[0019] In order to more clearly understand the above purpose, features and advantages of the utility model, the utility model is further explained below by combining with the drawings and examples. It should be explained that the embodiment of the application and the features in the embodiment can be combined mutually without conflict.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] like Figures 1-5 As shown, a denture with anti-dislodgement function includes a denture body 1, an implant 2, and an abutment 8. The bottom of the denture body 1 is fixedly connected to a rotating seat 3 that is rotatably connected to the abutment 8. A support rod 9 is rotatably connected to the middle of one end of the implant 2. The support rod 9 is used to thread into the bottom end of the abutment 8. A spring rod 13 is fixedly installed inside the implant 2. The telescopic end of the spring rod 13 abuts against the support rod 9. A toothed ring 10 is fixedly connected to the outside of the support rod 9. An external gear 14 that meshes with the toothed ring 10 is rotatably connected to the edge of one end of the implant 2. A baffle 4 for blocking the external gear 14 is provided on the side of one end of the implant 2. A tooth 15 for meshing with the external gear 14 is provided on the inner side of the baffle 4.

[0022] In this technical solution, a rotating seat 3 is provided for the rotatable installation of the abutment 8 and the denture body 1. A support rod 9 is provided so that when the abutment 8 is inserted into the implant 2, the abutment 8 is rotated, causing the bottom of the abutment 8 to be helically inserted into the support rod 9. A spring rod 13 is provided so that when the support rod 9 is helically inserted into the abutment 8, the telescopic end of the spring rod 13 abuts against the support rod 9, making it difficult for the support rod 9 to rotate. That is, when the abutment 8 is not fully inserted into the support rod 9, the rotation of the abutment 8 will not cause the support rod 9 to rotate. An external gear 14 is provided and fixed to the outside of the support rod 9. The operator rotates the external gear 14, causing the gear ring 10 located outside the support rod 9 to rotate, which in turn causes the base 8 to rotate. A baffle 4 is provided to surround the external gear 14 to prevent it from being exposed and rotating accidentally. A tooth 15 is provided so that after the external gear 14 is rotated to fix the denture body 1 onto the implant 2, the baffle 4 is installed and the tooth 15 on the inner side of the baffle 4 meshes with the external gear 14. When the baffle 4 does not move, the external gear 14 cannot rotate, thus keeping the denture body 1 always fixed to the implant 2.

[0023] like Figure 2 As shown, a toothed ring 10 is also fixedly connected to the bottom end of the support rod 9. A threaded rod 7 is rotatably connected inside the implant 2. A gear 11 that meshes with the toothed ring 10 located at the bottom end of the support rod 9 is fixedly connected to the bottom of the threaded rod 7. A threaded sleeve 12 is threadedly connected to the top of the threaded rod 7. The threaded sleeve 12 is slidably installed with the implant 2 and is used to abut against the rotating seat 3.

[0024] In this technical solution, by setting a toothed ring 10, after the base 8 and the support rod 9 are screwed together to the extreme point, that is, the end face of the support rod 9 contacts the base 8, the base 8 rotates again. Through the action of the thread, the support rod 9 will be driven to break through the abutting friction of the spring rod 13 and rotate together with the base 8. The rotation of the support rod 9 drives the toothed ring 10 located at the bottom of the support rod 9 to rotate, which in turn drives the gear 11 to rotate. The rotation of the gear 11 drives the threaded rod 7 to rotate, which in turn drives the threaded sleeve 12 to slide. By setting the threaded sleeve 12, when the threaded sleeve 12 slides towards the denture body 1, it will abut against the rotating seat 3, thereby fixing the denture body 1 and the implant 2.

[0025] like Figure 2 As shown, there are multiple threaded rods 7, and these multiple threaded rods 7 are evenly arranged around the support rod 9.

[0026] In this technical solution, by setting multiple threaded rods 7 and thus adding multiple threaded sleeves 12, the contact area between the threaded sleeves 12 and the rotating seat 3 is increased, making it less likely for the denture to slip after it is fixed.

[0027] like Figure 5 As shown, a connecting plate 5 is provided at the connection between the baffle 4 and the implant 2. Two bolts 6 are fitted on the connecting plate 5, and the two bolts 6 are threadedly connected to the implant 2 and the baffle 4 respectively.

[0028] In this technical solution, a connecting plate 5 and a bolt 6 are used to fix the baffle 4 and the implant 2 to the connecting plate 5 respectively, thereby fixing the baffle 4 to the implant 2.

[0029] Working principle: During denture installation, the implant 2 is first fixed to the alveolar bone. Then, the abutment 8 and support rod 9 are inserted. During this insertion, the external gear 14 rotates, causing the abutment 8 to rotate and the bottom of the abutment 8 to helically engage with the support rod 9. Once the abutment 8 and support rod 9 are fully engaged, with the end face of the support rod 9 contacting the abutment 8, the abutment 8 rotates again. Through the action of the threads, the support rod 9 overcomes the frictional force of the spring rod 13 and rotates along with the abutment 8. The toothed ring 10 is rotated, which in turn drives the gear 11 to rotate. The rotation of the gear 11 drives the threaded rod 7 to rotate, which in turn drives the threaded sleeve 12 to slide. When the threaded sleeve 12 slides towards the denture body 1, it abuts against the rotating seat 3, fixing the rotating seat 3 to the implant 2, thereby fixing the denture body 1 to the implant 2. Then, the baffle 4 is placed, and the teeth 15 on the inner side of the baffle 4 mesh with the external gear 14. The two bolts 6 on the connecting plate 5 are then threadedly connected to the implant 2 and the baffle 4 respectively, thereby fixing the baffle 4 to the implant 2.

[0030] In addition, since the denture body 1 is designed to fit the gap between the teeth on both sides, it is often made into an irregular shape. Existing denture bodies 1 usually require rotation during installation, which requires the teeth on both sides to allow space for the irregular denture body 1 to rotate. This also causes the irregular denture body 1 to not fit completely with the teeth on both sides. In this technical solution, when installing the irregular denture body 1, only the abutment 8 needs to be rotated, and the denture body 1 does not need to rotate. The denture body 1 will only move downward and embed into the gap between the teeth on both sides.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
