Description

Technical Field

[0001] This utility model belongs to the field of dental implant technology, specifically a healing abutment for dental implants. Background Technology

[0002] Dental implants are an important technology in modern oral restoration, bringing good news to many patients with missing teeth. Through surgical intervention, an artificial tooth root is implanted into the alveolar bone at the site of the missing tooth. The implant is usually made of biocompatible titanium or titanium alloy, which integrates tightly with the alveolar bone after implantation, much like a natural tooth root anchored in the alveolar bone, providing stable support for subsequent restoration. Once the implant and alveolar bone have completed osseointegration, the healing abutment plays a crucial role in the entire implant restoration process. After the implant is implanted into the alveolar bone and has initially healed, the healing abutment is installed on top of the implant. Its main function is to guide the gingival tissue to grow and shape around it, forming healthy and aesthetically pleasing gums. Then, the abutment connecting the implant to the crown is installed. Finally, a custom-made crown that matches the patient's oral environment and adjacent teeth is installed, thus completing the entire implant restoration process. Dental implants not only greatly restore the chewing function of teeth, allowing patients to enjoy various foods, but also have an aesthetic appearance almost indistinguishable from natural teeth, do not damage adjacent teeth, and have a long lifespan.

[0003] Existing healing abutments for dental implants have the following shortcomings: They offer poor sealing between the abutment and the implant root and lack gingival protection. The existing abutments rely on a conical locking structure for sealing, with the inner cone at the bottom of the abutment engaging with the conical groove at the top of the implant to form a mechanical seal. However, in the complex oral environment, the conical contact surface between the abutment and the implant root is prone to loosening, creating gaps in the previously tight seal. This allows bacteria and food debris to enter the implant root, deteriorating the oral environment and affecting the implant's effectiveness. Furthermore, the lack of gingival protection leaves the sutured gums exposed, making them susceptible to irritation, delaying wound healing, increasing the risk of implant failure, and causing significant pain and inconvenience for patients. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a healing abutment for dental implants, which solves the problems of poor sealing between existing healing abutments and artificial tooth roots and lack of gingival protection.

[0006] As a further embodiment of this utility model: the top of the base head is provided with an internal hexagonal connection hole.

[0007] As a further embodiment of this utility model: the protective component includes a hexagonal prism, which is disposed within an internal hexagonal connection hole 1.

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] like Figures 1-5 As shown, this utility model provides a technical solution:

[0024] A healing abutment for dental implants includes an artificial tooth root 1. The artificial tooth root 1 has a connecting hole at its top, and an abutment connecting portion 2 is disposed within the connecting hole. A sealing frustum 3 is fixedly connected to the top of the abutment connecting portion 2. A sealing groove is formed on the sealing frustum 3, and a sealing ring 4 is disposed within the sealing groove. A sealing disc 5 is fixedly connected to the top of the sealing frustum 3. An abutment neck 6 is disposed on the top of the sealing disc 5, and an abutment head 7 is disposed on the top of the abutment neck 6. A protective component is disposed on the top of the abutment head 7. The artificial tooth root 1 can be surgically implanted into the alveolar bone to provide stable support for subsequent restoration. The abutment connecting portion 2 can connect to the artificial tooth root 1 through the connecting hole at the top of the artificial tooth root 1, and the sealing frustum 3 can be embedded into the connecting hole at the top of the artificial tooth root 1. A solid physical barrier is initially constructed, effectively preventing foreign objects such as bacteria and food debris from entering the oral cavity. The sealing ring 4 is squeezed by the inner wall of the connection hole at the top of the artificial tooth root 1. The compressed sealing ring 4 perfectly fills the tiny gap between the sealing frustum 3 and the connection hole at the top of the artificial tooth root 1, greatly enhancing the sealing effect. The sealing disc 5 covers the top of the artificial tooth root 1. The neck of the abutment 6 can guide the growth of gingival tissue. The head of the abutment 7 protrudes from the gingival tissue, guiding the gingival tissue to form a good shape during the healing period, creating favorable conditions for the subsequent installation of the restorative abutment and crown. The protective component can protect the sutured gingiva, prevent the tongue from touching the gingiva, reduce the risk of gingival wound infection, and allow the gingiva to heal in a relatively stable and safe environment.

[0025] The top of the base head 7 is provided with an internal hexagonal connection hole 8. The internal hexagonal connection hole 8 can facilitate the installation and removal between the base connection part 2 and the artificial tooth root 1. At the same time, the protective component is connected to the base head 7 through the internal hexagonal connection hole 8.

