Closed implants with spontaneous elastic expansion

Abstract

The invention discloses a closed implant with the function of spontaneous elastic expansion, which is used for the restoration of teeth in dental implant surgery. , the implant has a bifurcation, and the internal lock is placed in the bifurcation of the implant, and the bifurcation and the internal lock fit together to fold the implant; when the implant is implanted in the jaw, the internal lock is pushed by the tooth socket Slide to release the restraint of fitting with the bifurcation part of the implant, and the bifurcation part automatically returns to the initial expansion state. The present invention pushes the internal lock into the implant through the thrust generated when the implant is implanted into the jawbone, so that the internal lock and the bifurcated part of the implant are disengaged, and the end of the implant automatically bounces off, forming a Extrusion increases the initial stability of the dental implant; and the slit expansion part of the bifurcation part of the implant does not form an internal channel to connect with the external oral cavity, preventing micro-leakage of bacteria and ensuring the long-term success rate of the implant.

Description

technical field [0001] The invention relates to a medical device, in particular to an implant widely used in the field of oral implantation. Background technique [0002] Because dental implant restoration is more reliable and comfortable than traditional fixed bridges and removable denture restorations, implants have been more and more widely used and developed. According to the survey, about 50% of patients with missing teeth in developed countries choose implants to restore missing teeth. With the continuous economic development in my country, the annual use of implants is also growing rapidly at a rate of more than 100%. [0003] Due to the individual differences in the oral conditions of patients, the existing implant system has certain limitations. For example, the initial stability of the implant is not good after implant restoration in patients with insufficient alveolar bone or osteoporosis. Clinical analysis shows that the main reason for the failure of implant su...

AI Technical Summary

Problems solved by technology

The existing implants on the market can only provide cylindrical or conical implants of fixed specifications, relying on the thread to provide the initial stability of the implant, for patients with poor alveolar bone quality or patients with immediate implant surgery The initial stability of the implant is insufficient, which greatly increases the risk of implant failure

[0004] In addition, the existing implants with expansive design at home and abroad are without exception designed with an internal channel structure that penetrates the oral cavity and the bone tissue at the expansion site. A large number of clinical cases have confirmed that the microleakage of the implant will cause the tissue around the implant to be infected by bacteria. and absorption, leading to loosening and failure of the implant
