from the implant.
[0013] In one or more embodiments of the present invention, the outer layer and the inner layer are connected by cladding, the inner side wall of the outer layer is integrally formed with a plurality of first protrusions, the plurality of first protrusions are arranged on the inner side wall of the outer layer in an irregular manner, the outer side wall of the inner layer is integrally formed with a plurality of second protrusions, the plurality of second protrusions are arranged on the outer side wall of the inner layer in an irregular manner, and the first protrusion and the second protrusion are both arranged as pyramids. The outer layer and the inner layer constitute the implant body. Since the implant body needs to have sufficient strength and stability to ensure stability after implantation, the connection between the outer layer and the inner layer must be firm. By arranging the first protrusion and the second protrusion on the sides of the outer layer and the inner layer that contact each other, when the outer layer and the inner layer are connected by cladding, the first protrusion and the second protrusion are respectively inserted into the inner layer and the outer layer, so that the connection between the outer layer and the inner layer is firm. And the first protrusion and the second protrusion are both arranged as pyramids, so that the first protrusion and the second protrusion can increase the strength of the outer layer and the inner layer after connection, thereby ensuring the stability of the structure.
[0014] In one or more embodiments of the present invention, an external thread is provided on the outer wall of the outer layer, and the implant body is installed in the tooth bone through the external thread. An internal thread is provided on the upper side of the inner wall of the center hole of the base, and the outer layer is made of pure titanium material, and the inner layer is made of stainless steel material. In order to reduce the cost of the implant body and at the same time not affect the compatibility between the implant body and human bones, and ensure that the implant body is firmly installed on the tooth bone, the outer layer is made of pure titanium material for contact with human bones, and the inner layer is arranged on the inner side of the outer layer for connection to the base, so that the contact position between the implant body and the base is strong, ensuring stability during use.
[0015] In one or more embodiments of the present invention, the mounting groove and the clamping groove are provided in pairs, and the mounting groove and the clamping groove are symmetrically arranged. Since a pair of mounting grooves and the clamping groove are provided, a pair of clamping rods are provided. The pair of clamping rods are arranged in a symmetrical manner relative to the central axis of the implant body and the base body, so that the connection between the implant and the base can be ensured to be stable under the action of the pair of clamping rods, thereby ensuring the stability of the tooth when used after implantation. A compression spring is sleeved on the clamping rod, and a limiting ring is fixedly connected to the side wall of the compression spring. One end of the compression spring is installed on the limiting ring, and the other end of the compression spring is installed on a side wall of the clamping groove away from the opening, so that the clamping rod can be pushed to slide in the mounting groove into the clamping groove under the action of the elastic force of the compression spring. The limiting ring is not only used for the installation of the compression spring, but also the side wall of the limiting ring fits with the inner wall of the sliding groove, so that the stability of the clamping rod when sliding is limited by the limiting ring.
[0016] In one or more embodiments of the present invention, the end of the clamping rod away from the clamping groove is fixedly connected with a magnetic plate, a limiting plate is installed at the opening of the installation groove, and a sliding hole is arranged on the limiting plate. The end of the clamping rod away from the magnetic plate passes through the limiting plate through the sliding hole. The cooperation of the limiting plate and the limiting ring can limit the sliding distance of the clamping rod, so that the clamping rod can slide in the clamping groove, but will not fall out of the installation groove. At the same time, the cooperation of the sliding hole and the limiting ring on the limiting plate makes the clamping rod stable when sliding in the installation groove. The end of the clamping rod away from the magnetic plate is provided with a rounded corner, so that the corners of the clamping rod are rounded and convenient for sliding during disassembly and assembly. A buffer ring is installed in the clamping groove, and one end of the clamping rod with the rounded corner is placed in the buffer ring. Under the action of the buffer ring, the force between the clamping rod and the side wall of the clamping groove can be buffered, thereby buffering the force between the implant and the base.
