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.
Materials and Methods:
Sixteen patients requiring vertical ridge augmentation before implant placement were recruited in the study. The study used an allograft and nonresorbable membrane. A custom acrylic stent was used to measure changes in bone volume. Augmented bone was compared with remaining bone 6 months after guided bone regeneration (α = 0.05 by means of the paired t test).
Results:
All sites following the six months post-surgery were analyzed. Overall changes in alveolar bone were observed with a mean resorption rate of 19.8% (p
