Micro-CT bone volume samples. 3D area of new bone volume formation after 4 weeks. Remaining bone graft at defect site with 3D shadow projection after 8 weeks. (a) Group 1. At 4 weeks, trabecular-shaped bone particles; at 8 weeks, little residual material was observed. (b) Group 2. Block-shaped bone particles were observed after 4 and 8 weeks. (c) Group 3. Graft material was not completely resorbed after 4 and 8 weeks.
