Description

Technical Field

[0001] The utility model relates to the technical field of complete dentures, in particular to a complete denture three-dimensional bracket. Background Art

[0002] Complete dentures are a conventional restorative treatment for edentulous patients, which are used to restore the patient's chewing and language functions. However, the existing complete denture structure is relatively traditional, without a reasonable bracket setting, which cannot ensure the firmness of the complete denture well and is not convenient for disassembly and assembly of the abutment teeth.

[0003] A Chinese patent discloses a fixed bracket for a functional restorative full denture (authorization announcement number CN215080016U). This patented technology can easily disassemble and assemble the abutment and the base through the cooperation between the connector, the jack, the bolt hole and the fixing hole, so that it is convenient for users to carry out daily care after the abutment and the base are separated. Through the cooperation between the connecting protrusion and the slot, the fixing column will be more firmly stuck in the fixing hole and will not fall off the base easily; however, it has certain disadvantages: its specification mentions that the connecting protrusion is fixed on the outer wall of the fixing column. Therefore, when the abutment is installed and disassembled, a lot of force is needed to deform the contact surface between the abutment and the connecting protrusion so that the connecting protrusion can be stuck in the slot. The abutment is frequently squeezed and rubbed by the connecting protrusion, which is easy to wear, thereby reducing the service life. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model fixes the base and the abutment together through the installation mechanism. When installing the abutment, the docking block in the docking mechanism is first pressed into the interior of the installation tube and then extended to be inserted into the docking groove. When removing the abutment, the docking block in the docking mechanism rotates upward along with the abutment moving upward until the abutment is separated from the installation tube. The installation and removal of the entire abutment are very convenient.

[0024] The material of the mounting tube 7, the mounting block 8 and the mounting bolt 10 is preferably chrome; the mounting bolt 10 fixes the mounting tube 7 and the base 1 together, and the docking mechanism 12 is stuck in the docking groove 5, thereby fixing the mounting tube 7 and the abutment 2 together, thereby fixing the base 1 and the abutment 2 together; the outer surface of the mounting block 8 just fits the inner surface of the upper end of the first countersunk hole 3.

[0025] exist Figures 2 to 6 Middle: A limiting mechanism 20 is arranged above the docking mechanism 12 inside the mounting tube 7. The docking mechanism 12 comprises a docking tube 13. A hinge block 14 is installed at the right end of the docking tube 13. A hinge rod 15 is rotatably connected inside the hinge block 14. One end of the hinge rod 15 is installed on one side surface of the inside of the mounting tube 7. A stop rod 16 is installed on the lower surface of the docking tube 13. The lower end of the stop rod 16 fits the lower surface of the inside of the mounting tube 7. A docking rod 17 is movably connected through the left surface of the docking tube 13. A docking block 18 is installed at the left end of the docking rod 17. The docking block 18 movably passes through the strip hole 11. A first spring 19 is installed at the right end of the docking rod 17. The right end of the first spring 19 is installed on the right side surface of the inside of the docking tube 13.

[0026] The limiting mechanism 20 includes a limiting tube 21, the upper end of which is mounted on the inner upper surface of the mounting tube 7, the lower surface of which is movably connected to a limiting rod 22, the upper end of which is mounted with a second spring 23, the upper end of which is mounted on the inner upper surface of the limiting tube 21, the lower end of which is mounted with a limiting block 24, the limiting block 24 movably fits the upper surface of the butt tube 13;

[0027] The number of the strip holes 11 is preferably two or four, and they are symmetrically arranged. The number of the strip holes 11 is equal to the number of the docking mechanisms 12 and the limiting mechanisms 20;

[0028] The left surface of the docking block 18, that is, the surface facing outward, is an arc-shaped surface, the right surface is a vertical surface, and the lower surface is a horizontal surface. This allows the docking block 18 to be easily pressed into the interior of the mounting tube 7 under pressure when the abutment 2 is sleeved on the outside of the mounting tube 7.
