This study aims to examine how collagen membranes with varying thickness affect biological responses during guided bone regeneration.
Standardized mandibular defects in beagle dogs were grafted with bone substitutes and covered with collagen membranes.
Two types of collagen membranes with different thicknesses were used, and tissue samples were analyzed at 8 and 16 weeks.
Immunohistochemical markers related to bone healing, inflammation, and remodeling were assessed.
At 8 weeks, the FM group had a trend of higher CD206-positive cells but no significant differences in other inflammatory markers.
The SM group showed significantly greater collagen type I deposition, though mostly represented unmineralized matrix rather than bone formation.
TRAP-positive cells were more frequent in membrane-covered groups, suggesting remodeling activity.