[0017] In one or more embodiments of the present invention, the push-disassembly assembly includes a sliding groove, a pair of sliding grooves are provided, and the pair of implants are both opened in the inner layer in a penetrating manner, one end of the sliding groove is connected to the clamping groove, and the other end of the sliding groove is placed on the top of the inner layer. The end of the sliding groove placed on the top of the inner layer is covered with a sealing cover, and the upper end of the sliding groove can be sealed by the sealing cover to prevent the entry of impurities such as saliva during use. At the same time, the sealing cover can be installed by means of screw connection, etc., to ensure sealing and convenient disassembly. A push rod is slidably connected in the sliding groove, so that the push rod can slide in the sliding groove. In order to ensure that the push rod slides smoothly in the sliding groove, the side wall of the sliding groove can be polished to reduce the friction of the push rod sliding in the sliding groove. One end of the push rod is placed in the clamping groove, and one end of the push rod placed in the clamping groove is fixedly connected with a push plate, so that when the push rod slides downward in the sliding groove, the push plate can be pushed to move in the clamping groove, and when the push plate contacts the clamping rod, the clamping rod can be pushed to retract into the installation groove, so that the clamping rod is disengaged from the clamping groove, and the base can be removed from the inner side of the implant. The push rod is made of a metal material with good elasticity. Since the part of the push rod that is bent when sliding in the sliding groove, in order to prevent the bent part from affecting the sliding of the push rod, the push rod needs to be made of a metal material with good elasticity so that the push rod can be deformed accordingly when sliding. Since a pair of clamping rods need to be retracted into the installation groove at the same time when the base is removed from the implant, a pair of sliding grooves are provided. Therefore, in order to simultaneously push a pair of push rods to move during disassembly and assembly, so that a pair of clamping rods can be retracted into the installation groove at the same time, a special tool can be used to simultaneously extend into the sliding groove to push the push rod to move. At the same time, its components are simple in structure and easy to manufacture.
[0018] In one or more embodiments of the present invention, the magnetic disassembly assembly includes a magnetic block, the magnetic block is installed in the center hole of the base, the outer diameter of the magnetic block is smaller than the inner diameter of the center hole of the base, the upper end of the magnetic block is fixedly connected with a connecting rod, the upper end of the connecting rod is fixedly connected with a threaded block, the threaded block is threadedly connected to the base body through an internal thread, and the upper end of the threaded block is provided with a hexagonal slot. The threaded block is driven to rotate by a hexagonal wrench so that the threaded block moves upward in the center hole of the base, and the threaded block can drive the connecting rod to move upward, and the connecting rod drives the magnetic block to move upward. When the magnetic block moves to the same position as the magnetic plate, under the mutual adsorption of the magnetic block and the magnetic plate, the magnetic plate drives the clamping rod to move in the direction close to the magnetic block. When moving, the sealing cover can be compressed so that the clamping rod retracts into the installation groove. At the same time, the magnetic block will simultaneously adsorb a pair of magnetic plates on both sides, so that a pair of clamping rods retract into the installation groove at the same time, and the base can be removed from the implant. At the same time, its components have simple structures and are easy to manufacture.
[0019] In one or more embodiments of the present invention, the stretching and disassembling assembly includes an elastic rope, a through hole is provided between the center hole of the base and the clamping groove, the elastic rope passes through the through hole, one end of the elastic rope is fixedly connected to the side wall of the magnetic plate, and the other end of the elastic rope is placed in the center hole of the base and fixedly connected to an elastic block. Since the outer diameter of the magnetic block is smaller than the inner diameter of the center hole of the base, there is a certain distance between the outer wall of the magnetic block and the inner wall of the center hole of the base, and the distance is r. At the same time, the distance from the side of the elastic block away from the inner wall of the center hole of the base to the inner wall of the center hole of the base is greater than r, so that when the magnetic block is driven to move upward, the upper surface of the magnetic block will contact the lower surface of the elastic block, and the magnetic block will push the elastic block to move upward, and the elastic block will have a pulling force on the elastic rope, so that the elastic rope will pull the magnetic plate to move, and the magnetic plate will pull the clamping rod to retract. Therefore, under the action of a pair of elastic blocks, a pair of clamping rods can be retracted into the installation groove, so that the base can be removed from the implant. At the same time, because the elastic block can be deformed, when it is subjected to a large pulling force from the elastic rope, the elastic block will slip out of the gap between the magnetic block and the internal thread, so that the elastic block returns to its original position under the action of the elastic force. In order to ensure that the elastic block can slip out of the gap between the magnetic block and the internal thread when subjected to a large pulling force, the upper and lower corners of the magnetic block are rounded, so that the elastic block can return to its original position when the magnetic block moves up when removed and moves down when installed. At the same time, its components have a simple structure and are easy to manufacture.
