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

Figure 2

Representative micrographs for measuring the buccal tipping angle ((a), (c)) and bone area ((b), (d)) in the maxilla ((a), (b)) and mandible ((c), (d)). Red, yellow, and black arrows indicate the bone-derived, PDL-derived, and buccal mesenchymal matrices, respectively. Intersection of the yellow lines represents buccal tipping angle ((a), (c)). New bone area (%) was calculated by subtracting old bone area from total bone area. Masson’s trichrome stain was used, and the original magnification was ×12.5.
