Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis technology, and in particular to a high-strength, low-density dental prosthesis. Background Technology

[0002] Dentures, also known as false teeth, are currently being used in composite dentures made of high-strength, low-density ceramics. The top component of these dentures is fixed to the bottom component only by a screw thread, resulting in poor stability. Over time, the top component of the denture is prone to loosening.

[0003] Therefore, it is necessary to provide a high-strength, low-density denture to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a high-strength, low-density denture, including a base and a first matrix. The first matrix is ​​fixedly installed on the top of the base. The surface of the first matrix has a positioning groove symmetrically formed along the center. A positioning block is slidably inserted into the surface of the positioning groove. A second matrix is ​​fixedly connected above the multiple positioning blocks. The surface of the positioning block has a positioning hole. The surface of the positioning groove has a circular groove. The surface of the circular groove is connected to a limit device by a thread. The limit device is installed in conjunction with the positioning hole.

[0005] Preferably, both the first substrate and the second substrate are made of ceramic.

[0006] Preferably, the limiting device includes a fixed post, a post groove, a spring, a movable post, and a circular block. The fixed post is threadedly connected to the surface of the circular groove. The fixed post has a post groove on its surface. The movable post is slidably connected to the surface of the post groove. A spring is fixedly connected to one end of the movable post located in the post groove. The other end of the spring is fixedly connected to the surface of the post groove. A circular block is fixedly connected to the end of the movable post away from the spring. The circular block is installed in conjunction with a positioning hole. The movable post and the fixed post are slidably connected.

[0007] Preferably, the movable column is a square prism.

[0008] Preferably, a protrusion is fixedly connected to one end of the surface of the movable column;

[0009] Preferably, the surface of the positioning hole is provided with toothed grooves symmetrically along the center, and multiple toothed grooves are slidably inserted into the circular block.

[0010] Compared with the prior art, this utility model provides a high-strength, low-density denture with the following characteristics:

[0011] Beneficial effects:

[0012] This utility model features a fixed column and a circular groove connected by threads, which limits the installation between the first base and the second base. Compared with the prior art, this ensures stable installation between the first base and the second base, thus preventing loosening. Furthermore, the spring is initially in a stretched state, and the reaction force generated by the stretched spring acts on the surface of the movable column, allowing multiple grooves to fit tightly with the circular block, limiting the rotation of the fixed column and the movable column, further ensuring stable installation of the first base and the second base.

[0019] Please see Figures 1 to 5 This utility model relates to a high-strength, low-density denture, including a base 1 and a first matrix 2. The first matrix 2 is fixedly installed on the top of the base 1. The surface of the first matrix 2 is symmetrically provided with positioning grooves 3 along the center. Positioning blocks 4 are slidably inserted into the surface of the positioning grooves 3. A second matrix 5 is fixedly connected above the multiple positioning blocks 4. Positioning holes 6 are provided on the surface of the positioning blocks 4. Circular grooves 7 are provided on the surface of the positioning grooves 3. A limiting device 8 is connected to the surface of the circular grooves 7 by a thread. The limiting device 8 is installed in conjunction with the positioning holes 6. Both the first matrix 2 and the second matrix 5 are made of high-strength, low-density ceramic.

[0020] The limiting device 8 includes a fixed post 9, a groove 10, a spring 11, a movable post 12, and a circular block 13. The fixed post 9 is threadedly connected to the surface of the circular groove 7. The groove 10 is formed on the surface of the fixed post 9. The movable post 12 is slidably connected to the surface of the groove 10. One end of the movable post 12 located in the groove 10 is fixedly connected to the spring 11. The other end of the spring 11 is fixedly connected to the surface of the groove 10. The circular block 13 is fixedly connected to the end of the movable post 12 away from the spring 11. The circular block 13 is installed in conjunction with the positioning hole 6. The movable post 12 is slidably connected to the fixed post 9, which serves as a limiting function to ensure the stable installation of the first base 2 and the second base 5. The movable post 12 is a quadrangular prism to ensure the stability of the transmission between the movable post 12 and the fixed post 9. One end of the surface of the movable post 12 is fixedly connected to a protrusion 14, which serves as a limiting function to prevent the movable post 12 from separating from the groove 10.

[0021] The surface of the positioning hole 6 is symmetrically provided with toothed grooves 15 along the center. Multiple toothed grooves 15 are slidably inserted into the circular block 13 to limit the fixed column 9 and the movable column 12 after adjustment, so as to ensure the stable fit between the fixed column 9 and the positioning groove 3, that is, to ensure the stable installation of the first base 2 and the second base 5.

[0022] Working principle and usage process of this utility model:

[0023] The first base 2 is the existing denture base component, and the second base 5 is the existing denture top component. In use, the second base 5 is inserted from top to bottom, with the positioning block 4 aligned with the positioning groove 3. The fixing post 9 is inserted into the positioning hole 6 and contacts the surface of the circular groove 7. A screwdriver with an electromagnet is used to contact the surface of the circular block 13 and attract the circular block 13. The screwdriver is pulled to move it in the direction of further stretching the spring 11. The movable post 12 slides relative to the post groove 10, and the toothed groove 15 separates from the circular block 13. The circular block 13 is rotated so that the fixing post 9 and the circular groove 7 are connected by threads and tightened. Then the screwdriver is separated from the circular block 13. Under the elastic force of the spring 11, the circular block 13 and multiple toothed grooves 15 are tightly engaged to limit the rotation of the fixing post 9 and the movable post 12, preventing them from loosening.
