Cylindrical implant and system
By designing a cylindrical implant without threads, and utilizing a groove to form a flap structure and a double-threaded locking connection, the problems of insufficient initial stability and screw loosening of threaded implants are solved, achieving high initial stability and long-term reliability of the implant.

AI Technical Summary
Existing dental implants suffer from insufficient initial stability due to their threaded design, resulting in loose screw connections and concentrated chewing stress on the alveolar ridge, causing bone resorption and implant loosening and detachment.
A cylindrical implant without threads is designed. A flap structure is formed by setting a groove on the outer wall of the implant. The elastic flap enhances the initial stability. A double threaded locking connection structure is adopted, combined with differential pitch anti-loosening design and necking section elastic pre-tightening mechanism to improve connection reliability.
It significantly improves the initial stability and long-term success rate of implants, reduces the risk of screw loosening, simplifies surgical procedures, enhances bio-sealing performance, and is suitable for implant restorations in different tooth positions.
