Detailed Implementation

[0024] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] Examples, such as Figures 1-4As shown, an adjustable denture bridge includes a bridge body 1. A mounting groove 20 is formed in the center of the bridge body 1. A spring 18 is installed on the inner wall of one side of the mounting groove 20. An adjusting bracket 5 is installed at the end of the spring 18 away from the bridge body 1. A fixing shaft 19 is installed on the inner wall of the adjusting bracket 5. A mounting bracket 10 is rotatably mounted at one end of the fixing shaft 19. Several sets of fixing holes 17 are arranged sequentially on one side of the bridge body 1. An opening matching the fixing holes 17 is formed on one side of the adjusting bracket 5. A limit screw 7 is detachably installed on one side of the fixing holes 17. A positioning hole is provided on one side of the adjusting bracket 5. A fixing screw 6 is rotatably mounted at the positioning hole. A cross-shaped groove is formed on the head of the fixing screw 6. A pressure bracket 16 is installed at one end of the fixing screw 6. The fixing holes 17... A sealing cap 3 is provided on the side, and a limiting head is provided at the tail end of the sealing cap 3. The diameter of the limiting head is slightly larger than the diameter of the fixing hole 17. An anti-dislodgement frame 2 is provided at the end of the bridge body 1 away from the connecting frame 4. The anti-dislodgement frame 2 is used to connect the denture and the denture bridge. The denture and the denture bridge adopt a split design. The split design allows for convenient replacement of the denture that is damaged during use, avoiding the need for a complete replacement and reducing later expenses. The base of the denture can be fixed to the mounting frame 10 to complete the connection between the denture and the denture bridge. During installation, the angle of the denture can be adjusted according to chewing habits by rotating the mounting frame 10 on the fixed shaft 19. The mounting frame 10 and the fixed shaft 19 are equipped with a certain amount of damping to prevent the mounting frame 10 from rotating when not adjusted. After the angle adjustment is completed, pressing the filling frame 9, in conjunction with the deformation of the spring 18, allows the adjusting frame 5 to slide within the mounting slot 20 of the bridge body 1, thus adjusting the height of the denture. This allows for adaptive adjustment of each tooth, making it more suitable for the user's chewing style. When the height adjustment is complete, align the opening of the adjusting frame 5 with a set of fixing holes 17 corresponding to its height. After alignment, install the limiting screw 7 through the fixing holes 17 to complete the limiting between the bridge body 1 and the adjusting frame 5, thereby preventing the denture from changing height or springing back when not adjusted. The fixing screw 6 can be rotated and installed in the positioning hole of the adjusting frame 5. The cross-shaped groove of the fixing screw 6 is compatible with a screwdriver. Rotating the mounting frame 10 completes the angle adjustment of the denture. After the holiday, by controlling the rotation of the fixing screw 6, the rubber pressure frame 16 moves closer to the mounting frame 10. The pressure frame 16 contacts the mounting frame 10 and presses it to fix it, thus limiting the movement and preventing the mounting frame 10 from rotating when not in use or chewing. Only one set of fixing holes 17 is needed to limit and fix the adjusting frame 5. When not in use, the other sets of fixing holes 17 can be sealed with sealing caps 3 to prevent food residue from entering during chewing. In order to facilitate quick installation of the bridge body 1, the anti-detachment frame 2 can be glued to the gum first. After the gluing is completed, the position and angle of the bridge body 1 can be adjusted and connected in multiple sets before fixing it to the anti-detachment frame 2 to quickly complete the connection between the bridge body 1 and the gum.

