Higher magnification histology images of machined group ((a) and (b), black boxes in Figure 6(a), ×40) and RBM group ((c) and (d), black boxes in Figure 6(b), ×40). (a) An active bone cone with osteoclasts (black arrow) and osteoblasts (white arrow) is in old lamella bone. (b) There are several active bone cones which have osteoclasts (black arrow) and osteoblasts (white arrow) in old lamella bone and new bone. (c) There are few bone cones which show unclear osteoclasts and osteoblast (black and white arrows). (d) Although there are several bone cones in old lamella bone, they are less active than (b) and they have unclear osteoclast (black arrow) and osteoblast (white arrow).
