Description

Technical Field

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

[0002] Dental implants are key components in modern oral restoration, often referred to as the "foundation" of artificial teeth. They are typically made of biocompatible materials, such as pure titanium or titanium alloys. These materials can integrate with the alveolar bone, providing stable support for subsequent tooth restoration. During implant surgery, the dentist prepares a suitable implant socket in the alveolar bone and precisely inserts the implant into it. Over time, the implant and alveolar bone gradually fuse, forming a stable osseointegration. At this point, the implant can assume the chewing function of the tooth. The dental implant abutment is an important component connecting the implant to the superstructure, acting like a bridge and playing a crucial role. It is divided into healing abutments and permanent abutments. The function of the healing abutment is to guide the growth of gingival tissue around the implant, forming a healthy gingival cuff, creating favorable conditions for the subsequent installation of the permanent abutment and crown. The permanent abutment is directly connected to the final crown.

[0003] Existing dental implant abutments have the following shortcomings: They are cumbersome to use. Dental implant abutments are divided into healing abutments and permanent abutments. In the early stages of dental implant surgery, the healing abutment needs to be installed on the implant. After the gums have healed, the dentist needs to carefully remove the healing abutment and then precisely install the permanent abutment. The implant is located on the alveolar bone. The whole process is not only time-consuming and increases the patient's pain, but also requires a high level of skill from the dentist and a suitable surgical environment. A slight mistake may lead to implant restoration failure, bringing a double burden of economic and physical stress to the patient. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a dental implant composite abutment assembly, which solves the problem that the existing dental implant abutments are relatively troublesome to use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dental implant composite abutment assembly, including a connecting post, a cone fixedly connected to the top of the connecting post, an abutment fixedly connected to the top of the cone, a sealing cone ring, a sterilizing ring, and a connecting frustum fixedly connected to the top of the abutment, a threaded hole being provided on the top of the connecting frustum, a connecting bolt being threaded into the threaded hole, a healing cover being provided on the top of the sealing cone ring, a through hole being provided on the healing cover, and the through hole being adapted to the connecting bolt.

[0006] As a further embodiment of this utility model: the outer periphery of the connecting post is provided with external threads, and the bottom of the connecting post is provided with a semi-circular block.

[0007] As a further embodiment of this utility model: the top of the connecting bolt is provided with an internal hexagonal connecting hole.

[0008] As a further embodiment of this utility model: the top of the healing cover is provided with an annular groove, and a sealing ring is provided in the annular groove.

[0009] As a further embodiment of this invention: the top of the sterilization ring is provided with a sterilization coating.

[0010] As a further aspect of this invention, the antibacterial coating is made of nano-silver material.

[0011] As a further embodiment of this invention: the outer wall of the sterilization ring is fixedly connected to the sealing cone ring.

[0012] As a further embodiment of this invention: the inner wall of the sterilization ring is fixedly connected to the connecting frustum.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model is equipped with an abutment, a sealing cone ring, a connecting frustum, a connecting bolt, and a healing cover. The sealing cone rings at the bottom of the healing cover and the top of the abutment fit together, effectively isolating external bacteria and other contaminants. The connecting bolt connects the healing cover and the abutment together through the connecting frustum, so that the healing cover and the abutment can be used as a healing abutment. After the gums heal, the healing cover can be removed, and the abutment alone can be seamlessly converted into a permanent abutment. This greatly simplifies the cumbersome steps of removing the healing abutment and installing the permanent abutment in the traditional implant procedure, reduces the doctor's operation time and difficulty, and at the same time, the patient does not have to experience the pain and discomfort caused by a second complicated operation.

[0015] 2. This invention features a sterilization ring with a sterilization coating that continuously exerts its sterilization effect. The coating is made of nano-silver material, which possesses strong broad-spectrum antibacterial capabilities, effectively inhibiting the growth and reproduction of various bacteria, fungi, and viruses. The nano-silver sterilization coating actively releases silver ions over a prolonged period, disrupting the cell membrane structure of bacteria and interfering with their metabolic activities, thus preventing bacteria from accumulating in the implant area at the source. When using the healing cap, it effectively kills bacteria attempting to invade the implant area in the oral cavity. After the crown is installed, it prevents bacteria from growing and multiplying in the gap between the crown and abutment, reducing the probability of inflammation, helping to extend the lifespan of the implant restoration, improving the overall implant treatment effect, and providing patients with a longer and more reliable dental implant experience.

