[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The denture base can be connected to the mounting hole opened in advance in the alveolar bone through the threaded structure on its outer surface through the provided implant, so as to facilitate the subsequent installation of the denture base. The provided central screw can be connected to the denture base in conjunction with the screw hole opened in the implant, so that the denture base can be installed, thereby ensuring the stability of the connection between the denture base and the implant, and at the same time, the denture base can be conveniently disassembled for inspection, cleaning and maintenance in the future.

[0019] 2. The denture base, through the provided clamping block, has an inclined surface at its upper end, so when the toggle plate is moved downward, the first movable plate will be driven to move downward, and at the same time, the two T-shaped sliders will slide downward in the T-shaped groove. When the first movable plate moves downward, it will drive the rectangular connecting tube to move downward. After the rectangular connecting tube moves downward so that the clamping assembly and the clamping block contact with the inner cavity of the rectangular connecting tube, the clamping block will retract into the inner cavity of the clamping assembly, and at the same time, it will drive the limit plate to push the two second movable plates to move, thereby compressing the multiple second springs. When the clamping assembly completely enters the inner cavity of the rectangular connecting tube and the clamping block moves to the first rectangular through groove, The second spring force will push the second movable plate and the limiting plate to drive the clamping block to bounce to the front end, so that the clamping block can pop out from the first rectangular through groove on the surface of the rectangular connecting tube. At this time, the connection between the rectangular connecting tube and the clamping assembly can be completed. At the same time, the first spring can be set to pull the first connecting plate, the first movable plate and the rectangular connecting tube to move upward after the connection between the rectangular connecting tube and the clamping assembly is completed. Since the clamping block is a trapezoidal structure, when the rectangular connecting tube moves upward, the clamping block and the first rectangular through groove on the surface of the rectangular connecting tube will be clamped more tightly, thereby further ensuring the stability of the installation of the denture crown.

[0020] 3. When the denture crown needs to be disassembled, pressing the toggle plate downward will drive the first movable plate and the rectangular connecting tube to move downward. At this time, the clamping assembly will continue to move deep into the inner cavity of the rectangular connecting tube. At the same time, under the action of the triangular fixing block, the clamping block will be retracted to the deep inside of the clamping assembly again. When the clamping block is fully retracted into the clamping assembly, the magnetic plate will be magnetically connected to the magnetic block. At this time, the clamping block will be magnetically fixed in the clamping assembly. Then the toggle plate is released and the denture crown is pulled upward. Since the clamping block is magnetically fixed in the clamping assembly, when the denture crown is pulled upward to move the rectangular connecting tube, the clamping block will not be ejected from the first rectangular through groove opened at the front end of the rectangular connecting tube. At this time, the denture crown can be directly removed to complete its disassembly.

[0021] 4. The denture base can cancel the magnetic fixation of the clamping block by the third connecting plate when the denture crown needs to be installed later, so that the clamping block can be ejected from the clamping assembly to avoid the clamping block being continuously in the inner cavity of the clamping assembly under the magnetic connection between the magnetic plate and the magnetic block, affecting the subsequent installation and fixation of the denture crown. When in use, the third connecting plate is pressed down so that the movable rod drives the two rectangular sliding blocks to slide downward on the outer surface of the fixed rod. Here, since the two ends of the movable rod are movably connected with the two rectangular sliding blocks, the inclination angle of the movable rod can be adjusted. After adjusting to a suitable angle, the third connecting plate is pressed down to insert it between the magnetic plate and the magnetic block, and then the third connecting plate is bent to adjust the angle so that the magnetic plate is separated from the magnetic block. At this time, under the action of the second spring force, the second movable plate and the limit plate will be pushed to drive the clamping block to move forward, and the clamping block will extend out of the limit groove on the surface of the clamping assembly. Then the denture crown can be installed again, which has high practicality. BRIEF DESCRIPTION OF THE DRAWINGS

The central screw 9 that is set can cooperate with the screw hole 5 opened in the implant 3 to connect the denture base 1, so that the denture base 1 can be installed, thereby ensuring the stability of the connection between the denture base 1 and the implant 3, and at the same time, the denture base 1 can be conveniently disassembled for inspection, cleaning and maintenance in the future.

