[0002] Dentures are also known as "false teeth", which are the general term for prostheses made after partial or complete loss of upper and lower teeth in medicine. Removable dentures refer to false teeth that patients can remove and wear by themselves, and are suitable for most missing teeth in the whole mouth.

[0003] In people's daily life, due to the bumping and wearing of dentures during long-term use, local or single dentures often get damaged. When a denture needs to be replaced, only the entire upper and lower dentures can be replaced as a whole, and it is impossible to replace a single denture. If the entire upper and lower dentures are replaced as a whole, the cost is relatively high, causing an economic burden on patients.

Specific implementation mode

[0024] The following will cooperate with the drawings and embodiments to elaborate in detail on the implementation mode of the present application, so as to fully understand the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects and implement accordingly.

[0025] As Figures 1 - 7 shown, a detachable denture provided in this embodiment includes a denture base 1, a plurality of denture bodies 2 are fixedly installed on the denture base 1, mounting blocks 3 are fixedly installed at the bottoms of the denture bodies 2, a plurality of mounting grooves 4 adapted to the mounting blocks 3 are opened at the top of the denture base 1, clamping holes 5 are opened on both sides of the mounting blocks 3, arc-shaped clamping blocks 7 connected by elastic components 6 are arranged inside the clamping holes 5, and clamping grooves 8 adapted to the arc-shaped clamping blocks 7 are opened inside the mounting grooves 4.

[0026] Furthermore, as Figures 3 - 4 and Figure 7As described above, the elastic component 6 includes a telescopic rod 10 fixedly installed between the inner wall of the installation groove 4 and the arc-shaped clamping block 7, and a first spring 11 sleeved on the surface of the telescopic rod 10. The two ends of the first spring 11 are respectively connected to the inner wall of the installation groove 4 and one side of the arc-shaped clamping block 7. When it is necessary to replace the denture body 2, the denture body 2 can be pulled out upward. When the denture body 2 moves upward, it drives the arc-shaped clamping block 7 to move upward. When the arc-shaped clamping block 7 moves upward and is squeezed, the first spring 11 and the telescopic rod 10 are synchronously squeezed and contracted, so that the arc-shaped clamping block 7 will move towards the card hole 5 until it completely disengages from the inside of the card slot 8, thus completing the quick disassembly. Take a new denture body 2 and insert it downward through the installation block 3 and align it with the installation groove 4. When the arc-shaped clamping block 7 moves downward and is squeezed, the first spring 11 and the telescopic rod 10 are synchronously squeezed and contracted, so that the arc-shaped clamping block 7 contracts inward inside the card hole 5 until it fits with the card slot 8. Using the resilience of the first spring 11, the arc-shaped clamping block 7 rebounds into the inside of the card slot 8 to limit and fix the denture body 2 and the installation block 3, thus completing the quick installation. The telescopic rod 10 can prevent the first spring 11 from weakening in elasticity and bending during long-term use. When a single denture body 2 is damaged due to long-term use and bumping, each denture body 2 can be disassembled separately, and there is no need to replace all the denture bodies 2 of the entire upper and lower jaws, thereby reducing the maintenance cost and alleviating the economic burden on patients.

[0027] A limiting mechanism 9 for fixing the arc-shaped clamping block 7 is arranged inside the denture base 1.

