Figure 4

Volumetric analysis using CAE. (A) Non-cleft side data were mirrored (blue), and then the original cleft data were subtracted to identify cleft morphology and volume. Postoperative data (pink) was registered with the original cleft to identify the graft and newly formed alveolar bone. Postoperative graft volume changes of patients who underwent BMMNCs/β-TCP and ICBG grafting are presented in (B) and (C), respectively. (D) Bone formation ratio of the two groups at 6 and 12 months postoperatively. DV, defect volume; BV, bone volume.