[0020] In one or more embodiments of the present invention, a pair of limiting protrusions are fixedly connected to the side wall of the lower base, and the pair of limiting protrusions are arranged directly above a pair of mounting grooves. A pair of limiting grooves are opened on the inner side wall of the inner layer, and the pair of limiting grooves are arranged directly above a pair of clamping grooves. The pair of limiting protrusions are slidably connected in the pair of limiting grooves respectively. Through the cooperation of the limiting protrusions and the limiting grooves, the lateral movement and rotation of the base installed on the implant can be limited. At the same time, the cooperation of the limiting protrusions and the limiting grooves can locate the position of the base installed on the implant, and the lengths of the limiting protrusions and the limiting grooves are matched, so that when the limiting protrusion is slidably connected in the limiting groove and installed in place, the mounting groove and the clamping groove will correspond together, so that the clamping rod extends into the clamping groove to achieve fixation between the implant and the base.
[0021] A manufacturing device for a dental implant system, the manufacturing device comprising:
[0022] A computer-aided design system is used to create a three-dimensional model of an implant and abutment that matches the patient's oral cavity; a computer-aided design system is CAD, and medical staff use CAD to create a three-dimensional image of the implant system that matches the patient's oral cavity.
[0023] A computer-aided manufacturing system controls CNC milling and 3D printing to complete the preparation of the implant and the abutment based on the three-dimensional model of the implant and the abutment. The computer-aided manufacturing system is CAM. Through the three-dimensional map, CAM can control CNC milling and 3D printing equipment to make the implant and the abutment. When making the implant, the outer layer is first made by the 3D printing equipment, and the first protrusion on the inner wall of the outer layer needs to be made at the same time, and then the inner layer is clad on the inner wall of the outer layer by cladding.
[0024] Compared with the prior art, the present invention is provided with a push-disassembly component, a magnetic disassembly component and a stretching disassembly component. The three disassembly components can slide the clamping rod out of the clamping groove respectively, so that the clamping rod will not fix the base and the implant, and the base can be removed from the implant. Therefore, when any component of the three disassembly components fails, it will not affect the removal of the base from the implant, avoiding the problem of the base and the implant being unable to be removed and requiring the implant to be re-implanted. At the same time, each disassembly component has a simple structure and is easy to manufacture, which reduces the cost of the implant system and has good promotion value.

DETAILED DESCRIPTION
[0039] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0040] like Figure 1 to Figure 4 As shown, a dental implant system in one embodiment of the present invention includes an implant 1, an abutment 2, a fixing component 3 and a disassembly component 4.
[0041] like Figure 1 to Figure 5As shown, the implant 1 includes an implant body 11, which is the foundation of the dental implant system. Therefore, the stability and strength of the implant body 11 determine the success or failure of the dental implant. The implant body 11 is provided with an outer layer 12 and an inner layer 13. Usually, the implant body 11 is made of pure titanium material, but the production cost of pure titanium material is high. Therefore, the implant body 11 is composed of the outer layer 12 and the inner layer 13, which increases the strength of the implant body 11 and reduces its cost. An implant center hole 14 is provided in the inner layer 13, and the implant center hole 14 is used to install the components of the dental implant system.
