DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0026] The embodiment of the present application discloses a combination of a fixed denture and a removable denture.

[0027] A combination of fixed denture and removable denture, referring to Figure 1-3, including a fixed denture 1, a positioning bar 2, and a movable denture 3. The positioning bar 2 is fixed between the fixed dentures 1. There are several fixed dentures 1, wherein the positioning bar 2 is fixedly connected between several fixed dentures 1. An implant screw 11 is fixedly provided at the bottom of the fixed denture 1. The positioning bar 2 is arc-shaped. The fixed denture 1 can be fixed in the patient's mouth by the implant screw 11, and the arc-shaped positioning bar 2 can match the shape of the oral cavity.

[0028] Reference Figure 1 、 Figure 3 and Figure 4 The movable denture 3 is installed on one side of the positioning bar 2. A connecting mechanism is provided between the positioning bar 2 and the movable denture 3. The movable denture 3 can be installed at the corresponding position of the positioning bar 2 to be combined with the fixed denture 1, so that the dentures can better cooperate with each other and are convenient for normal use.

[0029] Reference Figure 1 、 Figure 4 and Figure 5 The connecting mechanism includes a plurality of mounting square holes 21 provided on the top of the positioning bar 2, and a mounting block 32 fixed on one side of the movable denture 3 and plugged into the top of the mounting square hole 21. A fixing hole 23 is provided in the mounting square hole 21, and an elastic fixing piece for inserting into the fixing hole 23 under elastic force is provided in the mounting block 32. A connecting rod 31 is fixed on one side of the movable denture 3, and the mounting block 32 is fixedly installed at the bottom end of the connecting rod 31. The connecting rod 31 can connect the movable denture 3 with the mounting block 32. The mounting block 32 is inserted into the corresponding mounting square hole 21, which can preliminarily connect the movable denture 3 and the positioning bar 2, and the mounting square hole 21 is square, which helps to quickly align the elastic fixing piece with the fixing hole 23.

[0030] Reference Figure 1 、 Figure 4 and Figure 5 A slide groove 33 is provided on one side of the mounting block 32. The elastic fixing member includes a second spring 34 fixed in the slide groove 33, and a trapezoidal block 35 fixed at one end of the second spring 34 and inserted into the fixing hole 23. One end of the trapezoidal block 35 is slidably connected to the corresponding slide groove 33, and the other end of the trapezoidal block 35 is provided with an inclined surface for guiding. The mounting block 32 can support and limit the trapezoidal block 35 through the slide groove 33.

[0031] When the mounting block 32 is inserted into the mounting square hole 21, under the guidance of the inclined surface of the trapezoidal block 35, the trapezoidal block 35 will be completely pressed into the slide groove 33. At this time, the second spring 34 is compressed. As the mounting block 32 continues to move downward, the fixing hole 23 will be aligned with the trapezoidal block 35. Under the elastic force of the second spring 34, the inclined end of the trapezoidal block 35 will be inserted into the fixing hole 23, thereby connecting and fixing the positioning bar 2 and the mounting block 32, and completing the installation of the movable denture 3.

[0032] Reference Figure 1 、 Figure 4 and Figure 5 A plurality of disassembly holes 22 are provided at the top of the positioning bar 2. A sealing plate 24 for blocking the top opening is slidably provided in the mounting square hole 21 and the disassembly hole 22. A first spring 25 is fixedly provided at the bottom inner side of the mounting square hole 21 and the disassembly hole 22 to push the sealing plate 24 upward. The sealing plate 24 of the mounting square hole 21 is fitted against the bottom of the mounting block 32. The bottom of the sealing plate 24 is fixedly connected to the top of the first spring 25. Under the elastic force of the first spring 25, the sealing plate 24 can be driven to move upward to seal the top openings of the mounting square hole 21 and the disassembly hole 22, thereby preventing water stains or foreign matter in the oral cavity from entering and corroding the components in the mounting square hole 21 and the disassembly hole 22.

[0033] Reference Figure 1 、 Figure 4 and Figure 5 The bottom of the sealing plate 24 of the disassembly hole 22 is provided with a pressing mechanism for pushing the elastic fixing piece out of the fixing hole 23 after the sealing plate 24 moves down. The pressing mechanism includes a vertical rod 4 fixed to the bottom of the sealing plate 24 of the disassembly hole 22, an oblique rod 41 rotatably connected to the bottom of the vertical rod 4, and a cross rod 42 rotatably arranged at the bottom end of the oblique rod 41. One end of the cross rod 42 is slidably connected to the top of the fixing hole 23, and the end of the cross rod 42 away from the oblique rod 41 cooperates and abuts with the inclined end of the trapezoidal block 35. The oblique rod 41 can connect the vertical rod 4 and the cross rod 42, and the positioning bar 2 can limit the cross rod 42 through the fixing hole 23, so that the cross rod 42 can only move laterally.

[0034] When the staff uses a tool to press down the sealing plate 24 of the disassembly hole 22, the vertical rod 4 will be driven to move downward, and the downward-moving vertical rod 4 will push the bottom oblique rod 41 obliquely. The oblique rod 41 after oblique movement will push the cross rod 42 toward the side of the mounting block 32. The moved cross rod 42 will push the trapezoidal block 35 out of the fixing hole 23 laterally. At this time, the staff can pull the mounting block 32 out of the positioning bar 2 to remove and replace the movable denture 3.

[0035] The implementation principle of the combination of fixed denture and removable denture in the embodiment of the present application is as follows:

[0036] When the movable denture 3 needs to be installed, the staff can insert the mounting block 32 on one side of the movable denture 3 into the corresponding mounting square hole 21. At this time, under the guidance of the inclined surface of the trapezoidal block 35, the trapezoidal block 35 will be completely pressed into the slide groove 33, so that the second spring 34 is compressed. As the mounting block 32 continues to move downward, the fixing hole 23 will be aligned with the trapezoidal block 35. Under the elastic force of the second spring 34, the inclined surface end of the trapezoidal block 35 will be inserted into the fixing hole 23, thereby connecting and fixing the positioning bar 2 and the mounting block 32, and completing the installation and fixing process of the movable denture 3;

[0037] When the movable denture 3 needs to be disassembled, the staff can use a tool to press down the sealing plate 24 of the disassembly hole 22 to drive the vertical rod 4 to move downward. The downwardly moved vertical rod 4 will push the bottom oblique rod 41 obliquely. The oblique rod 41 after oblique movement will push the cross rod 42 toward the side of the mounting block 32. The moved cross rod 42 will push the trapezoidal block 35 out of the fixing hole 23 laterally. At this time, the staff can pull out the mounting block 32 from the positioning bar 2 to remove and replace the movable denture 3.

[0038] Furthermore, by combining the movable denture 3 and the fixed denture 1, the dentures can be better matched with each other, making normal use more convenient.

[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
