Objective: This study was performed to compare between the influence of fragmented periosteal graft and covering periosteal graft on bone healing. Methods: Twenty healthy patients were subjected to removal of impacted mesioangular lower third molar. Those patients were divided into two equal groups according to the application of the periosteal free grafts on the socket. Group (I) comprised ten patients, in whom the periosteal free grafts were sutured to the mouth of the socket after odontectomy of the tooth with cambium layer facing the socket. Group (II) comprised ten patients, in whom the periosteal free grafts were fragmented in Petri dish and applied inside the socket. Conclusion: There was no difference between the two techniques of the free periosteal graft on bone healing.