[0042] like Figure 2 to Figure 4 As shown, an external thread 15 is provided on the outer wall of the outer layer 12 , and the implant body 11 is installed in the tooth bone through the external thread 15 .
[0043] Preferably, the outer layer 12 is made of pure titanium material, and the inner layer 13 is made of stainless steel material. In order to reduce the cost of the implant body 11, and at the same time not affect the compatibility between the implant body 11 and the human bone, and ensure that the implant body 11 is firmly installed on the tooth bone, the outer layer 12 is made of pure titanium material for contacting with the human bone, and the inner layer 13 is arranged on the inner side of the outer layer 12 for connecting with the base 2, so that the position where the implant body 11 contacts the base 2 is strong, ensuring stability during use.
[0044] like Fig.11 As shown, the outer layer 12 and the inner layer 13 are connected by cladding, and a plurality of first protrusions 16 are integrally formed on the inner wall of the outer layer 12, and the plurality of first protrusions 16 are irregularly arranged on the inner wall of the outer layer 12, and a plurality of second protrusions 17 are integrally formed on the outer wall of the inner layer 13, and the plurality of second protrusions 17 are irregularly arranged on the outer wall of the inner layer 13, and both the first protrusions 16 and the second protrusions 17 are arranged in the form of pyramids. The outer layer 12 and the inner layer 13 constitute the implant body 11. Since the implant body 11 needs to have sufficient strength and stability to ensure stability after implantation, the connection between the outer layer 12 and the inner layer 13 must be firm. By providing a first protrusion 16 and a second protrusion 17 on the sides where the outer layer 12 and the inner layer 13 contact each other, when the outer layer 12 and the inner layer 13 are connected by cladding, the first protrusion 16 and the second protrusion 17 are respectively inserted into the inner layer 13 and the outer layer 12, thereby making the connection between the outer layer 12 and the inner layer 13 firm.
[0045] Preferably, the first protrusion 16 and the second protrusion 17 are both configured as pyramids, so that the first protrusion 16 and the second protrusion 17 can increase the strength of the outer layer 12 and the inner layer 13 after being connected, thereby ensuring the stability of the structure.
[0046] like Figure 1 to Figure 5As shown, the abutment 2 includes an abutment body 21, which is a bridge in the dental implant system for installing the crown on the implant 1. The implantation of the tooth is completed through the connection of the abutment body 21. The abutment body 21 is provided with an upper abutment 22 and a lower abutment 23. The upper abutment 22 is used for installing the crown, and the lower abutment 23 is installed in the implant 1 so that the implant 1, the abutment 2 and the crown can be installed together. The upper abutment 22 and the lower abutment 23 are provided with an abutment center hole 24 in a through manner. The abutment center hole 24 can not only reduce the weight of the abutment 2, but also be used for the installation of components.
[0047] like Figure 4 and Figure 5 As shown, an internal thread 25 is provided on the upper side of the inner wall of the center hole 24 of the base, and the internal thread 25 is used for installing components.
[0048] like Figures 5 to 8 As shown, the fixing assembly 3 includes a mounting groove 31 and a clamping groove 32. The mounting groove 31 is provided on the side wall of the upper base 22, and the clamping groove 32 is provided on the inner side wall of the inner layer 13. A clamping rod 33 is slidably connected in the mounting groove 31, and one end of the clamping rod 33 is placed in the clamping groove 32. When the base 2 is sleeved on the implant 1, that is, when the lower base 23 is sleeved in the center hole 14 of the implant, it is necessary to make the positions of the mounting groove 31 and the clamping groove 32 correspond to each other, so that one end of the clamping rod 33 in the mounting groove 31 can slide in the clamping groove 32, so that the base 2 can be stably installed on the implant 1 under the action of the clamping rod 33.
