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 sharkimplants)  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. İmplant 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
