AI Technical Summary

Technical Problem

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.

Method used

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.

Benefits of technology

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.