[0049] like Figure 5 , Figure 7 and Fig. 9 As shown, a pair of mounting grooves 31 and a pair of clamping grooves 32 are provided, and the pair of mounting grooves 31 and the pair of clamping grooves 32 are symmetrically arranged. Since a pair of mounting grooves 31 and a pair of clamping grooves 32 are provided, there is a pair of clamping rods 33. The pair of clamping rods 33 are symmetrically arranged relative to the central axis of the implant body 11 and the base body 21, so that the connection between the implant 1 and the base 2 can be ensured to be stable under the action of the pair of clamping rods 33, thereby ensuring stability during use after the tooth is implanted.
[0050] like Figure 6 and Fig.10As shown, a compression spring 34 is sleeved on the clamping rod 33, and a limiting ring 35 is fixedly connected to the side wall of the compression spring 34. One end of the compression spring 34 is mounted on the limiting ring 35, and the other end of the compression spring 34 is mounted on a side wall of the clamping groove 32 away from the opening, so that the clamping rod 33 can be pushed to slide in the clamping groove 32 in the installation groove 31 under the action of the elastic force of the compression spring 34. The limiting ring 35 is not only used for installing the compression spring 34, but also the side wall of the limiting ring 35 is in contact with the inner wall of the sliding groove 41, so that the stability of the clamping rod 33 when sliding is limited by the limiting ring 35.
[0051] like Figure 6 and Fig.10 As shown, the end of the clamping rod 33 away from the clamping groove 32 is fixedly connected to the magnetic plate 36, and a limit plate 37 is installed at the opening of the installation groove 31. The limit plate 37 is provided with a sliding hole. The end of the clamping rod 33 away from the magnetic plate 36 passes through the limit plate 37 through the sliding hole. The cooperation of the limit plate 37 and the limit ring 35 can limit the stability of the clamping rod 33 when sliding, so that the clamping rod 33 can slide in the clamping groove 32 without falling out of the installation groove 31. At the same time, through the cooperation of the sliding hole on the limit plate 37 and the limit ring 35, the clamping rod 33 is stable when sliding in the installation groove 31. The end of the clamping rod 33 away from the magnetic plate 36 is provided with a rounded corner 39, so that the corners of the clamping rod 33 are rounded, which is convenient for sliding during disassembly and assembly. A buffer ring 38 is installed in the clamping groove 32, and one end of the clamping rod 33 with a rounded corner 39 is placed in the buffer ring 38. Under the action of the buffer ring 38, the force between the clamping rod 33 and the side wall of the clamping groove 32 can be buffered, thereby buffering the force between the implant 1 and the base 2.
[0052] like Figure 4 As shown, the disassembly assembly 4 includes a push disassembly assembly, a magnetic disassembly assembly, and a stretch disassembly assembly. After the tooth is implanted, if there are problems later, the base 2 may need to be removed from the implant 1. Therefore, the clamping rod 33 needs to be retracted into the installation groove 31 as a whole, so that the clamping rod 33 does not block the clamping groove 32, so that the base 2 can be removed from the implant 1. Therefore, in order to ensure that the clamping rod 33 can be retracted into the installation groove 31 by external force during use, a push disassembly assembly, a magnetic disassembly assembly, and a stretch disassembly assembly are provided. The three disassembly assemblies can retract the clamping rod 33 into the installation groove 31. Therefore, when any of the three assemblies fails during use, the remaining two assemblies can be used to retract the clamping rod 33 into the installation groove 31 to ensure that the base 2 can be removed from the implant 1.
[0053] like Figures 5 to 8As shown, the push disassembly assembly includes a sliding groove 41, and a pair of sliding grooves 41 are provided. The pair of implants 1 are both opened in the inner layer 13 in a penetrating manner. One end of the sliding groove 41 is connected to the clamping groove 32, and the other end of the sliding groove 41 is placed on the top of the inner layer 13. The sliding groove 41 is placed on the top of the inner layer 13. The end of the inner layer 13 is covered with a sealing cover 44. The upper end of the sliding groove 41 can be sealed by the sealing cover 44 to prevent the entry of impurities such as saliva during use. At the same time, the sealing cover 44 can be installed by screwing or other methods to ensure sealing and convenient disassembly. A push rod 42 is slidably connected in the sliding groove 41, so that the push rod 42 can slide in the sliding groove 41. In order to ensure that the push rod 42 slides smoothly in the sliding groove 41, the side wall of the sliding groove 41 can be polished to reduce the friction of the push rod 42 sliding in the sliding groove 41.