[0035] Embodiment 2, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Fig. 9As shown, a denture base is provided, and rectangular grooves 11 are symmetrically provided on the front and rear end surfaces of the denture crown 2, and through grooves 12 are provided at the lower ends of the two rectangular grooves 11, and rectangular sealing blocks 13 are detachably embedded in the two through grooves 12, and two T-shaped grooves 14 are symmetrically provided on both sides of the rectangular groove 11, and two groups of first fixing plates 15 are bonded to the top of the rectangular groove 11, and the lower ends of the two groups of first fixing plates 15 are detachably connected to first springs 16, and the lower ends of the first springs 16 are detachably connected to first connecting plates 17, and the lower ends of the first connecting plates 17 are welded to first movable plates 18, and T-shaped sliders 19 are symmetrically welded on both sides of the first movable plate 18, and the T-shaped sliders 19 are connected to the T The first movable plate 18 is slidably connected in the groove 14, a toggle plate 20 is welded to the front end of the first movable plate 18, a rectangular connecting tube 21 is welded to the lower end of the first movable plate 18, a first rectangular through groove 22 is provided at the front end of the rectangular connecting tube 21, two groups of second fixed plates 32 are symmetrically welded to the inner surface of the rear end of the clamping assembly 25, the front ends of the two groups of second fixed plates 32 are both detachably connected to the telescopic rod 33, the outer surface of the telescopic rod 33 is movably sleeved with a second spring 34, the front end of the telescopic rod 33 is detachably connected to the second movable plate 35, the clamping assembly 25 is movably connected to a limit plate 36, the front end of the limit plate 36 is welded with a clamping block 37, and the front end surface of the clamping assembly 25 is provided with a limit groove 38.

[0036] By setting the clamping block 37, since its upper end is an inclined surface, when the toggle plate 20 is moved downward, the first movable plate 18 will be driven to move downward, and at the same time, the two T-shaped sliders 19 will slide downward in the T-shaped groove 14. When the first movable plate 18 moves downward, it will drive the rectangular connecting tube 21 to move downward. After the rectangular connecting tube 21 moves downward so that the clamping assembly 25 and the clamping block 37 are in contact with the inner cavity of the rectangular connecting tube 21, the clamping block 37 will retract into the inner cavity of the clamping assembly 25, and at the same time, it will drive the limiting plate 36 to push the two second movable plates 35 to move, thereby compressing the multiple second springs 34. When the clamping assembly 25 completely enters the inner cavity of the rectangular connecting tube 21 and the clamping block 37 moves to the first rectangular through groove 22, the second spring 3 Under the action of the elastic force, the second movable plate 35 and the limiting plate 36 are pushed to drive the clamping block 37 to bounce to the front end, so that the clamping block 37 can pop out from the first rectangular through groove 22 opened on the surface of the rectangular connecting tube 21. At this time, the connection between the rectangular connecting tube 21 and the clamping assembly 25 can be completed. At the same time, the first spring 16 can be provided to pull the first connecting plate 17, the first movable plate 18 and the rectangular connecting tube 21 to move upward after the connection between the rectangular connecting tube 21 and the clamping assembly 25 is completed. Since the clamping block 37 is a trapezoidal structure, when the rectangular connecting tube 21 moves upward, the clamping block 37 and the first rectangular through groove 22 opened on the surface of the rectangular connecting tube 21 can be clamped more tightly, so as to further ensure the stability of the installation of the denture crown 2.

