Background: Platelet-rich fibrin is a second-generation platelet concentrate obtained through a technique that allows precipitating a platelet segment from a peripheral blood sample. PRF is widely used to improve bone regeneration processes.
Objective: To present a method article where socket preservation was accomplished by the combination of local socket detoxification with Tetracycline; PRF and bone grafts, for bone regeneration.
Methods: Method article where 10 patients underwent dental extractions. The socket preservation was performed with Tetracycline and the combined use of PRF with heterologous bone.
Results: It was possible to obtain PRF membranes of excellent quality out of the intervened patients, which led to adequate bone preservation in 80% of the sockets.
Conclusion: By using the presented method, it was possible to preserve on average 80% of the alveolar bone.