[0054] like Figure 6 and Figure 8 As shown, one end of the push rod 42 is placed in the clamping groove 32, and one end of the push rod 42 placed in the clamping groove 32 is fixedly connected with a push plate 43, so that when the push rod 42 slides downward in the sliding groove 41, it can push the push plate 43 to move in the clamping groove 32, and when the push plate 43 contacts the clamping rod 33, it can push the clamping rod 33 back into the installation groove 31, so that the clamping rod 33 is disengaged from the clamping groove 32, and the base 2 can be removed from the inner side of the implant 1. The push rod 42 is made of a metal material with good elasticity. Since the push rod 42 has a bent portion when sliding in the sliding groove 41, in order to prevent the bent portion from affecting the sliding of the push rod 42, the push rod 42 needs to be made of a metal material with good elasticity so that the push rod 42 can be deformed accordingly when sliding. Since the pair of clamping rods 33 need to be retracted into the installation groove 31 at the same time when the base 2 is removed from the implant 1, and a pair of sliding grooves 41 are provided, in order to simultaneously push the pair of push rods 42 to move during disassembly, so as to simultaneously retract the pair of clamping rods 33 into the installation groove 31, a special tool can be used to simultaneously extend into the sliding groove 41 to push the push rods 42 to move. The components of the simultaneous push disassembly assembly assembly are simple in structure and easy to manufacture.
[0055] like Figure 5 and Figure 6As shown, the magnetic disassembly and assembly component includes a magnetic block 45, which is installed in the center hole 24 of the base. The outer diameter of the magnetic block 45 is smaller than the inner diameter of the center hole 24 of the base. The upper end of the magnetic block 45 is fixedly connected with a connecting rod 46, and the upper end of the connecting rod 46 is fixedly connected with a threaded block 47. The threaded block 47 is threadedly connected to the base body 21 through the internal thread 25, and the upper end of the threaded block 47 is provided with a hexagonal groove 48. The threaded block 47 is rotated by a hexagonal wrench, so that the threaded block 47 moves upward in the center hole 24 of the base, and the threaded block 47 can drive the connecting rod 46 to move upward, and the connecting rod 46 drives the magnetic block 45 to move upward. When the magnetic block 45 moves to the same position as the magnetic plate 36, the magnetic plate 36 drives the clamping rod 33 to move in the direction close to the magnetic block 45 under the mutual adsorption of the magnetic block 45 and the magnetic plate 36. During the movement, the sealing cover 44 can be compressed, so that the clamping rod 33 is retracted into the installation groove 31. At the same time, the magnetic block 45 will simultaneously adsorb a pair of magnetic plates 36 on both sides, so that a pair of clamping rods 33 are simultaneously retracted into the installation groove 31, and the base 2 can be removed from the implant 1. At the same time, the components of the magnetic disassembly assembly assembly have a simple structure and are easy to manufacture.
