Implication

Comparative evaluation shows similar healing in xenograft materials for calvarial and mandibular defects, suggesting effective options for bone repair.

Key Points

This research aims to compare the effectiveness of bovine-derived and porcine-derived xenografts in facilitating bone healing in animal models.
Evaluated healing at 6 and 12 weeks in rabbit calvarial defects and 24 weeks in canine mandibular defects.
Used micro-computed tomography to measure mineralized tissue fill and volumetric maintenance.
Conducted histological analysis using hematoxylin and eosin (H&E) staining for qualitative observations.
Defect closure in rabbits did not significantly differ between xenograft materials at both timepoints.
In dogs, new bone formation was similar between graft types, with a trend favoring the bovine-derived graft for residual graft.
Vertical volume maintenance trended higher with bovine-derived xenograft, while horizontal maintenance was comparable.
