AI Technical Summary

Technical Problem

In existing dental implant components, the screw connections between the abutment and the implant are prone to loosening due to multi-directional loads, leading to unstable connections and potentially fatigue fracture of the screw connections.

Method used

An abutment is installed in the mounting channel of the base, and the abutment is made to abut against the screw connection. The axial limiting effect is increased by the threaded engagement. At the same time, an abutment protrusion and a receiving groove are provided to enhance radial fixation. A self-locking mechanism is formed by using a thread design with opposite directions of rotation. Combined with the positioning structure, the connection stability is improved.

Benefits of technology

It effectively limits the loosening of the screw connectors, avoids gaps and shaking between the abutment and the implant, improves connection stability and reliability, reduces the risk of fatigue fracture of the screw connectors, and enhances the long-term reliability of the abutment and implant.

Abstract

This application relates to a dental implant assembly, specifically in the field of dental implant technology. The dental implant assembly includes an abutment, a screw connector, and an abutment. The abutment has an installation channel, and the screw connector is threaded through the installation channel to fix the abutment to the implant. The abutment is located in the installation channel and abuts against the screw connector to restrict the movement of the screw connector within the installation channel. By providing the abutment, an additional axial limiting effect can be added to the screw connector's own threaded locking, which helps to limit the axial movement of the screw connector within the installation channel, reducing the risk of loosening of the screw connector during long-term exposure to multi-directional chewing loads. This ensures that the screw connector maintains a stable locking state, which helps to avoid gaps and wobbling between the abutment and the implant, thereby reducing the possibility of fatigue fracture of the screw connector due to excessive bending stress. This improves the overall connection stability and long-term reliability of the dental implant assembly.
