bone |
os |
 |
| 1. the material of the skeletons of most vertebrate animals; the tissue composing bones. 2. dense, hard, and slightly elastic connective tissue in which the fibers are impregnated with a form of calcium phosphate similar to hydroxyapatite. Bone tissue makes up the 206 bones of the human skeleton. 3. any single element of the skeleton such as a rib or femur |

atrophy, bone- |
atrophie osseuse |
|
| bone resorption internally (in density) and externally (in form) (for example, of residual ridges). 2. a loss of bone substance or volume. Atrophy of bone ordinarily occurs without a corresponding change in the volume or external dimensions of bone, but the mass of bone tissue may be reduced by as much as 75%. The internal architecture of the bone gradually becomes attenuated and finally disappears. Atrophied bone is brittle and has a more spongy consistency than normal bone. In cross-section the cortex is thin, and the periosteal surface is smooth and unchanged, but the intramedullary substance is composed of a yellow, fatty, cancellous bone tissue. Bone atrophy may be systemic, regional, or local. |

bone recession |
résorption osseuse, atrophie osseuse |
|
| apical progression of the level of the alveolar crest associated with inflammatory and dystrophic periodontal disease; a bone resorption process that results in decreased osseous support for the tooth. |

bone resection |

| |
bone resorption |
résorption osseuse |
|
| 1. destruction or solution of the elements of bone. 2. loss of bone resulting from the activity of multinucleated giant cells, the osteoclasts, which are noted in irregular concavities on the periphery of the bone (Howship's lacunae). |
