Further, the diameter of the bone grafting section is 3mm, and the diameter of the base platform section is 5 mm.
Furthermore, the periphery of the bone grafting section is provided with at least 4 grooves with trapezoidal sections at equal included angles. The groove can achieve the self-tapping and locking effects when the bone grafting section is screwed into the alveolar bone.
Further, the personalized repair network segment may have a variety of design approaches. For example, the whole body is a porous component, and the sufficient strength is ensured by adjusting the reasonable porosity, so that the autogenous bone of the patient can grow into the personalized repair network segment more easily, and the whole personalized dental implant is more stable. For another example, the personalized repair network segment comprises a connecting rod and a shell, the arc-shaped curved surface is the shell, a cavity is arranged in the shell, the connecting rod is positioned in the cavity, and two ends of the connecting rod are respectively connected with the base platform segment and the bone grafting segment. The base platform section and the bone grafting section are connected by the connecting rod without considering the strength of the porous part; the cavity in the shell can be filled with anti-inflammatory and bacteriostatic medicines or medicines which are helpful for bone growth in advance, and can also be filled with autologous bone powder in advance. The holes are uniformly distributed on the shell, so that the medicine in the cavity can be released, and the autogenous bones of the patient can grow into the shell. Preferably, the thickness of the shell is 0.2-0.3 mm.
Furthermore, a horn-shaped transition structure is arranged at the position where the hexagonal groove is connected with the circular truncated cone, and the diameter of the horn-shaped transition structure is gradually reduced from the end face of the circular truncated cone to the direction of the hexagonal groove. The trumpet-shaped transition structure avoids stress concentration.
Further, the personalized dental implant is a pure titanium component or a titanium alloy component.
The utility model discloses a combine dental implant and restoration net be in the same place, in the existing section screw in alveolar bone of planting the bone, guaranteed dental implant's initial stage stability, have the fixed required bone grafting material of restoreing the bone defect of individualized restoration network segment simultaneously again. The arc-shaped curved surface of the personalized repair network segment is personalized by combining the finite element analysis result of the personalized model of the patient, and simultaneously, bones are induced to grow into holes of the arc-shaped curved surface, so that better biocompatibility and combination stability are achieved. Finally, the effects of obviously reducing the times of operations and the difficulty of the operations are achieved, meanwhile, the recovery time of the patient is shortened, and the success rate of the planting is improved.