[0026] The protective assembly includes a hexagonal prism 9, which is disposed within an internal hexagonal connector hole 8. The hexagonal prism 9 is adapted to the internal hexagonal connector hole 8. A movable groove 10 is provided at the bottom of the hexagonal prism 9. A pair of pins 11 are slidably connected to the hexagonal prism 9. A spring 12 is fitted around the outer periphery of each pair of pins 11. A conical frustum 13 is fixedly connected to the close end of each pair of pins 11. A threaded rod 14 is threadedly connected to the hexagonal prism 9. A second conical frustum 15 is coaxially fixedly connected to the bottom of the threaded rod 14. A rotating block 16 is coaxially fixedly connected to the top of the threaded rod 14. An internal hexagonal connector hole 17 is provided at the top of the rotating block 16. A protective plate 18 is fixedly connected to the outer periphery of the hexagonal prism 9. A groove 17 is provided on the protective plate 18. Multiple through slots. In the initial state, spring 12 pushes the first conical frustum 13, causing the pin 11 to retract into the hexagonal prism 9, with a pair of conical frustums 13 abutting each other. During installation, the hexagonal prism 9 is inserted into the first internal hexagonal connection hole 8, and a special tool is inserted into the second internal hexagonal connection hole 17, causing the rotating block 16 to rotate. The rotating block 16 causes the threaded rod 14 to rotate and descend on the hexagonal prism 9. The threaded rod 14 causes the second conical frustum 15 to move together. The second conical frustum 15 squeezes the pair of first conical frustums 13, causing the pair of first conical frustums 13 to separate. The first conical frustum 13 causes the corresponding pin 11 to slide out of the hexagonal prism 9, while the spring 12 is compressed. The protective plate 18 can provide protection for the gums.

[0027] A pair of insertion holes 19 are provided on the inner wall of the internal hexagonal connection hole 8. Each insertion hole 19 is adapted to the pin 11. The pin 11 is inserted into the corresponding insertion hole 19, so that the hexagonal prism 9 is connected and fixed in the internal hexagonal connection hole 8, preventing the protective plate 18 from shaking at will.

[0028] The artificial tooth root 1 has an external thread 20 on its outer periphery. The external thread 20 increases the contact area between the artificial tooth root 1 and the alveolar bone. The external thread 20 can be embedded in the alveolar bone tissue, just like a screw being screwed into wood, so that the artificial tooth root 1 is tightly integrated with the surrounding bone tissue, effectively preventing the artificial tooth root 1 from loosening or shifting during chewing, and providing stable support for the dental implant.

[0029] The base connecting part 2 is provided with an external thread 21 on its outer periphery, and an internal thread is provided on the inner wall of the connecting hole. The internal thread is adapted to the external thread 21, and the external thread 21 can be tightly screwed into the internal thread on the inner wall of the connecting hole, so that the base connecting part 2 and the artificial tooth root 1 are firmly connected.

[0030] The working principle of this utility model is as follows:

[0031] The artificial tooth root 1 can be surgically implanted into the alveolar bone. External thread 20 increases the contact area between the artificial tooth root 1 and the alveolar bone, allowing it to embed itself into the alveolar bone tissue, much like a screw being tightened into wood. This ensures a tight connection between the artificial tooth root 1 and the surrounding bone tissue, effectively preventing loosening or displacement during chewing and providing stable support for the implant. External thread 21 can tightly engage with the internal thread on the inner wall of the connecting hole, ensuring a stable connection between the abutment connection 2 and the artificial tooth root 1. The sealing frustum 3 can be embedded into the connecting part at the top of the artificial tooth root 1. The connection hole initially constructs a solid physical barrier, effectively preventing foreign objects such as bacteria and food debris from entering the oral cavity. The sealing ring 4 is squeezed by the inner wall of the connection hole at the top of the artificial tooth root 1. After being compressed, the sealing ring 4 perfectly fills the tiny gap between the sealing frustum 3 and the connection hole at the top of the artificial tooth root 1, greatly enhancing the sealing effect. The sealing disc 5 covers the top of the artificial tooth root 1. The neck of the abutment 6 can guide the growth of gingival tissue. The head of the abutment 7 protrudes from the gingival tissue, guiding the gingival tissue to form a good shape during the healing period, creating favorable conditions for the subsequent installation of the restorative abutment and crown.

[0032] In the initial state, spring 12 pushes the first conical frustum 13, causing the pin 11 to retract into the hexagonal prism 9, with the pair of conical frustums 13 abutting each other. During installation, the hexagonal prism 9 is inserted into the first hexagonal socket connection hole 8, and a special tool is inserted into the second hexagonal socket connection hole 17, causing the rotating block 16 to rotate. The rotating block 16 causes the threaded rod 14 to rotate and descend on the hexagonal prism 9. The threaded rod 14 causes the second conical frustum 15 to move together, and the second conical frustum 15 presses against the pair of first conical frustums 13, causing the pair of first conical frustums 13 to separate. The first conical frustum 13 causes the corresponding pin 11 to slide out of the hexagonal prism 9, and the pin 11 is inserted into the corresponding socket 19, so that the hexagonal prism 9 is connected and fixed in the first hexagonal socket connection hole 8, preventing the protective plate 18 from shaking at will. The protective plate 18 can provide protection for the sutured gums, prevent the tongue from touching the gums, reduce the risk of gum wound infection, and allow the gums to heal in a relatively stable and safe environment.

[0033] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
