Description

Technical Field

[0001] This utility model relates to the field of abutments for dental implant restoration, and more specifically, to an abutment for dental implant restoration. Background Technology

[0002] With the continuous improvement of living standards, people are paying more and more attention to health issues, and their requirements for oral health are also getting higher and higher. In addition to basic functionality, the aesthetics of teeth have also become a focus of attention. Dental implants use an implant placed in the jawbone to support the superstructure of the prosthesis. The abutment connects the implant and the superstructure crown to form a whole. It refers to a method of tooth restoration that uses a substructure implanted in the bone tissue to support and retain the superstructure of the prosthesis. It consists of two parts: the substructure, the dental implant, and the superstructure, the dental prosthesis (implant-supported). The implant is made of artificial materials (such as metal, ceramic, etc.) and is generally similar in shape to a tooth root. It is surgically implanted into the tissue (usually the upper and lower jaws) and obtains firm retention support from the bone tissue. It is then connected to the superstructure of the prosthesis through special devices and methods. Dental implants can achieve restorative results that are very similar to those of natural teeth in terms of function, structure, and aesthetics. They have become the preferred restoration method for more and more patients with missing teeth. Currently, dental implants are a mature dental treatment technology in my country. They have the advantages of being closest to natural teeth, not needing to be removed and worn every day, not needing to grind down adjacent teeth, having good chewing power, and good aesthetic results. Therefore, dental implants have become the most ideal dental restoration method. The existing abutments and implants are connected by threads. Although this connection method makes it very easy to install or remove the abutment, the abutment will become loose after the patient uses it for a long time. Once the abutment is loose, the patient's oral cavity will be easily infected and inflamed.

[0003] In the prior art, such as the authorized announcement number CN213525583U, this utility model discloses an abutment for dental implant restoration, including a medical abutment and an implant. The medical abutment and the implant are used together. A locking hole is opened on one side wall near the lower end of the medical abutment. An application groove is opened at the center of the upper surface of the medical abutment. The lower end of the application groove passes through the locking hole and extends to the bottom surface of the locking hole. A telescopic rod is movably sleeved on the inner end of the locking hole. Both ends of the telescopic rod are fixedly provided with locking heads. A spring is movably sleeved on the body of the telescopic rod. Both ends of the spring are fixedly provided with locking heads. Pulling heads are fixedly provided on both sides of the upper surface of the telescopic rod. A thin rope is fixedly provided at the center of the side wall opposite to the two pulling heads. This utility model discloses an abutment for dental implant restoration. This new abutment for dental implant restoration is more stable and safer.

[0004] In the above patent, the spring clamping structure is used for clamping installation, which is not suitable for dental parts, and the clamping structure after installation is low in tightness and cannot guarantee the firmness. Utility model content
