[0002] Dentures are teeth that fulfill human "duties". In medicine, they are a general term for restorations made after partial or complete loss of the upper and lower jaw teeth. Dentures are divided into two types: removable and fixed. However, regardless of whether they are removable or fixed, the dentures must be neatly arranged during the manufacturing process.

[0003] Among them, announcement number CN221285961U discloses a dental prosthesis occlusal frame, which adopts a spring telescopic component to adjust the upper fixed frame, thus making it suitable for various specifications of dental prosthesis frames. It has high applicability, not only saving a lot of resources, but also reducing the space occupied, resulting in high economic benefits.

[0004] The device fixes the denture framework through the lower fixation frame and the lower fixation frame through hole.

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0034] This utility model provides, for example Figures 1 to 3 The illustrated dental prosthesis occlusal articulator includes a fixed frame 1 and a fixed plate 2. A first support frame 11 is fixedly connected to the rear end of the fixed frame 1, and a second support frame 21 is fixedly connected to the rear end of the fixed plate 2. A rotating shaft 22 is fixedly connected to the lower end of the second support frame 21, and the rotating shaft 22 is rotatably connected to the upper end of the first support frame 11. Two sets of fixing components are provided between the fixed frame 1 and the fixed plate 2. The fixing components include a fixed tray 3, a first support block 31, a positioning groove 32, a positioning slider 33, a second support block 34, a threaded hole 35, a connecting plate 36, a limiting groove 37, a transmission rod 38, a limiting ring 39, a positioning screw 310, and a connecting block 311.

[0035] The first support frame 11 rotates around the second support frame 21, which facilitates the adjustment of the position of the upper and lower denture brackets and the fabrication of dentures. During the process of fixing the denture brackets, the denture brackets are placed on the surface of the fixing tray 3. At this time, the first support block 31 and the second support block 34 cooperate to fix the denture brackets, which effectively improves the fixing speed of the denture brackets and improves the ease of use.

[0036] See Figure 2 and Figure 3The left and right sides of the rear end of the fixed tray 3 are fixedly connected to the first support block 31. The positioning groove 32 is longitudinally opened at the center of the fixed tray 3. The positioning slider 33 is slidably connected to the positioning groove 32. The second support block 34 is fixedly connected to the front end of the positioning slider 33. The connecting plate 36 is fixedly connected to the rear end of the fixed tray 3. The limiting groove 37 is opened at the center of the connecting plate 36. The limiting ring 39 is fixedly connected to the surface of the transmission rod 38. The transmission rod 38 and the limiting ring 39 are rotatably connected to the limiting groove 37. The positioning screw 310 is fixedly connected to the front end of the transmission rod 38. The threaded hole 35 is opened inside the positioning slider 33. The positioning screw 310 is threadedly connected to the threaded hole 35.

[0037] Specifically, before fixing the denture framework, the upper and lower denture frameworks are temporarily fixed with wax to ensure that they are aligned. Then, the transmission rod 38 is rotated counterclockwise, which drives the positioning screw 310 to rotate clockwise. This, in conjunction with the threaded hole 35, pushes the positioning slider 33 forward, thereby pushing the second support block 34 forward until the distance between the second support block 34 and the first support block 31 is greater than the front-to-back width of the denture framework. At this point, the denture framework is placed on the surface of the lower fixing tray 3, with its rear end abutting against the surfaces of the two rear first support blocks 31. The transmission rod 38 is then rotated counterclockwise, which drives the positioning screw 310 to rotate counterclockwise. This, in conjunction with the threaded hole 35, slides the positioning slider 33 backward until the second support block 34 abuts against the surface of the denture framework. At this point, the second support block 34 and the first support block 31 work together to clamp and fix the lower denture framework.

[0038] See Figure 1 and Figure 4 Two sets of fixing components are arranged opposite each other between the fixing frame 1 and the fixing plate 2. The lower surface of the lower fixing tray 3 is fixedly connected to the fixing frame 1, and the upper surface of the upper fixing tray 3 is fixedly connected to the connecting block 311. The middle part of the fixing plate 2 is threadedly connected to the lifting screw 26, and the lower end of the lifting screw 26 is rotatably connected to the connecting block 311. The front and rear sides of the fixing plate 2 are slidably connected to the positioning rod 27, and the lower end of the positioning rod 27 is fixedly connected to the upper surface of the upper fixing tray 3.

[0039] In addition, after the lower denture bracket is fixed, during the process of fixing the upper denture bracket, firstly rotate the lifting screw 26 to push the upper fixing tray 3 downward, so that the lower surface of the upper fixing tray 3 abuts against the upper surface of the upper denture bracket. Then, the positioning screw 310 drives the positioning slider 33 to slide backward, which, together with the first support block 31 and the second support block 34, fixes the upper denture bracket, effectively improving the fixing speed of the denture bracket.

[0040] See Figure 1 and Figure 5An adjusting rod 12 is fixedly connected to the side of the upper end of the first support frame 11. A positioning plate 13 is fixedly connected to the middle of the rear end of the adjusting rod 12. A telescopic rod 14 is slidably connected to the center of the positioning plate 13. A support spring 15 is sleeved on the surface of the telescopic rod 14. A protrusion is fixedly connected to the front end of the telescopic rod 14. The two ends of the support spring 15 abut against the surface of the protrusion and the positioning plate 13, respectively. An abutment plate 25 is fixedly connected to the upper side of the middle of the rotating shaft 22. The protrusion at the front end of the telescopic rod 14 abuts tightly against the surface of the abutment plate 25. An L-shaped adjusting plate 23 is fixedly connected to the lower side of the middle of the rotating shaft 22. An adjusting screw 24 is threadedly connected to the lower side of the adjusting plate 23. The upper end of the adjusting screw 24 abuts against the lower surface of the adjusting rod 12.

[0041] Meanwhile, during the denture processing, rotating the adjusting screw 24 clockwise pushes it upwards. Since the position of the adjusting rod 12 is fixed, the adjusting plate 23 rotates downwards around the rotating shaft 22, causing the second support frame 21 to rotate upwards around the rotating shaft 22, moving the upper denture bracket upwards. At the same time, the abutment plate 25 presses against the telescopic rod 14 and the support spring 15. Conversely, rotating the adjusting screw 24 counterclockwise pulls it downwards. Without the support of the adjusting screw 24, the support spring 15 pushes the telescopic rod 14 forward, which in turn pushes the abutment plate 25 forward, causing the second support frame 21 to rotate downwards around the rotating shaft 22, resetting the second denture bracket.

[0042] The working principle of this utility model is as follows: By placing the denture bracket on the surface of the fixed tray 3, the positioning screw 310 is rotated to drive the positioning slider 33 to slide backward. The first support block 31 and the second support block 34 cooperate to clamp and fix the denture bracket, which effectively improves the fixing efficiency of the denture bracket and the denture processing efficiency. The positioning slider 33 can slide back and forth, which is convenient for denture brackets of different sizes. At the same time, by rotating the lifting screw 26, the upper fixed tray 3 can be raised or lowered, thereby adjusting the distance between the upper and lower fixed trays 3, so that it can be used for denture brackets of different heights, further improving the adaptability and ease of use of the equipment.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