[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 dental implant composite abutment assembly includes a connecting post 1, a cone 2 fixedly connected to the top of the connecting post 1, an abutment 3 fixedly connected to the top of the cone 2, a sealing cone ring 4, a sterilizing ring 5, and a connecting frustum 6 fixedly connected to the top of the abutment 3, a threaded hole 7 on the top of the connecting frustum 6, and a connecting bolt 8 threadedly connected to the threaded hole 7. A healing cover 9 is provided on the top of the sealing cone ring 4, and a through hole is provided on the healing cover 9, which is adapted to the connecting bolt 8. In the early stage of dental implant surgery, the connecting post 1 is first installed on the implant. The bottom of the healing cover 9 fits against the sealing cone ring 4 on the top of the abutment 3, effectively isolating external bacteria and other contaminants. The connecting bolt 8 passes through the through hole on the healing cover 9 and is then tightened into the threaded hole 7 on the top of the connecting frustum 6, connecting the healing cover 9 and the abutment 3 together. Together, they can be used as a healing abutment. After the gums have healed, the connecting bolt 8 is unscrewed from the threaded hole 7 at the top of the connecting frustum 6, and the healing cover 9 is removed. The abutment 3 can then be seamlessly converted into a permanent abutment. This greatly simplifies the cumbersome steps of removing the healing abutment and installing the permanent abutment in the traditional implant procedure, reducing the doctor's operation time and difficulty. At the same time, patients do not have to experience the pain and discomfort caused by a second complex operation. The sterilization ring 5 can continuously exert a sterilization effect. When using the healing cover 9, it can effectively kill bacteria in the oral cavity that attempt to invade the implant area. After the crown is installed on the abutment 3, it can prevent bacteria from growing and multiplying in the gap between the crown and the abutment 3, reduce the probability of inflammation, help extend the life of the implant restoration, improve the overall implant treatment effect, and give patients a longer and more reliable dental implant experience.

[0025] The connecting post 1 has an external thread 10 on its outer periphery and a semi-circular block 11 at its bottom. The external thread 10 on the outer periphery of the connecting post 1 is precisely matched with the internal thread of the implant. After being tightly screwed together, it greatly enhances the stability of the connection between the implant and the superstructure. During daily chewing, complex and diverse stresses are generated in the oral cavity, including vertical biting force, lateral shear force, and torsional force. The external thread 10 fits tightly with the internal thread of the implant, which can effectively disperse these complex stresses, avoid stress concentration that could damage the implant, greatly reduce the risk of implant loosening, and ensure the long-term stable operation of the implant restoration. This allows patients to chew various foods normally with peace of mind. During the implant surgery installation process, the doctor needs to accurately insert the connecting post 1 into the internal thread hole of the implant. The unique shape of the semi-circular block 11 can act like a navigation system to help the connecting post 1 quickly and accurately align with the internal thread hole, greatly saving installation time and improving surgical efficiency.

[0026] The top of the connecting bolt 8 has an internal hexagonal connection hole 12. Doctors can use an internal hexagonal wrench to insert into the internal hexagonal connection hole 12 to apply force precisely and achieve accurate control of the torque of the connecting bolt 8.

[0027] The top of the healing cover 9 has an annular groove, and a sealing ring 13 is placed in the annular groove. After the connecting bolt 8 is tightened, the nut squeezes the sealing ring 13, and the sealing ring 13 fits tightly with the nut. This prevents bacteria, food debris, saliva and other contaminants in the oral cavity from entering the healing cover 9 through the through hole on the healing cover 9. This creates a clean and sterile healing microenvironment for the tissues around the implant. This not only reduces the risk of infection and ensures the stability of the implant, but also promotes healthy healing of the gingival tissue, laying a solid foundation for the subsequent installation of the crown and long-term use, and greatly improving the success rate and service life of implant restoration.