[0037] Embodiment three, as Figure 4 , Figure 6 , Figure 7 , Fig. 9 As shown, a denture base is provided, wherein a toggle plate 20 is welded to the front end of a first movable plate 18, a rectangular connecting tube 21 is welded to the lower end of the first movable plate 18, a first rectangular through groove 22 is provided to the front end of the rectangular connecting tube 21, a second connecting plate 23 is welded inside the rectangular connecting tube 21, a triangular fixing block 24 is welded to the lower end of the second connecting plate 23, a clamping block 37 is welded to the front end of a limiting plate 36, a limiting groove 38 is provided on the front end surface of a clamping assembly 25, a magnetic plate 39 is detachably connected to the rear end of the limiting plate 36, a magnetic block 40 is detachably connected to the inner surface of the rear end of the clamping assembly 25, and the magnetic plate 39 is magnetically connected to the magnetic block 40.

[0038] When the denture crown 2 needs to be disassembled, pressing the toggle plate 20 will drive the first movable plate 18 and the rectangular connecting tube 21 to move downward. At this time, the clamping assembly 25 will continue to move deep into the inner cavity of the rectangular connecting tube 21. At the same time, under the action of the triangular fixing block 24, the clamping block 37 will be retracted again to the deep inside of the clamping assembly 25. When the clamping block 37 is fully retracted into the clamping assembly 25, the magnetic plate 39 will be magnetically connected to the magnetic block 40. At this time, the clamping block 37 will be magnetically fixed in the clamping assembly 25, and then the toggle plate 20 will be released and the denture crown 2 will be pulled upward. Since the clamping block 37 is magnetically fixed in the clamping assembly 25, when the denture crown 2 is pulled upward to move the rectangular connecting tube 21, the clamping block 37 will not be ejected from the first rectangular through groove 22 opened at the front end of the rectangular connecting tube 21. At this time, the denture crown 2 can be directly removed to complete its disassembly.

[0039] Embodiment 4, as Figure 8 , Fig. 9 As shown, a denture base is provided, wherein two groups of snap-in assemblies 25 are symmetrically welded inside the denture base 1, a second rectangular through groove 26 is provided on the top of the snap-in assembly 25, two fixed rods 27 are symmetrically welded on the top of the two fixed rods 27, limiting blocks 28 are welded on the top of the two fixed rods 27, rectangular sliding blocks 29 are slidably connected to the outer surfaces of the two fixed rods 27, a movable rod 30 is rotatably connected between the two rectangular sliding blocks 29, and a third connecting plate 31 is detachably connected to the outer surface of the movable rod 30.

[0040] The third connecting plate 31 can be set to cancel the magnetic fixation of the clamping block 37 when the denture crown 2 needs to be installed later, so that it can pop out of the clamping assembly 25, so as to avoid the clamping block 37 being continuously in the inner cavity of the clamping assembly 25 under the magnetic connection between the magnetic plate 39 and the magnetic block 40, which affects the subsequent installation and fixation of the denture crown 2. When in use, the third connecting plate 31 is pressed down, so that the movable rod 30 drives the two rectangular sliding blocks 29 to slide downward on the outer surface of the fixed rod 27. Here, since the two ends of the movable rod 30 are connected to the two rectangular sliding blocks 29 The movable connection allows the inclination angle of the movable rod 30 to be adjusted. After adjusting to a suitable angle, the third connecting plate 31 is pressed down to insert it between the magnetic plate 39 and the magnetic block 40. The third connecting plate 31 is then bent to adjust the angle so that the magnetic plate 39 is separated from the magnetic block 40. At this time, the second movable plate 35 and the limiting plate 36 will be pushed forward by the elastic force of the second spring 34 to drive the clamping block 37 to move forward. The clamping block 37 will extend from the limiting groove 38 on the surface of the clamping assembly 25, and then the denture crown 2 can be installed again.

[0041] It should be noted that the present invention is a denture base. When in use, the implant 3 is placed above the mounting hole opened in advance in the patient's alveolar bone, and then the implant 3 is rotated with the help of a hexagonal wrench in conjunction with the hexagonal hole 4 opened on the top of the implant 3 to install it in the alveolar bone. Then, after the denture base 1 is placed directly above the implant 3, the central screw 9 is passed through the denture base 1 and screwed into the screw hole 5 opened in the implant 3 to complete the installation of the denture base 1.

