Bone Resorption During Submerged Healing After Guided Bone Regeneration : A Prospective Case Series

Objective
The aim of this study was to evaluate bone resorption quantitatively during the healing period subsequent to ridge augmentation.
Results
Overall changes in alveolar bone with a mean resorption rate of 19.8%.Vertical mean resorption rate of 22.8%, horizontal 18.7%.
4 sites with post-operative complications including membrane exposure showed an average of 42.1% resorption rates.

Conclusion
Loss in graft quantity was observed after ridge augmentation using an allograft and nonresorbable membrane during submerged healing before implant placement. Further studies with larger sample sizes are recommended to confirm its findings.
