Description

Technical Field

[0001] The utility model relates to the field of dental prostheses, in particular to a fixed denture. Background Art

[0002] Dentures are what people often call "false teeth", just like "false legs" and "false limbs" are called "artificial limbs". "Dentures" means teeth that fulfill "duties" for humans. In medicine, it is a general term for restorations made after partial or complete tooth loss in the upper and lower teeth. Dentures are divided into removable and fixed. Fixed dentures (commonly known as "fixed dentures") cannot be removed and put on by the patient himself, while removable dentures (commonly known as "removable dentures") can be easily removed and put on by the patient.

[0003] Currently, the installation of fixed dentures in dentistry is relatively complicated. For example, a fixed denture disclosed in the utility model patent with publication number CN209808599U has a high installation cost and is not convenient for rapid installation of the denture. Therefore, those skilled in the art have provided a fixed denture to solve the problems raised in the above background technology. Utility Model Content

[0007] As a further solution of the utility model: both left and right side surfaces of the denture body are fixedly connected with denture hoops, and both sides of the two denture hoops that are away from each other are fixedly connected with two adjacent tooth hoops.

[0008] As a further solution of the present invention: a retainer is fixedly connected to the inner top wall of the denture body, and the bottom end of the retainer is located inside the adhesive storage tank.

[0009] As a further solution of the utility model: a sealing gasket is fixedly connected to the outer surface of the top end of the conical mounting nail, and the sealing gasket is made of resin.

[0010] As a further solution of the utility model: a model mark is provided on the front side of the conical mounting nail, and the model mark is located in the upper middle part of the conical mounting nail.

[0011] As a further solution of the utility model: a clamping groove is provided on the upper surface of the conical tooth seat.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The fixed denture can realize screw installation and fixation of the conical tooth seat through the provided conical installation pins, installation screw grooves, installation screw seats and conical tooth seats, and can place resin adhesive inside the adhesive storage groove and flow it into the surface of the conical tooth seat through the provided adhesive storage grooves, leakage holes, clamping grooves and retainers, so as to realize the clamping and bonding placement of the denture body, and facilitate the rapid installation operation of the denture body.
