Could a blood clot membrane replace collagen for better dental implants?

This study tested whether a special membrane made from a patient's own blood (extended platelet-rich fibrin, or e-PRF) works as well as a standard collagen membrane for preserving the jawbone after a tooth is pulled. Fifty-five adults who needed a tooth extraction and later a dental implant took part. The goal was to see if the e-PRF membrane could prevent bone shrinkage just as well as collagen, potentially offering a natural and cheaper alternative.
