AI Technical Summary
After a long period of use, due to unbalanced stress during chewing, cracks are prone to the connection between the implant and the base, which eventually leads to the denture breakage, affecting the service life.
A semi-solid defined tooth repair mechanism is designed to prevent cracks from occurring by setting an elastic sheet in the groove of the base and using the magnetic attraction between the ball head and the elastic sheet to form a stable connection to buffer the deformation and displacement of the base during chewing.
Effectively prevent dentures from breaking due to stress imbalance during long-term use, improve the service life of dentures, and reduce the risk of cracking and failure when multiple implants are fixed.

When in use, the base 1 is buckled on the gums, the groove 5 on the base 1 corresponds to the ball head 4, the ball head 4 corresponds to the elastic sheet 6 on the base 1, and they are attracted to each other by magnetic force. The implant 3 is fixed to the human gums, and the ball head 4 on the implant 3 is therefore firmly fixed, and the base 1 is fixed by the attraction between the ball head 4 and the elastic sheet 6. When chewing, if the base 1 is deformed or displaced by force, the elastic sheet 6 can be buffered, thereby avoiding crack failure of the base 1. The base 1 of the utility model can be fixed on the gums through a plurality of implants 3, and is not prone to cracking and other faults after long-term use.
[0022] Specifically, the elastic sheet 6 or the ball head 4 is embedded with a magnet or made of a magnetic material, so as to ensure that the elastic sheet 6 or the ball head 4 has stable magnetism.
