Description

Technical Field

[0001] The utility model relates to the technical field of oral dental implants, in particular to a fixing structure for oral dental implants. Background Art

[0002] Dental implants are implanted into the upper and lower jaws of the human body where the teeth are missing through surgical procedures. After the surgical wound heals, a device for repairing dentures is installed on the upper part. The key to dental implants lies in the implant part, which is equivalent to the root of the real tooth and plays a vital role in the fixation of the entire tooth. Implant dentures are also called dental implants. They have become one of the conventional treatments for repairing edentulous or missing teeth. Clinically, it is required that the implant and bone tissue can achieve good bone bonding. Titanium and titanium alloys are currently the most widely used dental implant materials due to their good biocompatibility and ideal mechanical properties. Repairing tooth defects or missing teeth through implant technology can achieve a harmonious and natural aesthetic effect between the patient's oral and facial appearance, and also help improve chewing function. The effect can generally last for more than 10 years. At present, dental implants, i.e., fixed dentures implanted in the bone, are an advanced way to repair autologous tooth loss in oral medicine. The so-called dental implant technology is to drill implant holes on the patient's gums with a drill after the patient's teeth are missing, and then fix artificial ones in the implant holes.

[0003] However, the implant and the base in the existing dental implant are fixed by only a single thread locking method, which may cause the base and the implant to loosen over time. Therefore, we propose a fixing structure for oral implants.

[0004] An oral implant orthodontic fixing structure disclosed in the publication number CN215425220U, although, the oral implant orthodontic fixing structure relates to the field of oral dental implant technology. It includes an implant, a base and a denture body, the top of the implant is movably provided with a base, the top of the base is movably provided with a denture body, the top of the base is provided with a mounting groove, the interior of the mounting groove is provided with two movable grooves, the interior of the mounting groove is movably provided with a screw, the two ends of the screw extend to the interior of the two movable grooves respectively, the surface of the screw is movably provided with a positioning block, the interior of the base is provided with a stable cavity, one end of the screw penetrates into the interior of the stable cavity and is fixedly provided with an adjustment block. By providing an implant, a base and a denture body, the positioning block is driven to connect or separate with the positioning groove by rotating the screw, thereby completing the assembly and disassembly of the denture body, the operation method is simple and fast, and the usability of the device is guaranteed.

[0005] Although the above patent achieves the assembly and disassembly of the denture body by rotating the screw to drive the positioning block to connect or separate with the positioning groove, the operation is simple and quick, ensuring the usability of the device; however, the device lacks the function of adjusting the angle between the denture and the base to ensure that the denture can achieve the best fit and function with the patient's natural teeth, adjacent restorations or occlusal surfaces, and avoid poor occlusion due to incorrect angles, thereby affecting the chewing function and stability of the teeth.

[0006] Therefore, it is necessary to invent a fixing structure for oral implants to solve the above problems. Utility Model Content

[0017] (III) Beneficial effects

[0018] The utility model provides a fixing structure for oral implants, which has the following beneficial effects:
