Does Platelet-Rich Fibrin Enhance Bone Quality and Quantity of Alveolar Cleft Reconstruction?

Abstract

Recently, platelet-rich fibrin (PRF) was described as a second-generation platelet concentrate. PRF is known as a rich source of autologous cytokines and growth factors and is universally used for tissue regeneration in clinical medicine. The aim of the current study was to evaluate the effect of PRF on the quality and quantity of bone formation in unilateral maxillary alveolar cleft reconstruction. Twenty-four patients with unilateral alveolar cleft underwent bone reconstruction. Patients were randomly divided into two groups. Group A consisted of patients grafted with PRF combined with autogenous anterior iliac crest bone graft. Group B patients were grafted using autogenous bone graft alone (control group). Computed tomography was performed 6 months postoperatively to assess the quality and quantity of the newly formed bone. The percentage of newly formed bone (quantity) in group A ranged from 79.74% to 88.4%, with a mean percentage of 82.6% ± 3.9%. In group B, the percentage of bone formation ranged from 60.3% to 76.4%, with a mean percentage of 68.38% ± 6.67%. There was a statistically significant increase in the percentage of newly formed bone in group A. The mean bone density (quality) of the newly formed bone was lower in group A than group B, but the difference was not statistically significant (P < .05). PRF in combination with autogenous bone was beneficial in improving the volume of newly formed bone in alveolar cleft reconstruction and does not enhance bone density.
