Abstract: Objective To investigate the feasibility and prognosis of immediate implant placement and immediate restoration in patients with type 2 diabetes by establishing an animal model. Methods The type 2 diabetic animal model was established using New Zealand rabbits as the experimental group and healthy New Zealand rabbits as the control group. Both groups underwent immediate implantation and immediate repair. Micro-CT scanning, hard tissue section, and detection of relative inflammatory factors by real-time quantitative PCR were used to compare prognosis and histological remodeling between the two groups. Results The success rate for immediate implant placement and immediate restoration was 90% in both groups. In the early postoperative period (1~2 months), the peri-implant bone of the experimental rabbits in the T2DM group was significantly different from the control group in various microscopic parameters, in the meantime, the expressions of IL-6, IL-33 and TNF-α were significantly higher than those of the control group. Conclusion Animal experiments have shown that the immediate implant placement and immediate prosthesis are safe in type 2 diabetic animal models. However, attention should be paid to the slow formation of osseointegration and obvious inflammation of the soft tissue around the implant in the early stage.
