Description

Technical Field

[0001] This application relates to the field of dental implant technology, and more specifically, to an implant with a honeycomb porous surface. Background Technology

[0002] Dental implants, also known as dental implants, are surgically inserted into the alveolar bone of the upper or lower jaw to locate the missing tooth. After the surgical wound heals, a prosthetic tooth is then fitted onto the implant. With improved living standards, the demand for dental restoration is increasing. More and more people are choosing immediate implantation after tooth loss to quickly restore their chewing ability.

[0003] A tissue-level dental implant system device with publication number CN214484682U is disclosed. By roughening the external thread surface of the dental implant, the roughness of the external thread tooth surface is increased, which effectively increases the surface area for the tooth surface to bond with the bone tissue, increases the friction coefficient between the implant surface and the bone tissue surface, and increases the initial retention state of the implant, resulting in better integration of the dental implant with the surrounding bone tissue.

[0004] Although this patent can improve the integration of the implant with the surrounding bone tissue, it only uses a single external thread to assemble with the alveolar bone, resulting in a small contact area between the implant and the alveolar bone. This leads to poor stability of the implant-bone integration and makes the implant prone to loosening. Utility Model Content

[0005] To address the aforementioned issues, this application provides an implant with a honeycomb porous surface.

[0006] The honeycomb-shaped porous surface implant provided in this application adopts the following technical solution:

[0007] A honeycomb-shaped porous implant includes an implant body, the outer wall of which is fixedly connected with implant threads, the thread pitch of which decreases from bottom to top.

[0008] Multiple guide grooves are provided on each end of the implantation thread to reduce implantation torque;

[0009] The implant body is composed of a honeycomb porous layer with hexagonal pores and a pore size of 100-500μm.

[0010] Through the above technical solutions, the implant threads and honeycomb porous layer enable the implant body to integrate more tightly with the bone tissue during long-term use, better withstand various mechanical loads in daily activities, reduce the occurrence of complications such as implant loosening and displacement, extend the service life of the implant body, reduce the risk and cost of secondary surgery for patients, and bring long-term reliable treatment results to patients.

[0011] Furthermore, a drill bit is fixedly connected to the bottom of the implant body, and multiple grooves are opened inside the drill bit.

[0012] Furthermore, the trench includes four sections, each with an arc-shaped section inside.

[0013] Through the above technical solution, bone chips generated during bone cutting can be discharged along the groove, avoiding the accumulation of bone chips around the drill bit and affecting its continued cutting. The arc-shaped part in the groove makes the flow of bone chips in the groove smoother, guiding the bone chips to be discharged efficiently along the arc trajectory, preventing bone chips from clogging the groove, and ensuring the continuous and efficient operation of the drill bit.

[0014] Furthermore, the outer wall of the drill bit is provided with multiple sets of raised grooves, with each set of raised grooves having multiple numbers, and each set of raised grooves being located between every two grooves.

[0015] Through the above technical solution, multiple sets of ridges play a stabilizing and guiding role in the implantation process. When the drill bit cuts into the bone and rotates to advance, the ridges are in close contact with the bone tissue surface. The ridges increase the friction between the drill bit and the bone tissue, making it less likely for the drill bit to slip during rotation.

[0016] Furthermore, the implant body has threaded holes inside for connection with the abutment.

[0017] Furthermore, the implant body has hexagonal holes inside, which are connected to threaded holes.

[0018] Furthermore, the guide grooves are spaced apart on the planting thread.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] (1) By setting the implant thread and honeycomb porous layer, the implant body can be more closely integrated with the bone tissue during long-term use, and can better withstand various mechanical loads in daily activities, reduce the occurrence of complications such as implant loosening and displacement, extend the service life of the implant body, reduce the risk and cost of secondary surgery for patients, and bring long-term reliable treatment effects to patients.

[0021] (2) In the process of cutting bone, the bone chips generated by this utility model can be discharged along the groove, avoiding the accumulation of bone chips around the drill bit and affecting its continued cutting. The arc-shaped part in the groove makes the flow of bone chips in the groove smoother, which can guide the bone chips to be discharged efficiently along the arc-shaped trajectory, prevent the bone chips from blocking the groove, and ensure the continuous and efficient operation of the drill bit.

