Alveolar ridge preservation following tooth extraction using platelet rich fibrin as the sole grafting material
Ridge preservation procedure following tooth extraction is widely accepted because it can achieve optimal residual ridge resulting in greater bone dimension and better esthetics. Platelet rich fibrin (PRF) was introduced by Choukroun et al as a simple preparation technique, in which blood is collected without an anticoagulant or thrombin and immediately centrifuged only one time. The rich source of autogenous growth factors from PRF is considered to promote both soft tissue and bone regeneration. In this study, we reported a patient who received PRF as the sole grafting material for preserving the alveolar ridge dimension after tooth extraction for further dental implant placed in an ideal anatomic position. A 27 year old healthy male asked for implant restoration over the left upper posterior edentulous area. Cone beam computed tomography revealed a fenestration defect over the buccal plate of the left upper second premolar #25) (Figure 1A) The ridge preservation procedure was suggested to be performed after #25 removal and before implant placement. Under local anesthesia, after incision and flap reflection, buccal plate fenestration was noted (Figure 1B) After #25 extraction, the tooth socket was grafted with PRF as the sole grafting material for ridge preservation (Figure 1C) according to our previous report. The postoperative healing was uneventful. After 6 months, the extraction site was surgically re entered for implant placement. The socket was completely filled by a hard material, which exhibited the consistency of bone on probing (Figure 1D)
