Description

Technical Field

[0001] The utility model relates to the technical field of screw connection of an implant base, in particular to a screw connection structure of an implant base. Background Art

[0002] Dental implants are also called oral implants or artificial tooth roots. They are implanted into the upper and lower jaws of the toothless part of the human body through surgical procedures. After the surgical wound heals, a device for repairing simulated teeth is installed on the upper part. The simulated teeth are connected to the top of the base, and then the base is connected to the screw structure below. The screws and implants are connected so that the implants are implanted into the toothless part of the human body.

[0003] The existing Chinese utility model patent with reference announcement number: CN206809352U discloses a connection structure of a dental implant base and an implant. The utility model comprises a connecting rod, a base, an implant and a screw. The connecting rod comprises a rotary locker, a locking disc, a spring washer, a cylinder, an anti-skid textured surface and a bolt. The lower end of the rotary locker is connected to the locking disc, the lower end surface of the locking disc is provided with a spring washer, the lower end of the locking disc is connected to the cylinder, the arc surface below the cylinder is provided with an anti-skid textured surface, the lower end of the cylinder is provided with a bolt, and the base is an overall hollow structure. The utility model has a novel structure, a scientific design, a simple structure and is easy to operate. The base and the implant are fixed by rotating the bolt through the rotary locker. The spring washer plays a role of pre-tightening force in the vertical direction, so that the base and the implant are not easy to loosen. At the same time, the spring at the front end of the screw presses the anti-skid textured surface on the connecting rod, which plays a role of pre-tightening force in the horizontal direction, greatly improving the reliability of the connection between the base and the implant.

[0004] The existing simulated tooth is connected above the abutment, and the bottom of the abutment is installed on the inner wall of the implant through a central screw. However, the connection between the abutment and the central screw is single, so when the simulated tooth is used, if the simulated tooth is hit by the gravity of an object, the abutment and the screw are easily loosened under the force, which affects the use effect of the connection between the abutment and the screw and reduces the use of the implanted simulated tooth.
