ABSTRACT

Aim: The current study was conducted to evaluate the effect of platelet-rich fibrin matrix (PRFM) treated with silver nanoparticles (AgNPs) on enhancing the healing of the experimentally induced bone gap in a rabbit model.

Materials and Methods: Twenty healthy male local rabbits aged between 6 and 8 months, their weights between 1.5 and 2 kg were used in this study and divided randomly into four equal groups, under general anesthesia (1 cm), bone gap was induced in the tibia bone to create a critical bone defect and leave it without any treatment in the first group (control group). While in the second group the bone gap was filled with PRFM; in the third group, the gap was filled with 0.3 ml AgNPs; and in the fourth group, the gap was filled with PRFM treated with AgNPs.

Results: There was no infection at the operation site in all experimental animals, and the radiograph images showed periosteal and endosteal reaction; the gaps were bridged faster in the fourth group as compared with the other groups. The histological examination showed lamellar bone with haversian canal completely filled the fracture gap and contact with old bone in the fourth group as compared to other groups.

Conclusion: Using a combination of PRFM and single nucleotide polymorphisms together gave better acceleration in the bone healing process than using each one of them separately.
