Abstract Objective: To investigate the application effect of mixed filling of bone cavity with concentrated growth factor (CGF) and allogeneic bone particles combined with biofilm covering in bone augmentation for odontogenic cysts. Method: A total of 60 patients with odontogenic cysts who were admitted to the Stomatology Department of Shangrao People's Hospital from July 2021 to December 2022, and needed bone augmentation during operation were selected and divided into observation group (n=30) and control group (n=30) according to random number table method. The observation group was treated with biofilm covering after mixed filling of bone cavity with CGF and allogeneic bone particles, while the control group was treated with mixed filling of bone cavity with CGF and allogeneic bone particles. Clinical efficacy, postoperative infection, postoperative recovery of teeth with loss of function, and Vancouver scar scale (VSS) scores were compared between the two groups. Result: The total treatment effective rate in the observation group (90.00%) was higher than that in the control group (66.67%) (P<0.05). Three months after operation, there was 1 case of mild infection and 3 cases of severe infection in the observation group, 3 cases of mild infection and 10 cases of severe infection in the control group, the difference in infection between the two groups was statistically significant (P<0.05). The recovery of affected teeth in the observation group was better than that in the control group (P<0.05). The VSS scores of the observation group were lower than those of the control group at 1 week, 2 weeks and 4 weeks after operation (P<0.05). Conclusion: Mixed filling of bone cavity with CGF and allogeneic bone particles combined with biofilm covering can enhance the therapeutic effect of bone augmentation on odontogenic cyst, promote the recovery of affected teeth, reduce the incidence of postoperative infection, and inhibit scar formation after operation.
