The invention discloses a gradient material for guiding regeneration of periodontal hard and soft tissues, and a preparation method of the gradient material. The gradient material is constructed by combining an electrostatic spinning technology with a biological 3D (three dimensional) technology. A micropore structure of an electrostatic spun fibrous membrane can prevent gingival fibroblasts frommigrating to a root surface to play a mechanical barrier role and facilitate transmission of nutrition and metabolism substances; and individualized repair of alveolar bone can be achieved according to clinical requirements since a structure and a shape of a 3D printing scaffold layer are highly designable. The method is simple and stable in preparation technology, and the gradient material integrates a periodontal guided tissue regeneration membrane and an alveolar bone repair scaffold material and has a potency to achieve clinical customized treatment. The gradient material has a good effectof guiding the repair of the hard and soft tissues in vivo and can be better applied to the synchronous regeneration and repair of the alveolar bone and the periodontal tissues.

The invention relates to a pure titanium dental implant, which is characterized in that a plurality of micron-sized grooves are formed in the surface of the pure titanium dental implant, and nanotubesperpendicular to the central axis of the dental implant are arranged in the grooves. A width of each groove is 50 [mu] m, a depth of each groove is 10 [mu] m, and the distance between adjacent grooves is 50-53 [mu] m. The method comprises the following steps: firstly, a middle groove in the surface of the dental implant is manufactured; then manufacturing the nanotube is manufactured on the groove so that the surface of the top of the nanotube is an inclined plane, and a contact surface between the inclined plane and a bone tissue interface and between the inclined plane and a soft tissue interface is large; the contact surface between the nanotube and a bone tissue interface and between the nanotube and a soft tissue interface is large, the micron-sized groove can induce bone tissue cells and soft tissue cells to better grow along the grooves, and the nanotube is also beneficial to adsorption of protein, oxygen and nutrients. The size of the groove is just slightly smaller than thatof the bone marrow stromal stem cells and gingival fibroblasts which are not stretched, so that the cells cannot fall into the groove, and the cells can grow along the groove. The proliferation of gingival fibroblasts and the expression of soft tissue closure related genes can be promoted, so that the effects of osteogenesis and soft tissue closure are achieved.

The invention relates to a dental implant with a nano antibacterial structure ring at a gingival penetrating part and a processing method of the dental implant. The gingival penetrating part of the dental implant has a three-level micro-nano composite structure, and the three-level micro-nano composite structure endows the surface of the gingival penetrating part of the implant with functions of promoting adhesion and proliferation of gingival fibroblasts and gingival mesenchymal stem cells and inhibiting adhesion and growth of various oral bacteria. The preparation method comprises the following steps: firstly, injecting bioactive, wear-resistant or corrosion-resistant C, N, Ca and P elements into the gingival penetrating part of the dental implant by a plasma injection method; and then manufacturing the three-level micro-nano composite structure at the part where the elements are injected. According to the invention, the surface with the bioactive components and the three-level micro-nano composite structure is prepared at the gingival penetrating part of the implant, so that the adhesion and proliferation of the gingival fibroblasts and the gingival mesenchymal stem cells can be effectively promoted, the adhesion and growth of various oral bacteria on the implant can be inhibited, the periodontal infection risk after the implant is implanted can be effectively reduced, and the implantation success rate is improved.
