Problems solved by technology

[0002] At present, the application of titanium implants has become a routine method to replace missing teeth. The soft tissue around the implant is mainly composed of a connective tissue layer composed of gingival fibroblasts and an epithelial layer composed of epithelial cells, such as figure 1 As shown, the cells around the smooth collar 11 of the traditional implant 1 have a tendency to migrate and grow with the side, and the connective tissue is combined with it in a parallel attachment relationship, which is different from the growth of natural periodontal tissue embedded in the tooth, thus weakening the implant. The ability to bind to the surrounding connective tissue, while it is traditionally believed that a rough collar will lead to the adhesion of surrounding bacteria, which is not conducive to patient recovery

Abstract

The invention relates to a dental implant. The technical essential is that a groove is formed in the surface of a neck strap of the dental implant. A titanium nitride (TiN) coating is formed on the surface of the groove, and the coating is 100-1000nm thick. Surface feature of anisotropism of the horizontal groove of the dental implant can generate a contact induction effect to gum fibroblast, which means that the fibroblast can be guided to grow along the direction of the horizontal groove. Forming of a peripheral seal of the dental implant by the gum fibroblast is facilitated due to the contact induction effect, which means that the fibroblast can be guided to grow along the horizontal trend of the groove to accelerate well union of surrounding soft tissues of the dental implant and prevent epithelial migration with the direction and bacterial invasion, so as to realize peripheral seal of the implant and ensure the long-term stability of the implant. The micro-groove is combined with the TiN nano coating, so that the dental implant has good antibacterial property and good blood compatibility, effectively accelerates platelet adhesiveness and activation, and has good biocompatibility. Meanwhile, the dental implant effectively promotes proliferation and adhesion of the gum fibroblast.

Description

technical field [0001] The invention relates to implants, in particular to dental implants. Background technique [0002] At present, the application of titanium implants has become a routine method to replace missing teeth. The soft tissue around the implant is mainly composed of a connective tissue layer composed of gingival fibroblasts and an epithelial layer composed of epithelial cells, such as figure 1 As shown, the cells around the smooth collar 11 of the traditional implant have a tendency to migrate and grow with the side, and the connective tissue is combined with it in a parallel attachment relationship, which is different from the growth of natural periodontal tissue embedded in the tooth, thus weakening the implant. The ability to combine with the surrounding connective tissue, while traditionally believed that the rough collar will lead to the adhesion of surrounding bacteria, which is not conducive to the recovery of patients.
