Periodontal Responses to Augmented Corticotomy with Collagen Membrane Application during Orthodontic Buccal Tipping in Dogs

Figure 3

Micrographs of buccolingual sections from the control ((a), (c)) and test sides ((b), (d)) in the maxilla ((a), (b)) and mandible ((c), (d)). Red arrowheads indicate bone formation over DBBM particles in the crest area. White arrowheads in (a) (control) indicate exophytic new bone formation from the buccal bone wall by bone-derived mesenchymal matrix that formed irregular bone surfaces. White arrowheads in (b) (test) indicate new bone formation from the buccal bone wall by bone-derived mesenchymal matrix that formed even bone surfaces. Masson’s trichrome stain was used, and the original magnification was ×12.5.
