Figure 1. Design of the custom-made distractor (A), surgical procedure (B), radiographs before and after distraction (C,D), occlusal view of the experimental mandible (E), gross view of the distracted animal (F), and photomicrographs from H&E-stained sections from control (G,H), and groups at wk 0 (I,J), 1 wk (K,L), 2 wks (M,N), 4 wks (O,P), and 8 wks (Q,R) of the different consolidation periods are indicated. An arrow in C and solid lines in D, I, K, and M indicate the osteotomy line. An arrow in E indicates the asymmetrical occlusal attrition of the molars in experimental animals. An arrow in F indicates the midline deviation in experimental animals after distraction. OB, original bone; RB, regenerated bone; DG, distraction gap; Fi, fibrovascular tissue; Mar, marginal area; and Mid, central zone of the distraction gap. Original magnification in G, I, K, M, O, and Q, x1.6 (bar = 1.5 mm); and in H, J, L, N, P, and R, x20 (bar = 100 µm). All experiments were performed in triplicate (N = 3).
