Resorption is the action and the result of resorbing . East verb , which comes from the Latin word resorbēre, refers to that or that which receives a liquid that, before, left its structure.
For the medicine , the resorption consists of the absorption, whether partial or total, of a pathological or normal product that is collected through lymphatic or blood flow . It is called bone resorption to the procedure that leads the blood to collect the bone tissue that remove the so-called cells osteoclasts .
These cells adhere to bone tissue and destroy it as they demineralize it. The removed tissue, thus, passes to the blood . Bone resorption, in short, is a problem for the body because it weakens the bones.
The lack of physical activity and disorders such as arthritis They can cause bone resorption. It should be noted that, while osteoclasts destroy bone tissue, the osteoblasts They help your recomposition. This means that, when bone resorption occurs, the destruction that osteoclasts generate is superior to the regeneration driven by osteoblasts.
One of the sites where the result of resorption can be more easily observed that is It is the face, more specifically the area of the jaw. When a person loses their teeth, whether from an accident or from natural issues, the bone that keeps them clinging to the jaw, which is called alveolar bone a resorption process begins, since it cannot continue to exercise its function.
The alveolar bone is different from others in the human skeleton, mainly because of its ability to undergo modifications such as the one described in the previous paragraph. In addition to the loss of teeth, resorption in this case can occur due to one of the following causes: traumas ; erosion of the mucosa; the aging of the body itself; osteoporosis; periodontal disease, gingivitis or periodontitis.
In the absence of dental pieces, the fastest and safest way to prevent bone resorption is the application of implants. While some people prefer to opt for bridges and removable prostheses, it is important to note that this requires the removal of two or more teeth, and that dentures should be replaced with some periodicity anyway; As if this were not enough, they also do not prevent the resorption process from progressing. The implant seems to be the most effective method, since it includes the replacement of the root, with the added advantage of preventing the teeth natural move.
The passage of time can be crucial in a case of resorption of alveolar bone. Over the first 3 years, approximately, after the loss of the dental pieces, the loss of thickness and height can reach a 60% , after which the rhythm decreases considerably, until reaching a 1% by year.
If implants are not placed soon, modern medicine offers the possibility of performing bone grafts , to compensate for the decrease that the bone alveolar has suffered in volume. However, when the distance between the loss of the teeth and the implant is considerable, the procedure can be greatly complicated, since the wear not only causes a difference in height but also in depth (the jaw appears to shrink high and long , giving the feeling that the chin retracts).
Beyond the diseases or of exercise , the bone resorption process is also linked to the calcium level existing in the body. When the level of calcium is reduced, the segregation of a hormone is stimulated, which, in turn, promotes the development and action of osteoclasts, which release calcium present in bone tissue through resorption. That's why eating calcium-rich foods, such as milk, cheese and nuts, is healthy for the bones.
