Self-tapping dental implant

Abstract

The invention discloses a self-tapping dental implant which comprises an implant base body, the implant base body comprises a head part, a main body part and a tail part which are sequentially connected from top to bottom, the main body part is of a cone structure, an external thread is arranged on the outer surface of the main body part, the external thread adopts a double-line thread, at least one middle cutting groove is formed in the middle of the main body part, and at least one tail cutting groove is formed in the lower part of the main body part. The tail cutting groove comprises a straight edge and an inclined edge. And the lower end of the external thread starts from the outer end of the inclined edge. The main body part is provided with the paired middle cutting grooves and / or the paired tail cutting grooves, and the external threads are double-line threads. And the middle cutting grooves and the tail cutting grooves are spaced by 90 degrees on the circumference. The device is simple in structure and convenient to process, has good self-tapping cut-in cutting performance, can improve the initial stability of the implant, obtains double bone compression effects, and achieves the purpose of shortening the dental implant operation time.

Description

technical field [0001] The invention relates to a self-tapping dental implant, which belongs to the technical field of dental implantation. Background technique [0002] Since the 1980s, titanium dental implants have become popular all over the world; now, it has become an important and primary means of human tooth restoration, and is known as one of the greatest inventions of mankind in the 20th century. The third set of teeth", that is, after the deciduous teeth and permanent teeth, if any teeth are lost, titanium dental implant technology is used to rebuild new teeth. [0003] After that, titanium commercial dental implants appeared. This screw-type dental implant became the basis for the development of dental implants. Its basic structure is to divide artificial teeth into three parts, namely implants, abutments and teeth. Crowns where the abutments are screwed to the implant and crowns are fixed to the abutments, usually by cement. [0004] By the end of the 1990s, th...

AI Technical Summary

Problems solved by technology

[0007] For the self-tapping cutting groove on the implant, it can make the implant more convenient and labor-saving, and can reduce the unnecessary bone compression caused by the thread screwing / extrusion, but there are also problems, such as the formation of post-implantation The gap takes time to heal. For another example, the complex structure and more sharp corners it forms are not good for the jaw when the implant is stressed. In addition, after the implant is placed, due to the shape characteristics of the implant , The large gap between the implant surface and the jaw bone will take a long time to heal