[0026] Furthermore, such as Figure 2 and Figure 3 , Figure 4 As shown, a rotating seat 14 is installed at the end of the mounting bracket 10 away from the bridge body 1. The rotating seat 14 has several sets of positioning holes arranged in a circle. A denture base 11 is rotatably mounted at one end of the rotating seat 14. The denture base 11 is adapted to the rotating seat 14. The denture base 11 has several sets of limiting holes 13 arranged in a circle. The limiting holes 13 are adapted to the positioning holes of the rotating seat 14. A limiting bolt 12 is installed on one side of the limiting hole 13. A washer 15 is provided on one side of the mounting bracket 10. The washer 15 is used to reinforce the denture base 11. After the denture is fixed to the denture base 11, the denture base 11 is aligned with the rotating seat 14 for installation. After installation, the denture base 11 can be rotated. This allows for adjustment of the denture's direction as needed, making installation more convenient and allowing for easy adjustment as required. After adjustment, the positioning holes of the limiting hole 13 and the rotating seat 14 are aligned. After alignment, the limiting bolt 12 is tightened through the limiting hole 13 to fix the rotating seat 14 and the denture base 11, thus completing the connection between the denture and the bridge 1 and preventing unnecessary rotation of the denture during chewing. The washer 15 is made of rubber and its position and size are adapted to the rotating seat 14. When installing the denture base 11, the washer 15 can fill the gap at the connection point, thereby reinforcing the connection and preventing the denture base 11 from shaking after installation.

[0027] Furthermore, such as Figure 1 and Figure 2 As shown, four sets of filling frames 9 are symmetrically installed on both sides of the adjustment frame 5. The filling frames 9 are used to limit the movement trajectory of the adjustment frame 5. A set of connecting frames 4 are installed at each end of the bridge body 1. The connecting frames 4 have connecting holes, and fixing bolts 8 can be detachably installed in the connecting holes. There is a certain gap between the adjustment frame 5 and the mounting groove 20 of the bridge body 1, which may cause the adjustment frame 5 to tilt when moving up and down. The filling frames 9 on the outer wall of the adjustment frame 5 can fill the gap between the adjustment frame 5 and the mounting groove 20, thereby limiting its movement trajectory and preventing the adjustment frame 5 from tilting or shifting during movement, which may affect the denture. Multiple sets of bridge bodies 1 can be arranged in sequence, and the position and angle of multiple sets of bridge bodies 1 can be adjusted to correspond to the position and curvature of the jawbone. After completion, the connecting frames 4 of two adjacent sets of bridge bodies 1 are aligned. After alignment, the fixing bolts 8 are tightened through the connecting holes to complete the connection and fixation between the bridge bodies 1. The design of the split denture bridge has stronger adaptability and is easier to adjust according to the user's oral condition. Compared with the one-piece molded denture bridge, it has better adaptability and comfort.

[0028] like Figures 1-4 As shown in this embodiment, the principle of an adjustable denture bridge is as follows:

[0029] Multiple bridge bodies 1 are arranged sequentially and connected by connecting brackets 4 and fixing bolts 8. After connection, the angle of the bridge body 1 is adjusted according to the shape and curvature of the gums in the oral cavity to adapt it to the gums and reduce foreign body sensation. The anti-dislodgement bracket 2 is bonded to the gums, and the bridge body 1 is connected to the anti-dislodgement bracket 2 to complete the assembly. During installation, the denture base 11 is installed on the rotating seat 14 and rotated to adjust the direction of the denture as needed. After adjustment, the limiting bolts 12 are installed through the limiting holes 13 to complete the connection between the denture base 11 and the rotating seat 14. The adjustment bracket is pressed. The height of the denture is adjusted by the deformation of the spring 18. After adjustment, the limiting screw 7 is installed through the fixing hole 17 to limit and fix the adjusting frame 5, so as to prevent the denture from springing back or changing its position. The angle of the denture can be adjusted by controlling the rotation of the mounting frame 10. After adjustment, the fixing screw 6 is tightened, and the mounting frame 10 is fixed by the pressing frame 16, so as to prevent the angle of the denture from changing during chewing. The height, direction and angle of the denture can be conveniently adjusted as needed to adapt to the user's chewing habits.
