[0002] Dentures, also known as false teeth, are devices that restore the shape and function of missing teeth. Traditional dentures include removable dentures and fixed dentures. Removable dentures are composed of bases, clasps, and resin teeth. They can be removed and worn for easy cleaning. Fixed dentures require tooth preparation of the adjacent teeth on both sides of the missing teeth, and are bonded to the abutment teeth after production. Implant dentures are made by preparing a hole in the jawbone where the missing teeth are located, placing an implant, forming bone healing, and making a crown connected to the implant to perform the chewing function.

[0003] The patent with the authorization announcement number CN215228667U discloses a full-ceramic denture that prevents accidental loosening, including a first fixing frame, a fixing seat and a base, wherein the first fixing frame is fixedly installed on one side of the base, a first limiting frame is movably installed on the inner side of the first fixing frame, and a second fixing frame is fixedly installed on the other side of the base. The utility model provides limiting blocks on both sides of the first limiting frame and the second limiting frame, which can be engaged between the gaps of natural teeth through the limiting blocks, so that the first limiting frame and the second limiting frame are not easy to fall off, and the stability is effectively improved. However, the utility model only fixes the denture body by screws, which may fall off after long-term use, and after falling off, it is necessary to go to the hospital to install it with special tools, which is very troublesome.
