Abstract:
The jaw bone receive complicated forces not only through the muscles, but through the teeth directly. Therefore, it is thought that the morphology of the trabecular bone in jaw is greatly effected by the teeth. The structures of the trabecular bone are constructed in order to support the teeth. With loss of the teeth, both width and volume of the trabecular bone are reduced and the trabecular bone run in the irregular course. Consequently, these findings suggested that mechanical forces change to the structures of trabeculare in jaw bone.

Spongy Bone
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

Compact Bone
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...
