Methods: Twenty white Wistar rats aged 100 days underwent surgery to create a bone defect measuring 2.5-3.0 mm in length in the diaphysis of the fibula. After thirty days, the animals were divided into two groups. Group I received periosteum along with a collagen membrane, while Group II received only a collagen membrane. The animals were X-rayed before the implant surgery and 15 or 30 days post-operation. Results: The results demonstrated that free periosteum graft in combination with collagen membranes was not efficient in the repair of bone defects. Conclusion: We suggest that nonvascularized periosteal grafts do not show potential to form new bone, and that making the implant 30 days after the creation of the bone defect may have interfered negatively in osteogenic process.
