Abstract
Objective: In this study, we aimed to determine periimplantal tissue regeneration in the use of platelet-rich fibrin in periimplantal defects. Methods: Twelve male New Zealand white rabbits were used for this study. each of the right and left tibias of rabbits Using a trephine bur (diameter 7.0 mm), monocortical defects were prepared (7 mm width,4 mm depth).Subsequently, dental implants( AL-Technology dental implants shark implants) were installed into the left and right tibia (diameter 3.0 mm, length 8 mm). In the experimental groups, the peri-implant defect was filled respectively 1-autogenous grafts, 2-PRF 3-synthetic grafts (MIS 4BONE ). The control was left in an unfilled state. Implant stability was evaluated with the resonance frequency analysis method (RFA) Results: The Ostell ISQ for the experimental groups respectively 1 -autogenous graft group 76.00±3.89,2-PRF group 75.00±3.84,3- sentetic graft group 67.00±5.72 while control group 56,33±5,12. The difference between the 2 groups (autogenous graft and prf groups) was statistically not significant while all other differences between groups are statistically significant. Conclusion: Within the limits of this study, it was found that periimplantal defects in the regeneration of Platelet-Rich Fibrin is effective as the autogenous graft
