| Immature compact bone does not contain osteons and has a woven structure. |
| If the osteons are very thick, we recommend using the rotating diamond burr for preliminary treatment of the outer compacta. |
| Cement lines are found in all types of bone, as well as in osteons, and in general they indicate lines at which new bone was deposited on an old surface. |
| It forms around a framework of collagen fibres and is eventually replaced by mature bone in a remodeling process of bone resorption and new bone formation that creates the osteons. |
| Active cortical remodeling was present, with the osteons filled with new bone centrally as evidenced by the darker histologic staining. |
