[0030] The dental bed fixing body 2 comprises a base 21, an insertion slot 22 and a clamping slot 23, the base 21 is provided in a columnar structure, and an insertion slot 22 adapted to the clamping plate 56 and the clamping block 57 is arranged in the interior, and the clamping slots 23 adapted to the clamping block 57 are arranged on the inner surface of the insertion slot 22 near the bottom on both sides, which solves the problem that the existing removable denture is not stable enough during use and is easy to fall off, affecting the use experience of the patient.

[0031] In the embodiment, the top block 54 is in a trapezoidal structure with a narrow upper end and a wide lower end, and the left and right sides of the top block 54 are in contact with the inner sides of the two clamping plates 56, and the trapezoidal structure can fit the state of the two clamping plates 56 after being rotated, and the up-down movement of the top block 54 can drive the two clamping plates 56 to rotate relatively, thereby realizing the opening and closing of the clamping plates 56.

[0032] In the embodiment, the base 52 is fixedly provided with a sleeve 59 at the lower end, and the sleeve 59 is adapted to the size of the base 21, and the sleeve 59 allows the base 52 and the base 21 to be connected by sleeving, which can provide stable support and effectively prevent the connection from loosening.

[0033] In the embodiment, the rigid connecting wires 51 on the two sets of denture fixing bodies 5 are connected by the steel wire 4, and the steel wire 4 is in an arc structure and is attached to the back side of the incisors on the lower denture 1, and the steel wire 4 connects the rigid connecting wires 51 on the two sets of denture fixing bodies 5, which can form a stable overall structure of the two sets of denture fixing bodies 5, thereby enhancing the stability of the lower denture 1 in the oral cavity, and the steel wire 4 can simultaneously control the up-down movement of the rigid connecting wires 51 on both sides, thereby realizing the installation and disassembly of the denture fixing bodies 5 and improving the operation convenience.

[0034] In the embodiment, the groove teeth on the lower denture 1 where the denture fixing bodies 5 are installed are provided with grooves for accommodating the rigid connecting wires 51, and the grooves provide an accurate placement position for the rigid connecting wires 51, thereby ensuring the stability of the connecting wires during use of the denture and preventing displacement or falling off, and the grooves allow the rigid connecting wires 51 to move up and down in the lower denture 1.

[0035] In the embodiment, a horizontal limiting baffle 53 is fixedly arranged in the interior of the base 52, and the rigid connecting wires 51 are slidably connected through the limiting baffle 53, and the main purpose of the limiting baffle 53 is to limit the movement range of the rigid connecting wires 51 in the interior of the base 52. By arranging a fixed horizontal baffle, it can be ensured that the top block 54 will not exceed the predetermined range during up-down movement, thereby ensuring the stability and reliability of the denture fixing bodies 5.

[0036] In this embodiment, the abutment 21 is fixed at the bottom of the implant 24, and its surface is provided with threads. The tapered implant 24 is designed to better embed into the gum, forming a stable support point. The tapered structure helps to disperse pressure and increase the contact area between the implant 24 and the alveolar bone, thereby improving the stability of the denture. At the same time, the threads on the surface of the implant 24 increase the friction between the implant 24 and the gum, helping to firmly fix the implant 24 in the gum.

[0037] The working principle of the anti-loose removable denture is as follows:

[0038] First, the gum fixing body 2 is implanted into the patient's gum through the tapered implant 24 at the bottom, providing a support fixed point for the installation of the removable denture.

[0039] When installing the removable denture, the steel wire 4 behind the incisors is buckled and pulled upwards. The rigid connecting wire 51 on the denture fixing body 5 is moved upwards by the steel wire 4, and the top block 54 inside the post 52 is moved upwards by the rigid connecting wire 51. The top block 54 pushes the upper ends of the two clamping plates 56 to the sides during the movement, causing the lower ends of the two clamping plates 56 to close together. Then, the two clamping plates 56 are inserted into the insertion slot 22 inside the gum fixing body 2 until the clamping plates 56 contact the bottom of the insertion slot 22. Then, the steel wire 4 is released, and the internal spring force of the spring sheet 58 is released, pushing the lower ends of the two sets of clamping plates 56 outward, causing the clamping blocks 57 on the outside of the clamping plates 56 to be clamped into the clamping grooves 23 inside the insertion slot 22. The clamping plates 56 are stably connected to the abutment 21 through the clamping blocks 57, achieving quick installation of the removable denture. During this process, the two sets of clamping plates 56 are squeezed during the opening process, causing the top block 54 to move downward, causing the steel wire 4 to move downward and return to its original position;

[0040] During daily use, the clamping blocks 57 are tightly clamped in the clamping grooves 23, and the implant 24 is firmly fixed in the gum, so the lower denture 1 can remain stable and not easily fall off. The connection method of the rigid connecting wire 51 and the steel wire 4 also ensures that the denture can form a whole during use, resisting external forces and improving the stability of the denture. At the same time, the steel wire 4 can control the upward and downward movement of the two rigid connecting wires 51 on both sides, achieving the installation and removal of the denture fixing body 5, improving the operation convenience. The design of the limiting stopper 53 ensures the movement range of the rigid connecting wire 51 inside the post 52, preventing the clamping blocks 57 from being pulled out of the clamping grooves 23 due to excessive movement of the top block 54, thereby ensuring the stability of the denture;

[0041] When the denture needs to be disassembled, the steel wire 4 is only pulled upward, the rigid connecting wires 51 of the two sets of denture fixing bodies 5 are simultaneously moved upward, the upward movement of the rigid connecting wires 51 drives the top blocks 54 to move upward, a pushing force is generated on the clamping plates 56, the lower ends of the two clamping plates 56 are close to each other, the clamping blocks 57 are separated from the clamping grooves 23, then the denture fixing bodies 5 are separated from the gum fixing bodies 2, and the movable denture can be taken off.

[0042] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not a limitation on the embodiments of the utility model, and for ordinary skilled in the art, on the basis of the above description, other different forms of changes or variations can be made, all the embodiments cannot be exhausted here, and all the obvious changes or variations derived from the technical solutions of the utility model still fall within the protection scope of the utility model.