[0022] (3) The multiple sets of ridges of this utility model play a stabilizing and guiding role in the implantation process. When the drill bit cuts into the bone and rotates to advance, the ridges are in close contact with the surface of the bone tissue. The ridges increase the friction between the drill bit and the bone tissue, making it less likely for the drill bit to slip when rotating. Attached Figure Description

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] Reference Figures 1-4 A honeycomb porous surface implant includes an implant body 1, and an implant thread 2 is fixedly connected to the outer wall of the implant body 1. The thread pitch of the implant thread 2 decreases from bottom to top.

[0030] Multiple guide grooves 3 are provided on each end of the implantation thread 2, and the multiple guide grooves 3 are used to reduce the implantation torque;

[0031] The implant body 1 is composed of a honeycomb porous layer 10. The pores on the honeycomb porous layer 10 are hexagonal in shape and the pore diameter is between 100-500μm.

[0032] When the implant body 1 begins to be implanted into the bone tissue, the relatively large thread pitch at the bottom makes it easier for the implant body 1 to cut into the bone. This is because the larger pitch reduces the resistance of the bone to the implant body 1 during the initial contact. As the implant body 1 gradually penetrates deeper into the bone tissue, the thread pitch gradually decreases. At this time, the engagement between the threads and the bone becomes tighter. With each rotation, the distance the implant body 1 advances is relatively reduced, but the contact area and friction with the bone increase, providing stronger anchoring force and ensuring that the stability of the implant body 1 gradually improves during the implantation process.

[0033] During the insertion of the implant body 1, when the implant body 1 encounters resistance from the bone, the edge of the guide groove 3 can cut into the bone first. With its sharp shape, it can locally break and separate the bone, dispersing the originally continuous bone resistance into multiple small parts. This changes the simple squeezing and friction mode between the implant body 1 and the bone into a combination of cutting and squeezing. This working method effectively reduces the torque that the implant body 1 needs to overcome as a whole, making it easier for the implant body 1 to rotate and penetrate deeper into the bone tissue.

[0034] When the dentist rotates the implant body 1, the implant thread 2 uses its spiral structure to convert the rotational force into a pushing force along the axial direction of the implant body 1, so that the implant body 1 can be precisely screwed into the alveolar bone or other implantation site bone tissue in the predetermined direction, guiding the implant body 1 into place smoothly.

[0035] The implant body 1 consists of a honeycomb porous layer 10. Its hexagonal pore structure is designed to mimic the microscopic pore morphology of natural bone tissue. After the implant body 1 is implanted into the human body, bone cells can migrate, attach, and proliferate along these regular pores. The hexagonal pores are arranged closely and regularly in space, ensuring sufficient porosity and providing relatively stable attachment sites for bone cells.

[0036] By reducing the thread spacing from bottom to top through the implant thread 2, the implant body 1 is provided with initial stability, from ease of operation at the beginning of implantation to strong anchoring force in the later stage. The special structure of the honeycomb porous layer 10 provides an ideal space for bone cells to attach and grow, which accelerates the ingrowth speed of bone tissue into the implant body 1 and shortens the time required for osseointegration.

[0037] By incorporating the implant thread 2 and the honeycomb porous layer 10, the implant body 1 integrates more tightly with the bone tissue during long-term use, better withstands various mechanical loads during daily activities, reduces the occurrence of complications such as implant loosening and displacement, extends the service life of the implant body 1, reduces the risk and cost of secondary surgery for patients, and brings long-term reliable treatment results to patients.

[0038] Reference Figures 1-3 The bottom of the implant body 1 is fixedly connected to a drill bit 4. The drill bit 4 has multiple grooves 5 inside. There are four grooves 5. The interior of each of the four grooves 5 is provided with an arc-shaped part 7. The outer wall of the drill bit 4 is provided with multiple sets of raised textures 6. The number of raised textures 6 in each set is set to multiple. Each set of raised textures 6 is located between every two grooves 5.

