The price in Korea is cheap.
The mainstream brands are AIDI(IDI) dental implants in the United States, Norbert in Sweden, ITI in Switzerland and Aochitai in South Korea.
AIDI(IDI) dental implant: The material is five-grade titanium, and its strength and toughness are much better than the traditional four-grade pure titanium. Its design concept is "to reduce the overall time of dental implant by retaining more patients' alveolar bone and increasing the initial stability of implants, and even to load implants immediately, thus reducing the number of operations and the pain of waiting". The success rate of AIDI dental implants is over 99%.
The platform is designed as a contraction type, which makes the growth of alveolar bone and soft tissue more in line with the biological structure. Alveolar bone can grow upward according to the inverted trapezoid of the platform to prevent gingival tissue from shrinking. ?
The asymmetric arrow thread design reduces the resistance during implantation and uses a smaller hole for implantation. Strengthen initial stability and realize immediate planting.
Micro-threads in the neck can help the implant to resist lateral force, which is beneficial to the initial stability of the implant.
The top locking design enables the patient's own bone tissue to grow into the implant and improves the strength of bone integration. Increase the life of the implant.
Maxillary sinus lifting design can help patients with low maxillary sinus floor avoid maxillary sinus lifting, which not only saves money but also avoids the pain of patients.
Nobel dental implant: The structure of Nobel dental implant is a typical embedded two-stage implant system, that is, after the first operation, the implant is implanted into the jaw and meets the mucosal incision, so that the implant can complete the osseointegration in a closed environment (the average maxilla is 6 months and the average mandible is 3 months), and then the second operation is performed to expose the implant and install the abutment. After the second operation 1-2 weeks, the impression can be used to start the repair system. This is a classic and successful planting system. The implant system of this system adopts grade 4 pure titanium with a purity of 99.75%. From the structural point of view, the surface of the implant is a fine thread undulating structure. Because of the fluctuation of the thread structure, its surface area increases the thread structure, which also makes it easier to screw into place during surgical implantation. The design of thread structure has undergone rigorous biomechanical analysis and testing, which naturally increases the surface area and distributes stress through the thread structure. Noble planting system is a classic planting system.
ITI Switzerland:
Since 1974, the system has been successfully applied and accumulated a large number of clinical documents. ITI can be said to be the representative of irrational two-stage implant system, which is exposed to the mouth after one operation and does not need to be covered after healing. Without secondary operation, the bone can be directly connected to the abutment to complete the repair after the bone integration is completed.
Machining grade 4 titanium. Made of commercial pure titanium (Grade 4 ISO5832/ 1). Compared with grade 3 titanium, the contents of oxygen and iron are increased. Its mechanical properties are improved. Due to the existence of titanium plasma coating (TPS), the bone contact area is increased. The surface of all ITI implants has a plasma coating of titanium paste containing micropores, and the surface roughness of the etched coating is 20 μm and the thickness is about 20-30 μm m.. The coating increases the surface area and the percentage of bone bonding, and obviously increases its anti-dislocation ability. Smooth machined neck. ITI's gingival-penetrating neck is cup-shaped and has a smooth machined surface, which is considered by designers to be beneficial to the attachment of neck soft tissue and prevent periodontal soft tissue infection.
South Korea Aochitai:
Aochitai implant system ranked first in Korea for many years, and obtained FDA and CE certification, and obtained SFDA III certification in June 2006.
The success rate of 1 and 5 years was 84% ~ 92% for maxilla and 9 1% ~ 99% for mandible.
2. The annual success rate of10 is 8 1% ~ 82% for maxilla and 89% ~ 98% for mandible;
3. The success rate of15 was 78% for maxilla and 86% for mandible.
It has been more than 30 years since it was first implanted, and its prostheses and implants are still functioning normally, so how long the implant can last remains to be studied.
