Objective: To analyze and evaluate the clinical efficacy of different treatment options for patients with peri-implant infection. Methods: The study period was from June 2019 to June 2020. Seventy-six patients with peri-implant infection that were treated in Stomatological Hospital of Hefei were selected as study samples. The patients were divided into a research group and a control group by random number table method in which the sample size of each group was n=38. Patients in the control group were treated with drugs combined with ultrasonic cleaning while patients in the research group were treated with guided bone regeneration combined with flap curettage. The indicators of the two groups were compared and analyzed. Results: The plaque index (PLI), probing depth (PD), and sulcus bleeding index (SBI) of the two groups after treatment were lower than those before treatment (P < 0.05). There was no significant difference between the groups (P > 0.05). However, the height of the implant marginal bone of the study group after treatment was higher than that of the control group (P < 0.05). Conclusion: The use of guided bone regeneration combined with flap curettage for patients with infection around dental implants promotes the fusion of bone and implants. The clinical effect was significant and this should be comprehensively promoted in medical institutions at all levels.