[0039] The main function of the drill bit 4 at the bottom of the implant is to assist in breaking through bone tissue during implantation, creating a suitable implantation path. When external force is applied to rotate and advance the implant downwards, the sharp edge of the drill bit 4 cuts into the bone. The four grooves 5 inside the drill bit 4 play a crucial role in chip removal. Bone chips generated during bone cutting can be discharged along the grooves 5, preventing bone chips from accumulating around the drill bit 4 and affecting its continued cutting. The arc-shaped part 7 within the groove 5 makes the flow of bone chips smoother, guiding them to be discharged efficiently along the arc-shaped trajectory, preventing bone chips from clogging the groove 5, and ensuring the continuous and efficient operation of the drill bit 4.

[0040] Multiple sets of ridges 6 located between every two grooves 5 play a stabilizing and guiding role during implant placement. When the drill bit 4 cuts into the bone and rotates to advance, the ridges 6 are in close contact with the bone tissue surface. The ridges 6 increase the friction between the drill bit 4 and the bone tissue, making it less likely for the drill bit 4 to slip during rotation.

[0041] Reference Figures 1-3 The implant body 1 has a threaded hole 8 inside, which is used to connect with the abutment. The implant body 1 also has a hexagonal hole 9 inside, which is connected to the threaded hole 8. The guide groove 3 is distributed at intervals on the implant thread 2.

[0042] When the abutment needs to be installed, the bottom of the abutment has matching external threads. The external threads of the abutment are screwed into the threaded hole 8 of the implant body 1. The tight engagement of the threads ensures a stable connection. The hexagonal hole 9 connects to the threaded hole 8, primarily serving to assist in installation and torque transmission. During the process of screwing the abutment into the threaded hole 8, the head of a hexagonal wrench is inserted into the hexagonal hole 9. Due to the excellent stability and torque transmission characteristics of the hexagonal geometry, turning the hexagonal wrench precisely transmits torque to the abutment, allowing it to be smoothly screwed into the threaded hole 8.

[0043] Working principle: First, the drill bit 4 at the bottom of the implant body 1 begins to function. When an external force is applied to rotate and push the implant downwards, the drill bit 4, with its sharp edge, cuts into the bone, creating a path for subsequent implant placement. At this time, the four grooves 5 inside the drill bit 4 and the arc-shaped part 7 therein discharge bone fragments generated from cutting the bone along the grooves 5. The arc-shaped part 7 ensures smooth flow of bone fragments, avoids blockage, and ensures continuous and efficient cutting by the drill bit 4. At the same time, the multiple sets of ridges 6 located between the grooves 5 are in close contact with the bone tissue, increasing friction, preventing the drill bit 4 from slipping, and also playing a stabilizing and guiding role, allowing the implant to advance in the predetermined direction.

[0044] Next, the implant threads 2 on the outer wall of the implant body 1 begin to dominate the implantation process. In the initial stage, the relatively large thread pitch at the bottom reduces the resistance of the bone to the implant body 1, making it easier for the implant body 1 to cut into the bone. As the implant body 1 gradually penetrates deeper, the thread pitch decreases from bottom to top, the threads and bone engage more tightly, the distance advanced per rotation decreases relatively, but the contact area and friction increase, providing stronger anchoring force and ensuring that the stability of the implant body 1 gradually improves. Furthermore, the guide grooves 3 spaced apart at the end of the implant threads 2 play a role when encountering bone resistance. Their edges cut into the bone first, dispersing the continuous bone resistance and changing the squeezing and friction mode into a combination of cutting and squeezing. This effectively reduces the torque that the implant body 1 needs to overcome as a whole, helping the implant body 1 to penetrate deeper into the bone tissue.

[0045] After the implant body 1 is implanted, the abutment installation can proceed after a period of time when the dental implant is installed. The implant body 1 has interconnected threaded holes 8 and hexagonal holes 9. When installing the abutment, the matching external thread at the bottom of the abutment is aligned with the threaded hole 8 of the implant body 1. The head of the hexagonal wrench is inserted into the hexagonal hole 9, and the wrench is turned. Due to the stability and good torque transmission characteristics of the hexagon, the torque is accurately transmitted to the abutment, allowing the abutment to be smoothly screwed into the threaded hole 8. A stable connection is achieved through the tight engagement of the threads. At this point, the entire implant implantation and abutment connection process is completed, laying the foundation for the subsequent installation of the prosthesis. The honeycomb porous layer 10 of the implant body 1 will continue to promote bone cell attachment and proliferation, accelerating osseointegration.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
