Abstract
BackgroundPlatelet-rich fibrin (PRF) is the second generation of platelet concentrates and is used in many areas of dentistry. However, whether PRF is effective for alveolar ridge preservation remains controversial. The authors conducted research to evaluate the potential of PRF to preserve the alveolar ridge. MethodsA comprehensive literature search was conducted in MEDLINE, Cochrane Central Register of Controlled Trials, and Embase. Only randomized controlled trials were included. A systematic review was made for postoperative pain, soft-tissue healing, bone density, horizontal and vertical ridge dimension changes, and histologic analysis. The meta-analysis was performed on the alveolar osteitis, mesial and distal bone height changes, and bone fill with Review Manager Version 5.3 software. ResultsAmong the 588 eligible articles found in the initial search, 7 published studies from 2012 through 2019 were included. The authors’ qualitative analysis showed that PRF may play a positive role in reducing postoperative pain and ridge dimension changes after tooth extraction. Among the 7 articles, only 2 trials assessed the effect of PRF on the alveolar osteitis, mesial and distal bone height changes, and bone fill. Results of our meta-analysis showed that smaller mesial bone height changes (standard mean difference, –1.07; 95% confidence interval, –1.92 to 0.22) and a greater percentage of bone fill (standard mean difference, 0.82; 95% confidence interval, 0.32 to 1.33) were observed in the PRF group. ConclusionsGiven the potential value of PRF, consideration should be given to PRF after tooth extraction. However, more high-quality trials are necessary to evaluate the exact role of PRF. Practical ImplicationsBased on the authors’ results, the usage of PRF was suggested in alveolar ridge preservation.
