[0032] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0033] Please refer to Figures 1 to 10 The embodiment of the utility model provides an oral diagnosis and treatment articulator, comprising a bottom bracket 1 and a top bracket 6, wherein the bottom bracket 1 and the top bracket 6 are connected via a telescopic component.

[0034] Among them, the telescopic assembly includes a pair of hollow rods 2 located on the bottom bracket 1, a telescopic rod 3 is slidably arranged in the hollow rod 2, the upper end of the telescopic rod 3 is connected to the top bracket 6, and the top bracket 6 slides into the hollow rod 2 through the telescopic rod 3 and approaches the bottom bracket 1.

[0035] Since a support plate 9 is provided on one side of both the bottom bracket 1 and the top bracket 6, and an adjustable occlusal assembly is installed on both support plates 9, when the top bracket 6 is close to the bottom bracket 1, the dental model is fixed.

[0036] Secondly, a spring 1 4 is arranged inside the hollow rod 2, and the lower end of the telescopic rod 3 is connected to the spring 1 4. When the telescopic rod 3 slides downward, the spring 1 4 is squeezed. At the same time, a spring 2 5 is sleeved on the outer side of the hollow rod 2, and the lower end of the spring 2 5 is connected to the lower end of the hollow rod 2, and the upper end of the spring 2 5 is connected to the upper end of the telescopic rod 3. When the telescopic rod 3 slides downward, the spring 2 5 is squeezed at the same time. Through the elastic action of the spring 1 4 and the spring 2 5, the force for fixing the dental mold is buffered to prevent the dental mold from being damaged.

[0037] It is worth mentioning that a positioning rod 7 is fixedly provided on one side of the bottom bracket 1, and the upper end of the positioning rod 7 passes through the top bracket 6 and is connected to a nut. At the same time, a positioning rod 2 8 is fixedly provided on one side of the support plate 9 located on the lower side, and the upper end of the positioning rod 2 8 passes through the support plate 9 located on the upper side and is connected to a nut. The top bracket 6 is fixed by using the positioning rod 1 7 and the positioning rod 2 8 to improve the fixing effect.

[0038] In order to adjust the size of the adjustable bite assembly, one end of the adjustable bite assembly is movably connected to one side of the support plate 9, and the tilt angle is adjusted by moving the other end of the adjustable bite assembly up and down.

[0039] Specifically, the adjustable bite assembly includes a bearing plate 10 hinged to one end of a support plate 9, a U-shaped plate 14 is provided on the upper side of the bearing plate 10, bite rods 11 are slidably provided at both ends of the U-shaped plate 14, and the dental model can be placed on the bite rods 11.

[0040] At the same time, an extension plate 13 is arranged on one side of the bite rod 11, and the extension plate 13 is used to support the dental model.

[0041] One end of the two bite rods 11 is slidably connected to the slide groove 15 opened on one side of the U-shaped plate 14, and a screw rod 17 is rotatably set on one side of the U-shaped plate 14. The two bite rods 11 are respectively threadedly connected to the two ends of the screw rod 17. The screw rod 17 is symmetrical with the center and the thread directions on the left and right sides are opposite. When the screw rod 17 is rotated, the two bite rods 11 approach or move away from each other, thereby adjusting the distance between the two bite rods 11, so that the entire adjustable bite assembly can be used to meet the needs of dental molds of different sizes.

[0042] In order to connect the two bite rods 11 via the spring three 12, the spring three 12 can provide a restoring force to ensure that the bite rod 11 can stably maintain the set position after the adjustment is completed, rather than moving due to the removal of external force.

[0043] Furthermore, a moving block 16 is hinged on one side of the supporting plate 10, and the moving block 16 is threadedly connected to a screw rod 18 rotatably arranged on the supporting plate 9. By rotating the screw rod 18, the moving block 16 moves upward with one end of the supporting plate 10. Since the supporting plate 10 is hinged to the supporting plate 9, the supporting plate 10 is in an inclined state, thereby adjusting the inclination of the supporting plate 9 to simulate the occlusal relationship.

[0044] In summary, the working principle of an oral diagnosis and treatment articulator in an embodiment of the utility model is: rotating screw rod 2 18 to move the moving block 16 upward, and the moving block 16 moves upward with one end of the supporting plate 10, so that the supporting plate 10 is tilted to simulate the movement of the temporomandibular joint. By rotating screw rod 17, the two bite rods 11 are brought closer to each other and the spring three 12 is squeezed. By moving the two bite rods 11, the distance between the bite rods 11 is adjusted, so that the entire adjustable bite assembly can be adjusted according to dental molds of different sizes. After the two dental molds are aligned, the telescopic rod 3 is pressed downward to fix the upper adjustable bite assembly to the dental mold downward and fix it with a nut.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
