Allogeneic Bone Application In Association With Platelet-Rich Plasma For Alveolar Bone Grafting Of Cleft Palate Defects

Aim: The aim of this study is to compare allogeneic bone grafts associated with platelet-rich plasma (ALBGs-PRP) to autogenous bone grafts (ATBGs) for alveolar reconstructions in patients with cleft lip and palate (CLP). Materials and Methods: The Maxillofacial Surgery Service of the Comprehensive Care Center for CLP (CCCLP) in Curitiba (Parana, Brazil). Patients: Thirty out of 46 patients with 8-12 years of age and pre- or trans-foramen unilateral clefts were operated by the same surgeon. Groups were selected randomly after coin-toss for the first surgery to be ALBG-PRP. Interventions: Pre- and post-surgery cleft defect severity was registered by a score system using superimposed digitalized peri-apical radiographs. The hypothesis indicated ABG-PRP to be similar to the ABG was proved. Results: There was no statistically significant difference (P < 0.05) in bone augmentation for the ABG-PRP group (79.88%) when compared to the ABG group (79.9%). Conclusion: ABG-PRP is indicated as a successful treatment modality to reduce the need for additional donor sites and reduce morbidity and hospital stay.
