Abstract:Objective To explore the effect of intraoral scanning combined with 3D printing technology on implant soft tissue aesthetic effect in patients undergoing immediate implant aesthetic restoration. Methods A total of 60 patients who received immediate implant aesthetic restoration in Fengxian People's Hospital from March 2024 to March 2025 were selected as the research subjects. According to the random number table method, they were divided into the reference group and the study group, with 30 patients in each group. The reference group was treated with silicone rubber impression and gypsum model pouring restoration, and the study group was treated with intraoral scanning combined with 3D printing technology. The implant survival rate, impression time and restoration try-in time, implant soft tissue aesthetic effect, masticatory efffciency and periodontal health indexes were compared between the two groups. Results The implant survival rate of the study group was 96.67%, which was higher than 76.67% of the reference group (P<0.05). The impression time and restoration try-in time of the study group were shorter than those of the reference group (P<0.05). At 6 months after surgery, the score of PES in the study group was higher than that in the reference group (P<0.05). At 6 months after surgery, the masticatory efffciency of the study group was higher than that of the reference group (P<0.05). At 6 months after surgery, the GI and PLI of the study group were higher than those of the reference group (P<0.05). Conclusion Intraoral scanning combined with 3D printing technology can improve the implant survival rate in patients undergoing immediate implant aesthetic restoration by enhancing surgical accuracy and restoration adaptability. Meanwhile, it synchronously improves aesthetic appearance, masticatory function and periodontal health, and significantly shortens the impression time and the restoration try-in time.
