AI Technical Summary
The connection between existing porcelain dental implants and the tooth structure is not stable enough, making them prone to breakage, which affects their lifespan and usability.
It employs stable components, including a first metal plate, a second metal plate, a connecting plate, a connecting rod, threads, grooves, slide bars, springs, and protrusions. The connection stability between the implant and the tooth is improved through threaded connections and sliding components, and it is equipped with a wear-resistant sleeve to enhance wear resistance and corrosion resistance.
It improves the connection stability between the implant and the tooth, prevents detachment, extends the service life, and enhances the wear resistance and corrosion resistance of the tooth, thus improving the practicality of porcelain crowns.
