DETAILED DESCRIPTION

[0022] The technical scheme of the utility model will be further explained in detail in combination with the specific implementation:

[0023] Please refer to Figures 1-6The utility model provides an anti-bite force denture, including the base 2 of the denture, the bottom of base 2 is fixed with the threaded column 3 extending to the alveolus, the end of base 2 away from threaded column 3 is fixed with the butt joint pipe 5, butt joint pipe 5 is coaxial with threaded column 3, and the butt joint assembly is installed on butt joint pipe 5, and the end of butt joint assembly away from butt joint pipe 5 is fixed with artificial tooth body 1, and a plurality of bosses 7 are fixed and installed evenly on base 2, and the extension column 8 that butt joint is fixed with artificial tooth body 1 is fixed on boss 7.

[0024] When the implant of the utility model denture structure is carried out, threaded column 3 is rotated and embedded in the alveolus to be fixed, threaded column 3 plays the supporting role to base 2, artificial tooth body 1 is butt jointed with base 2 through butt joint assembly, and the installation of artificial tooth body 1 is completed.

[0025] Wherein, the bottom of artificial tooth body 1 is provided with a plurality of convex grooves 9 vertically corresponding with boss 7 and extension column 8.Ring-shaped sleeve 14 and conical sleeve 15 are fixed on extension column 8, and ring-shaped sleeve 14 and conical sleeve 15 are integrally formed.The material of ring-shaped sleeve 14 and conical sleeve 15 is flexible rubber.

[0026] In the process of butt joint of artificial tooth body 1 and base 2, boss 7 and extension column 8 are inserted into the vertically corresponding convex groove 9 and play the positioning effect of artificial tooth body 1, and ring-shaped sleeve 14 and conical sleeve 15 are embedded in convex groove 9, so that when artificial tooth body 1 is subjected to greater bite effect, ring-shaped sleeve 14 and conical sleeve 15 can play the good buffering and damping effect on artificial tooth body 1, greatly improving the stability of artificial tooth body 1 and the comfort of alveolus.

[0027] The butt joint assembly of the utility model includes the guide sleeve 11 fixed with artificial tooth body 1, the guide sleeve 11 is sleeved on butt joint pipe 5, the guide sleeve 11 is fixed with butt joint column 4, the butt joint column 4 is slidably extended into butt joint pipe 5, the side wall of butt joint column 4 is slidably installed with the abutting block 13 abutting with the inner wall of butt joint pipe 5, and the abutting block 13 is fixed with the push spring 16 between butt joint column 4.The butt joint assembly further includes the guide strip 12 fixed on the inner wall of guide sleeve 11, and the strip hole 6 is formed in butt joint pipe 5 and is slidably matched with guide strip 12.
