Description

Technical Field

[0001] The utility model relates to the technical field of artificial teeth, in particular to an anti-loosening artificial tooth implant. Background Art

[0002] Dentures are artificial teeth that replace missing natural teeth, also known as false teeth. Due to severe periodontal disease, caries and trauma, partial or even complete loss of dentition may occur. Missing teeth may affect facial appearance, pronunciation, chewing function, and increase the burden on the gastrointestinal tract. If not repaired in time, adjacent teeth may tilt and shift, and the opposing teeth may elongate, causing malocclusion. Partial loss of dentition can be repaired with fixed or removable dentures. When there is no teeth at all, full dentures can be used to repair it. Before the denture is installed, implants need to be installed in the patient's alveolar bone in advance. After the implant and the alveolar bone are fully grown together, the denture and implant are installed together. The installation method is threaded engagement installation. If the torque of the abutment is too large, it is easy to cause the implant to shake on the alveolar bone, affecting the combination of the implant and the alveolar bone.

[0003] In the utility model patent with patent publication number CN219397680U, an extrusion block connection is adopted between the abutment and the implant, that is, the corresponding two extrusion blocks are squeezed into the corresponding docking holes by using the V-shaped spring clip inside the abutment, so as to achieve the effect of fixing the connection part between the abutment and the implant, and avoid the secondary problems caused by the threaded connection. Although this method can solve the above-mentioned technical problems, it also has the problem that the extrusion block always relies on the thrust of the spring clip to maintain its position, and the denture, as a replacement for teeth, needs to be chewed for a long time. If the spring clip is damaged after long-term use, it cannot fix the denture, which reflects the singleness of the fixation of the above-mentioned technical means and cannot provide better fixation stability.

[0004] Therefore, it is necessary to provide a denture implant that prevents loosening to solve the above technical problems. Utility Model Content

[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a denture implant that prevents loosening to solve the problem that the existing denture implant always relies on the thrust of the spring to maintain its position because the extrusion block, and the denture is used to replace teeth, and it is necessary to perform long-term chewing actions. If the spring is damaged after long-term use, it will not be able to fix the denture, which reflects the singleness of the fixation of the above-mentioned technical means and cannot provide better fixation stability.
