摘要： Provided are a dental implant with a nano bacteriostatic structure ring at a transgingival part and a machining method thereof. The transgingival part of the dental implant has a three-level micro-nano composite structure, and the three-level micro-nano composite structure endows a surface of the transgingival part of the implant with functions of promoting adhesion and proliferation of a gingival fibroblast and a gingival mesenchymal stem cell and inhibiting adhesion and growth of various oral bacteria. A preparation method thereof comprises: firstly, injecting bioactive, wear-resistant or corrosion-resistant C, N, Ca and P elements into the transgingival part of the dental implant by a plasma injection method; and then, preparing the three-level micro-nano composite structure at a part in which the elements are injected.

摘要： The invention provides a dental implant system with a surface gradient microporous structure and a preparation method thereof. The dental implant system includes a non-threaded micro-cone cylindrical dental implant and an abutment, wherein the dental implant includes a microporous layer with a bionic bone trabecular structure and a base with extremely high density and mechanical strength. The dental implant system of the invention has both the precision of the internal structure and the bionic characteristics of the surface structure, which effectively improves the long-term stability after implantation, reduces the complexity of the processing process of the dental implant system, and can realize personalized and batch production.

摘要： The invention pertains to surface topographies which can be used to modulate the morphology, proliferation, biochemical functioning, differentiation, attachment, migration, signaling, and/or cell death of a cell population by physical stimulation. Such topographies can be applied in vitro and in vivo to modulate cell behavior. Specific examples include implants provided with a topography of the invention which regulates the immune response, or an implant which increases osteogenesis. The invention furthermore pertains to objects which are used in vitro to modulate cell behavior.
