Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1: referring to fig. 1-4, a fixing denture comprises a retainer 1 and a bridge 3, wherein the retainer 1 is respectively arranged at two sides of the bridge 3, a connector 4 is arranged between the retainer 1 and the bridge 3, the retainer 1 and the bridge 3 are fixedly connected through the connector 4, two groups of jacks 7 are respectively arranged inside one side of the retainer 1 and inside two sides of the bridge 3, a support body 8 is inserted between the jack 7 inside one side of the retainer 1 and the jack 7 inside one side of the bridge 3, the upper surfaces of the retainer 1 and the bridge 3 are flush with each other, and the lower surface of the retainer 1 is lower than the lower surface of the bridge 3;

the support body 8 penetrates through the interior of the connecting body 4, and the support body 8 is completely hidden among the retainer 1, the bridge body 3 and the interior of the connecting body 4;
