Immediate Augmentation of Compromised Extraction Sockets in Chronic Periodontitis Patients: 1-Year Results of a Case Series on Volumetric and Histologic Response

The present case series evaluated three-dimensional volumetric bone tissue changes and new bone formation in compromised human extraction sockets augmented with Bio-Oss collagen and a covering collagen membrane in nine chronic periodontitis patients. After 12 months oh healing, the augmentation procedure appeared not only to compensate for bone remodeling but also to repair significant portion of the buccal wall. Overall, a mean of 49.6% new bone, 27.1% residual graft material, and 23.3% connective tissue were detected.
