AI Technical Summary

Technical Problem

Existing invisible denture bases are prone to wear and breakage during long-term chewing, and their strength and wear resistance are not good. The bases do not fit well with the oral mucosa, causing food residue to become embedded and easily causing mucosal inflammation.

Method used

The denture base is connected to the denture body by threads, and the retention sleeve is connected to the retention post by threads. Combined with a nano-silver antibacterial coating, elastic rubber pad and silicone cushioning pad, it enhances retention stability and antibacterial properties, and improves the fit between the denture base and the oral mucosa.

Benefits of technology

It enhances the retention stability and antibacterial properties of dentures, improves wearing comfort, reduces the risk of oral infection, and extends the lifespan of dentures.

Abstract

This utility model discloses an invisible denture base, including a denture base, with a denture body fixedly connected to the upper side of the denture base. The denture body includes a denture groove, which is formed inside the denture body. A retention sleeve is fixedly connected to one side of the denture groove, and a retention post is threadedly connected to the inner cavity of the retention sleeve. The denture base is fixedly connected to the lower side of the retention post. This utility model, by setting the denture body, allows the retention sleeve inside the denture body to be placed outside the retention post when wearing the denture. Due to the threaded connection between the retention sleeve and the retention post, the denture body and denture base are tightly integrated into a single unit. By using a threaded retention component, the magnitude of the retention force can be changed by rotating and adjusting the threads, ensuring stable retention of the denture under different conditions. During daily use, the antibacterial coating continuously functions, reducing the adhesion and reproduction of bacteria on the denture surface, lowering the risk of oral infection, and providing a healthier oral environment for the wearer.
