Study on the Role of Modified Platelet-Rich Fibrin in Socket Preservation for Preservation of Alveolar Bone Quantity and Maintenance of Alveolar Bone Morphology
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,conven-tional treatment).Clinical treatment outcomes,changes in alveolar bone quantity,and alveolar bone morphol-ogy 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 ob-servation 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.
