Immediate Augmentation of Compromised Extraction Sockets in Chronic Periodontitis Patients: 1-Year Results of a Case Series on Volumetric and Histologic Response.
Int J Periodontics Restorative Dent. 2019 Mar/Apr;39(2):245-251. doi: 10.11607/prd.3337.
Abstract
The
present case series evaluated three-dimensional volumetric bone tissue
changes and new bone formation in severely resorbed extraction sockets
augmented with Bio-Oss collagen and a covering collagen membrane in nine
chronic periodontitis patients. Healing was by secondary intention.
After 12 months of healing, the augmentation procedure appeared not only
to compensate for bone remodeling but also appeared to repair a
significant portion of the buccal wall. The mineralized tissue filled
the 91.49% ± 6.77% of the maximum volume for regeneration. Overall, a
mean of 49.6% new bone, 27.1% residual graft material, and 23.3%
connective tissue were detected.
