Disorders of the bone may involve the osseous tissue. Physical therapy can help some people rebuild strength and bone density lost to disorders such as osteoporosis. Osseous tissue is the primary constituent of bone, creating the mineral matrix that makes bones hard, strong, and lightweight.

All procedures designed to modify and re-shape defects and deformities in the bone surrounding the teeth are called osseous surgery. The most common pattern of bone loss is reduction in height of bone.