[0028] Furthermore, as Figures 1 - 7 shown, the limiting mechanism 9 includes a cavity 12 opened inside the denture base 1, an arc-shaped support plate 13 movably installed inside the cavity 12, a plurality of second springs 14 fixedly installed between the arc-shaped support plate 13 and the inner wall of the cavity 12, and a plurality of insertion rods 15 symmetrically installed on the top of the arc-shaped support plate 13. A limiting hole 16 penetrating into the inside of the cavity 12 is opened on the arc-shaped clamping block 7, and the insertion rods 15 are adapted to the size of the limiting hole 16. Two sliding rods 17 are symmetrically installed on the top of the arc-shaped support plate 13, and one end of the sliding rod 17 movably penetrates through the outer surface of the denture base 1. By pressing the sliding rod 17, it can move downward, thereby driving the arc-shaped support plate 13 to move downward and squeezing the second spring 14 to contract. When the arc-shaped support plate 13 moves downward, it drives the insertion rods 15 to move downward until they disengage from the inside of the limiting hole 16 and no longer limit and fix the arc-shaped clamping block 7, facilitating the upward extraction of the denture body 2 for replacement. After replacing the new denture body 2, release the sliding rod 17. Using the resilience of the second spring 14, the second spring 14 drives the arc-shaped support plate 13 to move upward, so that the insertion rods 15 move upward and re-insert into the inside of the limiting hole 16 to limit and fix the arc-shaped clamping block 7, and further fix the denture body 2 to make it more stable, preventing the denture body 2 from loosening and falling off during long-term use.

[0029] In further, Figures 1 - 3 As shown, a plurality of sealing rings 18 are fixedly installed on the upper surface of the denture base 1, and the sealing rings 18 are sleeved on the surface of the sliding rod 17; by setting the sealing rings 18, the sealing between the sliding rod 17 and the denture base 1 can be improved to prevent the patient's saliva from entering the interior of the denture base 1 during use and causing bacterial growth.

[0030] Furthermore, Figures 2 - 6 As shown, a plurality of support rods 21 are fixedly installed inside the cavity 12, and an arc-shaped support plate 13 is movably sleeved on the surface of the support rod 21. A rubber protective layer 19 is installed at the bottom of the denture base 1, and the rubber protective layer 19 is connected to the denture base 1 by a bolt 20; the arc-shaped support plate 13 may shake or be unstable when squeezing the second spring 14. By setting the support rod 21, the stability of the arc-shaped support plate 13 when moving up and down can be improved. By setting the rubber protective layer 19, when the patient wears the denture base 1, the rubber protective layer 19 contacts the patient's gums, thereby improving the wearing comfort. When the rubber protective layer 19 is damaged, each bolt 20 is turned to continuously move outward from the inside of the denture base body 1 under the action of the thread to complete the quick disassembly. When installing, take a new rubber protective layer 19 and turn the bolt 20 again. Under the action of the thread, the bolt 20 continuously moves inward to the inside of the denture base body 1, and the rubber protective layer 19 is limited and fixed to complete the quick replacement.

[0031] like Figures 1 - 7 As shown, the principle of the partially detachable denture provided in this embodiment is as follows: when the denture body 2 needs to be replaced, the denture body 2 can be pulled out upwards, and the arc-shaped clamping block 7 is driven to move upwards when the denture body 2 moves upwards. When the arc-shaped clamping block 7 moves upwards and is squeezed, the first spring 11 and the telescopic rod 10 are synchronously squeezed to contract, so that the arc-shaped clamping block 7 moves toward the clamping hole 5 until it is completely out of the clamping slot 8, thereby completing the quick disassembly, and a new denture body 2 is taken and inserted downwards through the mounting block 3 to align with the mounting slot 4. When the arc-shaped clamping block 7 moves downwards and is squeezed, the first spring 11 and the telescopic rod 10 are synchronously squeezed to contract, so that the arc-shaped clamping block 7 moves toward the clamping hole 5 until it is completely out of the clamping slot 8, thereby completing the quick disassembly, and a new denture body 2 is taken and inserted downwards through the mounting block 3 to align with the mounting slot 4. The retracting rod 10 retracts so that the arc-shaped clamping block 7 retracts inwardly inside the clamping hole 5 until it fits with the clamping slot 8. Utilizing the resilience of the first spring 11, the arc-shaped clamping block 7 rebounds to the inside of the clamping slot 8 to limit and fix the denture body 2 and the mounting block 3, thereby completing quick installation. The telescopic rod 10 can prevent the first spring 11 from weakening and bending after long-term use. When a single denture body 2 is damaged by bumps and collisions due to long-term use, each denture body 2 can be disassembled separately without replacing the entire denture body 2 of the upper and lower jaws, thereby reducing maintenance costs and alleviating the economic burden on patients.
