From: Bone augmentation for cancellous bone-development of a new animal model
Histomorphometrical evaluation. Histomorphometry was used to quantify the percentage of new bone, old bone, granulation tissue, and residual augmentation material within the area of interest. For standardization of the evaluated area four circles of 6 mm in diameter were chosen around the tip of the needle. Cortical bone area was excluded from the analysis (black area in circle 1). The rest of the circle was considered as 100%. Circles including growth plate were completely excluded from the analysis (circle 3 + 4).
