Description

Technical Field

[0001] The utility model relates to the technical field of artificial teeth, in particular to a cobalt-chromium alloy artificial tooth. Background Art

[0002] Dentures are artificial teeth that replace missing natural teeth, also known as false teeth; artificial teeth that replace missing natural teeth. Also known as false teeth. Severe periodontal disease, dental caries and trauma can cause partial or even complete loss of dentition. Loss of teeth can affect facial appearance, pronunciation, chewing function, and increase the burden on the stomach and intestines. If not repaired in time, adjacent teeth may tilt and shift, and the opposing teeth may elongate, causing occlusion disorder. Partial loss of dentition can be repaired with fixed or removable dentures, and complete dentures (total dentures) can be used to repair complete loss of teeth.

[0003] Chinese utility model patent CN215228659U discloses a movable cobalt-chromium alloy denture, including artificial gums, wherein a connection groove is provided at the inner middle end of the artificial gums, a positioning block is fixedly connected to the inner bottom end of the connecting groove, and a positioning hole is provided at the inner axis of the positioning block. The utility model drives the positioning block to squeeze the positioning spring by the fixing groove, so that the positioning spring is in a compressed state, and then inserts the positioning column into the positioning hole of the positioning block from the outside, so that the movable denture can be stably fixed on the artificial gums, thereby completing the assembly of the denture. When the denture needs to be maintained and replaced, the positioning column is pulled out from the artificial gums, and the positioning spring is in a stretched state to push the positioning block upward, so that the positioning block, together with the fixing groove and the movable denture, pops out of the connecting groove, which is convenient for the quick disassembly and replacement of the movable denture in the fixing groove, thereby improving the disassembly efficiency of the movable denture and the working efficiency of the denture.

[0004] However, the existing dentures have a poor anti-loosening structure, which leads to unstable installation of the dentures. In view of the above situation, technical innovation is carried out on the basis of the existing dentures. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 The utility model discloses a cobalt-chromium alloy denture, comprising a denture base 8 and a denture body 1. A metal base 5 is arranged on the denture base 8. A dovetail thread groove 6 is provided inside the metal base 5. A threaded column 4 is fixedly installed on the inner bottom wall of the dovetail thread groove 6. A bolt body 2 is fixedly installed on the bottom of the denture body 1. A plurality of bifurcated grooves 3 are evenly provided on the lower surface of the bolt body 2 near the bottom. A hollow groove 7 is provided at the bottom of the bolt body 2.

[0023] Specifically, the denture body 1 includes a base layer 12, a masking layer 11, a buffer layer 10, a toughening layer 9 and an antibacterial and antioxidant nano-ceramic layer 13, wherein the base layer 12 is provided with a masking layer 11 on its outer surface, the masking layer 11 is provided with a buffer layer 10 on its outer surface, the buffer layer 10 is provided with a toughening layer 9 on its outer surface, and the toughening layer 9 is provided with an antibacterial and antioxidant nano-ceramic layer 13 on its outer surface.

[0024] Specifically, the positions of the plurality of bifurcated grooves 3 all correspond to the positions of the hollow groove 7 , a thread is provided inside the hollow groove 7 , and the hollow groove 7 is conical.

[0025] Specifically, the threaded column 4 is tapered, and the outer surface of the threaded column 4 is connected to the inner thread of the hollow groove 7 .

[0026] Specifically, the outer surface of the bolt body 2 is connected to the inner thread of the dovetail thread groove 6, and the lower surface of the bolt body 2 is elastic.

[0027] In this embodiment, the lower surface of the bolt body 2 can avoid bifurcation when encountering a hard object, and can shrink and gather when there is no hard object.

[0028] Specifically, the outer surface of the bolt body 2 is threadedly connected to the inner surface of the dovetail thread groove 6 .

[0029] In this embodiment, the installation of the denture body 1 is strengthened.

[0030] When in use, the bolt body 2 or the denture body 1 is turned to insert the bolt body 2 into the dovetail thread groove 6. When the rotating bolt body 2 contacts the outer surface of the threaded column 4 at a position near the bottom of the lower surface of the bolt body 2, the lower surface of the bolt body 2 is bifurcated due to the hollow groove 7 and the forked groove 3 provided on the bolt body 2, resulting in the bolt body 2 still being connected to the dovetail thread groove 6, while the interior of the hollow groove 7 is threadedly connected and tightly attached to the outer surface of the threaded column 4, thereby strengthening the connection between the bolt body 2 and the dovetail thread groove 6 and ensuring that the bolt body 2 strengthens the connection between the denture body 1 and the metal base 5 without human intervention to prevent the denture body 1 from falling off. If the denture body 1 needs to be removed, the bolt body 2 can be turned to move the bolt body 2 upward, so that the hollow groove 7 is separated from the threaded column 4, thereby shrinking and gathering the forked groove 3 to facilitate the removal of the denture body 1.

[0031] To sum up, the cobalt-chromium alloy denture, by providing the bolt body 2, the bifurcated groove 3, the hollow groove 7, the threaded column 4 and the dovetail thread groove 6, can strengthen the connectivity between the bolt body 2 and the dovetail thread groove 6, thereby strengthening the connectivity between the denture body 1 and the metal base 5, and also ensure that the bolt body 2 strengthens the connection relationship between the denture body 1 and the metal base 5 without human intervention, thereby avoiding the situation where the denture body 1 is easily damaged and falls off, further increasing the protective structure of the denture body 1, and improving the service life of the denture body 1; by providing the toughening layer 9, the strength of the denture body 1 is enhanced through the toughening layer 9, so that it is not easy to break, and the thermosetting polyacrylic resin material is improved, which can improve the strength and toughness level of the denture body 1.