[0028] The top of the sterilization ring 5 is provided with a sterilization coating 14. The sterilization coating 14 is made of nano-silver material. Nano-silver material has a strong broad-spectrum antibacterial ability and can effectively inhibit the growth and reproduction of various bacteria, fungi and viruses. The nano-silver sterilization coating 14 can actively attack and continuously release silver ions for a long time, destroy the cell membrane structure of bacteria and interfere with their metabolic activities, thus preventing bacteria from accumulating in the planting area from the root.

[0029] The outer wall of the sterilization ring 5 is fixedly connected to the sealing cone ring 4, and the inner wall of the sterilization ring 5 is fixedly connected to the connecting truncated cone 6. This can protect the planting area in all directions. From the edge of the implant to the inside of the abutment 3, bacteria are difficult to grow, which greatly improves the cleanliness of the environment around the implant and ensures the stability and long-term use of the implant.

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

[0031] In the initial stage of dental implant surgery, the connecting post 1 is first installed on the implant. The external thread 10 on the outer periphery of the connecting post 1 is precisely matched with the internal thread of the implant. After tight engagement, it greatly enhances the stability of the connection between the implant and the superstructure. During daily chewing, complex and diverse stresses are generated in the oral cavity, including vertical biting force, lateral shear force, and torsional force. The tight fit between the external thread 10 and the internal thread of the implant can effectively disperse these complex stresses, avoid stress concentration that could damage the implant, greatly reduce the risk of implant loosening, ensure the long-term stable operation of the implant restoration, and allow patients to chew various foods with peace of mind. During the implant installation stage, the doctor needs to accurately insert the connecting post 1 into the internal thread hole of the implant. The unique shape of the semi-circular block 11 can act like a navigation system to help the connecting post 1 quickly and accurately align with the internal thread hole, greatly saving installation time and improving surgical efficiency.

[0032] The sealing cone ring 4 at the bottom of the healing cover 9 and the top of the base 3 fit together, effectively isolating external bacteria and other contaminants. The connecting bolt 8 passes through the through hole on the healing cover 9. The doctor can use an Allen wrench inserted into the Allen connection hole 12 to precisely apply force, achieving precise control of the torque of the connecting bolt 8. This allows the connecting bolt 8 to be tightened into the threaded hole 7 at the top of the connecting frustum 6, connecting the healing cover 9 and the base 3 together. This allows the healing cover 9 and the base 3 to be used as a healing base. After the connecting bolt 8 is tightened, the nut compresses the sealing ring 13, and the sealing ring 13 fits tightly with the nut, preventing bacteria, food debris, saliva, and other contaminants in the oral cavity from entering through the through hole on the healing cover 9. The healing cap 9 creates a clean and sterile healing microenvironment for the tissues surrounding the implant. This not only reduces the risk of infection and ensures the stability of the implant, but also promotes healthy healing of the gingival tissue, laying a solid foundation for subsequent crown installation and long-term use. This greatly improves the success rate and lifespan of implant restoration. After the gingiva has healed, the connecting bolt 8 is unscrewed from the threaded hole 7 at the top of the connecting frustum 6, and the healing cap 9 is removed. The abutment 3 can then be seamlessly converted into a permanent abutment. This greatly simplifies the cumbersome steps of removing the healing abutment and installing the permanent abutment in the traditional implant procedure, reducing the doctor's operation time and difficulty. At the same time, the patient does not have to experience the pain and discomfort caused by a second complex operation.

[0033] The sterilization ring 5 can continuously exert a sterilization effect. The nano-silver material has a strong broad-spectrum antibacterial ability, which can effectively inhibit the growth and reproduction of various bacteria, fungi and viruses. The nano-silver sterilization coating 14 can actively attack and continuously release silver ions for a long time, destroying the cell membrane structure of bacteria and interfering with their metabolic activities, thus preventing bacteria from accumulating in the implant area from the root. When using the healing cover 9, it can effectively kill bacteria in the oral cavity that attempt to invade the implant area. After the crown is installed on the abutment 3, it can prevent bacteria from growing and multiplying in the gap between the crown and the abutment 3, reduce the probability of inflammation, help extend the service life of the implant restoration, improve the overall implant treatment effect, and give patients a longer and more reliable dental implant experience.

[0034] 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.