[0056] like Figure 5 , Figure 6 and Fig.10As shown, the stretching and disassembly assembly includes an elastic rope 410, a through hole 49 is opened between the base center hole 24 and the clamping groove 32, the elastic rope 410 passes through the through hole 49, one end of the elastic rope 410 is fixedly connected to the side wall of the magnetic attraction plate 36, and the other end of the elastic rope 410 is placed in the base center hole 24 and fixedly connected to the elastic block 411. Since the outer diameter of the magnetic block 45 is smaller than the inner diameter of the abutment center hole 24, there is a certain distance between the outer wall of the magnetic block 45 and the inner wall of the abutment center hole 24, which is r. At the same time, the distance from the side of the elastic block 411 away from the inner wall of the abutment center hole 24 to the inner wall of the abutment center hole 24 is greater than r, so that when the magnetic block 45 is driven to move upward, the upper surface of the magnetic block 45 will contact the lower surface of the elastic block 411, and the magnetic block 45 will push the elastic block 411 to move upward, and the elastic block 411 will have a pulling force on the elastic rope 410, so that the elastic rope 410 will pull the magnetic plate 36 to move, and the magnetic plate 36 will pull the clamping rod 33 to retract. Therefore, under the action of a pair of elastic blocks 411, the pair of clamping rods 33 can be retracted into the installation groove 31, so that the abutment 2 can be removed from the implant 1. At the same time, since the elastic block 411 can be deformed, when subjected to a large pulling force from the elastic rope 410, the elastic block 411 will come out of the gap between the magnetic block 45 and the internal thread 25, so that the elastic block 411 returns to its original position under the action of the elastic force. In order to ensure that the elastic block 411 can come out of the gap between the magnetic block 45 and the internal thread 25 when subjected to a large pulling force, the upper and lower corners of the magnetic block 45 are rounded, so that the elastic block 411 can return to its original position when the magnetic block 45 moves up when removed and moves down when installed. At the same time, the components of the stretching and disassembling assembly have a simple structure and are easy to manufacture.
[0057] like Figure 4 As shown, a pair of limiting protrusions 310 are fixedly connected to the side walls of the lower base 23, and the pair of limiting protrusions 310 are arranged directly above the pair of mounting grooves 31. A pair of limiting grooves 311 are opened on the inner side walls of the inner layer 13, and the pair of limiting grooves 311 are arranged directly above the pair of snap-in grooves 32. The pair of limiting protrusions 310 are slidably connected in the pair of limiting grooves 311 respectively. Through the cooperation of the limiting protrusion 310 and the limiting groove 311, the lateral movement and rotation of the base 2 installed on the implant 1 can be limited. At the same time, the cooperation of the limiting protrusion 310 and the limiting groove 311 can locate the position of the base 2 installed on the implant 1, and the lengths of the limiting protrusion 310 and the limiting groove 311 are matched, so that when the limiting protrusion 310 is slidably connected in the limiting groove 311 and installed in place, the installation groove 31 and the clamping groove 32 will correspond together, so that the clamping rod 33 extends into the clamping groove 32, thereby realizing the fixation between the implant 1 and the base 2.
[0058] When in use, the implant body 11 is installed in the tooth bone through the external thread 15. After the implant body 11 and the tooth bone are stably fused, the base 2 needs to be installed on the implant 1. During installation, the lower end of the lower base 23 is sleeved in the center hole 14 of the implant, so that the limiting protrusion 310 is slidably connected to slide in the limiting groove 311. When the limiting protrusion 310 slides into place in the limiting groove 311, the clamping rod 33 will enter the clamping groove 32 under the push of the compression spring 34, so that the up and down movement of the base 2 installed on the implant 1 can be limited under the action of the clamping rod 33, so that the base 2 and the implant 1 are stable after installation; when the base 2 needs to be removed from the implant 1, the base 2 can be removed from the implant 1 by using one of the pushing disassembly assembly, magnetic disassembly assembly and stretching disassembly assembly.

[0061] Computer-aided manufacturing system, the computer-aided manufacturing system controls CNC milling and 3D printing according to the three-dimensional model of the implant 1 and the base 2 to complete the preparation of the implant 1 and the base 2. The computer-aided manufacturing system is CAM. Through the three-dimensional map, CAM can control CNC milling and 3D printing equipment to manufacture the implant 1 and the base 2. When manufacturing the implant 1, the outer layer 12 is first manufactured by the 3D printing equipment, and the first protrusion 16 on the inner wall of the outer layer 12 needs to be manufactured at the same time, and then the inner layer 13 is clad on the inner wall of the outer layer 12 by cladding.
