Postextraction socket grafting using combination of demineralized freezed-dried bone allograft and platelet rich fibrin (PRF) –A Case Series

Alveolar ridge bone resorption is a biologic phenomenon that occurs following tooth extraction and cannot be prevented. Newer techniques are evolving in restorative dentistry and periodontics to treat these defects to improve the esthetics, form and functions of the dentition. Alveolar bone augmentation remains the holy grail of periodontal tissue engineering.21The purpose of this paper was to evaluate the efficacy of β- Tri Calcium Phosphate (β-TCP) and Platelet Rich Fibrin (PRF) in post extraction socket preservation. The patients presented with periodontally compromised tooth due to trauma with no labial cortical bone present which was confirmed by pre operative CBCT and was treated by extractions along with augmentation of the alveolar bone. The patient's blood was centrifuged to obtain PRF. Allograft bone graft was mixed with PRF particles and applied to fill the defect. After 6 months a Cone-Beam Computed Tomography was performed to evaluate bone regeneration. The use of PRF as cover membrane permitted a rapid epithelisation and represented an effective barrier. After 6 months the site appeared precociously healed and the bone volume increased. This new approach represents a predictable method of augmenting deficient alveolar bone.
