Department of Stomatology, Nanhua Hospital Affiliated to University of South China, Hengyang, Hunan 421001 [Abstract] Objective To explore the influence of bone-level implant restoration treatment on the red and white aesthetic effect, periodontitis indicators and postoperative complications of patients with dentition defects. Methods The research subjects were 100 patients with dental arch defects admitted to our hospital. The inclusion period is from January to December 2024. They were grouped according to different restoration methods: the observation group (n=50, bone-level implant restoration treatment) and the control group (n=50, traditional restoration method). The pink aesthetic index (PES) and white aesthetic index (WES) of the patients were evaluated respectively at 3 months, 6 months and 12 months after repair, and the levels of inflammatory factors in gingival crevicular fluid [interleukin-1 β (IL-1β), tumor necrosis factor -α (TNF-α) and matrix metalloproteinase-8 (MMP-8)] were detected. Record the occurrence of complications. Results Twelve months after repair, the total scores of PES and WES in the observation group were higher than those in the control group (P < 0.05); At each time point after repair, the levels of IL-1β, TNF-α, MMP-8 in the gingival crevicular fluid of the observation group and the VAS score were all lower than those of the control group (P < 0.05). Twelve months after restoration, the incidence of pulpitis and complications in the observation group was lower than that in the control group (P < 0.05). Conclusion Compared with traditional soft tissue-level implants, bone tissue-level implant restoration can more effectively improve the red and white aesthetic effect of patients with dentition defects, reduce the inflammatory response of peri-implant tissues, enhance patient comfort, and lower the incidence of pulpitis and complications. It has higher clinical promotion value.
