Impact of Cortical Perforations of Contiguous Donor Bone in a Guided Bone Augmentation Procedure: An Experimental Study in the Rabbit Skull

Abstract

In the present model, as observed 3 months postoperatively, cortical perforations of contiguous donor bone or degree of immediate blood fill of an extracalvarial experimental space were not found to enhance augmented tissue volume beyond the skeletal envelope. Although there was a much higher mean value for bone density of augmented bone in the test sites, the large variations failed to show significant intergroup differences.
