Introduction:
Sinus floor augmentation for posterior maxillary ridge augmentation to allow implant placement is a known procedure but with no exact consensus on the ideal grafting techniques. We hereby propose the use of A-PRF with Xenografts for sinus elevation.
Methodology:
Eight patients were include in this study and were randomly allocated into one of the groups ; Control Group (Xenograft only ) and a Study Group (a-PRF with the xenograft). The patients were prepared in the routine method and CBCTs ordered , and the study group patients and blood drawn and prepared according to the reported protocol to prepare a-PRF. After 6 months the patients were recalled CBCTs prdered and the implants placed with the elevated sinus floor , bone biopsies were also done at this point.
Results
Results of the study showed comparable bone height after 6 months in both groups with that of the study group slightly higher but without a statistically significant difference. None of the patients reported signs of infection or perforation postoperatively.
Conclusions:
Results of our study agree with reports proving that a-PRF promotes bone healing. Within the limitations of this trial; we hope to carry on our research in comparing the different platelet concentrates and their effect on bone regeneration. These may provide an autologous, cheap and easily prepared material to cover bone graft for ridge augmentation in maxillary sinuses or otherwise.
