THE EFFECT OF PLATELET RICH-FIBRIN WITH AND WITHOUT AUTOGENOUS BONE GRAFT ON BONE REGENERATION FOLLOWING ENUCLEATION OF MAXILLARY CYSTS

Introduction: Reconstruction of bony defects represents a challenging problem for the surgical community. Autologous bone grafting involves utilizing bone obtained from the same individual receiving the graft. Bone can be harvested from the mandibular symphysis (chin area). Autologous platelet rich-fibrin (PRF) is considered to be a healing biomaterial, which has been widely used for accelerating soft and hard tissue regeneration. The use of bone graft in combination with platelet rich-fibrin helps in rapid bone regeneration when compared to natural healing. Objectives: is to compare the effect of platelet rich-fibrin with and without autogenous bone graft on bone regeneration following enucleation of maxillary cysts. Materials and methods: Twenty-one patients with maxillary cysts had been treated with autogenous bone graft with platelet-rich fibrin versus platelet rich-fibrin without autogenous bone graft following cyst enucleation, and the follow up was done for 6 months using Cone Beam Computerized Tomography (CBCT) to evaluate bone regeneration in the defect site. Results:All groups showed increasing in bone density. Group A showed the best results with a mean 330.71, while Group B showed results with a mean 184. Group C showed results with a mean 117.71. Conclusions: PRF can be considered a healing biomaterial, as it features all the necessary parameters permitting bone regeneration without any adverse reaction. The addition of autogenous bone graft to PRF accelerates the regenerative capacity of bone. They give a predictable clinical and radiographic evidence of bone formation and faster healing than using PRF alone.