[0042] After the implant 3 is installed, the denture crown 2 is placed in the sealing ring 10 bonded on the placement groove 7, and then the two toggle plates 20 are pressed down to drive the first movable plate 18 and the rectangular connecting tube 21 to move downward. When the first movable plate 18 moves, the T-shaped slider 19 will slide downward in the T-shaped groove 14. After the rectangular connecting tube 21 moves downward to a certain position, the clamping assembly 25 and the clamping block 37 will slide into the inner cavity of the rectangular connecting tube 21. Since the upper end of the clamping block 37 is an inclined surface, when the clamping assembly 25 and the clamping block 37 enter the inner cavity of the rectangular connecting tube 21, the clamping block 37 will retract into the inner cavity of the clamping assembly 25, and at the same time, it will drive the limiting plate 36 to push the two second movable plates 35 to move backward, thereby The spring 34 is compressed, and after the clamping assembly 25 completely enters the inner cavity of the rectangular connecting tube 21 and the clamping block 37 moves to the rear of the first rectangular through groove 22, the clamping block 37 will be pushed out of the first rectangular through groove 22 under the action of the elastic force of the second spring 34. At this time, the connection between the rectangular connecting tube 21 and the clamping assembly 25 can be completed. At this time, the toggle plate 20 is released, and the first movable plate 18 and the rectangular connecting tube 21 will be pulled upward under the action of the elastic force of the first spring 16. Since the clamping block 37 is a trapezoidal structure, when the rectangular connecting tube 21 moves upward, the clamping block 37 and the first rectangular through groove 22 opened on the surface of the rectangular connecting tube 21 will be clamped more tightly, thereby completing the stable installation of the denture crown 2.

[0043] When the denture crown 2 needs to be disassembled, it is only necessary to press down the toggle plate 20 to drive the first movable plate 18 and the rectangular connecting tube 21 to move downward. At this time, the clamping assembly 25 will enter the deep inner cavity of the rectangular connecting tube 21. At the same time, under the action of the triangular fixing block 24, the clamping block 37 will be pushed back to the deep inner cavity of the clamping assembly 25 until the magnetic plate 39 at the rear end of the clamping block 37 is magnetically connected with the magnetic block 40, so that the clamping block 37 can be fixed in the inner cavity of the clamping assembly 25, and then the denture crown 2 is pulled upward to move. Since the clamping block 37 is fixed in the clamping assembly 25 by magnetic attraction, when the denture crown 2 is pulled upward, the clamping block 37 will not pop out from the clamping assembly 25 and clamp with the first rectangular through groove 22. Therefore, the denture crown 2 can be removed from the upper end of the denture base 1 to complete the disassembly of the denture crown 2.

[0044] When the denture crown 2 needs to be installed again, the third connecting plate 31 is first pushed to drive the movable rod 30 to move downward. At this time, the two rectangular sliding blocks 29 will slide downward on the outer surface of the fixed rod 27 with the movement of the movable rod 30 until it slides to the lowest point. Here, while pushing the third connecting plate 31 to move downward, the inclination angle of the third connecting plate 31 is adjusted so that it can be inserted between the magnetic plate 39 and the magnetic block 40 when it slides to the lowest point. Since the magnetic plate 39 is made of antimagnetic material, it can be inserted into the magnetic plate 39. When the magnetic plate 39 is between the magnetic block 40, the magnetic block 40 will not attract it. Then, the magnetic plate 39 can be separated from the magnetic block 40 by bending the third connecting plate 31 to adjust the angle. After separation, the second movable plate 35 and the limit plate 36 will be pushed forward by the action of the second spring 34, and the clamping block 37 will be popped out from the limit groove 38 opened in front of the clamping assembly 25. At this time, the clamping block 37 can be reset, and then the denture crown 2 can be placed on the upper end of the denture base 1 and installed again.

[0045] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
