Abstract Objective: To analyze the role of modified platelet-rich fibrin (PRF) in socket preservation for the preservation of alveolar bone quantity and maintenance of alveolar bone morphology.Methods: A total of 105 patients undergoing socket preservation surgery from September 2021 to September 2023 were randomly divided into an observation group (n=52, treated with modified PRF) and a control group (n=53, conventional treatment). Clinical treatment outcomes, changes in alveolar bone quantity, and alveolar bone morphology before and after treatment were compared between the two groups.Results: Compared with the control group, the observation group had a shorter healing time (P<0.05), and higher wound healing rates at 1 week and 2 weeks postoperatively (P<0.05). At 4 months postoperatively, there were no significant differences in bone crest level (BC1) between the two groups (P>0.05), but the observation group had higher mean gray value (BD2) and bone gain (BG) compared to the control group (P<0.05), while BC2 was lower in the observation group (P<0.05). At 6 months postoperatively, the observation group showed greater improvements in alveolar bone width, height, density levels, and improvement rates compared to the control group (P<0.05). At 3 months postoperatively, the sulcus bleeding index (SBI) was lower in the observation group than in the control group (P<0.05).Conclusion: Modified PRF used in socket preservation surgery demonstrates good osteogenic effects, aids in wound healing, and plays a beneficial role in preserving alveolar bone quantity and maintaining alveolar bone morphology.
