Objective To explore and analyze the clinical therapeutic effect of i-PRF combined with Bio-OSS bone meal extraction site preservation technique in oral implant patients and its effect on aesthetic index and subjective satisfaction score. Methods a total of 41 patients admitted to our hospital from May 2018 to March 2020 with minimally invasive extraction of single tooth were selected as the research objects, and they were divided into control group (21 cases) and experimental group (20 cases) according to random number table method. Patients in the control group were treated with conventional treatment after tooth extraction, while patients in the experimental group were treated with I-PRF combined with Bio-OSS bone meal extraction site preservation technology. The implant retention rate, bone binding rate, and bone absorption scores of red aesthetic index (PES) and white aesthetic index (WES) 1 and 3 months after surgery were compared between the two groups. Results In this study, there were no significant differences in implant retention rate, vertical bone absorption and chewing efficiency 6 months after operation between the control group and the experimental group (P > 0.05). Conclusions In the treatment of patients with oral implants, the combination of I-PRF and Bio-OSS bone meal extraction site preservation technique can help improve patients aesthetic index and subjective satisfaction score.
